Smart Contract Formal Verification

Apply mathematical methods to prove the correctness of your protocol's core logic against a formal specification. Eliminate entire classes of bugs and achieve the highest level of security assurance.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

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

We architect and deploy custom Solidity and Rust contracts with formal verification and OpenZeppelin security patterns. Our process includes threat modeling, gas optimization, and comprehensive unit/integration testing to ensure zero critical vulnerabilities before mainnet deployment.

  • Custom Logic: DEX/AMMs, NFT marketplaces, token vesting, governance systems.
  • Security First: Multi-signature deployment, upgradeable proxy patterns, and third-party audit preparation.
  • Guaranteed Outcomes: 99.9% uptime SLA, gas costs optimized by 30-50%, and deployment readiness in 2-4 weeks.

PROVEN PROCESS

Our Formal Verification Methodology

Our systematic, multi-stage approach ensures your smart contracts are mathematically proven to be correct, secure, and free from critical vulnerabilities before deployment.

01

Specification & Property Definition

We translate your business logic into formal, machine-readable specifications. This critical first step defines the exact, provable properties your contract must uphold, eliminating ambiguity.

Logic Coverage
TLA+ / Coq
Spec Languages
02

Model Checking & Theorem Proving

Using tools like Certora Prover and K-Framework, we exhaustively verify your contract's bytecode against the formal specifications, proving correctness across all possible execution paths.

Exhaustive
State Space Analysis
Certora
Industry Standard
03

Invariant Verification

We identify and prove critical system invariants—properties that must always hold (e.g., "total supply is constant"). This prevents entire classes of exploits like reentrancy and arithmetic overflow.

Automated Symbolic Execution

Our tools symbolically execute contract code, exploring all potential inputs and states to uncover edge cases and vulnerabilities that traditional testing misses.

PROVEN RESULTS

Business Outcomes of Formal Verification

Formal verification is more than a security audit; it's a strategic investment that delivers measurable business value. We translate mathematical rigor into tangible outcomes for your project and your bottom line.

01

Eliminate Critical Vulnerabilities

We mathematically prove the absence of entire classes of bugs (reentrancy, overflow, logic flaws) before deployment. This prevents catastrophic losses and protects your project's treasury and user funds from exploits that automated tools miss.

Accelerate Time-to-Market

Integrate formal verification into your CI/CD pipeline to catch logic errors during development, not in production. This reduces costly rework cycles and audit delays, allowing you to deploy complex DeFi protocols and dApps with confidence, faster.

Reduce Long-Term Security Costs

A single, comprehensive formal verification report replaces multiple iterative manual audits. This upfront investment significantly lowers the total cost of security over your protocol's lifecycle by preventing post-launch emergency patches and reputation-damaging incidents.

Ensure Regulatory Compliance Readiness

For projects in regulated spaces like RWA tokenization or institutional DeFi, formal verification provides the highest standard of evidence for code correctness. It demonstrates due diligence and a proactive security posture to regulators and institutional partners.

Future-Proof Protocol Upgrades

Formal specifications act as a single source of truth for your protocol's intended behavior. This ensures all future upgrades and optimizations are provably safe and consistent with the original design, preventing governance disputes and upgrade failures.

METHODICAL & TRANSPARENT

Our Formal Verification Process

A rigorous, four-phase methodology designed to deliver mathematically proven security for your smart contracts, ensuring they behave exactly as intended.

01

1. Specification & Scoping

We collaborate with your team to define formal specifications—the precise mathematical properties your contract must satisfy. This includes functional correctness, security invariants, and business logic requirements.

2. Model Building & Theorem Proving

Our experts translate your Solidity/Vyper code into a formal model using tools like K Framework or Coq. We then prove core security theorems (e.g., no reentrancy, correct access control) against the specifications.

Formal Verification FAQs

Get clear answers to the most common questions about our rigorous, mathematically-proven approach to smart contract security.

Our standard engagement for a core protocol module (e.g., a token vault, AMM math library, or staking contract) takes 3-6 weeks. This includes specification writing, verification, and final reporting. Complex, multi-contract systems can take 8-12 weeks. We provide a detailed project plan with milestones before any work begins.
