Rain launches Agent Vaults, embedded accounts for AI agent payments

A vault can be funded by bank transfer, by card or with stablecoins[1]. An agent can also be paid directly by people, businesses and other agents, for services it performs, rather than only from money its user puts in[1]. The product page says a bank transfer lands on instant rails where those rails are available, a card top-up is for an amount the user chooses, and stablecoins can come from any wallet. Users can add US dollars, Mexican pesos, euros and other currencies[2]. The Paypers reports bank funding that includes ACH, Fedwire, FedNow, SEPA and FPS[3].

Rain says funds can be held as stablecoins in an embedded wallet or as fiat in a bank account, and that the partner chooses the structure[1]. The Paypers reports that a user funding by bank transfer or card does not have to buy stablecoins: the balance is held as stablecoins in a non-custodial wallet, and Rain settles with the card networks in stablecoins[3].

Once the vault is funded, Rain lists three ways out. An agent can pay with a scoped Visa or Mastercard card at more than 175 million merchant locations, send a bank payout in local currency to more than 80 countries in 50 currencies, or transfer stablecoins to a person, a business or another agent[1]. The product page says a stablecoin transfer can go to another agent's vault or to any wallet, and that it moves onchain, in seconds. It also says the card pays only with what is already in the vault, and that the vault is funded before the card pays[2]. The Paypers puts the card acceptance at 175 million merchant locations across 200 countries and territories, and says the agent can only spend or transfer what the vault holds[3].

Rain's Agent Control Layer is where a platform or a user sets how much an agent can spend, which merchants it can pay, and when a payment is allowed[1]. On cards, those limits are written into scoped cards, and Rain enforces them at authorisation[1]. The product page lists the levers: an amount per purchase, per card, per day, week or month; one merchant, a category such as travel or software, or anywhere; how long it lasts (an hour, a trip, a month or a single purchase); which purchases wait for a person; and caps on active cards and on total spend across every vault on the platform[2].

The Paypers says agents pay with a virtual Visa or Mastercard issued for a task, with the amount, merchant and expiry fixed at issuance, so the agent cannot raise its own limit. A single-use card stops after one approved purchase, and the merchant does not have to change its checkout[3]. Rain's post gives its own example: a business could allow one supplier, up to an approved amount, before an expiry date[1]. Partners can also limit bank payouts and stablecoin transfers to approved recipients and amounts[1][2].

The Paypers reports an example Rain used to illustrate the model. A bakery owner funds a vault with US$5,000, allows the agent to pay suppliers only, and requires approval above US$1,500. Supplier purchases of US$640 and US$800 go through. A US$2,400 equipment purchase is held, because equipment falls outside the rules[3].

Rain says Agent Vaults are designed to support Visa Intelligent Commerce and Mastercard Agent Pay, alongside major blockchains and stablecoins. Wallets are secured by Turnkey, and card tokenisation is supported by Basis Theory[1]. The product page says Rain is a Visa and Mastercard Principal Member, so one integration can offer payments to users in more than 80 markets, and that Rain can generate network agentic tokens that show a merchant an agent is paying with the user's permission[2]. The Paypers says Rain is enabling its programmes for those two network products, and that scoped cards will carry the networks' agent credential, which signals the user's consent to the merchant and the issuer alongside the partner's rules[3].

Rain's own pages do not name a blockchain or a stablecoin. Exchange News reports that Base posted on 10 November that "every agent needs a wallet", and that agents can now receive, spend and send money on Base with Agent Vaults. It says Base's post is what ties the launch to that network[4].

Rain is offering Agent Vaults to companies that embed them. It names three: AI applications that want their agents to pay inside the product, applications that today send users out to a third-party wallet, and banks, fintechs and payment platforms adding agent payments to products they already run[1][2]. Exchange News says an individual cannot open an Agent Vault today[4].

Users sign up with the platform, the platform controls the approval, and its name can appear on card statements for purchases through its card programme. Card purchases can generate interchange for the platform. Payouts and incoming payments can generate fees the platform sets. Rain says it handles the infrastructure underneath and does not appear to the end user[1][2]. The product page says cards are issued by API, with the limits set in the same call, and that partners get a dashboard, a sandbox, and real-time notifications for balance, authorisation and decline events[2].

The Paypers says Rain is working with agent developers, marketplaces and payment platforms, and does not name them[3]. Exchange News says Rain has not published pricing or named launch customers[4].

Rain's pitch is that an agent can pay a merchant that already takes cards, from a balance inside the app that owns the customer, with the limit checked when the card is authorised[1]. With a third-party wallet, Rain says, the user may have to leave the app to approve a payment, the wallet's name can appear on the statement, and the wallet keeps the revenue[1].

Rain's public pages still do not give a developer a price, a named customer or a named stablecoin[4]. The only chain named in these reports is Base, which Exchange News attributes to Base's post[4].
