Nod: give your AI an allowance

Nod is a Stellar wallet you add to Claude. Give each AI app an allowance, such as 5 USDC until tomorrow, and it pays for APIs and pays people on its own. Anything bigger comes to you, and one passkey tap approves that exact payment. The allowance is an OpenZeppelin spending-limit policy on your Stellar account, not a setting on our server. Stellar testnet. Built at HackMeridian 2026.
