Odaily: Base posted on X that Mastercard is adopting an agentic payment method based on x402 and USDC, with settlement conducted through the Base network.

Odaily reports that the latest Dune data from X-Agent shows that, as of October 20, platform-related on-chain activity has reached 1,268,897 transactions, the number of Agentic Wallets has reached 39,649, and a cumulative total of 680,285 x402 payments and 233,188 AI Activity Syncs have been generated.According to Dune trend data, X-Agent on-chain activity showed significant growth in October, with Transactions rapidly expanding within the month, and x402 Payments also seeing notable growth recently.Compared with traditional AI products, which mainly measure user numbers, conversation volume, and model invocation volume, what is more noteworthy about this set of data is that AI Agents in the X-Agent ecosystem are gradually generating real, verifiable on-chain economic activity.Through infrastructure such as Agentic Wallet, x402 payments, and AI Activity Sync, Agents are moving beyond being mere information interaction tools and further becoming economic participants capable of executing tasks, using wallets, initiating payments, and generating on-chain records.This further validates the Agent Economy path that X-Agent is advancing:Build → Act → Pay → VerifyFrom "creating AI Agents" to "enabling Agents to truly execute and transact," X-Agent is attempting to connect Agent capabilities, on-chain execution, and payment settlement into a complete closed loop.As the scale of x402 payments and Agentic Wallets continues to grow, the Agent Economy is gradually transforming from a concept into real network activity that can be directly observed and measured through on-chain data.

Odaily Report: Blockchain platform Solana has launched x402 batch payment functionality through PayAI Network and BlockRunAI, enabling AI agents to initiate multiple USDC payments and settle them all through a single on-chain transaction.BlockRunAI has already applied this technology to its AI model routing service. The company states that by consolidating multiple model calls into a single USDC settlement, it can save over $20,000 per month in network fees and reduce latency by approximately 10x; its service provides access to over 113 AI models through a single endpoint.Solana development organization Anza stated that the upgrade to ultimately reduce Solana's block time to 200 milliseconds is expected to go live around 15:00 UTC on October 9, having previously been gradually reduced from 400 milliseconds to 350, 300, and 250 milliseconds.

Odaily News: Payment company Block announced on September 24 that it has integrated the Bitcoin Lightning Network into the x402 payment standard. The x402 protocol can complete verification and unlock data through Lightning Network invoices and payment preimages after a server returns an HTTP 402 payment request.Steve Lee, head of Spiral, Block's open-source Bitcoin research and development division, stated that the integration targets instant, low-cost micropayment use cases. Block has not yet disclosed a timeline for bringing the standard to Cash App, Square, or Bitkey, and the related Python implementation still needs to be tested on real nodes. (Bitcoin.com News)

Odaily reports that Bitcoin News posted on X that Block has joined the x402 Foundation and is providing Bitcoin Lightning Network support for x402, an open payment standard for AI agents. x402 embeds payments directly into HTTP, enabling AI agents to autonomously pay for goods, services, and other agent tools. Block stated that the Lightning Network is well-suited for the billions of instant, low-cost micropayments expected to be generated by the agent economy.

Odaily reports that Bitcoin News posted on X platform that the x402 Foundation has incorporated the Lightning Network payment specification into its open internet payment standards. x402 was initially developed by Coinbase, aiming to enable AI agents and applications to automatically complete payments and continue executing tasks upon receiving a "402 Payment Required" response, without needing to create accounts, enter credit card information, or manage API subscriptions.The protocol is now governed by the Linux Foundation, with participation from companies such as Cloudflare, Google, AWS, Visa, Mastercard, Stripe, and American Express. With the integration of the Lightning Network, AI agents can use satoshis to pay for API calls, data, computing power, MCP tools, and other digital resources, and cryptographically prove payment through Lightning Network preimages.

Odaily News: Cardano developers can build applications and AI agents that support payments in ADA and Cardano network tokens based on this suite, enabling AI agents to complete on-chain payments for services such as online data and computing resources. Cardano Foundation engineers have completed the relevant specifications and developed the client, server, and Facilitator responsible for verifying and submitting transactions; the first version supports TypeScript, with a Python version planned for release later.Currently, the Facilitator has only completed actual transaction testing on the Cardano pre-production network and is not yet running on the mainnet.

According to an official announcement from Arc, Circle's public chain, agentic payments are now live. Its Facilitator Service provides a managed integration path for x402 developers, accepts USDC, and supports on-chain settlement on Arc, Base, and Polygon; this path requires no Relayer keys or separate Gas fee wallets.

Odaily reports that Circle co-founder and CEO Jeremy Allaire posted on X that the Circle x402 Facilitator service is now live on Arc. The service supports USDC settlement on Arc, Base, and Polygon PoS through EIP-3009. In addition, with the launch of Arc, market demand for cirBTC is growing. Currently, Circle Mint customers can directly mint and redeem cirBTC natively within the app. Each cirBTC is backed 1:1 by native BTC and can be redeemed for native BTC at a 1:1 ratio.

Odaily News: Among these, Payai handled 1.3 million transactions, while Figment processed 687,000; the total transfer volume for x402 transactions that day was approximately $28,900, with an average fee of just $0.0138 per transaction.
