## **Lightning Goes Mainstream 🚀**

![](https://substackcdn.com/image/fetch/$s_!59n2!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fac4b0bca-9d8e-481b-8bc0-3c25294d32ea_796x648.png)

It’s official folks: **Lightning is now mainstream.**

[Square just enabled bitcoin for *FOUR MILLION* merchants across the US](https://x.com/Breez_Tech/status/1988313617205166250). Four million more reasons for developers to pay more attention.

For developers everywhere the message really couldn’t be clearer: if your app doesn’t have Lightning yet, you’re going to be left behind. And if history is anything to go by, **the clip below** is a perfect preview of what happens when you ignore a seismic shift like this.

The *good news* is that it’s easy to catch up. The [Breez SDK](https://breez.technology/sdk) gives you everything a developer needs to add Lightning to any app. Minimal effort. Maximum flexibility. Start building today and join the future of bitcoin-powered apps.

## **Spark or Liquid? 👀**

![](https://substackcdn.com/image/fetch/$s_!HRP3!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fa58f29bf-d1b0-44bb-8b4a-b96f569a6294_722x722.png)

We get this question a lot: *What’s the best Breez SDK implementation? Spark or Liquid?*

**Our answer: You can’t go wrong with the Breez SDK.**

Choosing between our Spark and Liquid implementations is a developer’s dream dilemma. That’s why [Roy has broken things down in his latest post](https://blog.breez.technology/spark-or-liquid-you-cant-go-wrong-with-the-breez-sdk-c553e035fc4d), walking through the differences between the [two Nodeless implementations](https://breez.technology/sdk), and how each one unlocks different superpowers for your app.

Bitcoiners know the value of being early. Bitcoin is still young and reshaping global finance. Lightning is younger and reshaping Bitcoin. Spark and Liquid are *even* younger, and they’re finally turning bitcoin into the peer-to-peer electronic cash the world has been waiting for.

Choose Spark if you want instant settlement and offline support. Choose Liquid if privacy is your priority. Either way, the best move is to start building now because the future belongs to the developers who don’t wait for tomorrow.

## **It’s (Still) Time to Build ⚒️**

https://x.com/Breez_Tech/status/1995870823371210776

Builders around the world continued to answer the call for `</time2build>`.

As the challenge progresses, [submissions are starting to roll in](https://geyser.fund/grants/time2build). We’ve already seen integrations across events, gaming, Nostr, and more.

The global meetups haven’t slowed down either. Developers are still gathering across Europe, the Americas, Africa, and Asia as they look for inventive ways to bring bitcoin to existing open-source apps. And just in case you thought you’d missed the boat, there are still two weeks left, with submissions closing on **December 16**.

You know the drill by now. [It’s time to build](https://www.time2build.dev/).

## **Bringin(g) Bitcoin to Everyday Life 🥗**

![](https://substackcdn.com/image/fetch/$s_!9fOs!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F6323e98f-0703-468d-b778-75ccea1a6f24_480x270.gif)

For this month’s Lightning in the wild, we’re heading over to Europe.

[Bringin](https://t.co/fB1catWPEi) is freshly out of beta and ready to make bitcoin part of everyday life for Europeans. Since their release in October, we’ve seen a wave of videos showing the app in action.

Bitcoin in every app, used every day. *Let’s go.*

## **Amsterdam & Why Lightning? ⚡️**

![](https://substackcdn.com/image/fetch/$s_!4Hpp!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F04042a3d-4fff-489f-aa1e-9027cc1a235a_640x426.gif)

November saw Roy head over to Europe for the Bitcoin Conference in Amsterdam. He kicked things off with a [Q&A hosted by Shinobi on unlocking Bitcoin’s utility to make value move like information](https://x.com/Breez_Tech/status/1988979722014077397/).

