ChainGPT Claude Skill & Plugin — Developer Kit for Claude Code

Updated May 30, 2026, 09:38 AM

ChainGPT's Claude Skill (the ChainGPT Developer Kit for Claude Code) turns Claude into a Web3 engineering co-pilot. One install adds 129 MCP tools to Claude Code, custody-free.

What it gives you

  • ChainGPT AI products: chat, AI NFT generation, smart-contract generation, smart-contract audit, AI news.
  • DEX trading (EVM + Solana): OpenOcean, 1inch v6, CoW, Jupiter.
  • DeFi: Aave V3, Lido, EigenLayer, Pendle, Morpho, Marginfi, Kamino.
  • Perps: Hyperliquid and Drift. Prediction markets: Polymarket. Bridging: Across.
  • x402 agentic payments, Base (Basenames + Mini App scaffolding), ERC-8004 trustless-agent identity, multi-protocol portfolio, strategy persistence + backtest, and an agent wallet with a localhost admin dashboard plus a prompt-injection-resistant policy gate.
  • 45+ audited Solidity patterns, 10 project templates, daily live-API smoke tests.

Install (about 5 minutes)

  1. Install Claude Code — Anthropic's official CLI. Get the installer from claude.ai (macOS/Linux) or download it from code.claude.com/download (Windows), then confirm the install by running "claude --version".
  2. Add the ChainGPT marketplace — inside Claude Code, run the slash command: /plugin marketplace add ChainGPT-org/chaingpt-claude-skill
  3. Install the plugin — run: /plugin install chaingpt@chaingpt-claude-skill (or choose it from the /plugin picker).
  4. Reload — run /reload-plugins (or restart Claude Code). This registers 22 sub-skills and 129 MCP tools.
  5. Set your API key (recommended) — set the CHAINGPT_API_KEY environment variable to a key from app.chaingpt.org (API Dashboard). Without it the dashboard and on-chain tools still work; only the ChainGPT product tools (chat, NFT, audit, news) need credits. 1,000 credits = $10 (15% bonus when paying in $CGPT).

Using Solana DeFi tools? Set the SOLANA_RPC_URL environment variable to a real RPC (Helius, Triton, or QuickNode) — the public endpoint rate-limits.

Security model

Custody-free: the kit never holds your funds. On-chain actions are built as transactions you sign; the optional agent wallet runs locally behind a prompt-injection-resistant policy gate with a localhost admin dashboard. MIT-licensed and open source.
