Crossbook is a noncustodial hybrid decentralized exchange where traders sign EIP-712 orders off-chain as gasless intents, a pure Rust matching engine crosses them, and an on-chain Solidity settlement contract re-verifies every signature and limit and swaps tokens atomically. It runs both continuous price-time matching and a CoW-style batch auction with a uniform clearing price per pair, plus multi-token ring trades, all backed by a live dashboard, a PoC threat model, cross-implementation differential fuzzing, and CI across the engine and contracts.

Assayer is an open-source token safety scanner in Rust. Given an ERC-20 address and a chain RPC, it forks live chain state at a pinned block with revm, simulates a real buy and sell through the chain''s DEX, statically inspects the bytecode and on-chain state, and returns a structured risk report: can you actually sell it, what are the buy and sell taxes, and does it hide mints, blacklists, pausability, or owner backdoors. It runs cross-chain on BNB Chain, Ethereum, and Base, ships as an embeddable library on crates.io plus a CLI and a self-hostable HTTP service with a web UI, and is hardened by an adversarial multi-agent review, a real-token fixture suite, and a never-panic robustness contract.
