On March 22, Offchain Labs disclosed two serious vulnerabilities in the Optimism OP Stack fraud proofs, which were identified during a testnet review. The vulnerabilities were communicated privately to the OP Labs team, fostering a collaborative effort to enhance security across the Ethereum network. This proactive approach allowed for a coordinated response, ensuring that the issues could be addressed before being exploited in production environments. The discovery was part of a broader initiative to secure the OP Stack system, which is crucial given its widespread use across various Layer 2 blockchains. A subsequent audit contest by Sherlock DeFi, starting March 27, has pushed these OP Stack fault proofs closer to deployment on the OP Mainnet. Additionally, Stage 1 of the fault proofs is set to launch this summer.

Fault Proofs + Stage 1 for OP Stack is coming this summer. This will be a big step forward given how many L2’s are on OP Stack. Thanks to everyone who participated in the audit! https://t.co/qoRCXOMAbG
On March 27, we began a @sherlockdefi audit contest for the proposed OP Stack fault proof system. Now, the contest has entered the escalation period and fault proofs are officially one step closer to OP Mainnet! https://t.co/mtUfqqhvN9
Today, we disclosed two serious vulnerabilities in OP stack fraud proofs. Ethereum is better when we work together 🤝 Our team has a ton of expertise in building fraud proof systems, and I’m proud of our team for helping make Ethereum safer for everyone 💙🧡❤️ https://t.co/fo4bbjArpx
Today, we disclosed two serious vulnerabilities in the recently released OP Stack fraud proofs. We coordinated closely with the OP Labs team on this disclosure. We’re all on team Ethereum, and happy to lend resources to make Ethereum safer for everyone. https://t.co/vC4SWBdTuZ
wow very interesting! it seems Arbitrum found 2 critical security issues in Optimism on testnet re: proofs not working properly https://t.co/7v74LTmpnB
