🧐 What Is This?

BNB Chain AI Toolkit gives AI assistants superpowers on the blockchain.

It's a single repository with everything you need to build AI-powered applications on BNB Chain — agents, blockchain connectors, market data, DeFi tools, wallets, and Web3 standards. All open source.

In plain English: Imagine giving Claude or ChatGPT a crypto wallet, a trading terminal, and 78 expert advisors. That's what this toolkit does.

> New to crypto or AI? Start with our [What Is This?](docs/what-is-this.md) guide — written for non-technical people.

Why This Toolkit?

| Problem | Solution | |---------|----------| | Fragmented BNB Chain tooling | Single repo with everything integrated | | AI can't interact with blockchains | 6 MCP servers give AI direct chain access | | Complex DeFi interactions | 78 specialized agents for every protocol | | Multi-chain complexity | Multi-chain support with unified interfaces | | No accessibility standards | W3AG + ERC-8004 for inclusive Web3 |
