# ScopeBots

> ScopeBots (https://scopebots.ai): Find the right tools to build on Web3. A directory of Web3 developer tools (infrastructure, smart contracts, AI agents, security, wallets, data and gaming). Each tool has a short verdict, price, and the chains its maker's own docs name (mainnet or testnet), each with a link to the page it was checked against. Last updated 2026-10-15. Not financial or investment advice. Chain support is what each maker's own docs say, not an audit, endorsement or security review. Sponsored placements are labeled and do not affect verdicts.
