As a follow-up to our prior proposal review, OpenZeppelin has conducted an audit of the the Franchiser contracts provided by Event Horizon on behalf of the ARDC. These contracts will allow the Arbitrum DAO to transfer a token through the FranchiserFactory to a Franchiser contract which will delegate its voting power to Event Horizon, allowing them to vote on proposals.
In short, we found no security issues with the contracts and our notes contain only recommendations for coding practices as well as a consideration for removing an unnecessary feature for additional token subdelegation. We invite the community review the full details of our audit and conclusion here:
