Engineered for composability.
We build smart contracts and decentralized applications on Ethereum and Solana. The work includes explicit system properties, invariant tests, fuzzing, and monitoring, with particular attention to how the contracts interact with other protocols.
Smart contract development
Solidity and Anchor programs written against explicit invariants - the properties that must never break, checked continuously.
Full dApp builds
Contracts plus the frontend, indexing, and wallet UX around them - one team, no seams between the chain and the interface.
Token & NFT systems
ERC-20/721/1155 and SPL token systems with vesting, distribution, and governance mechanics that hold up under adversarial reading.
Fuzzing & invariant testing
Foundry fuzz campaigns and invariant suites hunting the states your unit tests never imagined - before mainnet does.
Audit preparation
Documentation, threat models, and test coverage prepared so your external audit spends its hours finding real issues, not asking questions.
Typical stack
Timeline
Typical engagement: 3–8 weeks depending on protocol surface and testing depth.
Ethereum or Solana?
Both, natively - Solidity/Foundry on the EVM side, Rust/Anchor on Solana. The right chain depends on your users and liquidity, and we'll give you a straight answer about which fits.
Do you audit your own code?
We run rigorous internal review - fuzzing, invariants, self-audit - and still recommend an independent external audit for anything holding meaningful value. Both, not either.
Can you rescue a half-finished protocol?
Often, yes. We start with a code review and honest go/no-go assessment - sometimes finishing costs less than restarting, sometimes it doesn't. You'll know which before spending.
