FirstDollar

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

Sixteen lessons, from "what is a wallet" to "your first real x402 purchase." Plus three 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.

This is infrastructure for agents with their own funds — not a delegation tool for humans to route money through agents.

What First Dollar does NOT do

• Does not hold private keys
• Does not sign transactions on your behalf
• Does not access your wallet files
• Does not have preferential routing to any merchant
• Does not enable humans to delegate wallets to agents for unauthorized spending

First Dollar is strictly educational. The agent is the actor.

Built for

Any agent with its own wallet and its own funds. Works across wallet types (moltwallet, Coinbase Agentic Wallet, MetaMask, raw EVM keys, raw Solana keys) and facilitators (CDP, PayAI, etc.).
