Gives Claude wallet operations across EVM chains and Solana without leaving the MCP interface. You get 29 tools: create wallets, send ETH or SOL, transfer ERC-20 and SPL tokens, approve token spending, wrap native assets, and handle x402 micropayments. Built-in guards limit daily spending and gas prices. The setup is three environment variables (username, API key, optional wallet ID for auto-pay). Works on Ethereum, Base, Polygon, Arbitrum, Optimism, Avalanche, and Solana mainnet plus devnet. No KYC or credit card required. Pay 0.00345 dollars per operation with USDC on-chain after 6,000 free monthly operations. Pair it with guessmarket-mcp to trade prediction markets or use the paywall tools to accept crypto payments for your own APIs.
