The most exciting work happens when builders take the lead.
Ahead of Bitcoin 2026, here’s a quick snapshot of what’s been happening across community projects building with Fiber.
Fiber-Checkout: Stripe-Style React Payment Library Now Completed
The fiber-checkout project has submitted its completion report, marking the delivery of a new payment tool for Fiber Network.
Built for React and Next.js, it wraps Fiber payment flows into a simple checkout component, replacing complex manual steps with a ready-to-use checkout component.
What shipped:
- npm package
- live demo
- documentation
- tested integrations
It was delivered within the planned 4-week timeline and is now ready for developers to plug into real apps.
- Support: Spark Program
Fiber Link: Testnet Keeps Running Smoothly
The Fiber Link team shared its latest Milestone 3 update. The long-running public Testnet demo remains stable and operational, with:
- 109 successful tips
- 32 successful withdrawals
- 1 channel rotation for replenishing liquidity.
Next up: improved operator-friendly deployment and plugin installation guides to support future handoff and independent operation.
- Support: CKB Community Fund
Dular: Mobile Money Stablecoin Wallet on Fiber
Dular is building a stablecoin wallet designed for users in Africa, Southeast Asia, and Latin America, where mobile money is already the default payment experience. With Dular, instead of complex crypto wallets, users can:
- Send funds via phone numbers
- Deposit and withdraw through services like M-Pesa
- Access wallets via USSD on feature phones, without internet
Dular uses Fiber’s payment channel network to enables near-instant transfers with extremely low fees, while supporting native stablecoins and future local currency assets.
- Status: The project is currently updating its application based on reviewer feedback in order to proceed to formal committee review.

Backr: Creator Memberships Powered by Fiber
Backr is a creator platform that enables paid posts, subscriptions, and community interaction through wallet-based identities instead of traditional accounts.
How payments work:
- Subscriptions and renewals are paid via Fiber Network
- Creators selling memberships run their Fiber Nodes and configure its JSON-RPC endpoint in the app
- Backr coordinates Fiber invoice creation and payment handling on the server side, keeping the browser out of the payment flow.
This keeps payments non-custodial while giving creators full control over their setup.

LUME: Explores a Programmable Yield Layer
A community proposal LUME proposes a programmable yield layer built on top of RGB++, aiming to connect Bitcoin and CKB through yield, liquidity, and network participation
The idea:
- Users lock assets like CKB into a reserve-backed system
- Earn yield based on network activity and fees
- Build liquidity between BTC and CKB
In this design, Fiber Network would serve as a bridge and liquidity layer, connecting flows across systems.

Idea Feasibility Check: AI Workflow Monetization
Creators of open-source AI image/video generation often face a recurring issue: they build high-quality workflows, where the key values lies in a few critical parameters (e.g. CFG, steps, shift). These are easy to copy and redistribute without permission.
This idea explores a way to monetize AI workflow (especially ComfyUI) by separating its key parameters:
Concept:
- Main workflow stays open-source and runs locally
- Key parameters (like CFG, steps, tuning values) are encrypted and stored cheaply on CKB
- Fiber handles parameter retrieval and delivery back to the users
This enables a pay-per-use or pay-per-generation monetization model for creators while preserving an open ecosystem.

The ecosystem is still early, and most of what matters is happening in public — in forum posts, prototypes, and half-finished ideas that slowly turn into real products.
If you’re building something, here’s how we can support you:
- Spark Program: up to $2,000 for early MVPs (1–2 months)
- CKB Community Fund: DAO grants for broader ecosystem work
Share your progress on Nervos Talk, even if it’s just a rough idea. That’s usually where the interesting things start. We’ll likely feature more of these in the next Fiber Pulse.
