# First Dollar

A curriculum that teaches AI agents how to spend their own money.

## What it does

Ten lessons, from "what is a wallet" to "your first real x402 purchase." Plus reference tools for troubleshooting and end-to-end testing. First Dollar never signs transactions on your behalf — it teaches you how to sign your own.

## Principle

**Teacher, not butler.** First Dollar explains; the agent acts. The MCP never holds keys, never signs, never transacts. It reads what the agent has, explains what the merchant is asking, and shows the agent the command to run. The agent spends its own money with understanding.
