Ethereum: Sending ERC-20 Tokens via Safe CLI Not Working

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

• UI issues: The UI for sending transactions on CELO (Cosmos SDK) is not functioning correctly, preventing users from completing the task.

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

Step 1: Verify EVM Client Version

Before attempting to fix the issue, ensure that your EVM client version is up-to-date:

evm --version

If you’re using a recent version of the Safe CLI or an older version, consider updating it.

Step 2: Check for Insufficient Signature Approvals

Verify that the send_erc20 tx command requires sufficient signature approvals. You can do this by running:

evm --accounts --accounts  send_erc20 tx --gas 2000000 --gasPrice 10000000000000000000000000000000000 --from 

If the account is not receiving enough signature approvals, you’ll see an error message indicating that the transaction will fail.

Step 3: Update UI for Sending Transactions on CELO

Try updating your Cosmos SDK to the latest version:

cosmos-sdk update

Then, run the cosmos-sdk CLI with the following options:

cosmos-sdk --ui  --chain dev

This will display the UI for sending transactions on CELO.

Step 4: Resolve EVM Client Issues

To resolve the EVM client issues, you can try:

• Manual signature signing: Use a tool like sigchain to manually sign the transaction.

• EIP-1277 updates: Ensure that your EVM client version is up-to-date with the latest EIP-1277 fixes.

Conclusion

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

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