Rain announces AI agent payment infrastructure… supports stablecoin settlement

Rain on Tuesday launched Agent Vaults, a payment infrastructure for AI agents that lets users and businesses fund balances via bank accounts, cards, or stablecoins and set spending rules the agent cannot exceed. Purchases are made through per-transaction virtual cards with amount limits, merchant restrictions, and expiry dates, and Rain checks conditions at the authorization stage, holding out-of-policy purchases until user approval. The move matters because it gives autonomous agents a bounded, auditable way to transact without exposing full account access, targeting the emerging agentic-commerce market. What to watch next is adoption among agent developers and merchants, and whether stablecoin settlement becomes a meaningful share of vault funding.
