Problem Statement

No standard exists for AI agents to programmatically discover and invoke crypto wallet functions. MCP is server-based — private keys must leave the client process, breaking the non-custodial model. EIP-1193 and WalletConnect require UI popups — incompatible with AI automation. Framework tools (LangChain, CrewAI) are vendor-locked and non-portable. The result is fragmentation: every AI application that needs wallet functionality builds custom integration from scratch, and wallet developers have no standard to target for AI compatibility. CWP solves the N×M problem — wallet developers build one module, AI developers support one runtime.

This project contains two things: 1. The CWP Standard — a universal interface specification for AI applications to discover and use crypto wallets as in-process JavaScript modules. Defines the manifest schema, runtime interface, and security model. 2. A Reference Implementation — a chat-based AI wallet agent that demonstrates the standard with real on-chain execution on Ethereum and Base Sepolia testnets. The chat UI is one possible frontend built on the standard. Any AI application — CLI agent, browser extension, mobile app, multi-agent system — can implement the CWP runtime and use the same wallet modules. Private keys never leave the host process. Core features of the standard: - Manifest-driven tool discovery — drop a folder with manifest.json + index.js, auto-discovered - LLM-neutral schema — manifests convert to OpenAI/Claude/Gemini format at runtime - riskLevel enforcement — high-risk actions (sendETH, swap execute) always pause for user confirmation - Secure by default — single-module session, single-turn conversation, opt-out only with user consent - Chain-agnostic — EVM reference modules included, any chain (Solana, Sui, etc.) can be added Reference modules: Ethereum Wallet (8 actions), Base Wallet (9 actions), Uniswap V3 Swap (3 actions) Live demo with real on-chain execution on Ethereum Sepolia and Base Sepolia testnets.
