Hire DeFi Developers — Production Protocols, Not Forks
WeiBlocks builds custom DeFi protocols — DEXs, lending markets, yield strategies, derivatives, stablecoins. Audit-ready, MEV-aware, gas-optimized. Available in 2 weeks.
Quick Answer
WeiBlocks provides pre-vetted DeFi developers with production-shipped experience on DEXs (AMM + order book), lending protocols, yield strategies, perpetuals/derivatives, and stablecoin systems. Engineers know the DeFi standards stack (Uniswap V3/V4, Aave, Compound, Curve, Jupiter, Raydium) first-hand. Audit prep is standard. Engagements: staff augmentation, project delivery, or hybrid. Available within 2 weeks.
Pricing: Starting at $110/hr · $18K/mo FTE
What DeFi Developers Do at WeiBlocks
AMM & DEX Development
Uniswap V2/V3/V4-style AMMs, order book DEXs, concentrated liquidity, custom curves.
Lending Protocols
Aave/Compound-style isolated and pooled lending, oracle-based liquidations, interest rate models.
Yield Strategies
Vault patterns (ERC-4626), auto-compounding strategies, yield aggregators, restaking.
Perpetuals & Derivatives
Funding rate mechanics, oracle integration, liquidation engines, mark-price design.
Stablecoins
Crypto-collateralized, algorithmic, and fiat-backed stablecoin contracts. Peg-stability mechanisms.
MEV Awareness
MEV-protected designs, batch auctions, commit-reveal patterns, private mempools (Flashbots Protect).
Engagement Models
Staff Augmentation
DeFi engineers embedded in your protocol team. 3+ months minimum.
Project Delivery
Defined DeFi protocol (DEX, lending market, derivatives platform) scoped, built, audit-prepped, and deployed.
Protocol Architecture
Short engagement (4–8 weeks) to design protocol architecture, tokenomics, and security model. Useful before a bigger build.
Tech Stack
The tools and libraries our DeFi developers use day-to-day in production engagements.

Frequently Asked Questions
Do you build DeFi protocols from scratch or fork existing ones?
Both, depending on your needs. New mechanics or token designs: from scratch. Variations on proven designs (e.g. lending market with custom oracle): fork-and-extend Aave V3 or Compound V3 to save time. We'll recommend the right approach during scoping.
How do you handle MEV?
Depends on protocol type. For AMMs: batch auctions or off-chain matching. For liquidations: keeper incentives + reasonable bonuses. For high-value txs: Flashbots Protect or private mempools. We design with MEV in mind from day one.
Which oracles do you use?
Chainlink Price Feeds (default for EVM mainnet), Pyth (Solana primary + EVM L2s), Chronicle, RedStone. For specialized assets, we build custom oracle infrastructure with multiple sources and aggregation.
Can you build DeFi protocols with regulatory compliance features?
Yes — KYC-gated transfers, regional whitelists, transfer restrictions, sanctions screening (e.g. OFAC). Permissioned DeFi for institutional use cases is a growing engagement type.
What does a DeFi protocol cost?
Single contract DEX or lending market: $50K–$120K. Full protocol with multiple integrated contracts: $150K–$400K. Audit fees (paid to audit firm) typically $40K–$200K. Staff aug: $110–$200/hr.
