Pentagonal
OfficialPentagonal is an AI-powered smart contract security and development platform supporting multiple blockchains (Ethereum, Base, Polygon, Arbitrum, Optimism, BSC, Avalanche, Solana).
pentagonal_generate— Create production-quality smart contracts from natural language descriptions for EVM (Solidity) and Solana (Anchor/Rust or SPL Token), with built-in security rules.pentagonal_audit— Run an 8-agent security pen test covering reentrancy, flash loans, access control, oracle manipulation, front-running, and more — with severity ratings, line numbers, and PoC exploits.pentagonal_fix— Automatically patch a specific vulnerability while preserving all existing functionality.pentagonal_compile— Compile Solidity source code to obtain ABI, bytecode, constructor arguments, and gas estimates.pentagonal_lookup— Retrieve a full intelligence report on any token or contract address: price, market cap, holders, liquidity, LP lock status, honeypot/security flags, and verified source code.pentagonal_rules— Access the self-learning security rules accumulated from all past audits.pentagonal_chains— List all supported blockchains with chain IDs, explorer URLs, and deployment hints.
Provides tools for generating, auditing, fixing, and compiling Solidity smart contracts on the Ethereum blockchain, including security analysis and token intelligence lookups.
Provides tools for generating, auditing, fixing, and compiling Solidity smart contracts on the Optimism blockchain, including security analysis and token intelligence lookups.
Provides tools for generating, auditing, fixing, and compiling Solidity smart contracts on the Polygon blockchain, including security analysis and token intelligence lookups.
Provides tools for generating, auditing, fixing, and compiling Anchor/Rust smart contracts for Solana blockchain deployment, including security analysis and functionality preservation.
