Ethereum is a public blockchain platform that enables developers to build decentralized applications (dApps). If you’re experiencing issues with sending transactions, I can provide general guidance on how to troubleshoot the issue.

Troubleshooting Ethereum Transaction Issues

1. Verify Transaction Signature

If you’re unable to send a transaction via sendrawtransaction in your console of Bitcoind, ensure that:

• The transaction signature is valid.

• The public key used for signing matches the one provided by the sender.

Try sending a new transaction with the same sender and recipient addresses. If the issue persists, proceed to the next step.

2. Verify Script Signature

Ethereum uses a script verification process to validate transactions. A mandatory-script-verify-flag-failed error occurs when the scriptVerify flag is not set or is set incorrectly during transaction signing.

Try adding the following flags to your --script-verify argument:

--script-verify --scriptsverify= true --scriptverify= true  
for mainnet, testnet or development network

Replace with the actual script that you’re trying to verify. If the error persists after setting the scriptVerify flag, proceed to the next step.

3. Check Block Height

If your transaction is failing due to a block height issue, ensure that:

• The block height matches the current block height.

• The block height is not too high or too low compared to the sender’s balance.

You can use getblockcount and getblock commands to verify the current block height:

getblockcount

Current block count: 123456789



getblock

Current block hash: abcdefghijklmnopqrstuvwxyz123456789

4. Verify Transaction Source

If you’re using a multisignature wallet or have multiple addresses, verify that the transaction source matches the expected address.

Try sending the same transaction to different addresses to confirm the issue is specific to one address.

5. Check Network Connection

Ensure that your network connection is stable and working correctly. A slow or unstable internet connection can cause issues with transaction validation.

If none of these steps resolve the issue, you may want to consider seeking further assistance from Ethereum developers or a local community forum.
