DeFi Infrastructure

Lending Protocol Development

Lending protocol development demands rigorous security and economic modeling. Our team has built cross-chain DeFi infrastructure and contributed to products reaching $400M market cap. We understand the attack vectors, the edge cases, and what it takes to protect user deposits when real capital is at stake.

Our DeFi Lending Experience

We have architected cross-chain lending protocols where users deposit collateral on one blockchain and borrow assets on another. This required solving problems that single-chain lending protocols never face: cross-chain messaging latency, fragmented liquidity, and liquidation coordination across networks.

Our team also served as founding engineers for a government-grade crypto asset platform, giving us security instincts that inform every contract we write. Lending protocols hold user deposits directly. A single exploit can drain everything. We build with that reality in mind.

Whether you need a simple single-asset lending market or a complex cross-chain borrowing protocol with novel interest rate models, we bring experience from production DeFi systems to your project.

How Lending Protocols Work

DeFi lending protocols enable trustless borrowing and lending through smart contracts. Understanding the core mechanics helps inform architecture decisions.

Collateralized Lending

Users deposit assets as collateral to borrow other tokens. Configurable loan-to-value ratios, health factor monitoring, and position management for safe lending operations.

Interest Rate Models

Dynamic interest rates that respond to utilization. Jump rate models, kinked curves, and governance-adjustable parameters that balance lender yields with borrower costs.

Liquidation Mechanisms

Automated liquidation when positions become undercollateralized. Dutch auctions, fixed discount liquidations, and partial liquidation support to protect lender deposits.

Multi-Asset Markets

Support for multiple collateral and borrowable assets within a single protocol. Isolated and cross-collateral pools based on risk tolerance and use case requirements.

Technical Capabilities

Building a DeFi lending platform requires expertise across smart contracts, oracle systems, risk modeling, and cross-chain infrastructure.

Smart Contract Architecture

Modular lending contracts with upgradeability patterns, emergency pause functionality, and clear separation between core logic and configuration. Built for security audits.

Oracle Integration

Price feed integration with Chainlink, Pyth, and custom oracle solutions. Multi-oracle fallbacks, staleness checks, and circuit breakers to prevent price manipulation attacks.

Cross-Chain Lending

Lending protocols that operate across multiple blockchains. Deposit on one chain, borrow on another. We have built cross-chain lending infrastructure from the ground up.

Risk Parameter Management

Configurable collateral factors, borrow caps, supply caps, and reserve factors. Governance integration for decentralized parameter adjustments.

Flash Loan Support

Optional flash loan functionality for capital-efficient arbitrage and liquidations. Fee structures and callback patterns that maintain protocol security.

Analytics and Monitoring

Real-time protocol health dashboards, TVL tracking, utilization rates, and position monitoring. Clear visibility for users, governance, and risk managers.

Security Considerations

Lending protocols are high-value targets. We architect with security as the foundation, addressing known attack vectors and modeling novel threats.

Oracle Manipulation Protection

Time-weighted average prices, multi-oracle consensus, and deviation thresholds prevent attackers from manipulating collateral values to drain lending pools.

Reentrancy Guards

All state-changing functions protected against reentrancy attacks. Checks-effects-interactions pattern enforced throughout the codebase with explicit guards on critical paths.

Flash Loan Attack Prevention

Interest accrual and price calculations designed to prevent flash loan manipulation. Block-based rate updates and snapshot mechanisms where appropriate.

Economic Attack Modeling

We model attack vectors including bad debt scenarios, liquidation cascades, and governance attacks. Risk parameters set based on empirical analysis, not assumptions.

Formal Verification Ready

Contract structure and invariants documented for formal verification. We work with auditors to ensure mathematical properties hold under all conditions.

Emergency Response Systems

Multi-sig controlled pause functionality, guardian roles for urgent parameter changes, and graceful degradation patterns when external dependencies fail.

Oracle and Price Feed Integration

Accurate price data is critical for lending protocols. Collateral valuation, liquidation triggers, and interest calculations all depend on reliable oracles.

Chainlink Price Feeds

Integration with Chainlink oracles including heartbeat checks, deviation monitoring, and fallback handling for stale or missing data.

Pyth Network

High-frequency price updates from Pyth for assets requiring more responsive pricing. Confidence interval validation and pull-based update patterns.

TWAP Oracles

On-chain time-weighted average price calculations from DEX liquidity pools. Useful for long-tail assets without centralized oracle support.

Multi-Oracle Fallbacks

Primary and secondary oracle sources with automated failover. If one oracle fails or deviates significantly, the protocol continues operating safely.

Why Hexmount for Lending Development

Building lending protocols requires more than Solidity skills. It demands understanding of DeFi economics, security architecture, and production operations.

Cross-Chain DeFi Experience

We have built lending infrastructure that spans multiple blockchains. Cross-chain collateralization, unified liquidity, and coordinated liquidations across networks.

Security-First Mindset

Our founding team built government-grade crypto custody systems. When contracts hold user funds, we apply the same rigor that satisfies national security requirements.

Economic Modeling

Interest rate curves, liquidation incentives, and risk parameters that create sustainable protocols. We design for long-term health, not just launch day metrics.
