Smart Contract Formal Verification

Service Overview

Runtime Verification provides formal verification services for smart contracts using the K Framework. By verifying at bytecode level, the service provides mathematically proven guarantees of contract correctness, detecting issues that traditional audits miss.

Core Service Components

K Framework Verification

Symbolic Execution: Exhaustive path exploration using symbolic values.

SMT Solver Integration: Z3 solver for mathematical constraint solving.

Bytecode Analysis: Verification at EVM bytecode level.

Security Analysis

Vulnerability Detection: Integer overflow/underflow, re-entrancy, gas issues.

VM-Level Exploits: Stack limits, gas calculations, compiler bugs.

Formal Specifications: Mechanized specifications for contract behavior.

Developer Support

Solidity-Based Proofs: Write proofs in familiar Solidity syntax.

Training: Team education on formal methods.

Specification Development: Help defining formal specifications.
