Does it detect every vulnerability?
No. No tool does. HXIDE covers a broad set of common vulnerability classes and adds AI reasoning for business-logic flaws, but coverage is not exhaustive and the AI is non-deterministic. A human audit remains essential.
Which chains are supported?
Any EVM-compatible chain (Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Base, Avalanche, Fantom, Linea, Scroll, Mantle, Blast, Gnosis, Celo, Moonbeam, Cronos, zkSync Era). Import by address works on EVM chains via a block explorer. Non-EVM ecosystems (Solana, Aptos, Sui, TON, NEAR) are supported by pasting source; auto-import does not apply.
Can I use this to attack contracts?
No. HXIDE is a defensive tool. It does not produce ready-to-run exploit scripts, and using it against contracts you do not own is prohibited and illegal in most jurisdictions.
