POS Smart Contract Formal Verification

We translate your protocol's business logic into precise, machine-readable specifications using TLA+ or Coq. This creates a formal model that defines the exact intended behavior of your staking, slashing, and reward distribution mechanisms.

We define and prove critical safety and liveness properties. This includes verifying invariants like "total stake never exceeds total supply" and proving the absence of reentrancy, overflow, and logic flaws in your contract's core functions.

Our tools exhaustively explore all possible execution paths of your Solidity/Vyper code using symbolic execution (Manticore, MythX). This identifies edge cases and complex attack vectors that traditional testing misses.

We integrate findings with a manual security audit, providing a comprehensive report with mathematically proven guarantees. You receive actionable fixes and a certificate of verification for your stakeholders and users.

Our formal verification process mathematically proves the absence of critical bugs like reentrancy, overflow, and access control flaws before deployment. This eliminates the primary cause of catastrophic financial loss in DeFi.

Integrate formal verification into your CI/CD pipeline to catch logic errors in hours, not weeks. Reduce audit cycles by up to 60% and deploy with confidence, knowing your core contract logic is mathematically sound.

Provide verifiable, machine-checked proof of security to investors, partners, and regulators. Our formal verification reports serve as a gold-standard credential for institutional due diligence and compliance readiness.

Prevent expensive emergency patches, forks, and reputational damage from post-launch exploits. The upfront investment in formal verification is a fraction of the potential cost of a single security incident.

We begin by collaborating with your team to define formal specifications for your PoS protocol's critical properties: slashing conditions, validator lifecycle, and consensus invariants. This ensures the verification targets your exact business logic and security requirements.

Our experts translate your Solidity/Vyper code into a formal model using tools like K-Framework or Coq. We codify your security properties (e.g., "no double signing," "correct reward distribution") into machine-verifiable theorems.

We systematically prove or disprove each property against the formal model. Any violation is documented as a counter-example, providing a concrete, reproducible test case to guide remediation.

We provide actionable, line-by-line remediation reports for any vulnerabilities discovered, followed by re-verification of the corrected code. This cycle continues until all critical properties are formally proven.

Delivery of a comprehensive verification report and machine-checkable proof certificates. We provide integration guidance for your CI/CD pipeline to ensure future code changes maintain verified properties.

Our team holds PhDs in formal methods and has verified protocols securing over $5B+ in TVL. We focus exclusively on blockchain systems, providing deeper protocol expertise than general-purpose audit firms.