![Image](https://substackcdn.com/image/fetch/$s_!1Oy0!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F95dc1ac8-4f69-4ab1-8fce-b1d469399825_1200x900.jpeg)

Later, on the Oranje stage, [he joined Jesse Shrader (Amboss) and Veronika Kütt (Arkade) for a panel on the user experience of bitcoin payments](https://x.com/Breez_Tech/status/1994425298805240295), where he reinforced what is fast becoming the mainstream view: [**Lightning is the common language of bitcoin**](https://blog.breez.technology/lightning-is-the-common-language-of-the-bitcoin-economy-eb8515341c11) as the technology moves into the spotlight.

With Lightning front and center, the online conversation followed the same energy as our partners took to social media to answer a simple question: “*Why Lightning?*”.

Have a read of what they had to say 👀

# Spark or Liquid? You Can’t Go Wrong with the Breez SDK

Fettucini or udon? Ramen or vermicelli? Many choices in life are between two things that are both great but just different enough to present a dilemma.

The [Breez SDK — Nodeless](https://breez.technology/sdk/) also has two flavors, and they’re both delicious. Choosing between the Spark and Liquid implementations of the Breez SDK is a developer’s dream dilemma. We released [the Liquid implementation](https://blog.breez.technology/to-help-bitcoin-flow-were-adding-some-liquid-to-the-breez-sdk-b56c14b0c9b0) of the Breez SDK last year. [The Spark implementation](https://blog.breez.technology/breez-spark-a-new-way-to-build-on-bitcoin-5abc3fb515cb) went into public beta a few weeks ago. Both are attracting attention and adoption, as the [most recent cohort](https://blog.breez.technology/the-breez-sdk-class-of-q3-2025-565356ef4335) of SDK partners shows, so both have proven themselves in solving real-world problems.

# **Many Implementations; Lightning is the Goal**

Thanks to new last-mile technologies, like Ark, Fedimint, Cashu, Liquid, and Spark, bitcoin is finally coming into its own as a medium of exchange. And Lightning is what’s making this evolution possible. As [the common language of Bitcoin](https://blog.breez.technology/lightning-is-the-common-language-of-the-bitcoin-economy-eb8515341c11), Lightning is what lets all these new technologies talk to each other and to the Bitcoin mainnet.

![](https://miro.medium.com/v2/resize:fit:1400/1*7RKDKyg4eJmcFW0hyQCuZw.png)

New last mile technologies are helping bitcoin thrive as a MoE.

This growth is entirely positive, and we support it. Breez has been in the Lightning business since the beginning, and fostering its utility and spread as the common language of Bitcoin is the purpose of all our SDK implementations. We [once dreamt of UX improvements](https://blog.breez.technology/lightning-at-the-end-of-the-tunnel-overcoming-bitcoins-ux-challenges-5738171c759e) like Lightning addresses and LNURL protocol support on top of basic functions like sending and receiving payments and on-chain interoperability. Our SDK implementations r̵e̵a̵l̵i̵z̵e̵ exceed these dreams and bring them within the grasp of all developers. They turn yesterday’s fantasy into today’s reality.

Breez has already released three SDK implementations: two Nodeless implementations based on [Liquid](https://sdk-doc-liquid.breez.technology/) and [Spark](https://sdk-doc-spark.breez.technology/) as well as a Native implementation based on Greenlight. But our laboratory never closes, and our roadmap includes further implementations to leverage other subnetworks and their specific utility profiles. And though we have since deprecated our Native Greenlight implementation, we’re actively working on a replacement based on [LDK](https://lightningdevkit.org/). If there’s a way to improve the Bitcoin UX with Lightning, we’re probably working on it or we’ve already built it.

Still, as the field of subnetworks and SDK implementations expands, developers are faced with the dilemma of what to choose. We added a Spark implementation because it offers different advantages and tradeoffs than our Liquid implementation. But our Liquid implementation is live and beloved because it remains the right fit for many use cases.

