Announcement of an announcement:
We'll soon, quite soon, publish our most comprehensive open-source contribution to the @Stacks ecosystem yet.
Stay tuned!
Happy to announce I've accepted an executive position @cyfrin, formally joining the leadership team as Head of Security Research.
We're working harder than ever to keep our clients safe while scaling our private audit business to handle epic demand.
🙏 Blessed 🙏
@0xcuriousapple I’m sure it wasn’t an easy choice, the guys at Guardians are truly some of the best to work with
Best of luck in what’s next I’m excited to see what you build!

We recently completed a security review for @GraniteBTC, a Bitcoin liquidity protocol built on @Stacks enabling users to borrow stablecoins against Bitcoin collateral through sBTC, developed by @trustmachinesco.
This engagement focused on reviewing fixes, hardening efforts, and protocol enhancements across the protocol’s lending system, covering changes across borrowing, liquidation flows, staking, governance, LP incentives, oracle integrations, withdrawal logic and related core functionality.
Granite combines Bitcoin-backed liquidity access with design choices such as isolated collateral, soft liquidations, and Bitcoin-native infrastructure.
Happy to support teams building BTCfi infrastructure. Always a pleasure working with security-oriented teams pushing the ecosystem forward.
Truly trailblazers. C4 created a path where there wasn’t one and a global community for so many of us to actually make a career in this space.
Change is apart of life but It’s sad nonetheless to see C4 come to an end.
Thank you C4 🙏
Two of my projects were selected for the @thedaofund Ethereum Security QF Round on @Giveth.
The round has a 500 ETH matching pool (roughly $1M+) backing around 100 Ethereum and L2 security projects.
It uses Quadratic Funding, which means $1 from 100 donors unlocks far more from the matching pool than $100 from 1 donor.
Voting is open until May 14. Here's what they do 🧵

One of the more detail oriented articles we've published, but the value it brings is significant.
As an auditor, it's interesting to see how one account can map to different addresses on Stacks, depending on whether you're on testnet or mainnet.

Cross-chain bridges remain critical infrastructure, proof verification is the core of their security model.
New disclosure on our research page: a vulnerability in the Polygon Plasma bridge that allowed transaction proofs to be forged.
At the time of discovery, $800M in POL was at risk, exploitable in a single transaction with no prerequisites.
The research covers how the proof verification breaks, how the exploit was built, and what it means for bridge security.
