Metamask Gnosis Safe Transfer Fails with EIP2930
As an Ethereum developer, you’re likely no stranger to the complexities of interacting with smart contracts and external wallets. However, when it comes to transferring assets across multiple contract interfaces, such as between a contract and a Gnosis safe, issues can arise quickly. In this article, we’ll delve into why using EIP2930 in your Metamask setup might be causing out-of-gas (OOG) errors for your transactions.
EIP2930: A Brief Background
The Ethereum Virtual Machine (EVM) 2.0 is built on top of the Web3.js and Ethers.js APIs, which support a standardized interface for interacting with smart contracts called EIP-2771. One of these interfaces is EIP-2930, which allows you to execute transactions from one contract to another using a specific ABI (Application Binary Interface).
The Issue: Out of Gas
When attempting to transfer assets across multiple contract interfaces, such as between a contract and a Gnosis safe, the EIP2930 function call may fail due to an “Out of Gas” error. This occurs because EIP-2771 allows for direct calls between contracts, which can lead to excessive gas usage if not properly managed.
The Problem with Using EIP2930 in Metamask
In your case, you’re using Metamask to execute a EIP2930 call from one contract to another. However, when you try to do so, the transaction is failing due to out-of-gas errors. This can be attributed to several reasons:
- Incorrect Call Order: When you make an EIP-2771 call using EIP-2930, it’s essential to ensure that your contract and Gnosis safe are properly ordered in the call stack.
- Insufficient Gas Budgeting: Without proper gas budgeting, your transactions might run out of gas before they reach their intended destination.
- Contract Interface Misconfiguration: Your contract’s ABI should match EIP-2930’s interface requirements for correct execution.
Solutions to Overcome Out-of-Gas Errors
To overcome these challenges and successfully use EIP-2930 in your Metamask setup, follow these best practices:
- Verify Contract Interfaces
: Ensure that your contracts’ ABIs are correctly defined and match the requirements of
EIP-2930.
- Proper Order of Calls: Make sure you’re ordering your contract calls correctly to avoid out-of-gas errors.
- Manage Gas Budgets
: Implement gas budgets for each transaction to prevent excessive spending.
- Monitor Transactions: Keep a close eye on your transactions’ progress and adjust the call order or gas budget as needed to ensure successful execution.
By following these guidelines, you should be able to successfully execute EIP-2930 calls in your Metamask setup without encountering out-of-gas errors.
