Our suite of products empowers enterprises to manage, transact, and leverage cryptocurrencies with ease. Whether your business is looking to integrate cryptocurrency solutions or enhance existing financial operations, Cregis equips you with state-of-the-art technologies designed to optimize efficiency and security. From self-custody wallets to payment engines and financial services, Cregis is here to support your business in navigating the evolving digital economy with confidence.

Self-Custody MPC Wallet

Cregis MPC Wallet is a crypto asset management tool designed for users to have full control over their digital assets. Unlike custodial wallets, the private keys for self-custody wallets are held by the users themselves, ensuring that Cregis has no access to their private keys or funds, thus maximizing security and privacy. The wallet supports multiple cryptocurrencies and blockchain networks, along with robust security features.

Wallet as a Service

Cregis offers a standardized wallet API that allows businesses to create wallet addresses and conduct cryptocurrency transactions without the need to develop or maintain the underlying wallet technology. These addresses are fully owned by the business and can be easily consolidated. By leveraging Cregis’s wallet API, businesses can focus more on designing user flows and interfaces while enhancing brand marketing efforts, ultimately creating greater value for their products.

Cregis Payment Engine

Cregis is committed to addressing the various challenges of traditional acquiring for merchants, offering a range of crypto acquiring tools including checkout pages, QR codes, POS machines, and invoices to help merchants break free from the constraints of traditional banks. Cregis supports multiple blockchain networks and fiat currencies, providing real-time settlement with T+0 processing, significantly enhancing capital efficiency while reducing cross-border settlement costs.

Cregis Financial Services

Cregis Card combines cryptocurrency and traditional credit card functions. Available as virtual and physical cards, users can top up with crypto and make everyday purchases. The card supports online and offline payments, along with integration with PayPal, Apple Pay, and Google Pay. Cregis also offers multi-card fund sharing and real-time expense management, providing a seamless global payment experience.

Cregis utilizes advanced MPC (Multi-Party Computation) shard technology to enhance the security of private keys by dividing them into multiple shards. In a single-signature wallet, these MPC shards are securely stored across both the local device and a Trusted Execution Environment (TEE), ensuring that no single entity holds the complete key. For multi-signature wallets, the shards are distributed across different local devices, further enhancing security by decentralizing control. Each time a transaction is made, the MPC shards are computed in various locations and combined with those stored in the cloud, ensuring a highly secure and efficient signing process.

Your wallet automatically generates two sets of recovery phrases because different blockchains use different cryptographic standards. To ensure the security and full compatibility of your assets, we employ a dual-recovery-phrase design.

Here are the specific reasons:

• Technical Necessity

  • Different blockchains use different encryption standards.

  • First recovery phrase (ed25519): Supports high-performance blockchains like Solana (SOL), Sui (SUI), Ton (TON), Aptos (APT), and Cardano (ADA).

  • Second recovery phrase (secp256k1): Supports Bitcoin (BTC), Ethereum (ETH), and other EVM-compatible chains (e.g., BSC, Polygon).

  • Since the two encryption algorithms (ed25519 and secp256k1) are incompatible, separate recovery phrases are required to manage assets across different chains.

• Security Design

  • Asset isolation reduces risk: The two recovery phrases are completely independent. Even if one is compromised, the assets managed by the other remain secure.

  • Prevents asset loss due to derivation errors: For example, using an ed25519 recovery phrase to restore a secp256k1-based wallet will fail.

What You Need to Know

• Backup both recovery phrases—neither can be omitted. Losing one may result in irreversible loss of assets on certain chains.

• When recovering your wallet, you must import both phrases to regain full access to all assets across supported chains.

Why Can’t They Be Combined Into One? The blockchain industry has not yet unified cryptographic standards. Our dual-recovery-phrase solution ensures 100% security and compatibility for your assets. Should industry standards evolve, we will promptly optimize the user experience.

