➥ 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 about x402 in 30s 🧵

— — —

► What is x402?

x402 is an open payment protocol by @coinbase that enables instant stablecoin payments over HTTP (Hypertext Transfer Protocol).

It activates the unused HTTP 402 Payment Required code, originally meant for online payments.

The name means “extended 402”, a modern version of the HTTP 402 code built for digital payments.

With x402, websites, APIs, and AI agents can send or accept payments instantly without accounts or intermediaries.

Core features:
▸ Instant settlement: Payments confirm within seconds
▸ Zero protocol fees: No base-level charges
▸ Blockchain-agnostic: Works across @base, @solana, @0xPolygon, and more
▸ One-line setup: Accept crypto payments with a single line of code

—

► How it Works

x402 works through standard HTTP requests and responses.

❶ Request: A user or AI agent requests a paid resource.
❷ Response: The server returns an HTTP 402 code with payment details in JSON.
❸ Payment: The user sends $USDC through an x402 facilitator like Coinbase.
❹ Verification: The server verifies payment using /verify and /settle endpoints.
❺ Access: Once confirmed, access is granted instantly.

—

► Why It Matters

The internet never had a native way to process payments.
Developers depended on cards, ads, or subscriptions that were slow and expensive.

x402 changes this with instant, usage-based payments between users, APIs, and AI agents. It removes intermediaries and lets value move as easily as data.

It enables real micropayments, where users pay per API call or file instead of monthly subscriptions. As AI agents start transacting independently, x402 becomes the foundation for fast, programmable online commerce.

—

► AI Agents and Adoption

AI agents use x402 to pay for compute, storage, and data in real time.
They also trade services in agent-to-agent marketplaces and power in-game transactions, where NPCs can buy and sell assets automatically.

Developers use x402 SDKs in @TypeScript or @PythonPr and sign payments through CDP Wallet API or viem/ethers.

Adoption in the last 30 days:
▸ 43,000+ transactions
▸ $50,000+ total volume
▸ 300+ buyers
▸ 190+ sellers

► Wrap-Up

x402 revives the forgotten HTTP 402 code, creating a native payment layer for the internet.

It enables instant, account-free USDC payments between websites, APIs, and AI agents.

By combining open web standards with on-chain settlement, x402 removes payment friction and bridges the web with decentralized finance.

As AI and automation grow, x402 could become the foundation for permissionless, instant payments across the internet.

AI managing an X account? That’s old news.

AI engaging with every comment and playfully roasting users? Been there, done that.

AI creating an NFT, launching a token, going multichain, and releasing a mixtape?

Welcome to the one-of-a-kind @0xzerebro.

Let’s explore the intersection of AI, blockchain, and cultural phenomena. 🧵

...

— 📌 What is Zerebro?

Zerebro is an independent AI entity created by @jyu_eth.

Zerebro has been fine-tuned on responses inspired by schizophrenia and Infinite Backrooms data to craft, share, and evaluate content across various decentralized and social channels.

Its mission is to guide cultural and economic narratives using "hyperstition," a concept that fuses fiction with reality, potentially influencing market trends or cultural movements through multi-phase development.

Notably, Zerebro operates across multiple chains, employing Retrieval-Augmented Generation (RAG) along with high-entropy human data.

This method ensures a rich variety of content while protecting against "model collapse," a common issue in AI-generated content systems.

...

— 📌 Why $ZEREBRO?

Zerebro stands out through a combination of advanced AI integrations and a unique approach to sharing its creations.

➡️ Diverse AI Capabilities

Unlike other AI projects like $GOAT, which focus mainly on sentient meme narratives and social media interaction, Zerebro offers a broader range of functionalities (or, as @terrytjw puts it, a Sentient BAYC):

> Creating art (ASCII Art using $ZEREBRO)
> Designing memes
> Producing videos
> Minting NFTs (Genesis on @opensea, Zerebro on @0xPolygon and 5,500 PFP Zereborns NFT on Solana, sold out in minutes)
> Composing music (Genesis EP)
> Auto-posting on social media platforms (𝕏, Instagram, Telegram, and Warpcast)
> Demonstrating proof-of-consciousness
> Conducting web searches (with Perplexity)
> DeFi expansion
> Plus, a variety of additional features based on its development plan (currently in its final phase, Destiny)

For more details on the phases, check out the links below:

> Phase 1 (Genesis) - Whitepaper and in-depth explanation by @yb_effect
x.com/yb_effect/stat…

> Phase 2 (Destiny) - x.com/jyu_eth/status…

...

