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.

What we build

Protocols we ship, end-to-end.

Each comes with the contracts, the off-chain infra, and the UI.

01

DEX & AMM

Swaps, pools, concentrated liquidity.

  • Constant-product & concentrated AMMs
  • Order-book / hybrid DEXes
  • Router, LP, and fee logic
02

Lending markets

Borrow, collateral, liquidations.

  • Over-collateralized & isolated markets
  • Interest-rate models
  • Liquidation engine & bots
03

Staking & yield

Rewards that don't leak.

  • Single & LP staking
  • Liquid staking
  • Yield vaults & strategies
04

Perpetuals

Leverage, funding, risk.

  • Perp DEX & funding logic
  • Margin & risk engine
  • Oracle & price-feed integration
05

Off-chain infra

The parts users never see.

  • Oracles & keepers
  • Indexers & subgraphs
  • Liquidation & arb bots
06

Security & economics

Where DeFi actually breaks.

  • Oracle-manipulation & MEV review
  • Flash-loan attack paths
  • Audited before mainnet

The process

Spec to mainnet.

~12 weeks for a focused protocol. Fixed quote, weekly cuts.

01Spec & economics
02Contracts
03Off-chain infra
04Audit
05Front end
06Mainnet + handover
We pin down the protocol math and the economic risks first, then build contracts and the keeper/oracle infra, audit everything, and ship the front end. You get weekly Friday cuts and full ownership of every key, repo, and contract at handover.

What does a DeFi protocol cost to build?

It comes down to the protocol type, the economic and security scope, the off-chain infra, and the audit. We scope it and give a fixed quote. The audit alone is a big driver — see how that's priced in our Smart Contract Audit Cost guide.

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.