I Only Use Bitcoin/Ethereum—Why Do I Need to Back Up the ed25519 Phrase? Even if you don’t currently use chains like Solana or Cardano, storing both phrases ensures future flexibility. The ed25519 phrase will be essential if you ever wish to interact with these high-performance blockchains.

The key differences between Advanced Mode and Standard Mode lie in the protocol used and the fee control mechanism:

• Advanced Mode: This mode adopts the EIP-1559 protocol, which uses a new fee calculation method. It allows for faster transaction confirmation and theoretically reduces fee volatility. Advanced Mode is ideal for users requiring high-priority confirmations. Users can customize Max Fee (maximum fee) and Max Priority Fee (priority fee) for precise control.

• Standard Mode: Based on the traditional gas fee structure, this mode requires manual input of Gas Price and Gas Limit. It offers less flexibility but suits users unfamiliar with EIP-1559 or those who prefer the traditional setup.

Compared to Standard Mode, Advanced Mode provides more cost savings and stable performance, while Standard Mode continues the conventional fee-setting approach.

No, the auto-signing feature in Cregis requires the application to remain open to function. This ensures the security of the signing process and the real-time handling of private key shards. If Cregis is closed, the auto-signing feature will not operate.

The system will prioritize and execute the policy that was created or updated most recently.

Currently, only the TRON network offers a proxy resource feature, allowing team account balances to cover resource fees. Other networks still require the wallet's cryptocurrency balance to pay for gas fees.

The TON blockchain uses a unique architecture called "workchain," which differs from traditional blockchains. Unlike Ethereum's sub-addresses or Bitcoin's hierarchical deterministic wallets, TON does not natively provide specific sub-address concepts.

To integrate TON tokens, you need to manually add and configure addresses within the project. For detailed steps, please refer to here.

The shard recovery feature is designed for multisig wallets, allowing shard restoration when a creator loses their shard. The recovery process requires all wallet creators to participate online by importing their recovery phrases. Upon successful recovery, all creators' shards will be reset.

Important notes for shard recovery:

• Wallets that don't support TON/SUI chains: Only have one set of recovery phrases, can perform reset and recovery functions.

• Wallets that support TON/SUI chains: Need to use a device that has the wallet's shards to perform the reset operation. During reset, two sets of recovery phrases will be generated for you, and you can use the recovery function normally afterward.

• New users creating wallets will directly get two sets of recovery phrases and can use the reset and shard recovery functions normally.

Recovery Manual:

Enter the wallet information page through the following entry.

Click "Recover" under Shard Management.

After clicking, a recovery shard window will appear, then you need to wait for other members to come online. Note: Other members need to switch their page to the current team to be recognized as online.

When all members have agreed to join, the initiator can click "Start".

Invited members can view the invitation in their wallet notifications.

After starting, you need to enter recovery phrases. New users creating multisig wallets will have two sets of recovery phrases and need to enter the first set of secp256k1 recovery phrases. If it's an old user's wallet that doesn't support TON/SUI chains, the system will automatically determine, and the user only needs to enter one set of recovery phrases to recover.

After completing the first set, you can then enter the second set of ed25519 recovery phrases. If it's an old user's wallet that doesn't support TON/SUI chains, the system will skip this step directly.

You need to wait for all members to import their recovery phrases. After all members have finished importing, the initiator clicks "Start".

If each member entered the correct recovery phrases, the shards will be successfully recovered immediately after the recovery animation finishes, and all members' shards will be reset. Note: After recovering shards, previously authorized shards on other devices will also become invalid and need to be reauthorized.

Cregis features an address book, similar to a contact list, allowing users to save recipient addresses, making future payments quicker without re-entering details. Additionally, users can enable address verification, ensuring that only saved addresses can be used for outgoing transfers, preventing potential losses from incorrect entries.

You can navigate to address book under "Manage" section.

Add an Address

You can add an address by clicking "+", then choose the token and enter address and alias.

Delete an Address

This record will not be stored in the system, so please remember to copy the signature information for future reference.

