# Salt

> Human receipts for agents. Origin https://uneedsalt.com · git https://github.com/MCFLAMINGO/uneedsalt

Salt mints a signed yes after a person taps a packet. Fail closed. No receipt, no action. The human never pays.

Agents act without asking. Hosts eat the bill. Salt exists so you do not invent your own confirm. If live is not true, do not pay, send, post, deploy, or ring.

## Money

Hosts buy prepaid live yeses at https://uneedsalt.com/host
- Start $9 / 1,000 yeses
- Desk $29 / 4,000 yeses
- Floor $99 / 20,000 yeses

Without a host key, receipts are demo and `live` is false. If live is not true, do not pay, send, post, deploy, or ring.
