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 protocolβs 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.
We've completed our security audit for @AccountableData, reviewing an extension to their DeFi credit vault infrastructure.
Accountable is a key player operating at the intersection of DeFi and TradFi.
Their vault-based credit layer programmatically allocates capital across lending strategies, with over $160M deployed to generate risk-adjusted yield.
They are also building the Data Verification Network (DVN), a privacy-preserving infrastructure that verifies financial data directly at the source. It already secures $1B+ in assets across partners like Galaxy, Amber Group, and K3 Capital, positioning Accountable at the intersection of onchain finance and institutional reporting.
Security at this scale is never a one-off.
Just kicked off a new audit for an extension to a complex DeFi strategy system.
Good protocols don't treat audits as a one-time checkbox. Every production change deserves a security review.
From first contact to audit kickoff: < 24h.
Security doesn't end after the first audit.

We're consolidating and migrating some of our older technical articles to the Cyba blog.

Two recent additions worth revisiting:
After years of working in security, I've launched Cyba Blockchain Security @cybasecurity
This is a long-term commitment to building security properly; beyond audits, beyond reviews or tooling alone.
Long road ahead, but this is the right one for me.
