Engineering the decentralized economy
Production DeFi engineering studio · San Francisco
Zendarox is a DeFi engineering studio founded in San Francisco in April 2021. We build production-grade protocols for clients — and develop Zendarox Vault, our flagship lending product, in parallel.
We scope work to real requirements: smart contract architecture, Solidity development, security audits, cross-chain integrations, tokenomics, and launch operations for lending protocols, AMMs, yield vaults, and institutional treasury systems.
We ship what your requirements doc asks for — not a template fork.
| Practice | What we deliver |
|---|---|
| DeFi Protocol Studio | Lending markets, AMMs, ERC-4626 vaults — architecture through deployment playbooks |
| Smart Contract Security | Manual audits, Foundry fuzzing, invariant suites, remediation re-review |
| Cross-Chain & Messaging | Treasury modules, rate limits, pause hooks, relayer monitoring |
| Tokenomics & Governance | Emission schedules, ve-token modeling, mercenary LP stress scenarios |
| Institutional Design | Permissioned vaults, KYC-gated deposits, compliance reporting APIs |
Typical timelines: 2–4 weeks (audits) · 12–18 weeks (protocol builds) · 14–20 weeks (cross-chain)
| Vault |
Zendarox Vault — isolated lending markets with a yield router.
