Hi folks, just wanted to share an update on this. The implementation for the bridge has been audited; you can find the audit report here - this report contains issues for a couple other PRs, so which issues from that report are relevant to this PR is summarized in this other document.
We’ve also carried out several tests on Goerli and Arbitrum Goerli so we’re quite confident in this implementation.
We’ve now put the bridge with the audit fixes into a new pull request. We still need to carry out some more testing on testnet but we’re getting closer.
Also note there’s now two competing proposals to how rewards can be handled in L2: GIP-0034 and GIP-0037.
This GIP and the bridge implementation are still valid nonetheless, and we should be able to deploy bridge + L2 (without rewards) independently to which of those two ends up being chosen.
