x402 is working. That's actually the problem
➢ Payments are live. In the last 24H, x402 processed $3M+ transactions onchain
➢ Every second protocol out there is trying to ride the x402 wave by mentioning it
ChatGPT's instant checkout went live in September. The technical problem is solved. That's why the real problems are now visible🧵
➠ Can agents actually shop?
No. An agent can send money but can't evaluate what to buy. API discovery tools exist for devs. OpenAPI standards document endpoints. But no system lets an agent:
‣ Scan available services autonomously
‣ Compare pricing and reliability data in realtime
‣ Make vendor selections without human configuration
➠ What happens when payments fail?
The system breaks down at intent, not execution. Over half of merchants use AI fraud detection. Smart contract dispute clauses exist. But none of this solves the core problem.
When an agent misinterprets what you wanted and buys the wrong thing, who pays is the concern. You authorized the agent, not necessarily the specific transaction it chose. It's not fraud. It's not merchant error. It's intent confusion.
Remember there are no rules that work for agentic transactions. No automated system can decide whether the agent correctly understand what the human wanted.
➠ Is fraud actually concerning?
Yes, measurably. Fraud detection doesn't work for agents. An agent making 1,000 transactions/hour isn't suspicious, it's normal. Geographic signals mean nothing when agents have no location. Consumers can say "I didn't authorize that, my agent did." Liability is unclear across the entire chain.
We also don't know who's liable when agents mess up. Frameworks are being written. None are law. Nobody wants to be the test case, which slows commercial adoption.
@eigenlayer will play a big role in the verification part here. But it will need some external help in tackling frauds.
‣ x402 → payments
‣ AP2 → agent protocol
‣ EigenCloud → verification
➠ Where does money actually get made?
Not on payment rails. Those will be free or close to it. The money is in solving problems the protocol creates. New protocols can target these sectors:
➢ Fraud prevention at agent scale
➢ Dispute resolution that works in seconds/minutes
➢ Treasury management for thousands of micropayments daily
We will need reputation scores + regular audits. No machine speed reputation system exists where agents evaluate vendor trustworthiness at transaction speed is there as of now.
The other revenue source is accumulated intelligence. An agent managing your finances for two years knows spending patterns competitors can't quickly replicate. This is where ZK, privacy projects will be crucial moving forward.
➠ Conclusion
Note that realtime failure detection is becoming a regulatory expectation. Agents without failure detection guardrails will likely face pushback.
Systems get built fast, fixed slowly. Payment infra has arrived. Fraud reasons are immense. Disputes are confusing. Legal frameworks are incomplete. And adoption continues anyway because economic incentives are too strong to wait.
So next time you see a protocol saying that they've integrated x402, these are the questions you'll have to ask them instead of blindly hyping th protocol. X402 proved agents can pay. Now we're finding out what happens when they do.

For those who doesn't know what x402 is. This will be helpful👇
x402 just became the talk of the town lately for a reason🔥
➠ But WTF is x402?
It makes payments work like web requests. Settlement happens in seconds. No accounts, no KYC, no complex wallets. Just instant micropayments built into how the internet already works. If an AI agent needs an API?
Sends HTTP request → Gets 402 "Payment Required" → Pays USDC → Access granted.
➠ Why does it matters now?
AI agents need to pay for things autonomously. Buy compute, query databases, access APIs without humans approving each transaction. Traditional payment systems can't handle this. Too slow, too expensive, too much friction.
x402 solves it at the protocol level. Coinbase + Cloudflare built it, launched May 2025. Google integrated via AP2 protocol in September.
➠ Now which are the projects to look out for in this meta?
All using similar model i.e mint for ~1 USDC, automated verification, instant access. I'm personally betting longterm on infra projects like @Infinit_Labs @eigenlayer @virtuals_io @GoKiteAI! Remember 80-90% of meme + agent tokens launching on x402 are rugs. But infra is production ready with real adoption.
➠ Built on Base primarily, expanding to Solana, Peaq.
Uses USDC for settlements. Integrates with existing HTTP infra as devs can add it with minimal code. This can lead to real use cases...
> Agent buys API access for $0.001 per call
> NFT-gated content with instant USDC payments
> M2M transactions between devices
> Pay-per-use for compute or data queries
➠ ERC-4337 VS x402
The comparison most people miss. x402 is like complementary. Use ERC-4337 for the wallet, x402 for the payments flowing through it.
ERC-4337
> Does account abstraction i.e smart wallets with gasless transactions + social recovery
> It's about "how YOU interact" with blockchain.
x402
> Does payment embedding like instant settlements at HTTP level
> It's about "how AGENTS transact" on the web.
Google's AP2 integration shows institutions are interested in this too. If AI agents become economic actors, they need payment rails that work at internet speed. x402 is building that infra.

What are your thoughts on problems ahead for x402 guys?