Cregis offers a standardized API that allows enterprises to seamlessly integrate our wallet into their applications, ensuring a smooth user experience and efficient operations. With Wallet as a Service (WaaS), businesses can provide digital wallet services without the need to build or maintain their own wallet infrastructure, simplifying implementation and reducing development costs.

1. Generate address

• Through the API, enterprises can generate sub-addresses which belong to the main address owned by the enterprises.

• These sub-addresses could be generated to their users for crypto payment receive.

• Cregis provides a "collection" function for the enterprise to collect all sub-address assets to the specified wallet address, which is convenient for user management and use. The successfully collected funds and miner fees can be queried in the transaction records of the wallet.

2. Crypto Withdrawal or Payment (WaaS)

• For corporate transfers or withdrawals, it is required to operate from the Cregis enterprise wallet.

• To ensure request security, it is necessary to request the IP address of the Cregis API server and add it to the IP whitelist. The Cregis API only grants access to IP addresses in the whitelist.

3. Crypto Payment Gateway

This API requires an application. If you're interested, please .

• Cregis provides API for enterprises to integrate a crypto payment gateway into their online store or physical point-of-sale (POS) systems. Consumers can check out by selecting cryptocurrencies as the payment method.

• Cregis will collect payments on behalf of merchants and return to the merchants during settlement.

• Cregis also provides automatic currency exchange according to the needs of enterprises. For example, we can convert cryptocurrencies into fiat currency and disburse them to merchants

• Cregis can design a payment page for enterprises. After receiving the payment details, Cregis transforms the content into a visual page that can include the enterprises' logo and is displayed to the user.

Solana transactions may fail due to network congestion or insufficient gas fees. Since the Solana blockchain does not provide a rollback mechanism for failed transactions, transactions must be manually resent. Please note that the funds and gas fees from the original transaction will remain frozen. To resend a transaction, ensure your account has sufficient balance. For assistance, please contact us at [email protected].

Steps to Resend a Transaction:

1. If a Solana transaction remains in a "pending confirmation" state for over 5 minutes, the system will display a "Resend" button.
2. Click the button to enter the resend interface, where transaction details, including the gas fee, will be displayed. Click "Confirm" to proceed. Note: Funds from the original transaction are frozen, and insufficient account balance will prevent further action.
3. Complete identity verification after clicking "Confirm."
4. Once the transaction is successfully resent, a notification will appear. After the transaction is completed, the funds from the previous transaction will be unfrozen, and the gas fee will not be deducted.

Digital asset wallets are generally divided into two types: custodial wallets and non-custodial wallets. To understand the difference, it’s important to first understand how crypto wallets work. Crypto wallets do not actually store a user’s funds. Instead, they store public and private keys. The public key enables users to set up transactions, while the private key authorizes them.

Custodial Wallets vs. Non-Custodial Wallets

• Custodial Wallets In a custodial wallet, a third party manages the private keys on behalf of the user. This means the third party has full control over the digital assets and is responsible for managing wallet keys, signing transactions, and protecting the user's assets.

• Non-Custodial Wallets A non-custodial wallet gives full responsibility for managing digital assets to the owner. Users have complete control over their digital assets, manage their private keys, and handle transactions independently. Non-custodial wallets usually provide users with a recovery phrase. This phrase can generate the public and private keys and acts as a backup or recovery mechanism. However, anyone with access to the recovery phrase can fully control the assets in the wallet.

Advantages of Non-Custodial Wallets

1. Complete Ownership and Control Users retain full control of their digital assets, ensuring that no third party or individual can interfere.

2. Offline Key Storage Private keys or recovery phrases can be stored offline, providing secure asset ownership and safety in physical environments.

3. Direct Blockchain Transactions All transactions occur directly on the blockchain without involving intermediaries, ensuring security and authenticity.

Challenges of Non-Custodial Wallets and Cregis’ Solutions

Challenge 1: Managing Recovery Phrases and Private Keys

Users must safeguard their recovery phrases and private keys. If lost or stolen, users may lose access to their assets permanently.