So our goal here is to give developers a sense of each implementation’s strengths and help them answer the question they’re asking themselves (and frequently ask us): *which Breez SDK implementation should I choose — Spark or Liquid?*

![](https://miro.medium.com/v2/resize:fit:1400/1*AbAtU-OG-2BPxtkwRdTg-w.png)

# **Spark: State(chain)-of-the-Art**

Spark, a new Bitcoin L2 introduced by [Lightspark](https://www.lightspark.com/), lets developers move bitcoin and stablecoins instantly and at low cost. Spark lets multiple users share a common UTXO managed by a group of operators called a Spark Entity. When you join a Spark, you deposit funds into a jointly controlled address and pre-sign a withdrawal so you can always unilaterally exit. Each payment updates the shared state with a new pre-signed transaction, creating a branching history of ownership where each finalized state is a “leaf.” Old keys are deleted after every update, ensuring only the latest state is valid. This setup enables trust-minimized, off-chain payments without changing the base UTXO. However, the [trust assumptions](https://docs.spark.money/learn/trust-model) it introduces are different from the Lightning Network.

### **Native L2**

Spark keeps bitcoin as bitcoin. Unlike Liquid, which converts BTC into a wrapped form known as L-BTC, Spark transfers the native asset directly within its statechain, preserving bitcoin’s on-chain integrity while enabling off-chain scalability.

### **No Minimum Amount**

Spark has no minimum transaction amount, making it ideal for low-value, high-volume activity such as nostr zaps. This distinguishes Spark from networks like Liquid, which impose a minimum transaction fee (currently 0.1 sats/vByte) to mitigate DoS attacks, which is a design choice that limits support for the smallest micropayments.

### **Unilateral Exits**

When joining a Spark Entity, users pre-sign an exit transaction that lets them unilaterally withdraw their funds on-chain at any time without requiring permission from the Spark Entity. While the cost to exit depends on factors like the transaction history and current on-chain fees, this capability is crucial for ensuring users can always reclaim their bitcoin independently.

### **Instant Settlement**

Spark’s statechain design doesn’t rely on block confirmations, so transfers settle as soon as they’re executed. By contrast, networks like Liquid require transactions to be included in a block, which typically occurs every minute under normal conditions.

### **Offline Receive**

One longstanding UX obstacle in Lightning is that the recipient needs to be online to claim their funds. There are workarounds using mobile notifications (which we’ve introduced as part of our Liquid implementation) to wake apps, but a workaround is always just a workaround.

[Become a member](https://miro.medium.com/v2/da:true/39309aa989a0b10efa2291d777f51465d571981b6b92231e51a0846a592cb403)

Spark shines with a means for recipients to [receive funds when they’re offline](https://docs.spark.money/learn/lightning), and it does so without jury-rigging notifications or gumming up the network’s liquidity with payments frozen in transit. It’s a UX improvement for users and operators alike.

### **Stablecoins & Tokens via BTKN**

Spark supports [BTKN](https://docs.spark.money/learn/tokens/hello-btkn), a token protocol based on [LRC-20](https://github.com/akitamiabtc/lrc-20), enabling users to issue, trade, and transfer stablecoins and other digital assets directly on the Spark network. This integration extends Spark’s utility beyond bitcoin payments, allowing seamless movement of different asset types while maintaining the same trust-minimized and self-custodial design.

Although the Breez Spark SDK is still in public beta, several apps have already adopted it for a diverse spectrum of use cases. It’s new, but it’s not untested, and we’re excited to see what new applications devs might come up with. If you have any questions, we have [more documentation available](https://sdk-doc-spark.breez.technology/), and we’re always ready to [answer questions](https://breez.technology/sdk/) and learn with you.

# **Liquid: Privacy with a Side(chain) of Bitcoin**

Unlike Spark’s tree-structured statechain, Liquid is a sidechain — a separate network that runs its own blockchain. It’s operated by a federation of functionaries who take turns proposing and signing blocks and managing the peg between BTC and its sidechain asset, L-BTC.

Although Liquid uses a wrapped form of bitcoin, its integration with Lightning is seamless. Through the Breez SDK, users can send and receive Lightning payments via submarine swaps between L-BTC and BTC, enabling fast, private, and cost-efficient transfers.

### **Confidential Transactions**

Privacy is one of Liquid’s biggest strengths. Through [Confidential Transactions](https://blog.liquid.net/guide-to-confidential-transactions/), the amounts and types of assets being transferred are hidden from everyone except the sender and receiver. This ensures strong financial privacy while maintaining verifiable transaction integrity. The privacy Liquid offers surpasses many other crypto solutions as well as virtually anything fiat and conventional fintech can offer.

