The economic layer for AI agents

One identity. One wallet. Every wall. We authorize the payment — and never touch the money.

how it works

The wall, already live

A wall we built gates a site on an agent’s identity. No signup, no login — a signed header is the key. Unsigned, it’s a 402.

We issue the key — identity + authorization. The money flows person → site. We never hold it.

$ curl https://wall.mothershy.com/ -H "X-MotherShy: <signed envelope>"

rails

One agent, every rail

MotherShy speaks whatever the site already speaks. We own the agent side — verification is a commodity; the network is the moat.

HTTP 402 · USDC

The open machine-payment standard. Coinbase → Linux Foundation, production.

MPP

Cards + stablecoins

Machine Payments Protocol. Backwards-compatible with x402.

Design-compatible, closed beta. A follow-on rail, not a gate.

scoped keys

On-behalf spend

A budget-capped key any agent can hold. The swarm mechanic.

the line

We authorize. We never hold.

MotherShy mints the key — who the agent is, what it may spend. The money flows person → site on the site’s own rail. We never touch it, so we carry none of a money handler’s KYC weight.

what we own

The key

Identity + authorization. A signed capability: “this agent may spend up to $X.” It carries no value itself — it opens the door.

what we never own

The money

Always external. It flows person → site on the rail the site already uses. We don’t receive it, hold it, or pass it.
