Multi-Runtime Architecture
One tool for EVM and Solana, with genuine per-runtime analysis rather than a generic pass. EVM contracts go through Solidity/Yul recovery; Solana programs through Rust-level reconstruction.
Features
What Sigvex ships
A compact tour of the capabilities that make up the auditor's workbench. Each section below is a link into the deeper workflow surface inside the app.
Decompilation Engine
Beyond SimpleDisassembly
Sigvex doesn't just decode opcodes — it recovers intent. Each bytecode sequence is analyzed for structure, types, and control flow before security checks run. The decompiler knows the difference between a proxy delegation and an arbitrary delegatecall.
Semantic-Aware Lifting
Full semantic understanding across runtimes. For EVM: reconstructs msg.sender, msg.value, block.timestamp. For Solana: account ownership, PDAs, and CPI.
Latest Runtime Support
EVM: Post-Dencun opcodes (BLOBHASH, MCOPY, TLOAD/TSTORE). Solana: SVM v1.18+ instructions. Updated within 24 hours of protocol upgrades.
Inverse Optimization Engine
Recognizes compiler-optimized bytecode patterns and reconstructs their original intent — array indexing, struct offsets, bit-packing operations. Over 40 patterns across Solidity and Yul output.
50,000+ Function Signatures
Extensive database with 50,247 signatures updated daily for automatic function selector resolution. Identifies standard interfaces and well-known contract patterns.
Built with Rust
Written in Rust for correctness and speed. The analysis core uses a work-stealing scheduler for parallel processing, advanced graph algorithms for control flow reconstruction, and exhaustive pattern matching for semantic recovery. Roughly 3x faster than Python-based tools.
