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)
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.
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.
global asset management firm BlackRock has released a research report titled "The Machine-Native Economy," arguing that as AI agents autonomously complete multi-step tasks, demand for onchain programmable payment infrastructure may increase, with stablecoins potentially used for payments and settlement.The report notes that traditional bank accounts and card payment mechanisms are ill-suited for sub-1-cent, round-the-clock machine-to-machine payments. Stablecoins can achieve near-instant settlement without requiring manual account opening or confirmation.BlackRock suggests that computing power could be wrapped into standardized contracts for buying, selling, collateralizing, or automatic settlement on the blockchain. TRM Labs' analysis of $52.7 million in x402 settlements this year shows that AI agents accounted for approximately 0.6% to 7.5% of payment volume. (Decrypt)

Odaily News, Coinbase stated on the X platform that the financial layer emerging around AI agents is called agentic finance, namely AiFi, covering agent transactions and agent commerce. AI agents can research information, make decisions, and execute actions on behalf of individuals and businesses, while also needing to perform fundamental financial activities such as making payments, receiving funds, storing value, and transferring money. Coinbase stated that it is building tools for AI agents to enable them to continuously execute financial operations within preset goals, permissions, limits, and security boundaries.Coinbase stated that Coinbase Advisor, Coinbase for Agents, x402, and Coinbase Business have formed the AiFi infrastructure. Coinbase Advisor is an SEC-registered investment advisor integrated into the app for Coinbase One users, providing portfolio analysis and guidance through a chat interface. Coinbase for Agents connects tools such as Claude, ChatGPT, and Cursor to Coinbase accounts via MCP, allowing users to set operating conditions and security boundaries for agents, as well as create separate sandbox accounts for agent use.Coinbase stated that x402 is an open payment standard initiated by Coinbase and now managed by an independent foundation, supporting AI agents in paying fees to other agents, applications, and services. To date, x402 has processed over 205 million transactions with a volume of $53 million, covering 200,000 sellers, with Coinbase facilitating 67% of this activity. Individual payments can be used for API calls, datasets, research materials, or computing resources.Coinbase stated that Coinbase Business supports enterprises in natively receiving USDC payments from AI agents, while Coinbiz helps merchants sell services and content to software without relying on card credentials, manual invoicing, or payment processes designed around human customers. Eligible businesses can earn a floating 3.35% reward on idle USDC balances. USDC currently accounts for 99% of on-chain agent commerce transactions, x402 accounts for 97% of agent finance protocol usage, and the related activities run on Base.
Odaily News: Brian Armstrong posted on X platform, stating that his team, together with x402 and @CoinbaseDev, has built a feature in Slack: users can ask questions to agents in Slack; if a complete answer requires paid services, the agent will directly purchase the service.
