Cancel

A transaction can be canceled by the same EOA that initiated the same transaction. If a user feels that they have initiated a wrong transaction accidentally, they can cancel that transaction by initiating another transaction having the same nonce and changing the To fields to their own EOA address. This new transaction must have a higher gas price. A higher gas price is set to ensure that the new transaction will be given priority over the older transaction and can cancel the transaction as soon as possible. This type of transaction is called a self transaction.