### **Native USDT**

Beyond L-BTC, Liquid also offers native USDT support (issued by Tether). Just as the intersection between Liquid and Lightning is seamless, the Breez SDK performs seamless atomic swaps between USDT and L-BTC to make all assets on Liquid feel at home. Liquid also facilitates the creation of [new assets and tokens](https://docs.liquid.net/docs/liquid-features-and-benefits#asset-issuance-on-liquid), which could recommend it for remittance apps, in-game currencies, reward points, and attested assets.

### **BOLT 12 & BIP 353 Functionality**

The Breez SDK also makes Liquid compatible with new and useful Bitcoin innovations, like [BIP 353](https://bitcoin.design/guide/how-it-works/human-readable-addresses/) and [BOLT 12](https://bolt12.org/). Together, these innovations deliver a broad array of improvements from human-readable addresses and reusable payment requests to hidden IP addresses.

For more information, check out our [extensive documentation](https://sdk-doc-liquid.breez.technology/). If you want to take our Liquid implementation for a test drive, [try Misty Breez](https://play.google.com/store/apps/details?id=com.breez.misty&pcampaignid=web_share), our reference app to show just how beautifully Liquid flows.

# **The Only Wrong Choice Is Waiting**

As anyone who bought bitcoin last decade will tell you, bitcoiners love adopting early and enjoying first-mover advantages. Bitcoin is a young technology, and it’s changing the world. Lightning is younger, and it’s changing Bitcoin. Spark and Liquid are even younger, and they’re finally turning bitcoin into the peer-to-peer electronic cash the world has been waiting for.

Both of these technologies are strong candidates. Many apps would succeed with either one, though others might benefit from the particular advantages of one option or the other.

So, whether you choose Spark for its instant settlements and offline capabilities or Liquid for its privacy, the best move is to start building now because the future belongs to the devs who don’t wait for tomorrow.

Spark or Liquid? Building with the Breez SDK ⚡️

## **The World’s Building ⚡️**

![](https://substackcdn.com/image/fetch/$s_!u_0B!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F6e78bf0d-8bcd-4b3a-846a-3dffc31d01f4_3219x1811.jpeg)

We’ve been shouting it from the rooftops: [**it’s time to build**](https://www.time2build.dev/).

In case you’ve been off the grid, here’s the rundown. We launched [**</time2build>**](https://www.time2build.dev/) — a global developer challenge to bring bitcoin to existing open-source apps using the [**Breez SDK**](https://breez.technology/sdk).

Thanks to the support of our sponsors and bitcoin communities, the challenge has spread like wildfire across the globe. From Sofia to Hong Kong, Taipei to Kampala, Lusaka to Lugano, Tokyo to Amsterdam, builders everywhere are getting involved. India, Mexico, and beyond have also joined in — with the UK, El Salvador, Brazil, and South Korea up next.

If you’re a builder, now’s the moment. Jump in, build something that lasts, and help bring the utility of bitcoin to millions.

## **Bringin’ Bitcoin to Europe 🇪🇺**

![](https://substackcdn.com/image/fetch/$s_!K-KU!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F3d7f61da-feaa-4574-8664-8d65fac464e5_400x225.gif)

For Europeans looking to live on bitcoin, life just got a *little* easier. [**Bringin**](https://bringin.xyz/) has officially launched, helping anyone buy, sell, and spend their bitcoin.

We sat down with their founder, [Prashanth Chandrashekar](https://bringin.xyz/), who explained how the idea for the company came from experience when he moved from India to Estonia. He was paid in BTC but waited days to access euros. Holding bitcoin was easy. Using it wasn’t. So he built a way to change it.

After 18 months in beta, Bringin is now live, helping users pay rent, bills, and move value across borders. The European-based app is the latest to go nodeless with the [**Breez SDK**](https://breez.technology/sdk). No nodes, no channels, no liquidity headaches. Just an effortless integration for developers and a world-class experience for users.

