Something significant has been quietly taking shape at Ecency and Hive, and today I want to share it with the community.
Over the past weeks We've been working on bringing Hive - and specifically HBD - into a new open payment standard that is gaining serious traction across the Web3 and AI ecosystem: x402.
What is x402?
x402 is an open protocol built on top of the standard HTTP stack. It revives the long-dormant HTTP 402 Payment Required status code and turns it into a fully functional machine-to-machine payment layer. When a client - whether a human app, an AI agent, or any automated service - requests a resource, the server responds with 402 and payment instructions. The client pays, retries, and gets access.
No accounts. No API keys. No credit card forms. Just HTTP and a signed payment payload.
Coinbase launched the protocol, Cloudflare joined as a foundation partner, and it's Apache-2.0 licensed and genuinely permissionless. Any network can implement it.
What We've Built
1. Hive Namespace in ChainAgnostic (merged)
The x402 protocol uses CAIP-2 chain identifiers to specify which network a payment settles on - for example, eip155:8453 for Base. For Hive to participate as a first-class network, it needed a proper namespace registration in the cross-chain standard.
PR #174 to the ChainAgnostic/namespaces repository has been merged. It adds:
A CAIP-2 profile for Hive chain identifiers (
hive:mainnet)A CAIP-10 profile for Hive account identifiers (human-readable names, not hex addresses)
This is foundational work. Any protocol, wallet, or tool using CAIPs can now reference Hive natively and unambiguously.
2. Hive Scheme Spec in x402 Core (under review)
PR #1330 to the main coinbase/x402 repository adds Hive as a supported network in the exact payment scheme specification. It introduces:
specs/schemes/exact/scheme_exact_hive.md- a full scheme spec covering payload structure, secp256k1 signature verification against on-chain active key authorities, and settlement via direct transaction broadcastUpdates to the core
scheme_exact.mdto include Hive in the network reference list and critical validation requirements
This is a specification-only PR - the reference implementation is already complete and published separately. If you have some github (hive) power, feel free to leave a comment and encourage faster review. 😀
3. hive-x402 - The Full Implementation
The complete package lives at ecency/hive-x402, is published on npm as @hiveio/x402, and has a public facilitator running live at x402.ecency.com.
It includes everything needed to participate in the x402 ecosystem from the Hive side:
Facilitator server - verifies secp256k1 signatures against a Hive account's on-chain active keys, broadcasts HBD transfers, and tracks nonces to prevent replay attacks. Ships with SQLite out of the box and Redis for production. The public instance at x402.ecency.com is free to use.
Express, Next.js, and Hono middleware - gate any API endpoint behind an HBD micropayment with a single function call:
app.get("/api/premium", paywall({
amount: "0.050 HBD",
receivingAccount: "your-hive-account",
facilitatorUrl: "https://x402.ecency.com",
}), handler);
Client library - transparently handles the full 402 → sign → retry flow for AI agents and apps. Also ships browser-compatible building blocks for signing via Hive Keychain or HiveAuth without any Node.js dependencies.
const client = new HiveX402Client({
account: "alice",
activeKey: "5K...",
maxPayment: 0.1,
});
const res = await client.fetch("https://api.example.com/premium");
The implementation has 59 passing tests covering end-to-end payment flows, signature verification edge cases, nonce stores, rate limiting, malformed headers, and Express/Next.js middleware.
Why Hive + HBD is a Natural Fit
Hive has always had the technical properties that x402 needs but that most networks struggle to offer:
$0 transaction fees - every micropayment arrives in full. No gas eating into small amounts, which is the core problem that made earlier crypto micropayment ideas impractical.
3-second finality - settlement is near-instant. No waiting for confirmations.
HBD - an algorithmic stablecoin pegged to $1 USD. No volatility risk for service providers, no token approval steps needed.
Human-readable accounts -
alicepaysyour-service, not0x742d35Cc.... This matters for readability in logs, agents, and tooling.Battle-tested - Hive has processed billions of transactions since 2016.
As AI agents increasingly need to transact autonomously - paying for APIs, data, compute, and content - they will reach for payment rails that work programmatically over HTTP. With these contributions, Hive and HBD are now a legitimate option in that ecosystem alongside Base and Solana, with a proper namespace, protocol-level specification, a working facilitator, and a complete npm package.
For Ecency specifically, this opens a path where AI Credits/Points, Custom API access, and other services can be monetized using standard x402 middleware - the same pattern any Express or Next.js developer already knows, just settling in HBD.
