Description

Helper contract that allows the sequencer to submit both a state commitment batch and tx batch in a single transaction. This is the contract that will be whitelisted for instant submission to the CanonicalTransactionChain.

NOTE: This PR builds off of #143

LGTM 👍

Only suggestions are to add a bit more documentation as to how the contract is meant to fit into the bigger picture.

+import {CanonicalTransactionChain} from "./CanonicalTransactionChain.sol";
+import {StateCommitmentChain} from "./StateCommitmentChain.sol";

Could you add some context comment as to what this is meant to do, who is meant to interact with it, etc.?

+    stateCommitmentChain = StateCommitmentChain(_stateCommitmentChain);
+  }
+
+  function appendTransitionBatch(


Could you add a bit about what the bytes of the _txBatch and _stateBatch represent? Is it just tx calldata? Is it signed transactions, how are they encoded, etc.?

If there are other functions that should only be called by the sequencer, would move this into some utils lib. It's fine here for right now though 😄
