The missing crypto toolbox for AI-assisted development on Mac.
One installer. One plugin. Full smart-contract lifecycle — scaffold, test, audit, deploy — without juggling ten repos and copy-pasted snippets.
Ship Solidity and Solana projects faster in Claude Code and OpenAI Codex. Crypto DevKit adds slash commands, chain playbooks, contract templates, and a native Apple Silicon bridge so your agent actually follows a proven Web3 workflow — not random guesses.
Works with Claude Code · OpenAI Codex · Claude Desktop · macOS Apple Silicon
Building on-chain software with AI is fast — until you need the boring parts right: Foundry layout, Anchor accounts, testnet RPCs, audit checklists, explorer verification. Most developers bounce between docs, gists, and half-finished ChatGPT threads.
Crypto DevKit fixes that. Install once on your Mac, run /crypto-devkit:setup, and your Claude or Codex session gets:
If you ship DeFi, memecoins, NFTs, or infra contracts and you code on a MacBook with Claude or Codex — this repo is for you.
| Layer | What you get |
|---|---|
| Claude Code plugin | 9 slash commands for the full contract lifecycle |
| Codex-friendly skills | Same workflows usable in Codex CLI & Claude Code sessions |
| Templates | ERC20 Solidity, Anchor lib.rs, deploy scripts |
| Chain guides | Ethereum, Base, Solana (+ RPC presets) |
| Skills | Foundry, Anchor, audit rule packs |
| macOS native bridge | arm64 helper — auto-starts on install |
| Installer | install.sh / install.command → ~/.crypto-devkit |
macOS only · Apple Silicon (M1–M4) · Claude Code or Codex
| Command | Action |
|---|---|
/crypto-devkit:setup | Initialize kit & chain registry |
/crypto-devkit:new-evm | Scaffold Foundry / ERC20 contract |
/crypto-devkit:new-solana | Scaffold Anchor program |
/crypto-devkit:test | forge test or anchor test |
/crypto-devkit:deploy-testnet | Guided testnet deploy (Base, ETH, Arb…) |
/crypto-devkit:audit | Security checklist → AUDIT.md |
/crypto-devkit:rpc | RPC / chain ID reference |
/crypto-devkit:verify-explorer | Etherscan / Basescan verify |
Guides install to ~/.crypto-devkit/chains/ on setup.

Stars on GitHub
Helps you take a change from a rough idea or bug report through to a tested, reviewed result, with each step handled by a focused skill. Its skills cover pinning down domain terms, designing module interfaces, diagnosing hard bugs, and reviewing changes against your repo's coding standards.
@mattpocockA development methodology for coding agents that makes the agent brainstorm before building, follow plans, run parallel work and finish branches in a disciplined way. You get fewer skipped steps and more consistent results from your coding assistant.
@obraGives your coding agent a planning, testing and review routine to follow on every task. It plans before building, checks changes with tests, has a fresh reviewer look for regressions, and saves repeated wins as reusable skills.
@affaan-mDeveloper tools for working on the React codebase itself. Provides skills for extracting error messages, managing and debugging feature flags across release channels, running Flow type checks, and fixing lint and formatting issues before committing.
@facebookA Claude Code plugin for smart contract development on Solana with Anchor and on EVM chains with Foundry. It covers scaffolding, building and testing, auditing, and deploying contracts. Install it with the command on its page. It includes anchor, audit, foundry. Its skills do not fire on their own yet. Free and open source.