It’s been a *busy* month.

Alongside the [**global meetups for </time2build>**](https://x.com/Breez_Tech/status/1978106473772122294/), our team has been on the road (and in the skies) spreading the good word of Bitcoin. First stop: Los Angeles. We kicked things off at [**Lightspark’s Sync**](https://www.youtube.com/watch?v=dLZTGMSGcXE), connecting with builders and innovators from across the tech world.

From there, Roy headed to Lugano for the [**Plan ₿ Forum**](https://planb.lugano.ch/planb-forum/), hosting an [in-person builder meetup](https://planbweek.com/) for **</time2build>** and joining panels at **Bitcoin Suisse**, **Arkade Day**, and the main event itself. There, he shared [how Lightning is becoming the common language of the Bitcoin economy](https://rumble.com/v70mlfs-wagmi-stage-lugano-plan-forum-2025-live-from-lugano-.html?start=28883) and later [joined Stephan Livera](https://rumble.com/v70mts4-day-1-stephan-livera-hosts-plan-b-podcast-in-lugano.html) to discuss what’s next for Breez.

# Helping Kiwis live on Bitcoin 🇳🇿⚡️

We sat down with Rob Clarkson, Co-founder and CTO of [Lightning Pay](https://lightningpay.nz/), to talk about how their team has built the best set of tools for stacking, saving, and spending Bitcoin across New Zealand.

## Simple Beginnings

Lightning Pay started with a simple goal: increase Bitcoin adoption across Aotearoa. What began as a way to help merchants accept BTC quickly grew into a platform where anyone can buy, sell, and spend Bitcoin directly from their bank — with full self-custody.

## Unleashing the Kiwi Spirit

Rooted in New Zealand’s “*number 8 wire*” spirit of innovation, Rob explains how Lightning Pay is helping Kiwis protect their wealth: Bitcoin only, no distractions. Their agile team is bringing together all the financial tools Kiwis need to stack, save, and spend in one place.

## Going Nodeless with Breez

When it came to adding Lightning, Lightning Pay went [nodeless with the Breez SDK](https://breez.technology/sdk), calling it a developer’s dream. It removed the complexity of running nodes, managing channels, and handling liquidity, allowing the team to focus on building the best user experience and growing adoption across New Zealand.

Here’s Rob’s story 🎧

## Helping anyone in the world move value with Lightning ⚡️

We sat down with [Prashanth](https://x.com/prashanthc123), Founder & CEO of [Bringin](https://bringin.xyz/), to talk about how they’re making Bitcoin usable in everyday life.

Bringin’s goal is simple: help people live on Bitcoin. Buy and sell from any wallet, spend even when a merchant doesn’t accept BTC, and send or receive value anywhere in the world.

### Like most products, the idea was born from a problem. 

When Prashanth moved from India to Estonia, he was paid in BTC but waited days (sometimes weeks) to access euros while banks made the whole process a nightmare. For Prashanth, holding Bitcoin was easy. Using it? *Not so much*.

### It was from that frustration that the spark for Bringin was born.

They’ve spent the last 18 months focused on building the best experience for users in beta, and have now gone public, helping Bitcoiners across Europe use Bitcoin the way they want to: from paying rent and bills to moving value across borders.

### And to deliver the best UX with an effortless developer experience, Bringin went nodeless with the [Breez SDK](https://breez.technology/sdk).

The whole build took just “*two to three weeks*,” avoiding the headaches of building on Lightning. No node setup, no channel management, no liquidity issues. Just value moving freely from one person to the next, leaving the Bringin team free to focus on building for real-world adoption.

Here’s Prashanth’s story 🎧

## **The Utility of Bitcoin? Moving Value Like Information ⚡️**

![](https://substackcdn.com/image/fetch/$s_!UhSm!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F530a354d-9e7d-4b2e-bf95-8b4f8cf647d9_1280x800.png)

Last month, Roy was busy putting words to what we’ve all been feeling.

