Rain Agent Vaults let AI agents receive, spend and send money on Base

What Base and Rain announced

Base told its followers on 10 November 2026 that "every agent needs a wallet" and that AI agents can now receive, spend and send money on Base with Rain Agent Vaults. Its post quotes Rain, a company that builds stablecoin-powered card and payment infrastructure for other businesses, which launched the product a minute earlier with a short video and the line "Your agent. Your brand. Your customers and economics."

Rain's launch post describes an Agent Vault as a secure place inside an application where an AI agent can receive funds, make purchases and send payments on behalf of a person or a business. The vault can belong to the user or to the platform, and the company that embeds it keeps its own brand on the experience. Base's post is what ties the launch to the Base network; Rain's own pages speak more generally of support for major blockchains and stablecoins and do not name individual networks or tokens.

Money in, money out

A vault can be topped up by bank transfer, by card or with stablecoins sent from any wallet, and agents can also be paid directly by people, businesses and other agents for work they do. Funds are held either as stablecoins in an embedded wallet or as fiat in a bank account, depending on how the company sets it up.

On the way out, Rain lists three rails. Agents can pay at more than 175 million merchant locations with scoped Visa or Mastercard cards, send bank payouts in local currency to more than 80 countries across 50 currencies, and transfer stablecoins to people, businesses or another agent's vault. Because purchases run over the card networks, Rain notes that shops do not have to accept stablecoins to be paid by an agent.

Rules the agent has to follow

The controls sit in what Rain calls the Agent Control Layer. The vault owner decides how much an agent may spend per purchase, per card or per day, week or month, where it may spend, whether a single merchant or a category such as travel, how long a card stays valid, and which purchases must wait for a person to approve. Platforms can also cap the number of active cards and total spend across all their vaults. For cards, Rain enforces these limits at authorisation; bank payouts and stablecoin transfers can be limited to approved recipients and amounts.

Rain says the vaults are designed to work with Visa Intelligent Commerce and Mastercard Agent Pay, the card networks' own agent payment programmes, with wallets secured by Turnkey and card tokenisation handled by Basis Theory.

Built for companies, not for end users

Agent Vaults are not something an individual can open today. Rain is selling them to AI-native apps that want their agents to pay for things, to apps that currently send users out to a third-party wallet to approve each payment, and to banks, fintechs and payment platforms that want to add agent payments to products they already run. Rain's pitch is commercial: the platform's name appears on card statements, card spending earns it interchange, and it sets its own fees on payouts and incoming payments.

Rain has not published prices, launch customers or a list of countries for this product. Its site also states that Rain is a financial technology company, not a bank, exchange or custodian, and does not hold deposits.

Our take

This is another sign that agent payments on Base are moving from demos to products, after Mastercard's Agent Pay for Machines pilot settled on Base in October. The interesting part is the control layer: budgets, merchant limits and approvals are what make it reasonable to let software spend money at all. For now this matters to developers more than to everyday users, who will only meet it inside apps that adopt it. If you want to hold stablecoins and use Base yourself in the meantime, the Base app and Phantom, both linked on this page, are self-custody wallets that work with the Base network.
