📣We're excited to share that Bitcoin Light is now live on Google Play and Apple Store!
You can now buy, send, and receive $BTC on the app while having full access to $CKB including staking on @NervosNetwork DAO⚡️
📲 This is just the beginning. Try https://t.co/Lz9fH7ZfOS now!
A wallet should never sign something it cannot read. 🔒
In the Fiber SDK we are building, the device rebuilds every message the node asks it to sign, checks it against its own policy, and refuses anything that does not match. Blind approval is the failure we designed out.
Lightning in BitcoinLight is powered by Breez, and Lightning is an open network. ⚡
You can pay or be paid by anyone on it, whatever wallet they use, with small fees and keys that never leave your device.

Fiber is a payment-channel network for Nervos, built on the same ideas as Lightning. ⚡
Two sides open a channel, pay each other off-chain as often as they like, and settle on-chain once. The speed comes from not asking the chain to witness every payment. @FiberDevs

When did you last check that your recovery phrase actually works? 🔑
A backup you have never restored from is a guess, not a plan. Write it down, keep it offline, and make sure you can read every word back.
Your keys only help you if you can reach them.
We're building an SDK for Fiber, the payment-channel network on Nervos. 🔑
A provider can run the node, but the keys stay on your phone. Every channel secret comes from your seed, and the device signs only what it approves.
In development, and built so any wallet could use it.
A screenshot of your seed phrase is a copy you no longer control. 📸
Photos sync to the cloud, get shared by accident, and end up in places you never meant. Write it on paper, store it offline, and keep it somewhere only you can reach. 🔑
Need a mobile wallet for Bitcoin and Nervos in the same place? 📱 BitcoinLight is built for self-custody, with BTC and native CKB support on iOS and Android.

Before you hit send, check the first and last few characters of the address. 🔍
Some malware quietly swaps a copied address for the attacker's own. A ten-second check is the cheapest protection you have, whether you're sending BTC or CKB.
A payment that starts on Fiber could land as Lightning BTC on the other side. ⚡
Both networks run on payment channels and multi-hop routing, so a hub can sit between them and pass value across.
Fiber is still in development on our side, and that reach is why. @ckba_build
Most payment networks are islands. Fiber is being built to reach the biggest one next door.
Fiber and Lightning share the same basic machinery, payment channels and multi-hop routing, so a Cross-Chain Hub can sit between them and link a payment on one network to a payment on the other.
Say Alice holds assets on Fiber and wants to pay Bob, who only takes BTC over Lightning.
The hub accepts her Fiber-side payment and makes the matching Lightning payment to Bob, and the two are tied together by the same cryptographic secret, so revealing it to settle one side is what settles the other.
The hub provides liquidity and connectivity, not custody.
It cannot claim the incoming payment without making the outgoing one, because if the condition is not met in time, both sides unwind.

Buying Bitcoin should not mean giving up custody afterward. 💳
BitcoinLight includes a fiat on-ramp through Meld, so you can buy BTC and manage it from the same non-custodial mobile wallet you control.

People ask why we'd build a Fiber SDK that helps projects beyond our own wallet. 🌱 Because we're not just building on Nervos, we're building for it. Bitcoin and Nervos are both first-class here, and shared tooling makes the whole ecosystem stronger. @NervosNetwork
Bitcoin uses UTXOs: coins are tracked as individual pieces of spendable value. 🧩
Nervos builds on a related idea with cells, giving CKB a flexible foundation for assets and apps.

Congrats to every team still building after the Fiber hackathon. 🚀
The prizes are the easy part. Projects that keep moving afterwards are what grow an ecosystem.
We're working on our own Fiber integration and an SDK, so it's great to build alongside you. @FiberDevs
Hackathon's over, building definitely not. Ideas are bouncing between projects and winners keep evolving! 👀
We're seeing @ebubedev delivering beyond scope on Fiber Studio, @Code3ks refining the Cashu + Fiber, plus updates from CLASP's scoped, permissioned payments by @enochidx, and early prototypes & RFCs from @ILE_Labs on channel rebalancing and @midnightexplr on routed machine payment sessions.

What could payment channels unlock on Nervos? ⚡ Payments so small and cheap they stop making sense on-chain: tipping, pay-per-use, machine-to-machine. That's the kind of thing Fiber is built for, and why we're still digging into it. @NervosNetwork
The Nervos DAO is built into BitcoinLight for CKB holders who use it. 🏛️
You can deposit, withdraw, and claim protocol compensation from your phone. It is a Nervos mechanism, not a BitcoinLight yield product or promise.
Work continues on the Fiber SDK we've talked about. 🛠️ The aim is simple: let any Nervos builder add Fiber payment channels without solving the same problem from scratch. Still in development, and still something we believe in. @FiberDevs @NervosNetwork
CKB is native in BitcoinLight. 🔑
You can send and receive CKB from the same mobile wallet you use for Bitcoin. Same self-custody principle: your keys stay with you.

A detail about Fiber worth knowing: it's designed to carry more than one asset. 🎯 Where Lightning moves BTC, Fiber can move CKB and other Nervos assets across the same channels. That flexibility is a big part of why we keep exploring it. @FiberDevs
Lightning is built for fast Bitcoin payments. ⚡
In BitcoinLight, Lightning is available through Breez integration, bringing quick BTC transfers into the same self-custody mobile experience you use for Bitcoin and Nervos.
BitcoinLight grew out of CKBull, and building on Nervos shaped how we think about self-custody.
Proud to still be here, alongside a builder community that kept growing through the hard years. 🚀 @NervosNetwork
One of the more encouraging things this year is that CKB’s builder ecosystem kept expanding while much of the industry was doing the opposite.
Teams were shrinking, budgets were being cut, and a lot of speculative activity disappeared.
Meanwhile, more developers kept showing up to experiment on CKB.
Today, over 100 are working on or exploring the network:
- 70 formal CKBuilders working through a structured program
- ~40 more coming in through Build on CKB, an open group for developers curious about the chain
- 45 projects now listed on the CKBuilder tracker, with 23 added in a single quarter and 15 submitted for technical review by core CKB developers
Claw & Order, a two-week AI Agent hackathon, closed with 22 open-source submissions; 16 came from CKBuilders, including the top two prize winners
- The work spans a surprisingly wide range: ZK key recovery for AI agents, a Groth16 zkSNARK verifier, a Fiber desktop client, an ML-DSA post-quantum implementation, a DID reference dashboard, lending primitives, prediction pools, and more
Some of these builders are now graduating from experimentation into independent projects.
But the more important signal is that all of this happened during one of the bleakest periods for the industry.
If this is what the builder pipeline looks like when capital and attention are scarce…what happens when they aren’t? 👀
