Protocols, dApps, bridges, and L2s, built with the same rigor we'd bring to a third-party review. Ship faster without shipping vulnerabilities.
A signature prompt that hides what's being signed is a vulnerability. We build dApps that show users exactly what they're authorizing: typed data, decoded calldata, and clear simulation diffs.
We co-design the spec, write the contracts, and prove the invariants in one continuous loop. Auditability is a build-time property, not a post-hoc favor.
contract Vault { /// @notice shares ≤ assets always function deposit(uint256 a) external returns (uint256 s) { s = a * totalSupply / totalAssets; _mint(msg.sender, s); assert(totalSupply <= totalAssets); } }
Two-thirds of every dollar lost in Web3 has been lost on a bridge. We design messaging layers around that fact: verifier diversity, replay-proof nonces, and pause guardians wired in from commit one.
From sequencer and fraud-proof systems to ZK provers and DA layers, we design and ship the L2 stack with formal specs of the dispute game, escape hatches that actually escape, and operational tooling for the boring parts.
Tell us what you're building. We'll scope a minimal first delivery in a single 30-minute call.
