Transaction Speed Up and Cancellation

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.

After clicking, if the token has more than one pending transaction, a transaction speed-up list page will pop up. Operate in order from the smallest Nonce to the largest by clicking "Speed Up." If the token has only one pending transaction, skip this step.

Clicking "Speed Up" will expand the transaction details and provide options for the speed-up gas fee. Click to choose from different gas fee options. Users can also customize the gas 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 authentication is complete, you will see a "Speeding Up" tag.

After the speed-up is complete, you will see an "Sped Up" tag.

Transaction Cancellation

Click "Cancel" within a pending transaction.
