How can I perform a gasless transaction for my MetaTransactionTest
smart contract using backend-controlled wallets?
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
import "@openzeppelin/contracts/metatx/ERC2771Context.sol";
contract MetaTransactionTest is ERC2771Context {
event MetaTransactionExecuted(address indexed sender);
constructor(address trustedForwarder) ERC2771Context(trustedForwarder) {}
function executeMetaTransaction() public {
address sender = _msgSender();
emit MetaTransactionExecuted(sender);
}
function versionRecipient() external pure returns (string memory) {
return "1.0.0";
}
}
I have backend-controlled wallets and need to implement gasless transactions. Any guidance or examples on how to achieve this would be greatly appreciated.
