[ service 06 — secure ]
Tested before a dollar touches them.
DeFi is the hardest software environment there is: adversarial, permissionless, and unforgiving. We've built lending markets, a perpetuals DEX, and liquidation-protection agents from first principles — over 2,000 tests across our flagship builds — and we bring that same standard to protocol work for clients.
[ what we build ]
Lending & borrowing markets
Aave-class money markets — interest rate models, collateral factors, liquidation engines — built and torture-tested from scratch.
Perpetuals & derivatives
Perps DEX architecture: funding rates, margin, oracle integration, and the AI agent layers that can trade on top of them.
Vaults & yield strategies
ERC-4626 vaults and Solana equivalents with strategy isolation, so one bad strategy can't drain the house.
Liquidation & risk tooling
Keepers, health-factor monitors, and protection agents that act before a position gets liquidated — we run one live on Solana.
Invariant monitoring
Real-time monitoring of protocol invariants in production — the tooling we're building as a product, applied to your protocol.

[ timeline ]
Typical engagement: 4–12 weeks depending on protocol scope; testing is never the compressed phase.
[ straight answers ]
What proof do you have that you can do this?
Open receipts: a 27-contract lending protocol with 670 tests, a 26-contract perps DEX with 493 tests live on Sepolia, and a liquidation-protection agent live on Solana. See the Results page — every number is real.
How do you approach security?
Invariants first: define what must never happen, encode it as continuously-checked properties, then fuzz for violations. Unit tests tell you code does what you expected; invariants tell you it can't do what you feared.
Do you work with anonymous teams?
We evaluate case by case. What's non-negotiable is that the protocol itself is transparent — verified contracts, documented mechanics, and no design that only works if users don't read the code.
