X402 ($X402)

With x402 handling autonomous payments, and CARV injecting identity, reputation, and consent, we’re laying the groundwork for trust-minimised agent economies.

CARV is where agents don’t just act, they understand why.

Let’s imagine what @CashieCARV and x402 will look like, feel free to share your comments below 🤔🤔

BCS的X402 @BongTokenX，亮点是打的钱全加池子已锁，格局不错，市值2m池子就有1m

@MemeRadar_sol 抓庄筹码也健康

BSC 的第一个 x402 昨天已经有了，用的我们给 x402 提的 PR 中的代码。捆绑比较多，我也没早期筹码，可惜了。
现在还打着 BSC 第一个 x402 的都是骗了。

great overview of why x402 makes sense and the role blockchain has in enabling agent payments over the web

If you're interested in the x402 narrative, it's worth noting that $EIGEN is one of the only (and first) large caps building infra. Good read below.

if you are impressed by x402, #ERC8004 will blow your mind

#ERC8004 = identity & reputation for AI agents 🤖
#x402 = payments between them

#x402 and #ERC8004 together might change the way autonomous agents communicate, authenticate, and exchange value across the internet

here's everything you need to know about ERC 8004 👇

#ERC8004 might be the most important upgrade for the AI on-chain era

It’s called the Trustless Agent Standard and it basically gives AI agents an identity, reputation, and trust layer on Ethereum

with ERC8004, agents can now register themselves, verify each other, build reputation, and transact. All without human approval

this means machines can finally hire, pay, and collaborate with other machines directly on-chain

No middlemen, no centralized AI networks no fake trust 👀

It’s not a new coin or foundation of the upcoming agent economy. projects like $VIRTUAL, $SERV, $TAO, $FET, $DIRA are already building around it

ERC8004 turns Ethereum into the trust layer for autonomous agents and that actually changes everything

be early lads...

为什么说x402与ERC-8004其实是非常互补的未来AI机器经济的协议？而且完美适配0G所建立的基础设施？

•x402 作为一个高效的支付执行协议，成功解决了原子性、一次性交易的“最后一公里”问题，是启动机器经济不可或缺的工具。它极大地提升了交易效率，但其价值仅限于支付执行的瞬间。

•ERC-8004 的定位则远高于此。它通过构建一个包含身份、声誉与可验证凭证的信任框架，为AI代理之间建立长期、复杂和高价值的协作关系提供了基础。它着眼于构建整个经济生态的稳健性和长期价值，而非单次交易的效率。

而通过在0G这一专为AI设计的高性能基座上运行ERC-8004的信任协议，我们最终能够构建一个自洽的经济闭环：AI代理在0G上诞生、通过ERC-8004建立身份与信誉、交易0G网络提供的核心资源（数据与算力）、并使用x402等工具进行结算。这是一个真正面向未来的、全面而深刻的AI代理经济解决方案。

Why are x402 and ERC-8004 actually highly complementary protocols for the future AI machine economy — and perfectly aligned with the infrastructure built by 0G?

•x402, as a highly efficient payment execution protocol, successfully solves the “last-mile” problem of atomic, one-time transactions. It is an indispensable tool for activating the machine economy, greatly improving transactional efficiency — but its value is confined to the moment of payment execution.
•ERC-8004, on the other hand, operates at a much higher level. By establishing a trust framework encompassing identity, reputation, and verifiable credentials, it enables AI agents to form long-term, complex, and high-value collaborative relationships. Its focus is on building the robustness and long-term value of the entire economic ecosystem, rather than on single-transaction efficiency.

When the ERC-8004 trust protocol runs on 0G, an infrastructure purpose-built for AI, we can finally construct a self-consistent economic closed loop: AI agents are born on 0G, establish their identity and reputation through ERC-8004, trade for 0G network’s core resources (data and compute), and settle using tools like x402.

This forms a truly future-oriented, comprehensive, and profound solution for the AI agent economy.

The internet already defined a payment layer decades ago. HTTP 402 reserved space for a payment layer, but the web never had a native way to fulfill it. x402 enables web requests to carry value natively, with onchain verification in the same flow.

The reason crypto is indispensable isn’t ideological. It’s architectural.

1. Machines can’t run on credit.
The fiat stack was built for humans: authentication, KYC, chargebacks, and manual dispute loops. It assumes the buyer has an email, an identity, and patience.

AI agents can sign, but not KYC. They speak in cryptographic proofs, not passports. Fiat rails still depend on human-centric checkpoints, all of which break at machine speed.

Crypto wallets fix this at the primitive layer. Signatures replace identity, tokens replace intermediaries. x402 lets agents just pay, triggered by an HTTP header, with ERC-20 transfers verified within the same flow. It’s not UX, it’s protocol design.

2. Micropayments collapse under fiat economics.
Card networks weren’t designed for micro-transactions. Their 2–3% fees and fixed settlement costs break down below a dollar. A $0.001 query would lose money before it even clears. That’s why the web ossified around ads and subscriptions: friction made precision pricing impossible.

x402 restores true atomic micropayments to the web. On L2s like Base, transfers typically cost under a cent, low enough to meter every API call or compute cycle. “Payment Required” finally means what it should: pay exactly for what you use, no more, no less.

3. Settlement becomes a feature, not a liability.
Traditional rails treat settlement as a batch process, reconciled by banks and acquirers. Crypto compresses that window from days to seconds, and more importantly, makes every outcome cryptographically verifiable.

No chargebacks, no reversals, just deterministic state updates. The trade-off is intentional: machine commerce favors finality over forgiveness. That’s what enables autonomous transactions. Agents can trust code, not counterparties.

4. Programmability changes the game.
Card networks can’t express conditional logic at the transaction layer. You can’t tell Visa to “pay only if the query succeeds” or “stream $0.01 every second.” Crypto can.

x402 turns payments into programmable primitives, composable, inspectable, and automatable. That’s the difference between digital payments and internet-native money.

5. Tokenized cards aren’t a bridge; they’re ballast.
Putting credit cards onchain doesn’t fix the architecture. It still relies on centralized issuers, fiat settlement, and identity-linked trust. That model is structurally incompatible with a world where APIs and agents transact peer-to-peer, without permission or intermediaries.

Tokenized cards extend fiat’s reach, but they don’t make it autonomous. They replicate the old logic of control inside a new wrapper.

Crypto isn’t an add-on for x402. It’s the substrate that makes it possible.

HTTP 402 finally has a foundation that matches its intent: an open, programmable economy where computation and value converge.

x402 doesn’t make payments cheaper. It makes them native, native to the web’s protocol layer, where value moves with the same atomicity as information.