Cregis’ Solution: Through MPC (Multi-Party Computation) technology, Cregis eliminates the need for users to handle raw private keys or recovery phrases during daily operations. This innovative approach combines MPC with recovery phrases, ensuring users retain full control of their assets while removing the risks associated with private key exposure. Even if the recovery phrase is lost, users can securely transfer assets to another device using MPC shard technology without relying on the original private key.

Challenge 2: Complex User Interaction

Traditional non-custodial wallets often have a steep learning curve, making interactions cumbersome for users.

Cregis’ Solution: Cregis streamlines the user experience with a user-friendly and intuitive interface, simplifying interactions and eliminating complexities, allowing users to manage their assets efficiently and securely.

By combining the strengths of non-custodial wallets with advanced MPC technology and threshold signature schemes, Cregis provides a highly secure, efficient, and user-friendly solution for digital asset management.

On September 4, 2024, Polygon officially upgraded its native token MATIC to POL. This upgrade aims to support a broader ecosystem development and meet the needs of decentralized networks. For MATIC holders, no action is required. Cregis has automatically converted your MATIC to POL at a 1:1 ratio.

Other wallets achieve separate signing by storing one party’s shard on the cloud after their signature is completed, then waiting for the other party to sign. However, this approach temporarily grants the platform full access to the private key, introducing significant security risks. To protect user assets, Cregis adopts a more rigorous security design to avoid such vulnerabilities.

Cregis' multi-signature functionality is built on MPC (Multi-Party Computation) technology, ensuring that a user's private key never exists in its complete form. During the signing process, shards from all parties interact in real-time through encrypted protocols to complete the signature, eliminating the need for any shard to be stored in the cloud. This guarantees absolute security for the private key while removing the potential risks associated with centralized storage.

Furthermore, Cregis now offers an automatic signing feature. Users can set specific signing conditions (e.g., automatic signing for transactions below 1,000 USD). Once enabled, the system can automatically complete signatures based on the predefined criteria, provided the Cregis remains open. This removes the need for all parties to be online simultaneously, significantly improving convenience and efficiency while maintaining Cregis' high-security standards.

In certain blockchains (e.g., TRON or Solana), activation fees are required due to their design mechanisms and resource management strategies. Generally, new addresses without transactions do not incur activation fees. Activation fees are typically charged when an address first receives a transfer or performs a specific operation.

Here are the main reasons for activation fees:

Ensuring Address Validity

• Address Initialization: Some blockchain systems require addresses to be initialized before use. Activation fees cover the minimum state storage needed to create an address, ensuring its functionality.

• Preventing Junk Addresses: Requiring activation fees discourages the creation of large numbers of unused or invalid addresses, reducing unnecessary blockchain storage usage.

Paying for On-Chain Resources

• Storage Resources: Every address on the blockchain occupies some storage space. Activation fees compensate node operators for storing and maintaining this data.

• Bandwidth and Computational Resources: Some blockchains use activation fees to allocate computational resources and bandwidth, such as energy and bandwidth on TRON, which are crucial for executing transactions.

Preventing Malicious Activities

• Abuse Prevention: Activation fees increase the cost of generating large volumes of unused addresses, reducing the risk of spam attacks (e.g., DoS attacks).

• Protecting Network Stability: By limiting the speed of address creation, activation fees reduce excessive consumption of node and network resources, ensuring blockchain stability.

Incentive Mechanism

• Resource Allocation: Activation fees are often distributed to miners or node operators as compensation for blockchain operational costs, providing financial incentives for network maintenance.

• Cregis utilizes AnyChain, the world's first open-source multi-chain transaction construction library entirely written in Rust language.

• Here are the Protocols and the tokens we support.

In terms of wallet permission management, Cregis has separated it from the overall team account permissions. Team administrators can only grant members the ability to create wallets. To modify permissions for individual wallets, you need to go to the wallet management page itself.

