DeFi protocols, spec to mainnet. Audited, in ~12 weeks.
Shazra Labs is a DeFi development company that ships audited protocols end-to-end: AMMs and DEXes, lending markets, staking, yield, and perpetuals. We don't just write the contracts; we model the economics that break protocols (oracle manipulation, MEV, flash loans, liquidations) and build the keepers, oracles, and UI that keep it running. Audit-first, fixed quote, full handover.
What it is
What DeFi development takes
DeFi is where bad code and bad economics both cost real money, instantly. Building a protocol means more than smart contracts: it's the AMM or lending math, the oracle and keeper infrastructure, the liquidation and risk logic, and a front end users can trust with their funds. We build all of it, and we review the economics as hard as the code.

- Oracle & price-feed integration
Off-chain infra
The parts users never see.
- Oracles & keepers
- Indexers & subgraphs
- Liquidation & arb bots
Security & economics

DeFi development FAQ
People also ask
What is DeFi development?
Building decentralized finance protocols (DEXes and AMMs, lending and borrowing markets, staking, yield strategies, and perpetuals) as audited smart contracts plus the front end and off-chain infrastructure (indexers, keepers, oracles) they need to run safely on mainnet.
What kinds of DeFi protocols do you build?
AMMs and order-book DEXes, over-collateralized and isolated lending markets, staking and liquid-staking, yield vaults and strategies, and perpetuals. We also build the supporting pieces: oracles, keepers, liquidation bots, and dashboards.
How long does it take to build a DeFi protocol?
A focused protocol typically goes from spec to audited mainnet in around 12 weeks, depending on scope and audit timeline. We scope it up front and give you a fixed quote and a weekly delivery cadence. See the 12-week DeFi playbook.
How do you handle DeFi security and economic risk?
Every contract is audit-first: static analysis, fuzzing and invariants, and manual review before mainnet, plus an external audit for high-value protocols. We also model the economics: oracle manipulation, MEV, flash-loan paths, and liquidation behavior. Not just the code.
Which chains do you build DeFi on?
EVM chains (Ethereum, Base, Polygon, Arbitrum, Optimism, Avalanche) and Solana, chosen by liquidity, fees, and your target users.
