"What's up everyone, I'm super stoked to start this thread on smart contract auditing on Layer 2 scaling solutions. As we all know, Ethereum's transition to a 2.0 setup has opened up new doors for scalability, but it's also created new challenges in terms of security assurance. Who's out there working with L2 scaling solutions like Optimism and Arbitrum, and what's your take on the importance of contract auditing in this space?"
