➥ x402 Revival: The Internet’s Native Payment System The internet always had a payment code called HTTP 402, but it was never activated. x402 finally activates it, turning the web into a programmable payment layer for both humans and AI agents. Everything you need to know…

I lead hiring for Coinbase's Associate Product Manager (APM) program, on top of my PM work for @CoinbaseDev we published the job opening for Summer'26 PM Interns today - link in 🧵 if you're a college student hungry to bring the world onchain - I'm looking for you 🫵
If you are in NYC next week, come out to this x402 community event hosted by @solana via @_rishinsharma. I'll be there! Come through!! 🔌 luma.com/56498u94?tk=Aj…
Every day I search for a game that scratches the same itch as Slay The Spire
Here are the actual Top 16 roguelikes of all time

Agents are way more powerful if they have the right tools for the job. x402 gives agents ♾️tools
Gave an agent a hot wallet + our new x402 AI SDK and throwing it on a while loop. Letting it call anything it can find on @x402scan. Base case, will result in some clean abstractions for adding 402 tools to agents. Best case, world domination?

📉 Less ads 📈 More micro payments. An inescapable path in a growing Agentic-driven world. x402 is the new https for Agentic commerce and will drive crypto adoption like no other use cases before.
If x402 takes off it will completely change the business model of the internet. Attention was the currency of the social internet. Microtransactions will be the currency of the AI internet. AIs consuming AI services using internet native micro payments. On Ethereum.


x402 is a nascent protocol aiming to do something profound. It’s not a smart contract; it’s the payment rail for the agentic era of accelerated computing. At its core, x402 is a beautifully simple design: it extends the existing HTTP 402 standard, allowing any web service to be…

After 6 months of real world x402 adoption, we're starting to plan v2. We've learned a ton and received amazing feedback from builders across the community that inspired the proposed v2. For your review: github.com/coinbase/x402/…

Who's hungry? 🍕🍕🍕 Just hacked OpenAI’s Pizza demo, added support for x402, and ordered some pizza!

got on camera today to talk about the native x402 integration that's coming to scout v0.3 i'm very clear on my stance: x402 is going to be a non-negotiable for agents, so we're investing into it at @darkresearchai early:
Matt Ober, Co-Founder & CTO of Pinata, on how x402 serves as a bridge between Web3 and Web2. “It allows these Web2 companies to jump in in a way that’s been kind of friction filled. It doesn’t need them to maintain a lot of complex Web3 infrastructure, just accept this standard…
Erik Reppel of Coinbase Developer Platform on the pitch for why builders should integrate x402. “Would you like to have something where AI agents can pay you and be part of the next phase of the internet?…x402 is just an open standard for how to transmit value. It’s the same…
