By the way, oksolc 0.2.2 is out!

Fixed a bunch of tricky Solidity edge cases: deep inheritance graphs, recursive structs, immutables, and source URL hash checks.
Also fixed ABI size arithmetic beyond 4 GiB... good luck 🙂
Still targeting solc 0.8.36 compatibility, exact same compiler output.

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.

[Alt Funds @AltFundsNetwork]

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.

@AltFundsNetwork Thanks for having our cofounder @hbbiok

[Henri 🆗 @hbbiok]

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).

oksolc updates

[Henri 🆗 @hbbiok]

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!

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.

@WuBlockchain @VitalikButerin @okx As agents start executing more complex transactions, verification becomes critical.

@OKcontract Chainwall is building the safety layer to make sure AI-driven onchain operations are understood and safe before execution.

@okx @VitalikButerin AI will interact with blockchain.

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 https://t.co/sLwR10jfNU

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.

Still optimizing oksolc, starting to focus on the YUL optimizer

Now up to 22% faster!

[Henri 🆗 @hbbiok]

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.

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 Labs | Chainwall @okcontract]

Yes, we chose this for "All Correct Contract"

And we're not done yet 👀

[World of Statistics @stats_feed]

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?
