…design Rollup and rollup proxy admin are owned by L1 upgrade executor, on which the rollupOwner has EXECUTOR role. When creating token bridge for rollup, now rollupOwner has to be provided as well. L1 creator will check that rollupOwner has EXECUTOR role on the upgrade executor (which is fetched via .owner()). Aliased L1 upgrade executor and rollup owner are then made executors on L2 upgrade executor.

Entrypoint is still the same -
function createTokenBridge(address inbox, uint256 maxGasForContracts, uint256 gasPriceBid)inL1AtomicTokenBridgeCreator.Function will figure out if ETH or ERC20 token is used to pay for retryable fees and do the appropriate calls. If ERC20 fee token used, it is expected that amount needed to pay for retryables is already approved (msg.sender needs to approve
L1AtomicTokenBridgeCreatorto spend them). Creator will then move fee tokens to inbox.Scripts for deploying creator and creating token bridges are included.
Ie. to deploy creator on Arbitrum goerli, first prepare
.env, then run:yarn run deploy:goerli:token-bridge-creatorTo create new token bridge for Orbit chain run this with rollup address as argument:
yarn run create:goerli:token-bridge -- '0x05615057779Fda653f18469FcF2e87d0A02B815E'To test deployment set endpoints in .env, and have local
network.jsonfile with addresses, then run:yarn run test:tokenbridge:deployment
