The trick to "cancel" a pending Ethereum transaction is to replace it by another one with the same Nonce and higher gas fees
​
​
NB: You can send a 0 ETH value to your own address
​
​
Note :
A nonce is a variable that increments by 1 at each outgoing transaction made and therefore represents the total number of transactions made with a specific address
On the Etherscan blockchain browser, you can view the nonce of a transaction (TX) by clicking 'Click to see More'
. The first value corresponds to the Transaction Nonce
. The second value corresponds to the Index position of the Transaction in the block
