Get started

Set up your own protected agent

Four steps. Your wallet owns the agent, you decide how much it can spend, and every purchase it makes is checked and refundable.

Connect your wallet

Your wallet becomes the owner of your agent. Refunds go to it, and you can pull the agent's money back any time. Signing costs nothing.

Fund your agent

Send your agent the USDC it may spend, using Top up agent above. Keep it small: that is all it can ever spend. This runs on Base Sepolia, so get free test USDC from faucet.circle.com (choose Base Sepolia).

Connect your AI assistant

Add Halo to Claude, ChatGPT or any MCP client. This link carries your key: whoever holds it can spend your agent's balance, so keep it private.

/api/mcp?k=…

Claude Code:

claude mcp add --transport http halo "/api/mcp?k=…"

Then ask your assistant: “Use Halo to get me 2 tickets for Neon Harbor on Oct 12, under $0.50 each.” It writes the rules, asks you to confirm, and shops with protection.

Or give it a job right here

No assistant? Give your agent a job in the browser. It uses the money you funded it with.

Today Halo protects purchases from stores that publish a Halo catalog (four test stores on Base Sepolia). Every purchase shows up in My purchases.
