The most exciting work happens when builders take the lead.

Fiber Link: From Prototype to Product-Ready

Fiber Link has published its latest product delivery report, marking its transition from an engineering prototype toward a product-ready, deployable release.

Built as an open-source tipping layer for online communities, Fiber Link lets users tip posts or replies directly from familiar forum interfaces (starting with Discourse), without requiring members to run their own Fiber nodes.

This milestone includes a video demo with comprehensive documentation for administrators and operators to deploy the service.

Fiber-Pay v0.2.5: Simplified Connect Flow & New Demos

Fiber Pay is a toolkit that allows AI agents to manage Fiber Network operations like opening channels and making payments. Its latest release introduces ConnectButton, a simplified way for frontend apps to connect to a Fiber browser node using passkey or password authentication with minimal setup.

This update also includes stability fixes for useFiberNode under React StrictMode, a refreshed browser-wallet demo with the new connect flow, and a quick-card demo showing payment integration and UI customization.

Decentralized AI Agent Calling Experiment via Fiber

Built on top of the latest Fiber-Pay release, this experiment explores a decentralized AI Agent calling platform. Users can invoke agents running on remote hardware from their browsers, with peer-to-peer payments, similar in experience to cloud-based agent services.

Key aspects include:

  • Instant Micropayments: L402-style payment flow currently with per-call pricing (currently 0.1 CKB on testnet) via Fiber.
  • Decentralized design: Agents are hosted by anonymous operators, reducing reliance on centralized APIs and allowing users to access the latest agent capabilities by updating their local clients.
  • Technical Implementation: Focuses on containerized agent runtime for isolation, the acpx library to support multiple agent types, and environment variable control to prevent sensitive API key leakage.

Spark Proposal: Dular—Mobile Money Stablecoin Wallet

Dular is a stablecoin wallet designed to bridge Fiber with the mobile money ecosystem. It replaces hex addresses with phone number identities and supports USSD access for feature phones. It leverages Fiber’s low-fee, native multi-asset channels to enable instant payments, with integrated M-Pesa on/off ramps.

  • Status: Additional evidence and documentation submitted; currently under committee review.

The Fiber Network AMA

https://preview.redd.it/0un30m6hw2zg1.png?width=1928&format=png&auto=webp&s=823eb98ceed3128a9fdb9a74769df2ae5b354b5c

12th May 11 GMT on Reddit

Hello, ladies and gentlemen of the CKB variety. Another Nervos community AMA is rolling out on May 12th, and this time it’s with one of CKB’s DevRel engineers Retric.

Retric is focused on documentation and developer tooling for the CKB ecosystem. Recently, he has been exploring community-driven experiments around the Fiber Network (CKB’s private, interoperable, multi-asset payment channel network), including projects such as Fiber Audio Player and Fiber L402 blog prototype. These demonstrate a paywalled publishing architecture powered by the Fiber Network.

The Fiber Audio Player is a lightweight demo app that puts the idea into practice, showing how content access can be gated behind a Fiber payment flow.

The Fiber L402 blog prototype explores a paywalled publishing model using L402-style authentication patterns, paired with Fiber as the payment rail, to unlock posts once payment conditions are met.

The Spark Program | Fiber-checkout has completed.

Built by community developer Salman, Fiber-Checkout is a Stripe-style React payment library for the Fiber Network.

Drop-in <FiberCheckout /> component plus useFiberInvoice / useFiberPayment hooks, dual RPC / WASM backends, multi-asset support out of the box (CKB, RUSD, SEAL, any RGB++ UDT).

The Committee's take:

Fiber has the technical potential to reshape crypto payments and is shifting CKB from a storage-oriented chain toward payment infrastructure, though whether that potential converts ultimately depends on ecosystem density, application adoption, and network effects.

Hence, we look for more attempts like Fiber-Checkout emerged within our community.

Forum thread: https://talk.nervos.org/t/10045/26

GitHub: https://github.com/salmansarwarr/Fiber-checkout

npm: https://www.npmjs.com/package/fiber-checkout

Live demo: https://fiber-checkout.vercel.app/

Demo video: https://www.youtube.com/watch?v=bWKslRFl-98

The full Nervos Talk link (and proposal) here on reddit: (10 minute technical read)

Fiber-checkout — A React component library and hooks package that lets any web developer add Fiber Network payments to their app in minutes. Drop in a component, and your site can instantly accept payments in CKB, RUSD, or SEAL via Fiber — no raw JSON-RPC, no manual hex encoding, no Rust knowledge required.

Team Salman — Blockchain developer specializing in developer tooling, security and payment integrations. GitHub: salmansarwarr Discord: salmansarwarr32

The Problem

Fiber Network is live on mainnet. It supports instant, near-zero-fee payments in CKB, RUSD (Stable++), and SEAL. The Nervos team just published u/nervosnetwork/fiber-js — a JavaScript wrapper over Fiber’s WASM — five days ago. The protocol works. The JavaScript bridge works.

But there is still no way for a web developer to add a “Pay with Fiber” button to their app.

