Provides educational tools for using Coinbase Agentic Wallet and CDP facilitator, enabling agents to inspect wallets, configure wallet skills, and understand x402 payment signing commands for Coinbase-based wallets.
Provides educational tools for using Solana wallets, enabling agents to inspect balances, decode x402 challenges, and learn how to sign payments on the Solana blockchain.
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.
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.

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