I see you’re experiencing issues with retrieving transaction data on the Ethereum blockchain.

Ethereum Transaction Retrieval Issue: Can’t Get TX/RTX Methods

As you’re running Bitcoin-D, which is downloading previous blocks, and attempting to retrieve transaction information from another shell, I’ll guide you through the steps to resolve this issue. Please note that Ethereum has undergone significant changes since the last update of Bitcoin-D, so it’s possible that this issue has been fixed in a recent version.

Issue Symptoms

When trying to use gettransaction or getrawtransaction methods in one shell, you’ll encounter an error message stating:

Cannot get tx with 'gettransaction' or 'getrawtransaction' method

This is likely due to the Ethereum blockchain not being synced yet, causing the transaction data retrieval attempts to fail.

Solutions

Try the following steps to resolve this issue:

• Wait for the block chain to sync: Ensure that your system has reached a stable blockchain snapshot by running bitcoind --syncmode full in one shell (e.g., bitcoin-d) before attempting transaction data retrieval in another shell (e.g., another-shell). This will help synchronize the blockchain.

• Update Bitcoin-D or use a different version: If you’re using an older version of Bitcoin-D, consider updating to a more recent version that supports Ethereum transaction retrieval. You can check for updates by running bitcoind --version in one shell and following the instructions for updating your version.

• Use the --txindex flag: In some cases, you may need to use the --txindex flag when calling gettransaction or getrawtransaction. This flag tells Bitcoin-D to wait until all transactions have been synced before attempting to retrieve them.

Sample Code (Bitcoin-D 0.20.1)

Here’s an example of how to update and fix the issue:

Update Bitcoin-D to version 0.21.2 or later

bitcoind --update=1 --version



Wait for the blockchain to sync

bitcoin-d --syncmode full --txindex true



Retrieve transaction data

gettransaction tx_hash

Replace tx_hash with the actual hash of the transaction you’re interested in retrieving.

Additional Notes

• Make sure that your system has a stable internet connection and sufficient bandwidth to download all transactions.

• If you’re experiencing persistent issues, consider restarting your Bitcoin-D process or updating your entire network stack (e.g., apt-get update && apt-get upgrade on Linux distributions).

By following these steps, you should be able to resolve the issue of unable to retrieve transaction data using gettransaction or getrawtransaction methods. If you continue experiencing difficulties, feel free to provide more details about your environment and Bitcoin-D version for further assistance.
