I am using a web3 sendTransaction function to send coins, and then storing the transactionHash in my databse

await web3SendInstance.eth.sendTransaction({to:receiveAddress, from:web3.eth.defaultAccount, value:amount, chainId:chainid, gas:21000, gasPrice:currentGasPrice, txHash:txHash,})
            .on('transactionHash', function(hash){
          
               saveTxHash(hash);

            })

The problem is that sometimes these transactions get dropped and never mined, and so the hash that is returned is irrelevant.

How do I check that the txhash doesn't get dropped, and why is it sometimes dropped?

  • What was the error? be clear please there too many reasons a transaction (sendTransaction) has an error. Also what is txHash? Have you tried to use only: from, to, and value parameters.

  • I didn't say it threw an error, I said that the transaction hash becomes irrelevant. There are no errors, I get returned a hash from the .on() function but that hash sometimes isn't a hash that links to any transaction on etherscan Sep 22 at 11:21

I didn't see any issue here, I removed the txHash:txHash,. Interesting was your transaction on testnet or mainnet?
