VeriPro: Formal Verification for Smart Contracts

Executive Summary

VeriPro is a formal verification platform that mathematically proves smart contracts are secure before deployment. Unlike traditional testing that checks specific inputs, VeriPro uses symbolic execution to verify correctness for ALL possible inputs—eliminating entire classes of vulnerabilities that have caused billions in losses.

Built on Mantle Network, VeriPro provides developers with an intuitive interface to write specifications, run verification, and publish cryptographic attestations on-chain—creating a new standard for smart contract security.

The Problem

Smart Contract Vulnerabilities Are Catastrophic

Total losses exceed $10 billion since 2016.

Why Traditional Security Fails

1. Manual Audits Are Limited

   • Auditors review code manually

   • Can miss edge cases and complex interactions

   • Expensive (50K−50K−500K per audit)

   • Time-consuming (weeks to months)

   • No guarantee of completeness

2. Testing Is Incomplete

   • Only checks inputs you think of

   • Cannot cover all possible states

   • Hackers find the paths you don't test

   • 100% code coverage ≠ 100% security

3. Fuzzing Is Probabilistic

   • Random inputs may never hit edge cases

   • No mathematical guarantee

   • Time-limited exploration

The Gap

There's no accessible way for developers to mathematically prove their contracts are correct. Formal verification exists but is:

• Expensive (specialized consultants)

• Complex (requires PhD-level expertise)

• Slow (weeks of manual work)

• Inaccessible (no self-service tools)

The Solution: VeriPro

VeriPro democratizes formal verification by providing:

1. Intuitive Specification Language

Write properties in familiar Solidity syntax:

contract TokenTest is Test {
    function test_transferPreservesSupply(
        address from, 
        address to, 
        uint256 amount
    ) public {
        uint256 supplyBefore = token.totalSupply();
        
        vm.prank(from);
        token.transfer(to, amount);
        
        // This is verified for ALL possible values
        assertEq(token.totalSupply(), supplyBefore);
    }
}

2. Powerful Symbolic Execution Engine

• CBSE (Complete Blockchain Symbolic Executor): Rust-based engine using Z3 SMT solver

• Explores all execution paths automatically

• Finds counterexamples when properties fail

• 10x faster than existing tools

3. On-Chain Attestations

• Cryptographically signed verification proofs

• Recorded on Mantle blockchain

• Immutable evidence of security

• Verifiable by anyone

4. AI-Powered Specification Generation

• Gemini AI analyzes contracts

• Suggests properties to verify

• Reduces barrier to entry

• Accelerates adoption
