DeFi Platform Development for Production Protocols
WeiBlocks builds custom DeFi protocols — AMM DEXs, lending markets, yield strategies, perpetuals, and stablecoins. MEV-aware design, audit-ready by default, multi-chain (EVM + Solana).
Quick Answer
WeiBlocks delivers full DeFi platform development — DEXs, lending markets, yield vaults, perpetuals/derivatives, and stablecoin systems. Engineers with production-shipped experience on Uniswap V3/V4, Aave V3, Compound V3, Curve, Jupiter, and Raydium ecosystems. Audit prep is standard practice. Multi-chain coverage across Ethereum, EVM L2s (Base, Arbitrum, Optimism), and Solana. MEV-aware design for production trading. 255+ projects delivered including MBD Financials DeFi infrastructure.
Common Challenges for DeFi protocol founders and DAO treasuries
Forked Code, Forked Vulnerabilities
Most 'DeFi agencies' fork Uniswap or Aave and ship. The original team's bugs become your bugs. Custom mechanics need custom design.
MEV Exposure
Without MEV-aware design, your protocol becomes a sandwich-attack target. Users get extracted; volume migrates to competitors.
Oracle Manipulation
Single-source oracle dependencies are still the #1 root cause of DeFi exploits. Multi-source oracle aggregation isn't optional.
Liquidity Bootstrapping
Protocols without liquidity die. Tokenomics design, incentive programs, and integration with aggregators all matter from day one.
What We Build for This Vertical
Custom DEX Mechanics
Concentrated liquidity (Uniswap V3-style), V4 hooks, order book DEXs, RFQ systems, batch auctions for MEV protection.
Lending Protocol Design
Isolated vs. pooled lending, interest rate models, liquidation engines, oracle-driven mark prices, dynamic LTV.
Yield Vault Strategies
ERC-4626 vaults, auto-compounding strategies, restaking integrations, multi-strategy yield aggregators.
Perpetuals & Derivatives
Funding rate mechanics, oracle integration, liquidation cascades, insurance fund design, mark-price oracle aggregation.
Stablecoin Systems
Crypto-collateralized (MakerDAO-style), algorithmic (be careful), fiat-backed, hybrid models. Peg-stability mechanisms.
MEV-Protected Design
Commit-reveal, batch auctions, private mempools (Flashbots Protect), CoW-style settlement, sealed-bid auctions.
Compliance & Regulatory Considerations
Frameworks we design around when building for DeFi protocol founders and DAO treasuries. We pair this technical work with your legal counsel — we're not a law firm.
- Limited regulatory clarity in most jurisdictions
- OFAC compliance (sanctions screening)
- Token classification (Howey test for US)
- VARA awareness for UAE-facing DeFi
- Travel rule (FATF Recommendation 16)

Frequently Asked Questions
Do you build DeFi protocols from scratch or fork?
Both, scoped per project. New mechanics, novel tokenomics, or differentiated UX — from scratch. Variations on proven designs (lending market with custom oracle, AMM with different fee tier) — fork-and-extend. We recommend the right approach during scoping based on your differentiation goals and timeline.
How do you handle MEV?
Depends on protocol type. AMMs: batch auctions or sealed-bid orderflow auctions. Liquidations: keeper incentives with reasonable bonuses to avoid liquidation cascades. High-value transactions: Flashbots Protect or private mempool routing. We design MEV resistance from day one — it's not an afterthought.
What oracles do you use?
Chainlink Price Feeds is default for EVM mainnets, Pyth Network for Solana and many EVM L2s, Chronicle for Maker-compatible feeds, RedStone for novel asset types, and Tellor as a censorship-resistant fallback. Multi-source aggregation for high-value protocols.
Can you build DeFi with compliance gates?
Yes — permissioned DeFi for institutional use cases. KYC-gated pools, sanctions screening (OFAC integration), regional whitelists, transfer restrictions. We've built DeFi infrastructure for clients targeting institutional capital where unrestricted DeFi isn't an option.
What does a DeFi protocol cost?
Single contract DEX or simple lending market: $50K–$120K. Full protocol with multiple integrated contracts: $150K–$400K. Stablecoin systems with peg-stability mechanics: $200K+. Audit fees (paid to audit firm) typically $40K–$200K additional.
