Investigate feasibility of ERC2771 for Flow EVM #858
Description
ERC-2771 is a standard for secure meta transactions on the Ethereum blockchain. It defines a way for users to delegate the signing of their transactions to a third-party service, called a meta transaction relayer. The relayer then submits the transaction on behalf of the user, paying the gas fee.
The primary purpose is to enable third-party EVM developers, when using the ERC2771 technology stack they are familiar with to develop products, to opt out of relying on third-party relayer services like Gelato (as Gelato introduces additional latency and extra costs) and instead directly utilize the solution we provide.I believe this solution could be a new private deployment or an extension of a new service module within the EVM Gateway. The key is to allow them to achieve gas fee sponsorship using the approach they are accustomed to. (The current GAS_PRICE=0 configuration is ineffective for wallets like MetaMask, so they still need to rely on the ERC2771 solution on the frontend.)
This could be useful for providing a solution for gas fee sponsorships, without having to use 3rd-party services.
