Fraud Proof Formal Verification & Audit

Rigorous mathematical verification and security auditing of fraud proof system designs and implementations to eliminate logical flaws, ensure correctness of state transitions, and provide assurance for institutional clients.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts on EVM and Solana that power your core business logic. Our focus is on security-first development, gas optimization, and regulatory compliance from day one.

We deliver battle-tested contracts with a 100% audit pass rate for our clients.

  • Security Audits: Every contract undergoes rigorous review using Slither, MythX, and manual expert analysis.
  • Gas Efficiency: Optimized for cost, reducing user transaction fees by up to 40%.
  • Compliance Ready: Built-in patterns for ERC-20, ERC-721, and custom standards with upgradeability via OpenZeppelin.
  • Full Lifecycle Support: From initial design and testing to deployment on Mainnet and ongoing maintenance.

PROVEN FRAMEWORK

Our Formal Verification & Audit Methodology

A rigorous, multi-layered process designed to eliminate vulnerabilities and provide mathematical proof of correctness for your smart contracts and fraud proof systems.

01

Specification & Threat Modeling

We begin by formally defining the intended behavior and security properties of your system. This includes identifying potential attack vectors and establishing a verifiable baseline, ensuring our audit targets the most critical business logic.

02

Automated Symbolic Execution

Leveraging tools like Manticore and Slither, we systematically explore all possible execution paths. This uncovers edge cases and logic flaws that traditional testing misses, providing >95% path coverage for core functions.

03

Manual Expert Review

Our senior auditors conduct line-by-line analysis of the codebase, focusing on protocol-specific risks, economic incentives, and integration points. This human expertise catches complex vulnerabilities automated tools cannot.

04

Formal Verification with TLA+/Coq

For critical consensus mechanisms and fraud proof logic, we apply formal methods to mathematically prove the system behaves as specified. This provides the highest level of assurance for components securing high-value assets.

05

Remediation & Re-verification

We provide clear, actionable fixes for all identified issues and formally re-verify the corrected code. Our process includes a final security sign-off, ensuring no regression vulnerabilities are introduced.

06

Comprehensive Audit Report

You receive a detailed report with severity-graded findings, proof-of-concept exploits, and remediation guidance. The report serves as a trust signal for your users, investors, and integration partners.

TANGIBLE ROI

Business Outcomes: Beyond Technical Correctness

Formal verification and audits are technical necessities, but their true value is measured in business results. We deliver verified security that directly protects your assets, reputation, and bottom line.

01

Prevent Financial Loss

Our formal verification mathematically proves the absence of critical vulnerabilities, directly protecting the assets your protocol manages. This is your first line of defense against exploits that can drain millions.

STRUCTURED FOR SECURITY

Our Phased Engagement Process

A rigorous, multi-stage methodology designed to systematically eliminate vulnerabilities and deliver mathematically provable security for your smart contracts and fraud-proof systems.

01

Phase 1: Architecture & Specification Review

We conduct a deep-dive analysis of your system's architecture and formalize its intended behavior into machine-readable specifications. This critical first step ensures our verification targets the correct logic and prevents misaligned audits.

Deliverable: Comprehensive specification document and threat model.
