It’s been incredible to see x402 go viral this week! For anyone new, welcome to the movement. I designed x402 to be the HTTP of money: a universally accepted, neutral, core primitive to help make the internet ready for the AI era. I can’t wait to see what people build 🛠️

it’s one thing to use Claude to plan your trip it’s another thing to have it actually book the room Just add Base and Travala MCP then ask for what you need. It'll find a hotel, book it and pay with x402

Agents can handle your travel now too @travalacom’s x402 integration on Base lets AI autonomously book hotels Book across 2.2M hotels with Travala's MCP

Are you polyagentist or monoagentist? Polyagentist: believe people will interact with many agents Monoagentist: believe people will interact primarily with a single agent

"It's when you give your agent access to secrets, to proprietary data, to the things that are hidden because they're valuable. That's when your agent becomes as interesting as possible." @programmer of x402 with @yugacohler of @CoinbaseDev on the Main Stage at ETHConf.

When money is programmable you can do anything. Batch settlement on x402 allows streams, sessions, and effectively no cap on transactions per second.

Update: I’ve left Coinbase. I’m starting a company. I’ll continue to be involved with x402 as a member of the Technical Steering Committee with the foundation, and as an advisor to Coinbase on agentic commerce. I’m incredibly proud of the work we’ve done in @CoinbaseDev. It's truly an elite team executing at the highest of levels. Many exciting things coming soon 👀. @yugacohler will be taking the helm as Head of Engineering, he’s a rockstar, he’ll crush it. It's been an exceptional second tour of duty at Coinbase. It was a hard decision to leave, but there's an idea in my head I need to get into the world. Big thank you to @barmstrong, @emiliemc and @nemild for bringing me back, and to @alecglovett, @yuga @brian__foster and everyone else in CDP - it's been an honour.

In the new AI era, I keep telling software engineers the same thing: Become multi-threaded. Get comfortable with context switching. For years, engineers optimized for “deep focus,” while managers protected their time to keep them in the zone. AI changes that. The best engineers now orchestrate multiple streams of work simultaneously, delegating execution to LLMs while continuously reviewing, steering, and adapting. Context switching is mentally exhausting. But like any skill, it can be trained. Start building it now, and you’ll be unstoppable.

Singapore’s Foreign Minister, Dr Balakrishnan casually explaining how he built his own AI agent (a 2nd brain for diplomacy) using Claude & WhatsApp integration etc. on a Raspberry Pi “You cannot govern a technology you have only been briefed on.” 🇸🇬

Batch settlement is now available via x402. Real useful for latency sensitive applications, as well as nano payments. Learn more 👇 Credit to @DukeOphir @carsonroscoe7 @ilikesymmetry
🚀x402 now supports batch settlement: Transact at extremely low latency and fractions of a cent Agents can now escrow funds once, then pay with off-chain vouchers. x402 sellers can settle a batch of payments in a single transaction, instead of settling every request

we just shipped interactive onboarding on agentic(.)market simulated terminal walks you through what x402 actually feels like. wallet check, service discovery, payment, results. in this demo the agent finds an a16z article behind a paywall, pays dripstack $0.01 in USDC, and pulls back a summary. no subscription, no API key, no credit card. when you're ready to try for real, copy the SKILL.md and paste into codex, claude, hermes, whatever you're building with.

💳 @programmer: "AI is about to break the internet's economic model." The x402 founder talks why agents ignore ads, and the $3-5T agentic economy that needs micro-transactions. On the @Anchorage Digital Mainstage at @consensus2026.
