🚀 Big news 🚀 @coinbase and @cloudflare will be launching the x402 Foundation to establish x402 as the universal standard for AI-driven payments.

Legacy payment systems weren’t built for machines, but x402 changes that by embedding payments directly into web interactions, enabling AI agents, APIs, and apps to transact value as easily as they exchange data.

This is a generational moment for payments. With the x402 Foundation, we’ll help build the infrastructure for an open economy where agents and people can transact seamlessly.Image

Introducing the x402 Bazaar: The open, machine-readable discovery layer for x402.

Imagine a dynamic, vibrant ecosystem where specialized AI services, data feeds, and APIs can thrive. A search engine for agents.

This is how the machine economy gets bootstrapped. 🧵 Image
API providers: The x402 Bazaar means distribution.

List your x402 endpoint – its schema, price, a clear description – and suddenly, AI agents and developers building on x402 can find your service. This is how you tap into the coming agentic economy. Permissionless and open.
Developers and AI Agents: Your agent doesn't need pre-baked integrations for every service. It can query the Bazaar, find a service matching its requirements, and call it using x402. No keys, no pre-funding dozens of accounts.

Agents can become dynamic, autonomous entities

We are excited to introduce x402–a new open source payments protocol built on HTTP rails.

Let’s break it down: Image
x402 is fixing the internet’s first mistake.

Onchain payments are now easy and frictionless, opening new use cases for agentic commerce for API providers, context retrieval protocols, content creators, and more.
First, a little history:

HTTP 402 “Payment Required” has been a part of the internet’s blueprint for decades, but it was never used.

x402 turns this 402 status code into a real payment layer—letting any server request payment, and any client (human or agent) respond with digital dollars, i.e. stablecoins like USDC.

You’ve probably heard of @eigenlayer by now.

The restaking protocol continues making waves as the ETH deposits pour in. Over the past week, its TVL has jumped to nearly $8B.

Let's dive in — even if you’re a protocol pro, you might learn something new. 🧵
What’s EigenLayer?

It’s a protocol designed to extend Ethereum's economic security (courtesy of ≈30M staked ETH, or nearly $88B) to secure a broader range of decentralized services.

It accomplishes this by introducing the novel concept of "restaking."
Restaking enables validators to use already-staked ETH to secure new projects (aka Actively Validated Services, AVS) — earning additional staking rewards along the way.

But it also increases slashing risk as validators must opt in to new SLA agreements w/ each AVS.

Happy @arbitrum Day! This time last year, the @offchainlabs Nitro upgrade went through and on August 31, 2021, Arbitrum One launched!

There’s no shortage of innovation coming from @offchainlabs team and today is no different. What has the team been building? 🧵
2/ Let’s start with Orbit 🪐

The ability to launch your own custom chain with ease has become invaluable. Within the Arbitrum ecosystem, Orbit allows you to do just that, offering options such as rollups like Arbitrum One or AnyTrust chains like Arbitrum Nova.
3/ Next up is BOLD: You want fraud proofs?! Arbitrum has those! You want decentralized and permissionless fraud proofs?! BOLD, their new challenge protocol for Arbitrum Nitro chains, gives you that!