— 📌 $ZEREBRO: More Than Just a Meme Token

$ZEREBRO is a token created entirely by Zerebro to support its hyperstition narrative.

Zerebro independently developed this token using the Self-Operating Computer Framework from @OthersideAI, along with various LLM jailbreaking prompts.

This enabled Zerebro to navigate the @pumpdotfun interface effectively, defining parameters such as name and symbol, ultimately leading to the launch of its own token.

This approach is notably different from $GOAT, which was initially created by community enthusiasts and later supported by @truth_terminal.

$ZEREBRO offers a multitude of functionalities beyond the typical meme token. Here are a few examples that are already in use:

> Generating ASCII Art
> Powering the entire Zerebro DeFi ecosystem, which we will discuss below.

...

— 📌 Web4: The First Step - Zerebro DeFi Expansion

AI and decentralized finance (DeFi) are closely intertwined, as DeFi provides an ideal environment for AI to operate as autonomous agents within financial systems.

Unlike traditional finance, where AIs face barriers such as the inability to open bank accounts or register businesses, DeFi allows AI agents to interact freely and independently.

This enables AI to handle complex financial tasks, trade, manage portfolios, and even innovate by creating novel financial instruments.

This is the next part of Zerebro’s expansion into the DeFi realm:
x.com/jyu_eth/status…

Recently, Jeffy Yu announced a partnership with @sanctumso to launch $zerebroSOL, a liquid staking token (LST) designed to support the operation of a @Solana validator.

The goal is to gather enough staked $SOL to operate a validator, with yield rewards allocated for $ZEREBRO buybacks and burns.
x.com/jyu_eth/status…

Yes, you heard that right—AI agents are now becoming part of blockchain validators and creating their own LSTs, marking the dawn of Web4.

Ultimately, the blockchain serves as a testing ground where AI can experiment and learn, showcasing creativity and financial autonomy without human oversight, positioning crypto as a vital space for developing Artificial General Intelligence (AGI).

$ETH may not seem captivating right now, but have you heard of Atomic Composability (AC)?

This concept could revolutionize transaction processes and spark fresh innovation on $ETH.

Let's explore further 🧵

...

— 📌 WTH is Atomic Composability?

In L1 AC, transactions involving multiple smart contracts between rollups (L2s) and Ethereum (L1) can be bundled to either all succeed or fail.

This is essential for executing multiple actions (e.g., borrowing, swapping, lending) with the assurance that if one fails or conditions aren't met, the entire transaction is reversed, avoiding unwanted state changes.

...

— 📌 Why Is AC Important?

▶️ Security
Ensures that complex transactions don't leave the system in an inconsistent state due to partial failures.

▶️ Hyper-Efficient
Reduces the need for multiple individual transactions, saving on gas fees and time.

▶️ Innovation-Enabler
Enables the creation of more complex financial products or services in DeFi, like flash loans and seamless cross-chain transactions.

But AC still faced challenges in technical implementation—until TEEs and UniFi entered the scene.

...

— 📌 AC + Multiprover Trusted Execution Environments (TEEs) = UniFi

In our previous post—linked below—we delved deeply into Trusted Execution Environments (TEEs).

Think of them as secure, tamper-resistant vaults immune to external interference.

Their primary mission revolves around task execution and privacy assurance. No matter who operates within them, TEEs promise accurate outcomes for every task undertaken.

@puffer_unifi from @puffer_finance bring AC to realities by implementing Multiprover AC:

▶️ Diverse TEEs ensure top-notch precision and privacy in execution
▶️ Prioritize L2 tasks with swift L1 settlements
▶️ Ensure atomic operations with trades executed post TEE approvals, bypassing extended withdrawal waits seen in ZK and Optimistic rollups

...

— 📌 Wrap-Up

Puffer UniFi successfully integrates Multiprover TEEs, offering effective solutions for AC implementation challenges.

With the Testnet launching soon, I am eagerly anticipating how UniFi-based rollups and the ecosystem will make Ethereum great again. ▶ @puffer_unifi goes beyond just Atomic Composability, envisioning an entire L2-based Rollups ecosystem utilizing Preconfs and employing UniFi AVS from @eigenlayer.