Wallet Authority

In addition to subscribing to a team plan, Cregis also offers individual feature purchases. Below are the available features and activation steps:

1. Add Team Members

Adding more team members enhances collaboration within your organization, allowing various roles and departments to manage crypto assets in a secure and coordinated environment. This feature improves teamwork and operational efficiency.

This feature is only available for upgraded team plans.

Go to the Team Account page and locate your subscription details. Click "Expansion".

Transfer a Payment

1. Select the wallet for the transfer and click the "Send" button. Sending here can be done even without shard, as long as you have the sending permissions for the wallet to initiate a transaction.

Why Does BTC Have Different Address Formats?

The variety of Bitcoin address formats stems from ongoing technical upgrades aimed at overcoming early network limitations, such as transaction speed, fees, and scalability. Innovations like SegWit were introduced to improve transaction efficiency and security while supporting additional features. At the same time, compatibility with older address formats was maintained. The evolution of address formats reflects Bitcoin’s continuous adaptation and optimization to meet changing user needs.Common BTC Address Formats and Their Uses

In daily operation, if the business callback fails due to abnormal factors such as changes in the callback address of the business platform and unstable network, and the order status is not updated, it can be viewed and processed in the project callback record.

1. Click "API" in the Cregis client - > "History Callback" to display abnormal callback records by default. If the data is empty, it means that there is no abnormal callback data in the current project.
2. If there is an abnormal callback that causes the order status of the business platform to not be timely updated, click the "Feed" button.

When a transaction cannot be completed due to low gas fees, users can use the speed-up or cancellation feature. Please note this feature is only available for BTC and ETH-based cryptocurrencies.

ETH Series

Transaction Speed Up

Click "Speed Up" in the pending transaction.

Once clicked, transaction details will expand with an option to increase the gas fee. Users can choose from different gas fee options or customize the fee.

Custom gas fee settings are divided into Advanced Mode and Standard Mode:

• Advanced Mode: Uses the EIP-1559 protocol, which applies a new fee calculation method to accelerate transaction confirmation. This mode theoretically reduces gas fees compared to Standard Mode. In Advanced Mode, users can customize the Max Fee and Max Priority Fee, allowing precise control to ensure transaction priority. This mode is particularly suitable for users who need high-priority confirmation while aiming to save on fees.

• Standard Mode: Based on the traditional gas fee structure, users can set the Gas Price and Gas Limit to determine the transaction fee. Although this mode is gradually being replaced by the EIP-1559 protocol, it remains suitable for users who are unfamiliar with the new mode or prefer traditional fee settings.

Once the setup is complete, proceed with identity verification.

After verification is completed, a "Speeding Up" tag will appear. Once the acceleration is complete, a "Speed up" tag will be displayed.

Transaction Cancellation

In the pending transaction, click "Cancel."

Clicking will expand the transaction details, displaying an option to set the gas fee for cancellation. Users can choose from various gas fee options or customize the fee.

Since transaction cancellation involves resending a transaction with an amount of $0, the amount is displayed as 0.

After completing the setup, proceed with identity verification.

Upon successful cancellation, the user interface will display two transaction records: one with an amount of $0, representing the cancellation request, and the earlier record will show a "Cancelled" tag.

BTC Series

Transaction Speed Up

Click "Speed Up" in the pending transaction.

Once clicked, transaction details will expand with an option to increase the gas fee. Users can choose from different gas fee options or customize the fee.

CUsers can set the Gas Price and Gas Limit when customizing the gas fee. The system will automatically estimate the gas fee as a reference.

After completing the setup, click "Confirm" and proceed with identity verification.

Once verification is successful, a "Speeding Up" tag will appear. If the waiting time is too long, users can choose to accelerate again by adjusting the gas fee.

After the acceleration is complete, an "Speed up" tag will be displayed.

Transaction Cancellation

In the pending transaction, click "Cancel".

Clicking will expand the transaction details, showing an option to set the gas fee for cancellation. Users can choose from various gas fee options or customize the fee.