Get Started
npm install @hiveio/x402
Live facilitator: https://x402.ecency.com
npm:
ChainAgnostic PR (merged): https://github.com/ChainAgnostic/namespaces/pull/174
x402 Core PR: https://github.com/coinbase/x402/pull/1330
The facilitator is free to use. If you're building APIs, AI tools, or any service that could benefit from zero-fee HBD micropayments, everything is ready to experiment with today. Feedback and contributions welcome.
Can you describe how to use it? Not how to build it? How does it work in practice and in what use cases?
I apologize for my stupidity - but I didn’t understand anything! 😊
Think of it like this:
No login.
No API keys.
No subscriptions.
Just:
request -> pay -> access
Right now, there are a lot of middle man on internet payments/shops
Now it's clear - thanks for the clarification!
How does it work without a hive account? How does the "website" get the money for the call?
same here
😂🤣
Us moment 🥲.
🤣 There are probably three of us now
Your comment resulted in some ease for me😂💃🏻
The news is interesting, so I decided to share it in a couple of threads:
In Spanish:
~~~ embed:2034778899008352482 twitter metadata:bWV0b2RvbG9naWFlY3N8fGh0dHBzOi8vdHdpdHRlci5jb20vbWV0b2RvbG9naWFlY3Mvc3RhdHVzLzIwMzQ3Nzg4OTkwMDgzNTI0ODJ8 ~~~
I hope this news gets out so we can have discussions and learn more about the topic, as it's something I haven't actually studied before.
So, it's basically an MCP payment gateway, right? Cool! :))
More like Stripe for APIs… but without accounts 😄 MCP is about how AI talks to tools, x402 is about how AI pays for those tools
I see :)
This is really great news. I already use BASE … earning $100 a day
BASE : https://base.app/profile/offgridlife
Nice 🔥
Similar to Base, Hive/HBD with zero fees - makes tiny payments way more practical.
Fantastic. BASE is a great place to buy/sell/trade Art NFTs
Will I be able to Swap my BASE USDC for HBD ?
With things like x402 growing, cross-chain swaps like this will likely get much smoother over time.
That’s great news…. There are millions of Artists with millions of USDC on BASE who will be very interested to earn 15% APR with HBD savings
with 15% on millions hive will go to 1 cent sooner or later.
Who knows.
Can you break this down to the understanding of a common man?
How does a regular Hive user or non-Hive user use this development?
I don't understand much, but I'll pay attention and investigate; I've already started reading the comments.
This is a game changer for Hive. Zero-fee HBD micropayments over standard HTTP is exactly the kind of tool the ecosystem needed. The x402 middleware pattern is very clean. I am excited to see how developers start building on this. Big respect to the Ecency team for getting Hive into the ChainAgnostic namespace and moving this forward. HBD as a payment method for AI agents is a genuinely exciting use case.
Good morning. This is great. Thank you for sharing all this information.
👍👏🍾🥂🕺💃!!!
Looks like a wonderful addition.
Great work, guys.
Ay, ay, ay! I wish I understood 1/2 of this. 😩 It sounds facinating!
@ecency @good-karma Could someone create a tutorial for the everyday-non-tech HIVER on how to use? Maybe we can do a live demo in Charla de Vida (my Podcast).
!LUV
!DIY
!BEER
This is mostly for developers and ai agents indeed, underlying technology basically allows simplest payment channels/integration for services and apps
But could or would the regular "Joe" like me benefit from that?
Yes via services you use. Imagine being able to pay on any service/thing on internet with HBD in future. x402 is that layer and this work adding Hive into that protocol, x402 will take time/adoption but we are ready
That’s very interesting. We could set up a standard paywall for external/internal/whatever. Is there probably something else?
Can we afford that?
I'm just a user here; I don't really understand the technology behind it.
Incrediboy 🤑
Sincerely speaking, i am lost. I don't even understand the whole thing.
Great work!
I was shocked that you actually mentioned the mirrornet in the specification 😯. That's great, more developers are using it!
Also, consider using
@hiveio/waxlibrary, as a replacement for@hiveio/dhive.Thanks, yes naturally I think, we will be migrating to
@hiveio/waxeverywhere...Btw, is there plans on optimizing bundle size?
Funny you should ask! 😅 We've actually been making great progress on optimizing our WASM packages and will be dropping an article as @thebeedevs about it soon. Naturally, WAX is next on our radar 😎
We've actually published some articles on this recently. When we measured the actual download size after installing all dependencies required by a given library, Wax proved to be a competitive tool — if not better optimized. Take a look:
As described there, this isn't our last word…
Great work 🔥
