freeze

A price lock for BTC and ETH, inside PayBox

Lock today's price. Decide later.

BTC dipped but payday is a week away? Freeze today's price for a small fee. If it rises, the gain is yours. If not, you only lose the fee.

How you use it

Just tell your agent.

Freeze is a plugin for PayBox, the wallet your AI agent can use. No new app, no exchange account. You talk, PayBox asks you to approve, the card lands in your wallet.

  1. Connect PayBox

    Add PayBox to Claude or ChatGPT. In Claude: Settings, Connectors, add https://api.paybox.sh/mcp.

  2. Turn on Freeze

    In PayBox, open Plugins and enable Freeze. Keep a few dollars of ETH on Arbitrum; Freeze swaps a little into USDC for the fee when needed.

  3. Say what you want

    "btc dipped today but payday is in 7 days, can you pull up my freeze plugin so i lock price for $20 btc" Approve in PayBox and you are done. If BTC rises, ask your agent to cash the card before it ends.

Why not just buy?

Because the money isn't here yet.

Buying $500 of BTC needs $500 today and carries every drop. A freeze needs only the fee, keeps the rise, and the fee is the most it can cost you.