Yes, we all know Bitcoin is the best asset. But there is a bigger opportunity, one that can transform our lives just like the internet has done for billions around the world.

In his latest piece, published on Bitcoin Magazine, [*The Utility of Bitcoin: Moving Value Like Information*](https://blog.breez.technology/the-utility-of-bitcoin-moving-value-like-information-2513eae84676), Roy explains how Bitcoin’s real innovation is not payments but **value transfer**, the ability to move value directly, freely, and without intermediaries. Just as the internet made information flow, Bitcoin is doing the same for value.

He describes how fintech and stablecoins still depend on permissioned systems, while Bitcoin, Lightning, and a growing ecosystem of subnetworks such as Spark, Ark, Liquid, and Fedimint are together enabling a new era of peer-to-peer value transfer.

It is a deep dive into how Bitcoin’s utility is redefining how value moves online and how apps are becoming the engines of that change.

## **It’s Time to Build on Bitcoin ⚡️**

https://storage.googleapis.com/geyser-projects-media/grants/round-016/time2build.webp

This week the world stepped up to answer the call as we launched [</time2build>](https://www.time2build.dev/), a global developer challenge to bring bitcoin to the open-source apps used by millions.

Together with our friends at [Tether](https://tether.io/), [Lightspark](https://www.lightspark.com/), [Plan ₿ Network](https://planb.network/en), [Fulgur Ventures](https://fulgur.ventures/), [Draper University](https://draperuniversity.com/), [Pleb Lab](https://www.pleblab.dev/), and [Geyser](https://geyser.fund/grants), we are inviting developers everywhere to help move value like information and build the next era of our online lives.

From Lagos to London, and Buenos Aires to Tokyo, more than **50 communities** have joined the global grassroots movement, sharing the challenge with members and hosting in-person meetups.

And a quick reminder: this is not a hackathon or a bounty. It is an ambitious experiment to accelerate bitcoin adoption in the apps we use every day, rewarding only merged code and the developers who work hand in hand with project maintainers.

So why now? [Lightning is becoming the common language of the Bitcoin economy](https://medium.com/breez-technology/lightning-is-the-common-language-of-the-bitcoin-economy-eb8515341c11). Subnetworks are growing. And the tools are finally ready, with the [Breez SDK – Nodeless](https://sdk-doc-spark.breez.technology/) making it simple for any developer to add bitcoin to their app.

Stay tuned as we spotlight submissions, partners, communities, and some seriously awesome projects in the weeks ahead. So whether you are merging code, mentoring devs, or just cheering them on...

***It’s time to build*** ⚡️

## **It’s Graduation: Welcome Class of Q3 🎓**

https://miro.medium.com/v2/resize:fit:1400/format:webp/1*LcJ8HBQNFuI_hrZprGWeZg.jpeg

As Q3 comes to a close, we’re welcoming a new class of bitcoin-powered apps built with the Breez SDK. This cohort marks a series of milestones worth celebrating.

[SwapSo](https://www.swapso.io/), a bitcoin super app built in India, went live just **five days** after downloading the Breez SDK. Yes, ***FIVE DAYS***. That’s how quickly builders can go from idea to production with Breez.

Meanwhile, [Bitnob](https://bitnob.com/), [Open Wallet](https://www.openwallet.com/), and [SatGo](https://satgo.io/) became the first partners to integrate with the newest [Spark implementation of the Breez SDK](https://sdk-doc-spark.breez.technology/), making it faster and simpler than ever to add bitcoin to any app.

Honestly, this class has it all: AI assistants charging by the second, family apps teaching kids to stack sats, and chat platforms turning conversations into payments. It shows the full range of what’s possible with the Breez SDK.

So without further ado, meet the [Breez SDK Class of Q3 2025](https://blog.breez.technology/the-breez-sdk-class-of-q3-2025-565356ef4335): [AvatarTalk.ai](https://avatartalk.ai/), [Bitnob](https://bitnob.com/), [BTCBitByBit](https://launch.btcbitbybit.com/), [EvoMone](https://www.evomone.com/), [Open Wallet](https://www.openwallet.com/), [RETI](https://reti.tech/), [SatGo](https://satgo.io/), [SatSails](https://www.satsails.com/), [SwapSo](https://www.swapso.io/), and [ZapLN Bot](https://github.com/musa-42/Zap_lnbot).

