DEFI PROTOCOLS

On-chain finance, engineered
for real scale.

AMMs, lending protocols, and yield systems engineered for on-chain value at scale. Security-audited, economically sound, mainnet-proven.

PROTOCOL TYPES

The DeFi stack, end to end.

AMMs & DEXes

Constant product (xy=k), concentrated liquidity (Uniswap v3/v4 style), CFMM variants, and hybrid AMMs with dynamic fees and oracle integration.

Lending & Borrowing

Over-collateralized lending markets with isolated mode, cross-collateral positions, liquidation mechanisms, and interest rate models.

Yield Aggregators

Auto-compounding vaults, strategy-based yield optimization, and ERC-4626-compliant vault implementations with multiple strategy managers.

Liquid Staking

LST protocols with rebasing or non-rebasing token designs, validator integration, withdrawal queues, and governance participation.

Derivatives & Options

On-chain options vaults, perpetual futures protocols, and structured product vaults with automated payoff settlement.

Governance & DAOs

On-chain governance with timelocks, vote delegation, off-chain signaling integration, and treasury management contracts.

DEFI SECURITY

What keeps DeFi protocols safe.

Oracle securityTWAP requirements, multi-oracle configuration, flash loan resistance

Liquidation designHealthy incentive margins, bad debt prevention, liquidation efficiency

Reentrancy guardsCEI pattern, mutex locks, safe external call patterns

Incidents

Audit rounds

Meridian needed a lending protocol competitive with Aave and Compound, with novel features including isolated collateral mode and yield optimization. We designed the economic model, built the contracts, ran three audit rounds, and launched to mainnet without a single incident.

FAQ

DeFi protocol questions.

AMMs (constant product, concentrated liquidity, hybrid), lending/borrowing markets, yield aggregators, liquid staking protocols, options vaults, and derivatives. If it involves on-chain financial logic, we've likely built it or something adjacent.

We model incentive structures using game theory and historical data from comparable protocols. We consider liquidity depth, emission schedules, lock-up mechanisms, and governance capture resistance. We strongly recommend economic simulation before mainnet.

TWAP-based price feeds as the default. Chainlink for off-chain data. Multi-oracle configurations for high-value decisions. Flash loan resistance baked into every price consumption point. We don't trust single oracle sources for liquidation decisions.

We design incentive programs that attract and retain genuine liquidity, not just mercenary capital. This includes emission schedules, LP fee structures, lock-up bonuses, and governance-aligned reward distributions.
