XChain account contract for Optimism, to issue L1 calls to L2

Cross Chain Acccount

This is a simple contract implementation for issuing commands to L2 contracts from L1 addresses. Optimism does not natively allow using msg.sender to get the L1 address, so we use a contract which checks that xDomainMsgSender is the expected l1 owner.

Test

yarn
# evm tests
yarn hardhat test
# ovm tests
yarn optimism:up && yarn test

Deploy an account

L1_OWNER=<the L2 contract's L1 owner> yarn hardhat run scripts/deploy.ts --network optimism
