Smart contracts, DeFi protocols, payment rails, and tokenized platforms — engineered with the rigor a system holding real value deserves. Security audits aren't an afterthought; they're part of the build.
Solidity, Vyper, and Rust contracts on EVM chains and Solana. Test-driven, gas-optimized, formally reasoned where it matters. Audit-ready from the first commit.
Lending, AMMs, vaults, staking, yield strategies. We build the protocol logic and the economic model — not just the code, but how the incentives compose.
ERC-20, ERC-721, ERC-1155, ERC-4626, custom standards. Minting flows, royalty distribution, governance tokens, vesting schedules — done correctly.
Wallet integrations (MetaMask, WalletConnect, Phantom, Smart Wallets), account abstraction, gas-sponsorship, transaction simulation, and the UX wrappers users expect.
Internal audit before external audit. Slither, Echidna, Foundry fuzzing, formal verification where it pays off. We coordinate with audit firms and ship the fixes.
The Graph subgraphs, custom indexers, on-chain dashboards, alerting. Because shipping a contract is half the work — operating it is the other half.
Not a meme token. Not a quick mint. Something with users, TVL, and real consequences. The bar for engineering on-chain is high — we meet it.
You have an existing platform and want to add wallet auth, payments, NFTs, or token-gated features without making it feel grafted on.
Your auditors flagged problems. Your team doesn't have on-chain depth. We bring senior smart-contract engineers in to triage and ship the fixes.
