Ethereum: Safe-cli issue with Trezor

Ethereum: Safe-CLI Issue with Trezor Wallet

As a developer of Ethereum-based applications, you’ve likely encountered issues with using the Trezor wallet for secure transactions. One common problem is encountering errors when trying to send transactions via the safe-cli, a popular command-line interface (CLI) tool for interacting with the Ethereum network.

In this article, we’ll delve into the issue and explore potential solutions to resolve it.

The Issue:

When using the Trezor wallet with the safe-cli, you may encounter an error similar to:

Error sending transaction:

  Address mismatch

  Error validating signature

This error occurs when the Trezor wallet doesn’t recognize the address you provided or fails to validate the signature of your transaction.

Causes of the Issue:

There are several reasons why this issue might occur, including:

• Address format:

  The Trezor address may be formatted incorrectly or contain non-ASCII characters.

• Private key mismatch: The private key associated with the Trezor wallet may not match the private key expected by the safe-cli.

• Trezor version incompatibility: The Trezor wallet and the safe-cli versions might not be compatible, leading to errors during transaction execution.

Solutions:

To resolve this issue, follow these steps:

1. Verify Address Format

Ensure that your address is formatted correctly using the load_trezor_cli_owners command with the following options:

load_trezor_cli_owners --addresses  --output 

Replace with the Trezor wallet address, and with a file where you want to save the output.

Example:

load_trezor_cli_owners --addresses 0x1234567890abcdef --output trezor_output.txt

2. Check Private Key Mismatch

Verify that your private key matches the expected one for the Trezor wallet using the following command:

trezor-cli -p  --send --address 

Replace with the path to your private key file, and with the correct Trezor address.

3. Update Safe-CLI Version

Ensure that your safe-cli version is up-to-date, as older versions might not support certain features or have compatibility issues.

npm install -g @truffle/ganache-safe-cli

Run ganache --version to verify the version. If you’re using a different platform (e.g., macOS), ensure that the safe-cli is installed and configured correctly.

4. Check Trezor Wallet Version

Verify that your Trezor wallet has the latest software update, as this might resolve compatibility issues.

trezor-cli -v

Additional Tips:

• Make sure you’re using the correct version of the Trezor wallet for your Ethereum network (e.g., Goerli or Mainnet).

• If you’ve recently installed a new operating system or updated to a newer version, ensure that your safe-cli is compatible.

• If none of the above solutions resolve the issue, try deleting your local blockchain data and then re-importing the Trezor address.

By following these steps, you should be able to resolve the “Address mismatch” or “Error validating signature” errors when using the safe-cli with a Trezor wallet.
