[Ethereum] How to create a transaction with same nonce

nonce

How do I create a new transaction that has the same nonce as a previous transaction?

I sent a txn with 4Gwei gas price and I want to cancel it by sending a 0 Eth txn with the same nonce.

I am running geth 1.7.1.

Simply pass nonce parameter to sendtransaction. Suppose the transaction you want to cancel has nonce 13. Then try sending a transaction from same account with same nonce.

eth.sendtransaction({from:fromAccount,to:fromAccount, value:web3.toWei(0,"ether") nonce: 13, gasPrice:10000000000})

Note that you need to send the gas price higher than you sent previously. Make it around 10GWei.

You're correct that all subsequent transactions would be refused.

So with Geth, you can rebroadcast with a higher fee (gas price) by using eth.resend (the nonce will remain the same).

eth.resend(tx, optional gas price, optional gas limit)

Example:

eth.sendTransaction({from: eth.accounts[0], to: "...", gasPrice: "1000"})
var tx = eth.pendingTransactions[0]
eth.resend(tx, web3.toWei(20, "GWei"))
