Ethereum Full Node: TXINDEX=1 Configuration Issue
I am writing this article as a troubleshooting guide for Ethereum full node users who are having issues with transaction indexing and wallet transactions not being found.
The Problem:
When using a full node, transactions are indexed to ensure that every block is verified before it can be mined. In your case, the issue is with the « txindex » parameter in the full node configuration file (« ethereum.conf »). Specifically, when set to « 1 », it disables transaction indexing across the entire Ethereum network.
Symptoms:
- Transactions associated with my wallet are not found by the full node.
- Only transactions from blockchain.info (or other external sources) will be indexed and included in the wallet’s transaction history.
Why TXINDEX=1?
TXINDEX=1 is a common configuration setting for Ethereum full nodes. However, it appears that this setting was not enabled on the full node or may have been misconfigured.
Solutions:
- Check your node’s full configuration file: Be sure to review and verify the
ethereum.conffile to make sure that TXINDEX=1 is indeed set to `1. You can try searching for similar issues online or contact the Ethereum community forums for help.
- Update your HD source code: If you have updated your Ethereum HD source code, double-check that it is still in sync with the blockchain. Make sure the new core is compatible with your current block height and network configuration.
- Temporarily disable TXINDEX=1: Try disabling TXINDEX=1 to see if that resolves the issue. This can help determine if the issue is specific to this setting or if there are other underlying issues.
- Check for conflicts with other full nodes: If you are using multiple Ethereum full nodes, make sure they are all running on the same blockchain and configuration settings.
Conclusion:
If none of the above solutions resolve the issue, please provide more details about your setup, including:
- Full version and node architecture
- Blockchain software (e.g. Parity or Hyperledger Fabric)
- Wallet software used to handle transactions
I would be happy to help troubleshoot this issue with more information.
