I see you are having trouble retrieving transaction data on the Ethereum blockchain.

Problem retrieving Ethereum transactions: Unable to retrieve TX/RTX methods

While you are running Bitcoin-D, which is downloading previous blocks, and are trying to retrieve transaction information from another shell, I will walk you through the steps to resolve this issue. Please note that Ethereum has undergone significant changes since Bitcoin-D was last updated, so it is possible that this issue has been resolved in a newer version.

Problem Symptoms

When you try to use the gettransaction or getrawtransaction methods in a shell, you will see an error message that says:

Unable to get tx using method 'gettransaction' or 'getrawtransaction'

This is probably because the Ethereum blockchain has not yet been synced, causing attempts to fetch the transaction data to fail.

Solutions

Try the following steps to resolve this issue:

• Wait for the blockchain to sync: Make sure your system has reached a stable blockchain snapshot by running bitcoind --syncmode full in a shell (e.g. bitcoin-d) before attempting to fetch transaction data in another shell (e.g. another-shell). This will help sync the blockchain.

• Update Bitcoin-D or use a different version: If you are using an older version of Bitcoin-D, you should consider updating to a newer version that supports retrieving Ethereum transactions. You can check for updates by running bitcoind --version in a shell and following the instructions to update 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 synchronized before attempting to retrieve them.

Code example (Bitcoin-D 0.20.1)

Here is an example of how to update and fix the problem:

Update Bitcoin-D to version 0.21.2 or higher
bitcoind --update=1 --version

Wait for the blockchain to sync
bitcoin-d --syncmode full --txindex true

Retrieve the transaction data
gettransaction tx_hash

Replace tx_hash with the actual hash of the transaction you want to retrieve.

Additional notes

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

• If you are 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).

Following these steps should resolve the issue of not being able to retrieve transaction data using the gettransaction or getrawtransaction methods. If you are still having issues, please feel free to provide us with more details about your environment and Bitcoin-D version for further assistance.