To accept a Fiber payment today, a developer must:

  • Manually call the new_invoice JSON-RPC method with raw hex-encoded u128 amounts and Option UDT type scripts
  • Hand-render a payment request string into a QR code themselves
  • Poll get_payment on a timer, parse the response, and manage success/failure/expiry states manually
  • Do all of this with zero type safety, zero UI components, and zero examples

This is not a documentation problem. It is a missing tool. Fiber is fast, cheap, and live — but right now it is only accessible to developers who are already deep in the CKB stack.

The Solution

Fiber-Checkout — a React component library built on top of u/nervosnetwork/fiber-js (v0.7.x) that handles the entire payment flow in a single component.

Fiber supports CKB, RUSD, SEAL, and any RGB++ UDT token natively — a checkout component here is not a Lightning clone, it’s a payment tool that only exists because of CKB’s unique asset architecture.

import { FiberCheckout } from 'fiber-checkout';

&lt;FiberCheckout
  amount={5}
  asset="RUSD"
  nodeUrl="..."
  // onSuccess and onExpired accept any callback
  // e.g. fulfilling an order on payment or showing a retry button on expiry
  onSuccess={handleSuccess}
  onExpired={handleExpired}
/&gt;

Under the hood, Fiber-Checkout handles:

  • Calling new_invoice with correctly encoded amounts and UDT type scripts
  • Rendering the payment request as a scannable QR code
  • Polling get_payment every 2 seconds until settled, expired, or failed
  • Displaying real-time status: Waiting, Processing, Paid, or Expired
  • Surfacing human-readable errors when the node is unreachable

For developers who want lower-level control without the UI, the library also exports two standalone hooks:

const { invoice, paymentHash, expiresAt } = useFiberInvoice({
  amountCkb: 5,
  asset: 'RUSD',
  expirySeconds: 3600,
  nodeUrl: '...'
});

const { status, feePaid } = useFiberPayment({
  paymentHash,
  nodeUrl: '...'
});
// status: pending, processing, success, failed, or expired

Technical Approach

  • u/nervosnetwork/fiber-js v0.7.x — official Fiber JavaScript WASM wrapper (explicitly targeted; breaking change patches will be applied within the 4-week window if needed)
  • React 18+ with TypeScript strict mode
  • Zero styling dependencies — ships with minimal unstyled base components plus optional CSS classes, so it fits any design system
  • Deliberately narrow scope — we wrap only new_invoice and get_payment. Channel management and node administration are infrastructure concerns, not checkout concerns.

npm package structure:

fiber-checkout
  FiberCheckout     (React component, full UI flow)
  useFiberInvoice   (Hook, invoice generation only)
  useFiberPayment   (Hook, payment status polling only)
  FiberError        (Typed error class)

Ships as: CommonJS + ESM dual build, React 18+ peer dependency, MIT license, published to npm as Fiber-Checkout.

Deliverables

  • npm package — published, MIT licensed, works against Fiber testnet out of the box
  • GitHub repository — Full TypeScript source, JSDoc on every export, README with testnet quickstart (zero to first accepted payment in under 15 minutes)
  • Live testnet demo page — A hosted webpage accepting real Fiber testnet payments, with transactions visible on the Fiber testnet explorer
  • Companion guide — End-to-end walkthrough covering Fiber node setup through to first accepted payment in a Next.js app
  • Demo video — Screen recording: npm install, component rendered, real testnet payment received in under 10 minutes
  • Completion report — Public post on Nervos Talk with transparent fund usage breakdown and Fiber version compatibility notes

Funding Request — $1,200 USD equivalent in CKB

Week 1 — $250 | useFiberInvoice hook + testnet verification new_invoice with UDT type scripts requires careful handling — RUSD and SEAL have different script hashes that need testnet verification

Week 2 — $550 | useFiberPayment hook + FiberCheckout component Core of the project — all UI states, polling logic, error handling, and full TypeScript types

Week 3 — $250 | Cross-browser QA + mobile testing + live demo page Real testnet payments required for demo; mobile responsive layout; Safari WASM compatibility check

Week 4 — $150 | npm publish + companion guide + demo video + completion report Documentation is a first-class deliverable

Timeline

  • Week 1 — useFiberInvoice working on testnet with CKB + RUSD, repo public
  • Week 2 — FiberCheckout component + useFiberPayment hook complete
  • Week 3 — Cross-browser QA done, live testnet demo page deployed
  • Week 4 — npm published, guide posted on Nervos Talk, demo video live, completion report submitted

Estimated completion: 4 weeks from approval.

CKB Ecosystem Relevance

Nervos shut down Godwoken and Force Bridge to focus resources on Fiber Network.

That is not a roadmap promise — it is a demonstrated strategic commitment. But a payment network with no checkout tooling is a payment network that only protocol developers can use.

Fiber-Checkout is the missing link between Fiber’s technical capabilities and the moment a developer adds a “Pay with Fiber” button to a real product.

Every commerce app, tipping tool, subscription service, or peer-to-peer marketplace built on Fiber in the next 12 months will likely start with this component or the patterns it establishes.
