Protecting privileged onchain operations https://xitter.cf/t.co/Xx6yLshUEI

Joined December 2020
Onchain operations security goes far beyond smart contract audits. Even audited protocols can remain vulnerable through compromised signers, malicious front ends, custody or cloud infrastructure exploits. As institutional adoption grows, we need to rethink how we approach security across onchain finance. 🎙️ Our cofounder @hbbiok joined Mike and Skyler on @AltFundsNetwork podcast to discuss these challenges, lessons from past security incidents, and how blockchain technology itself can become part of the solution.
Why smart contract audits aren’t enough to secure crypto assets? Henri Binsztok of @OKcontract explains how compromised signers, malicious front ends, and AI-driven cyberattacks expose critical gaps in DeFi security—and how Chainwall aims to add another layer of on-chain protection. #CryptoSecurity #DeFi #Blockchain

Very busy day today I almost forgot to tell that oksolc 0.2.1 is out! Make sure to update. Many fixes thanks to Xiaohai Xu (sahuang on GH). github.com/okcontract/oksolc

Pushed multiple improvements to oksolc today Major optimization to our slowest protocol in benchmark: Sablier comes down from 74s to 54s Still the same byte output Oh and we’re now using zig 0.17 Wish you all a good WE! github.com/okcontract/oksolc

Thanks a lot to @hackerbane for the first audit of oksolc! We reviewed all 29 findings and fixed 21, including one critical issue. We are happy to see the community contributions towards a better, secure Solidity compiler. oksolc GitHub is: github.com/okcontract/oksolc Merged PR (including the report) is: github.com/okcontract/oksolc…

Nice to see oksolc, our Solidity compiler implemented in Zig, mentioned by the Ethereal news. Thanks! If you building on Solidity and want to speed up your development, oksolc might save your precious time github.com/okcontract/oksolc…

The SEC’s new proposal marks an important development for crypto asset custody: → Crypto assets could be held in self-custody under certain circumstances → State trust companies could serve as custodians for client and regulated fund crypto assets Chainwall is designed to make self-custody secure — allowing owners to maintain direct control of their assets while accessing onchain yield safely. sec.gov/newsroom/press-relea…

Still optimizing oksolc, starting to focus on the YUL optimizer Now up to 22% faster! github.com/okcontract/oksolc

We got tired of waiting 10 minutes for Solidity builds, so we built oksolc in Zig. Same bytecode. 5×+ faster on many contracts. Our builds: 10 min → 2 min Incremental large changes: 700s → 99s If the bytecode ever differs, please tell us. Huge thanks to the Solidity team. github.com/okcontract/oksolc

AI agents may automate the work, but they do not solve the security problem. @hbbiok explains why privileged actions still need to be protected, and how blockchain-based timelocks can add a layer of security before dangerous operations like sending money or approving access can be executed. @okcontract

Yes, we chose this for "All Correct Contract" And we're not done yet 👀
How old were you when you found out that “OK” started as a joke misspelling of “all correct” and somehow became one of the most used words on Earth?

Join us today at the Singapore GUG meetup, hosted by SQ Collective! Our founder @hbbiok will share how frontier AI models are changing cybersecurity — from discovering serious software vulnerabilities to what defenders can do about it. We’ll discuss: - what is already happening, - where these capabilities are heading, - and what defenders can do to secure systems and operate around the clock in this new environment.

🎲 Randomness is the root of every crypto wallet. If the seed is weak, everything built on it is weak. 🔑 Key generation deserves the same scrutiny as transaction signing. So which pseudorandom number generator can you actually trust? 🛡️ Trust a process you can verify: → Know the exact code generating the secret → Combine independent entropy sources → Generate keys offline → Verify the public address independently → Erase the temporary environment when finished