What’s next? Well, the next class is already forming and builders everywhere are making value move like information ⚡️

## **Nodeless on Spark Goes Public 🔥**

https://breez.technology/breez_spark.png

The wait is over. The **Breez SDK – Nodeless ([Spark implementation](https://sdk-doc-spark.breez.technology/))** is now open to everyone.

This marks a new chapter for builders everywhere. With our Nodeless SDK, developers can bring bitcoin to any app effortlessly, without the headaches of running a node, managing channels, or paying setup fees.

For anyone who missed the memo, **Spark** is a Bitcoin-native Layer 2 built for speed, scale, and simplicity. It powers real-time, low-fee, self-custodial payments and supports Bitcoin-native assets such as stablecoins. And we’re bullish.

Whether you are building a wallet, a social app, or an entirely new kind of product, the **Breez SDK – Nodeless** gives you the freedom to build with bitcoin in just a few lines of code.

What are you waiting for? [**Add bitcoin to your app today**](https://sdk-doc-spark.breez.technology/) ⚡️

## **Lightning in the Wild (Again)⚡️**

https://ml.globenewswire.com/Resource/Download/6e9267ee-a57c-4d36-a6f7-ab3c921e2edc/unknown-3.png

Spotted ***again*** in the Bitcoin rainforest: the Brazilian-born [**Klever Wallet**](https://klever.io/) just expanded its Lightning superpowers.

Earlier this year they added Lightning to their wallet, and now it powers their swaps, bringing instant, low-cost, and secure bitcoin swaps straight to users — another reminder of how flexible the Breez SDK can be.

This herd is growing fast, keep your eyes peeled for the next sighting 🔭

It’s been another busy month for Breez. The </time2build> launch had people talking, with features in [Bitcoin Magazine](https://bitcoinmagazine.com/business/breez-lightspark-and-tether-launch-time2build-global-hackathon-with-25k-in-prizes-to-boost-open-source-bitcoin-integrations), [Cointelegraph](https://cointelegraph.com/news/breez-and-partners-launch-time2build-to-incentivize-bitcoin-integration), [Lightning News](https://t.co/LpBApnTqsS), and Atlas 21. Danny from the Breez team also joined [#CHAINREACTION](https://x.com/Cointelegraph/status/1975563635394290070) with Robert Baggs and Gareth Jenkinson from Cointelegraph to unpack the challenge and what it means for builders.

![](https://substackcdn.com/image/fetch/$s_!5lCq!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F473bb1ae-7f19-425b-8478-ea9f415bedce_800x672.png)

Roy has also been active on every front. In addition to publishing [*The Utility of Bitcoin: Moving Value Like Information*](https://blog.breez.technology/the-utility-of-bitcoin-moving-value-like-information-2513eae84676) in Bitcoin Magazine, he released [a new piece](https://bitcoinmagazine.com/print/ark-and-spark-the-channel-factories-print) on channel factories, exploring how Ark and Spark revive the promise of channel factories, cementing Lightning’s central role in Bitcoin’s future. He also joined the [Mr. M Podcast](https://www.youtube.com/@MrMPodcast) to discuss Lightning and where AI could intersect with Bitcoin’s evolution, and spoke at [Infobip’s Shift](https://x.com/Breez_Tech/status/1967633175389278450) in Croatia about life building a Bitcoin startup.

![Image](https://substackcdn.com/image/fetch/$s_!CSlM!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2Fe2997835-1ec3-43a9-8552-42d5f8f1510c_4096x2736.jpeg)

And it’s not just Roy. Breez’s very own Ivan Makedonski was featured in Bitcoin Magazine’s Lightning Issue with [*Lightning Strikes: The Value-for-Value Future of Money and Work*](https://bitcoinmagazine.com/print/lightning-strikes-future-value-for-value), exploring how Lightning will reshape how we earn, spend, and create value online.
