Rain launched spending accounts for AI agents, called Agent Vaults

An AI agent that can order supplies or book a flight is still stuck at the checkout. Most agents route the payment through a human at a wallet app. Or through a third-party wallet that pulls the user out of the host product. Rain says it has a cleaner way.

Rain, a stablecoin card and payment infrastructure company, launched Agent Vaults this week. The Information first reported the launch. A vault is a spending account an AI agent owns inside a host app. People, businesses and other agents can fund it. The vault owner sets the rules. Every payment runs through what Rain calls the Agent Control Layer.

What the vault holds, and how money moves

Rain says a vault can be funded three ways. Bank transfer on instant rails where they exist. A card top-up for any amount the user picks. Or a stablecoin transfer from any wallet. The agent spends through scoped cards issued from the vault. Rain says the cards work at 175 million merchant locations.

The agent can also send value out. Rain lists two paths. One: a bank payout in local currency, in more than 80 countries. Two: a stablecoin transfer to another vault or any wallet.

The rules live on the card, not above it

The Agent Control Layer carries the limits. Rain says each scoped card is issued with five dials. The host platform or the end user sets them at issuance. How much, per purchase, per card, per day, week or month. Where, by merchant, category or anywhere. Until when. Who signs off, meaning which purchases wait for human approval. And a cap across the platform, on active cards and total spend.

Rain says the checks run at authorisation, on the card rail itself. So a purchase that breaks a rule fails at the card network before money moves. That is the part that is new. On fiat rails, limits and approvals sit outside the money, applied after an attempt and enforced by middle parties.

What a team building an AI product can do with this

Three audiences, by Rain's own description. A team building an agent product that wants to pay from inside its own app. A team that pays today through a third-party wallet and loses the user out to it. And a payments platform that already runs cards or wallets and wants to add agent flows.

A team in the first bucket gets the clearest answer. Instead of integrating a wallet that redirects the user, the team can offer a branded vault inside its product. Rain says the host platform keeps the user relationship, earns the interchange on each purchase, and names the statement line. The team does not have to become a regulated payments company to do it, because Rain holds that layer.

Two limits to keep in view. Every fact here is Rain's own. The per-card controls, the merchant count and the 80-country reach all wait on independent testing. And agentic commerce rules are still forming, so a host platform's compliance work does not disappear.
