Gm frens. Happy Tuesday. Let’s dive into today’s news.

• Google Agent Payments Protocol (AP2).

• L2Beat introduces Ecosystem Pages.

• Mantle upgrades to OP Succinct.

• The Ether Machine plans to go public.

Google introduced the Agent Payments Protocol (AP2), an open-source payment-agnostic standard that enables AI agents to securely transact across platforms on behalf of users, merchants, and providers. Built as an extension of the Agent2Agent (A2A) and Model Context Protocol (MCP), AP2 creates a common framework for agent authorization, authenticity, and accountability.. AP2 establishes trust through cryptographically signed “Mandates” and verifiable credentials, providing an auditable trail from intent to payment. It will also support stablecoin payments, while also extending into crypto with A2A x402, developed in collaboration with Coinbase, MetaMask, and the Ethereum Foundation. Backed by 60+ global partners, including American Express, Mastercard, PayPal, Intuit, Salesforce, and EigenLayer, AP2 is designed to unlock new commerce models and coordinated agent-to-agent transactions.

L2BEAT launched Ecosystem Pages, a new dashboard that aggregates data on Ethereum scaling ecosystems by deployment stack, including the Superchain, Arbitrum Orbit, the ZK Stack, and the AggLayer. The pages bring together key metrics such as total value secured (TVS), transaction activity, DA layer, and chain stages. The pages also track RaaS providers, governance data, and milestones or incidents.

Mantle upgraded its proof system to OP Succinct on mainnet, transitioning from an Optimistic Rollup to a ZK Validity Rollup on the OP Stack. The upgrade brings faster settlement with 1-hour finality and 12-hour withdrawals, greatly reducing capital idle time for users. All new state roots are now submitted and verified using ZK proofs. The migration is being executed in three phases: during the transition window, the bridge will continue enforcing the 7-day challenge period for security finalization, and on September 23, 2025, the final contract upgrade will activate the new 12-hour withdrawal logic. Mantle secures more than $2.2 billion in TVL on its L2 network.
