Ethereum transactions can be cancelled in a pending state. 1) Use MetaMask and other stored cancellation functions: find the transaction in the "Activities" section, select "Cancel", and confirm the cancellation through a new transaction with high gas fees. 2) Cancel with custom nonce: Advanced users can find the nonce value of the stuck transaction through the blockchain browser, and then send a new transaction with the same nonce but high gas fees to replace the original transaction.

Ethereum transaction cancellation method

If you want to cancel an Ethereum transaction, the premise is that the transaction is in a pending state and once the transaction is confirmed on the Ethereum blockchain, it cannot be cancelled. Here are some common ways to cancel:
  • Use stored in-app features (taking MetaMask as an example)
    • Open MetaMask Save and find the pending transaction in the Activity section.
    • Select the Cancel option.
    • Confirm the cancellation by signing a new deal with higher gas fees. This method sends an alternative transaction with the same random number as the pending transaction but without any value or data, effectively overwriting the original transaction.
  • Cancel transactions with a custom nonce (for advanced users or storage cancel option is not available)
    • Find the random number of stuck transactions: Use the blockchain browser to search for your storage address, find the stuck transactions and record its random number value.
    • Send replacement transactions: Turn on your save and enable the Custom Random Numbers feature in settings; create a new transaction to your own storage address, set the same random number as the pending transaction; set the gas fee higher than the original transaction to ensure priority. Once submitted, a new transaction will replace the pending transaction.

    • Order trading : There are two common ways to place orders, namely limit orders and market orders. A limit order is where you can specify a price, and the order will be executed only when the market price reaches or is better than the price you specify; a market order is to execute the transaction immediately at the current market price. Based on your judgment of the market and trading strategy, select the appropriate order method, enter relevant information such as transaction quantity, and submit the order after confirming that it is correct.

If you want to continue trading on the trading platform, you can leave Ether in the platform's storage, but pay attention to the security and relevant policies of the platform.
