Payment Settlement Audit and Security Review

Comprehensive smart contract and system audits by blockchain security experts to ensure the integrity and safety of your tokenized payment settlement logic before launch.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3 veterans for your protocol's foundation.

We architect and deploy audit-ready smart contracts that power your core business logic. Our development process is built on Solidity 0.8+ with OpenZeppelin standards, ensuring security and gas efficiency from day one.

We deliver a fully tested, documented, and deployable contract suite in as little as 2 weeks for an MVP.

Our full-service development includes:

  • Custom Logic: Tailored ERC-20, ERC-721, ERC-1155, or bespoke contract systems.
  • Security-First Approach: Integration of industry patterns like checks-effects-interactions and reentrancy guards.
  • Gas Optimization: Code reviews focused on minimizing transaction costs for end-users.
  • Upgradeability Strategy: Implementation of transparent proxy patterns (UUPS) for future-proofing.

We provide more than code. You receive a comprehensive delivery package with deployment scripts, technical documentation, and a security review summary, enabling your team to launch with confidence.

PROVEN FRAMEWORK

Our Comprehensive Audit Methodology

Our multi-layered, process-driven approach ensures no vulnerability goes undetected, delivering a security posture that protects your assets and builds user trust.

01

Manual Code Review

Senior auditors perform line-by-line analysis of your smart contracts and off-chain settlement logic, identifying complex vulnerabilities automated tools miss.

02

Automated Vulnerability Scanning

We run a suite of industry-standard tools (Slither, MythX) and proprietary scripts to detect common flaws, reentrancy risks, and gas inefficiencies systematically.

Architecture & Design Analysis

We assess the overall system design, tokenomics, access controls, and upgrade mechanisms for logical flaws and centralization risks before a single line is audited.

Formal Verification

For critical payment logic, we apply mathematical proofs to verify contract behavior matches specifications, guaranteeing correctness for core settlement functions.

BEYOND STANDARD SECURITY

Why a Specialized Settlement Audit is Critical

Generic smart contract audits miss the complex financial logic and state transitions unique to payment settlement systems. Our targeted review ensures your protocol's core value transfer is secure, compliant, and economically sound.

Frequently Asked Questions

Get clear answers about our audit process, timeline, and how we secure your payment infrastructure.

We follow a rigorous, multi-layered methodology based on industry standards like NIST and OWASP. Our process includes: 1) Architecture Review (smart contract logic, oracle integration, off-chain components), 2) Code Review (Solidity/Vyper security patterns, gas optimization, reentrancy checks), 3) Functional Testing (settlement finality, fee calculation, dispute resolution), and 4) Economic Security Analysis (liquidity risks, incentive misalignment, oracle manipulation). We've applied this to secure over $500M+ in transaction volume.
