Build & Ship

Everything at a protocol's core: production contracts and audits, DeFi primitives, tokenization, and staking.

Smart Contracts & Security

Production smart contracts and the security around them: Solidity and Rust development, independent audits and pre-audit hardening, QA automation, and live-incident response. We hold code to a standard we wrote, Solhint, the linter used by 1M+ developers.

Smart Contract Development

Production Solidity, Plutus, and Rust for DeFi, RWA, and infra, built from audited reference architectures. Multi-chain, with the frontend, subgraph, and tooling around each contract.
