Smart Contract Security Audit for Gateways

Expert security review and penetration testing for Bitcoin and Lightning payment gateway smart contracts. We identify and remediate critical vulnerabilities to protect your funds and users.
Chainscore © 2026
overview
CORE INFRASTRUCTURE

Smart Contract Development

Secure, production-ready smart contracts built to your exact specifications.

We architect and deploy custom smart contracts that form the foundation of your Web3 product. Our development process ensures security-first design, gas optimization, and audit readiness from day one.

  • Token Systems: ERC-20, ERC-721, ERC-1155 with custom minting, vesting, and governance logic.
  • DeFi Protocols: Automated Market Makers (AMMs), liquidity pools, staking, and yield strategies.
  • Enterprise Logic: Multi-signature wallets, access control, and complex business workflows on-chain.
  • Security Standard: Built with Solidity 0.8+ and OpenZeppelin libraries, following established patterns.

We deliver battle-tested contracts with comprehensive documentation, enabling your team to launch confidently in 4-6 weeks.

PROVEN PROCESS

Our Security Audit Methodology

A systematic, multi-layered approach designed to uncover critical vulnerabilities in gateway smart contracts, ensuring robust security and operational integrity before mainnet deployment.

01

Architecture & Design Review

We analyze your gateway's system architecture, threat models, and economic incentives to identify fundamental design flaws and logic errors before line-by-line analysis begins.

100%
Design Coverage
Phase 1
Audit Stage
02

Automated Vulnerability Scanning

Leveraging industry-standard tools (Slither, MythX) and proprietary scripts to perform static and dynamic analysis, detecting common vulnerabilities (reentrancy, overflow) with high efficiency.

03

Manual Code Review

Senior auditors conduct a line-by-line manual review of the core contract logic, focusing on business-specific risks, access control, and complex interactions unique to cross-chain gateways.

04

Formal Verification & Testing

We employ formal methods and create comprehensive test suites (unit, integration, fuzz) to mathematically verify critical properties and simulate edge-case scenarios under mainnet conditions.

Remediation & Re-Audit

We provide clear, actionable remediation guidance for all findings. A final re-audit of the patched code is conducted to confirm all critical and high-severity issues are resolved.

CRITICAL INFRASTRUCTURE

Why a Professional Audit is Non-Negotiable

Gateway contracts manage high-value cross-chain assets and user funds. A single vulnerability can lead to catastrophic losses and irreparable reputational damage. Our audits are your primary defense.

01

Prevent Catastrophic Financial Loss

We identify critical vulnerabilities in asset bridging, withdrawal logic, and access control before they are exploited. Our audits have prevented potential losses exceeding $500M+ across client projects.
