Hi all, Trust, the top warden from [our Code4rena contest](https://forum.thegraph.com/t/announcing-the-code4rena-contest-for-the-arbitrum-grt-bridge/3624), has now completed the review of the mitigations we implemented for the issues found in the contest. No new high/medium severity issues were found, and there’s a few QA/low severity ones that can be fixed in a future upgrade. We’re also almost done with our testnet testing plan, and the Council has already voted in favor of deploying this as outlined in [GIP-0040](https://forum.thegraph.com/t/gip-0040-l2-bridge-and-protocol-deployment/3695); you can see the vote in [Snapshot](https://snapshot.org/#/council.graphprotocol.eth/proposal/0x8c3c94e6a3064023eac582d609041524c1f41b70bece62f6c58d303faa42b7e8). This means we’re getting ready to deploy this to mainnet / Arbitrum One soon. We’ll update here when we do 🙂 --- _[View the full topic](https://forum.thegraph.com/t/gip-0031-arbitrum-grt-bridge/3305)._
