Ethereum: Sending ERC-20 tokens via Safe CLI not working

As a growing community of developers and enthusiasts, we have encountered an issue with the Ethereum Virtual Machine (EVM) client (Safe CLI) when attempting to send ERC-20 tokens using the send_erc20 tx command. This article aims to provide insight into the issue and potential solutions.

Problem Description

The issue arises from a combination of factors:

• Insufficient Ownership: The EVM client is not receiving enough signature approvals to sign the transaction.

• User Interface Issues

  : The CELO (Cosmos SDK) transaction sending user interface is not working properly, preventing users from completing the task.

• Version Compatibility: The Safe CLI version is not compatible with Cosmos SDK v1.3.0.

Step 1: Check your EVM client version

Before attempting to fix the issue, make sure your EVM client version is up to date:

evm --version

Check if thesend_erc20 txcommand requires sufficient signature approvals. You can do this by running:

evm --accounts --accounts  send_erc20 tx --gas 2000000 --gasPrice 10

If the account does not receive sufficient signature approvals, you will see an error message indicating that the transaction will fail.

Step 3: Update the UI for sending CELO transactions

Try updating your Cosmos SDK to the latest version:

cosmos-sdk update

Then runcosmos-sdk CLIwith the following options:

cosmos-sdk --ui  --chain dev

This will bring up the UI for sending CELO transactions.

Step 4: Troubleshoot the EVM client

To troubleshoot issues with the EVM client, you can try:

• Signing with a manual signature: Use a tool like sigchain to manually sign the transaction.

• EIP-1277 updates: Make sure your EVM client version is updated with the latest EIP-1277 fixes.

Conclusion

After debugging the EVM client and UI, you should be able to successfully send ERC-20 tokens via the send_erc20 tx command on CELO. If you encounter any further errors or difficulties, please refer to the official Cosmos SDK documentation and the Ethereum Virtual Machine (EVM) client documentation for more information.

By following these steps, you will be on your way to resolving this issue and continuing to explore the exciting world of Ethereum and Cosmos.