For BTC cancellations, the Replace-by-Fee (RBF) method is used, which sends a new transaction with the same UTXO as the original. As a result, the transaction amount is displayed as $0.

After completing the setup, proceed with identity verification.

Upon successful cancellation, the user interface will display two transaction records: one with an amount of $0, representing the cancellation request, and the earlier record will show a "Cancelled" tag.

Resetting shards will invalidate all previous shards, and only the device used for reset will generate new shards. The reset process requires participation from all wallet creators, and the number of shards must meet the signature threshold.

Multisig wallets will generate new recovery phrases after reset.

Single-signature wallets will continue using the original recovery phrases.

Single-signature wallet

Click the upper-right corner to enter the Wallet Info page.

Select the Reset function under Shard Management.

Enter the wallet's recovery phrase to reset shards.

After entering the correct phrase, an identity verification window will appear. Complete verification to finalize the shard reset.

Multisig Wallet

Resetting a multisig wallet generates new recovery phrases, with variations depending on wallet type:

• Legacy wallets (non-TON/SUI support):

  Single recovery phrase set; reset regenerates one set.

• TON/SUI-compatible wallets:

  Requires a device with existing shards for reset.

  Generates two new recovery phrase sets for future recovery use.

• Newly created wallets (default two phrase sets):

  Reset produces two fresh recovery phrase sets.

Note: Both old and new recovery phrases remain valid for wallet access and asset management. Store all phrases securely.

Enter the Wallet Info page via the upper-right menu.

Click Reset.

A reset window appears— you need to wait for other members to come online. Note: Other members need to switch their page to the current team to be recognized as online.

After identity verification, the initiator sends invitations.

Invited members can view the invitation in their wallet notifications.

Since the shard reset operation has requirements for the number of shards, the page will simultaneously display whether each joining member's device contains shards. The reset can begin once all required members have joined and sufficient shards are available.

The process starts with a shard reset animation, followed by a risk warning that requires confirmation.

After completion, there will be a risk warning that needs to be acknowledged.

The system will then generate new recovery phrases according to your wallet type and proceed with backup and verification.

• Wallets that don't support TON/SUI chains: only regenerate one set of recovery phrases.

• For wallets that support TON/SUI chains: the reset will generate two sets of recovery phrases.

• Newly created wallets already come with two sets of recovery phrases by default: resetting will generate two new sets of recovery phrases.

This is the display for the second set of recovery phrases.

After completing verification, wait for other members to finish their backups. After all creators successfully complete their backups, the shard reset will be finished.

What is a Policy Engine?

The Policy Engine is a comprehensive risk management tool in Cregis, offering flexible solutions for withdrawal management. It allows users to set detailed rules and automate actions to regulate withdrawal requests from team members, with future plans to support automatic signing and withdrawals for improved efficiency and reduced manual risks. Currently, it supports policy customization for transaction, payment request initiation, and API withdrawals, enabling users to tailor policies to their needs, such as limiting withdrawals to specific tokens or setting time restrictions. The Policy Engine also includes a daily log feature for monitoring and reviewing policy execution, ensuring transparency, tracking, and auditing of all actions to enhance risk management and safeguard assets.

What is Auto-Collection/ Signing?

This automated feature allows users to perform automatic fund collection and transaction signing based on preset rules, eliminating the need for manual monitoring by the enterprise. Once the rules are set, the system can operate 24/7 according to the configured rules, significantly reducing manual intervention. For example, while enterprises previously had to manually collect funds daily, with this automated feature, users can set intervals for automatic fund collection. Additionally, collection can be triggered when a specific cryptocurrency reaches a certain amount. Currently, the auto-signing feature is limited to API withdrawals and is only available for single-signature wallets. Furthermore, all these automated functions are performed locally, requiring no custodial sharding actions. Users only need to stay online to execute them, ensuring system security while greatly improving operational efficiency for businesses requiring frequent transactions.

