This is the bytecode used for minimal proxy address prediction and deployment in createEscrow() and predictEscrow():
createEscrow()
predictEscrow()
function createEscrow(address user) internal returns (IEscrow instance) { assembly { let ptr := mload(0x40) mstore(ptr, 0x3d602d80600a3d3981f3363d3d373d3d3d363d73000000000000000000000000) mstore(add(ptr, 0x14), shl(0x60, implementation)) mstore(add(ptr, 0x28), 0x5af43d82803e903d91602b57fd5bf30000000000000000000000000000000000) instance := create2(0, ptr, 0x37, user) } require(instance != IEscrow(address(0)), "ERC1167: create2 failed"); emit CreateEscrow(user, address(instance)); }
It is based on the OpenZeppeling code which has been recently updated to a somewhat more optimized version.
