Key Takeaways:
- Lobster.cash and Mastercard will let Openclaw’s 1 million-plus AI agents charge purchases to existing Mastercard cards.
- The Verifiable Intent framework, co-developed with Google, cryptographically ties each agent transaction to a user’s explicit April 2026 approval.
- Crossmint plans an early access rollout before expanding Mastercard Agent Pay to additional agentic platforms beyond Openclaw.
Lobster.cash Partners With Mastercard to Bring Card-Backed Payments to AI Agents
The integration targets the Openclaw ecosystem, which has deployed more than one million agents across 20-plus messaging platforms, making it one of the fastest-growing open-source projects on record. Through the partnership, Openclaw users can authorize AI agents to spend on their behalf without sharing card credentials directly with the agent.
Crossmint co-founder Alfonso Gomez-Jordana Manas said the goal is removing friction between cardholders and their agents. “They can put the card they already have to work for their agent, with the security and control they expect from Mastercard,” he remarked. “This is how agentic payments reach everyone.”
Each transaction will run through Mastercard’s network under issuer controls, meaning card issuers retain visibility into what agents are buying, for how much, and under what conditions. Lobster.cash also uses Basis Theory as the credential layer, keeping sensitive payment data off agent infrastructure entirely.
A key component of the deal is Mastercard’s Verifiable Intent framework, which produces cryptographic records confirming that a user authorized a specific transaction within defined limits. The framework was co-developed with Google and aligns with two emerging standards: the Agent Payments Protocol and the Universal Commerce Protocol.
Those records allow issuers, merchants, and platforms to independently verify agent activity after the fact. The system is designed to work across protocols, giving it flexibility as agentic platforms multiply.
Mastercard Chief Digital Officer Pablo Fourez said the integration extends the company’s payments network into developer-led environments. “By integrating with lobster.cash, we’re extending Mastercard’s trusted payments network and infrastructure to open agent platforms, enabling developers to innovate while ensuring consumers and issuers retain the same security and control they expect from Mastercard,” Fourez said.
Lobster.cash currently supports agents on platforms including Claude Code, Devin, Hermes, and Zo Computer in addition to Openclaw. Crossmint, the company behind it, is backed by Ribbit Capital and Franklin Templeton and serves more than 40,000 clients.
Mastercard Agent Pay is already deployed by major financial institutions including Santander, Commonwealth Bank of Australia, DBS, and UOB. Bringing it into lobster.cash extends that infrastructure to open platforms where developer-defined controls have historically governed agent spending.
Crossmint built lobster.cash on Solana and structured it around stablecoins, traditional card rails, and partners including Circle, Visa, Basis Theory, and Stytch. The platform gives users programmatic control over agent spending limits by merchant, amount, and payment method.
The companies plan to open an early access program before rolling out the integration to the full Openclaw ecosystem and additional agent platforms. A waitlist is available at lobster.cash.
As agentic commerce moves from experimentation into production, the question of who controls spending, and how that control is verified, is becoming more pressing. This integration puts that accountability on the card network rather than the agent developer.