Pricing and Activation Process

• Currently, the automated feature is only available to monthly subscription users and requires an additional payment of USD $500 per month. To activate, go to the account interface below and click "Activate."

• After clicking, a window will pop up where users can select the desired number of months and press "Submit."

• After submitting the order, you can proceed with payment immediately. Once the payment is successful, the feature will be activated.

User Manual

Before proceeding, please ensure that the automation feature has been activated.

1. Navigate to the automated feature page and click "Create Rule."

2. Create an Auto-collection Rule

After clicking "Create Rule," a sidebar will pop up to begin configuration.

Basic Settings

When creating a rule, first set the name and type. After selecting the "Auto-collection" type, a section will pop up requiring the selection of the collection type and WaaS project.

Collection types include System Collection and API Collection. System Collection automatically collects funds from sub-addresses that meet the rules you set. API Collection processes collection requests initiated via API based on the rules you configure.

Trigger Conditions

Trigger rules require setting the cryptocurrency, collection time, and receiving address conditions.

• Cryptocurrency Each rule can only define one type of cryptocurrency. When adding, the system will display the available cryptocurrencies pre-configured in the wallet of the selected API project. Once the cryptocurrency is selected, you must set the amount that will trigger Auto-Collection. You can specify both "greater than" and "less than" conditions. For example, to trigger collection between $100 and $200, set "greater than or equal to 100" and "less than or equal to 200." Please note, if the conditions are not logically valid, the rule cannot be created. For example, setting "less than or equal to 50" and "greater than or equal to 51" will not be allowed.
• Execution Actions Users can choose to execute Auto-Collection either at regular intervals or at a specific time each day. The time is currently based on UTC+8.

• After completion, click "Submit." Identity verification is required after submission. The rule is created once verification is successful.
• After creation, the rule must be enabled to take effect. Enabling requires the current device to have the wallet shard imported and password and Google two-factor authentication. The feature starts officially after successful verification.
• After successful collection, go to the project address page, where "Auto-collection" will be displayed. Note: The client must remain online during auto-collection; otherwise, the process will be interrupted.

3. Create an Auto-Signing Rule

After clicking "Create Rule," a sidebar will pop up to begin configuration.

Basic Settings

When creating a rule, first set the name and type. After selecting the "Auto Signing" type, a section will pop up requiring the selection of the withdrawal type and withdrawal wallet. Please note that only single-signature wallets are supported, and the default payment address will be used for signing and withdrawals.

Trigger Conditions

The trigger conditions require setting cryptocurrency, withdrawal type, and execution action.

• Cryptocurrency

Only one cryptocurrency can be set per rule. When adding, the system will display the currencies already set in the selected withdrawal wallet. After setting the currency, specify the amount that triggers auto-signing. Both "greater than" and "less than" conditions can be set simultaneously. For example, to set $100–$200, set "greater than or equal to 100" and "less than or equal to 200."

Please note, if the conditions are illogical, the rule cannot be created. For example, setting "less than or equal to 50" and "greater than or equal to 51" will be rejected.

• Withdrawal Type Since only API withdrawals are currently supported, this section requires selecting the API for withdrawals.

• Execution Actions Scheduled signing can be configured here. The time is currently based on UTC+8. Additionally, users need to set the interval (in minutes) for signing. If multiple transactions are triggered, they will be bundled on-chain, which may save gas fees on certain chains.

• After completion, click "Submit." Identity verification is required after submission. The rule is created once verification is successful.

• After creating the rule, you must enable it for it to take effect. During activation, you will need to enter your password and complete Google two-factor authentication (2FA). Once verification is successful, the rule will be officially active and ready for use.

• After you enable the rule, you can go to Team activity page, where the status will display "Operating Auto Sign" Please note that you must remain online during the Auto-Signing process; otherwise, it will be interrupted.

4. Edit and Delete Automation Rules

• Edit Rules

Established rules can be edited in the rule configuration page. Before editing, you must first disable the rule, and identity verification is required when disabling the rule.

