Mastercard Opens Card Rails to AI Agents With 30-Plus Crypto Partners

Mastercard extended its payments network to autonomous AI agents on Wednesday, unveiling Agent Pay for Machines (AP4M) with more than 30 launch partners spanning crypto infrastructure, stablecoin issuers, payment processors and DeFi protocols.

The company announced the launch Wednesday morning via its official X account, naming Coinbase, RippleX, Stripe, Solana Foundation, Polygon, Aave Labs, OKX, Stellar, MoonPay, Adyen, Alchemy, Anchorage Digital, Ant International, Checkout.com, Cloudflare, Crossmint, Getnet by Santander, Global Payments, Nevermined, Rain and Utila among its 31 initial participants.

"Launching with 30+ partners to bring this to life from day one. This isn't just more payments. It's a new operating model for commerce," Mastercard said.

The Product

Agent Pay for Machines (AP4M) positions Mastercard's network as the governance and trust layer for commerce conducted entirely between software agents, without human checkout flows. The system covers four functions: credentialing registered agents, permissioning what they can spend, transacting via card and account rails, and settling in either traditional currencies or stablecoins.

Mastercard described its ambition in scale terms.

"As AI agents begin to act, payments move into the background -- at machine speed and massive scale," the company said Wednesday. "Bringing structure, governance, and trust to this new class of payments" was its stated goal.

The platform attaches Verifiable Intent, spending limits and authorization rules to individual agents. The design distinguishes sanctioned machine-to-machine transactions from unauthorized activity. Mastercard cited a flower shop using an AI agent to purchase domains, hosting and checkout infrastructure as one use case, and a logistics agent paying freight, warehouse and cold-chain monitoring fees automatically as another.

The DeFi Layer

Aave Labs joined as a launch partner, and Aave founder Stani Kulechov positioned the protocol as the credit infrastructure for the new payment class, describing Aave as the "credit layer for agentic payments." The framing indicates DeFi lending protocols intend to extend on-chain credit lines to registered AI agents, not only to human borrowers.

The stablecoin settlement option connects AP4M to Mastercard's broader digital-asset build. Coinbase and RippleX on the partner list carry stablecoin connections: Coinbase operates USDC alongside Circle, and Ripple issues RLUSD. Anchorage Digital, the only federally chartered crypto bank, and MoonPay, which Mastercard partnered with in May 2025 to support stablecoin payments at checkout, also appear on the partner list.

Distinct From the April Stablecoin Product

AP4M is a separate product from Mastercard's 24/7 stablecoin-settlement rollout, announced in April 2025, which targeted human payment flows on existing card and wallet infrastructure. AP4M targets non-human principals: software agents acting on programmatic instructions with no human in the transaction loop.

The structural difference sits in the identity layer. AP4M requires each agent to be registered and verified before initiating a transaction. The April stablecoin product required only a wallet and a merchant terminal.

Program History

Mastercard first announced its Agentic Payments Program in an April 2025 press release that focused on consumer-facing delegation and named Microsoft as its first major collaborator. Chief Product Officer Jorn Lambert described the goal as "redefining commerce in the AI era, including new merchant interfaces to distinguish trusted agents from bad actors."

AP4M extends the program to fully autonomous machine-to-machine commerce, where no delegation from a human principal occurs at transaction time. Solana Foundation, Polygon and Stellar all confirmed launch-partner status on their own X channels Wednesday morning, indicating AP4M reaches multiple blockchain settlement networks from day one.
