Rain has launched Agent Vaults, a payments product that lets AI agents collect and spend money within authorized limits. According to Foresight News, businesses can use their own branding to embed payment functions in applications, allowing agents to collect funds, make purchases, and transfer money on behalf of users or companies. The product accepts funding through bank transfers, payment cards, or stablecoins, which can be held as fiat in bank accounts or as stablecoins in embedded wallets. Agents can pay with Visa or Mastercard cards, send funds to bank accounts, or transfer stablecoins directly. Users or platforms can set spending limits, specify merchants or recipients, and restrict payment times.