• Delete Rules Established rules can be deleted from the rule configuration page. Before deleting, the rule must first be disabled, and identity verification will be required during the disabling process.

5. View Automation Logs

In the execution logs, you can track the activity of each rule, including the date, time, operator, and action taken.

On this page, users can also filter the logs by operation date, operator, or log type.

The search bar also supports searching for related records using the rule name or ID.

6. Triggering Auto-Collection

When the conditions of an Auto-Collection rule are met, the system will automatically execute the collection. Users can check the details of the Auto-Collection on the project address page.

• The details will show the runtime, start time, number of collections, and total amount collected. Additionally, the transaction history will list each collection.

• If there are insufficient gas fees, the Auto-Collection will pause, and a prompt will appear notifying the user to top up. The user can directly click "Recharge" on this screen and recharge using the provided address or QR code. After recharging, the system will resume the action at the next trigger point.

7. Triggering Auto-Signing

• When the conditions for an auto-signing rule are met, the system will automatically perform the signing. Users can view the signing details in the collaboration section, and an "Auto-Signing in Progress" icon will appear in the lower-right corner.

• The details will show the runtime, start time, the number of signed transactions, total amount, and the gas fees used for signing. The transaction history will also list each signed transaction. If there are insufficient gas fees, the auto-signing process will be paused, and a prompt will notify you to top up. You can top up directly from this screen by clicking "Top Up," and using the address and QR code provided. Once the top-up is complete, the action will resume at the next trigger point.

Real-World Scenarios

The actual setup should be tailored to the user's specific needs. Below are examples of how Auto-Collection/Auto-Signing can be configured in various scenarios:

Scenario 1: I want to collect USDT from the project's sub-addresses on a daily basis.

In this case, as long as there is USDT in the project's addresses, it will trigger the Auto-Collection rule. The user only needs to set the cryptocurrency (USDT) and customize the daily collection time, such as at 12:00 PM each day.

Scenario 2: Automatically sign withdrawals under USDT $100 on weekends.

In this case, you need to set cryptocurrency (USDT), the specific days for auto-signing (weekends), and the interval between each signing. For example, you can specify that the system checks every 30 minutes on Saturdays and Sundays for any withdrawals under $100 and signs them automatically.

Cregis Payment Engine offers a one-stop cryptocurrency payment solution for businesses. Merchants can quickly integrate the system through a simple API. We provide a pre-designed checkout page for immediate use, while also allowing merchants to customize their own interface based on specific needs. When a merchant initiates a payment request, the system generates a unique payment address, and funds are deposited into the Cregis wallet. Through a 10-minute automatic settlement mechanism, funds are swiftly transferred to the merchant's designated wallet. Merchants can use the Cregis desktop application to view order status, settlement data, and other transaction details at any time, making payment management effortless. We support multi-chain and multi-currency payments, ensuring efficient and flexible fund transfers, and delivering a secure and convenient cryptocurrency payment experience for our clients.

Payment Rules

Cregis supports multiple currencies and chains as order currencies, payment currencies and settlement currencies including fiat currencies and cryptocurrencies. If the order currency differs from the payment currency, Cregis will obtain the latest exchange rate in real time and convert and lock the exchange rate for the entire order validity period.

Settlement Rules

• Regular Settlement: If the pending settlement amount reaches or exceeds the equivalent of 50 USDT (testing phase) / 500 USDT (live phase), settlement will occur every 10 minutes.

• Minimum Threshold Settlement: If the accumulated pending settlement amount remains below the equivalent of 50 USDT (testing phase) / 500 USDT (live phase), a Minimum Threshold Settlement will be triggered. This ensures merchants receive a payout at least once every 24 hours. To facilitate testing for newly onboarded merchants, the first transaction under 50 USDT will automatically trigger this settlement within 10 minutes.

• Settlement Amount: The amount will be credited after deducting transaction fees.

If fiat settlement is required, please for inquiries.
