Lending Protocol Smart Contract Audit & Hardening

Comprehensive security audits and proactive hardening for DeFi lending protocols. We identify critical vulnerabilities, provide actionable fixes, and strengthen your codebase against exploits.

PROVEN PROCESS

Our Audit & Hardening Methodology

A systematic, multi-layered approach to securing lending protocols. We don't just find vulnerabilities; we deliver production-ready, battle-tested code.

01

Architecture Review & Threat Modeling

We analyze your protocol's design against known attack vectors like flash loan exploits, oracle manipulation, and economic logic flaws before a single line of code is audited.

02

Automated & Manual Code Review

Combines Slither and Foundry-based fuzzing with deep manual review by senior auditors. We scrutinize every function for logic errors, reentrancy, and gas inefficiencies.

Economic Security Analysis

Stress-testing of liquidation engines, interest rate models, and reserve factors under extreme market conditions to ensure protocol solvency and user fund safety.

AUDIT & HARDENING PRIORITIES

Critical Security Focus Areas for Lending

Our audits target the most exploitable vectors in DeFi lending. We deliver a prioritized security roadmap with actionable fixes to protect your protocol's assets and users.

02

Liquidation Engine Integrity

Stress-testing of liquidation logic, incentive mechanisms, and keeper systems. We ensure liquidations are profitable, timely, and resistant to front-running or griefing attacks under volatile conditions.

Interest Rate Model Security

Mathematical verification of rate curve algorithms (linear, kinked, jump-rate). We audit for rounding errors, overflow risks, and ensure models behave predictably across all utilization ranges.

FROM REPORT TO PRODUCTION

Post-Audit Hardening & Remediation

An audit report is a starting point. We provide the technical execution to systematically fix vulnerabilities, upgrade your codebase, and deploy a secure, production-ready lending protocol.

01

Vulnerability Remediation

We implement fixes for all critical, high, and medium-severity issues identified in your audit. Our team writes the corrected Solidity code, conducts peer reviews, and ensures fixes do not introduce new attack vectors.

Critical/High Fixes
48-72h
Initial Patch Turnaround
02

Gas Optimization & Refactoring

Beyond security, we harden your protocol for efficiency. We refactor code to reduce gas costs for core functions (deposits, withdrawals, liquidations) by 15-40%, directly lowering user transaction fees and improving competitiveness.

Re-Audit Coordination & Liaison

We manage the entire re-audit process. We prepare the updated codebase, submit it to the auditing firm, and act as your technical liaison to clarify fixes and expedite the final approval, saving your team weeks of back-and-forth.
