Pentagonal

AI-powered smart contract forge with an 8-agent adversarial security audit system.

Generate, audit, fix, and compile Solidity and Anchor/Rust contracts across 8 chains including Ethereum, Base, Polygon, Arbitrum, Optimism, BSC, Avalanche, and Solana. Includes token intelligence lookups with market data, holder analysis, and honeypot detection. Self-learning security rules engine that improves with every audit.
