same contract using create2 after calling selfdestruct?
The below is a Foundry test:
// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.13;
import "forge-std/Test.sol";
contract Factory {
event WalletCreated(address wallet);
function deployWallet() external returns (address) {
uint256 salt = 0x123456789; // Specify a unique salt value for create2
address walletAddress;
bytes memory bytecode = type(Wallet).creationCode;
assembly {
// Bytecode of the Wallet contract
// Calculate the address using the create2 opcode
walletAddress := create2(0, add(bytecode, 0x20), mload(bytecode), salt)
if iszero(extcodesize(walletAddress)) {
revert(0, 0)
}
}
emit WalletCreated(walletAddress);
return walletAddress;
}
}
contract Wallet {
constructor() {
}
function destroyMe() public {
selfdestruct(payable(address(msg.sender)));
}
}
contract MetamorphicTest is Test {
Factory public factory;
address public wallet1;
address public wallet2;
function _getCodeHash(address _account) private view returns (bytes32 codeHash){
assembly {
codeHash := extcodehash(_account)
}
}
function setUp() public {
factory = new Factory();
}
function testMeta() public {
wallet1 = factory.deployWallet();
console.log(address(wallet1));
Wallet(wallet1).destroyMe();
wallet2 = factory.deployWallet();
console.log(address(wallet2));
assertEq(wallet1, wallet2);
}
}
Foundry doesn't selfdestruct the contracts
You can do it here too
