Announcing the Code4rena contest for the Arbitrum GRT bridge

Hello everyone,

As part of our work towards scaling The Graph by deploying the network to L2, we’re launching an audit contest with Code4rena. We’re inviting the community to participate. The contest will last five days, from October 7th to October 12th, and has a 50,000 USDC prize pool!

This is not a bug bounty. The contest has guaranteed payouts for all legit findings.

This audit contest will be focused on the bridge that will allow GRT to be sent to Arbitrum and back to mainnet Ethereum. The Wardens who audit will help make the bridge and the community’s move to L2 as secure as possible. This contest will complement a previous audit by OpenZeppelin.
