bitcoin

#### Bitcoin doesn’t need to be explained. It needs to be experienced. 💥

In this episode of [Shoot the Breez](https://youtube.com/playlist?list=PLU5Dk7xLNHcSP3KmRyFJg4S64UrWPsT8-&si=4TwQ55KKlUT1GTD2), we speak with Francisco Chavarria, CEO of [Yopaki](https://www.yopaki.com/r/stagg), a product rooted in Mexican tradition and built for everyday use. Yopaki blends games, onboarding, and payments into one seamless journey.

Francisco’s bitcoin journey didn’t start conventionally — it was his dad who orange-pilled him. That spark changed his path, eventually leading him to Austin, where he connected with like-minded builders at places like @PlebLab. It was through that community that he met his co-founder, Carlos Chida, and the idea for Yopaki began to take shape.

For the two Mexican-born founders, the frustration was clear: exchanges were everywhere, but the mission was missing. Bitcoin was being buried in noise: *speculation, distractions, hype*. They saw a gap.

*So they flipped the story.*

They put bitcoin at the center of the product, but culture at the front. To reach people, they had to show that bitcoin was for them too. They started with something everyone already knew: Lotería. A beloved game played across generations. Only now, the prize is sats.

From there, they never looked back. After joining [Wolf's](https://wolfnyc.com/) bitcoin accelerator, Yopaki kept growing. With Lotería and Lightning powered by the Breez SDK, they’ve now made it possible for anyone to become a bitcoiner in minutes — in Mexico and beyond.

Here’s Francisco’s story.

### **The Breez SDK: the Class of Q2 2025**

https://cdn-images-1.medium.com/max/1600/0*xqRo-OOht4xxTHjm

Just a few short months ago, we convened to celebrate a rite of passage, when [the first class of Breez SDK graduates](https://blog.breez.technology/the-breez-sdk-class-of-q1-2025-1238ef1a5a98?source=collection_home---4------1-----------------------) went live and joined the Bitcoin economy. Today that rite repeats, but with a new class of intrepid, innovative, transformative graduates.

As their predecessors discovered before them, today’s SDK partners have learned how simple it is to implement and their users are rapidly learning to cherish the effortless UX. Perhaps that is why each quarter brings a new broad class of inspiring graduates, representing a wide spectrum of verticals and business models. Each of these vibrant young apps reinforces bitcoin’s incomparable utility as universal money and the value of the Breez SDK as the easiest way for developers to give their users the power of bitcoin payments.

So once again, let us congratulate our new graduating partners on taking the step of integrating bitcoin and giving their users opportunities and utility that no other technology could achieve.

Without further ado, it is my honor to present the Breez SDK Class of Q2 2025.

### Bitmo

**As Simple and Economical as a Bitcoin UX Can Be**

https://cdn-images-1.medium.com/max/1600/0*OaoZM2ryALECD266

Like [a bare voice harmonizing with an acoustic guitar](https://youtu.be/hSnuyoo_RCU), there’s nothing as good as simple things done well. That’s [Bitmo](https://www.bitmo.me/#home-section): a bitcoin app that lets users buy, sell, and send bitcoin with a three-step onboarding process, a super simple UI, and no fees beyond those collected by third-party processors. Bitmo is as good as it is simple.

### Bitpost

**Spreading Private Bitcoin Payments throughout E-commerce**

https://cdn-images-1.medium.com/max/1600/0*qYkRu3g0jZRzKSSu

Bitcoiners are ahead of the curve and don’t want to wait for e-commerce to catch up, so what’s a bitcoiner to do when they want to buy something from a webshop that only accepts fiat (icky!)? [Bitpost](https://x.com/bitpostP2P) has built a platform that lets bitcoiners post wish lists of purchases they’d like to make for other users to view, buy, and send back to the bitcoiners privately in exchange for bitcoin. Thanks to the Breez SDK, the whole system runs privately, secure, and without third parties.

### Brio

**Flattening the Onramp to Crowdsourced Saving on Telegram**

https://cdn-images-1.medium.com/max/1600/0*iZY8LYzoIyVgB2bu

A stokvel is a private, invitation-only credit union where everyone saves together and then disburses the savings to a different, rotating member. Some people may have never heard of them, and some will be amazed that everyone doesn’t use them. Building a frictionless gateway to bitcoin-based stokvels on Telegram is [Brio](https://x.com/BTCBrio_bot)’s raison d’etre. Giving bitcoin n00bs a way to enjoy a financial service on a messaging app that they’re using anyway is perhaps the easiest way to introduce them to bitcoin’s benefits.

### DIDx

**Leapfrogging Legacy Money in Emerging Markets**

https://cdn-images-1.medium.com/max/1600/0*xKMyVktk1Atk-u5C

As [DIDx](https://www.didx.co.za/index.html) notes, the internet was built without an identity layer, which is more of an obstacle where state bureaucracies are weak. That’s why DIDx has been helping people in such emerging markets to obtain reliable and secure digital identities, and once you have stable digital identities, adding payment functionality is a natural step. Looking back on their experience with the Breez SDK, DIDx had this advice for incoming freshmen: “Give it a go. It’s surprisingly fast to get started, and the developer experience is top-notch.”

### Grimm App

**Mobilizing Bitcoin in Africa**

https://cdn-images-1.medium.com/max/1600/0*pEmW5Qvi4fkNQe5F

Where mobile bandwidth is scarce, users need light, nimble apps. [Grimm App](https://usegrimm.app/) is a bitcoin wallet optimized for low bandwidth, and it lets users make and receive bitcoin payments with seamless conversion to three African fiat currencies. It even lets users top up their mobile data on the fly with a single tap.

### Klever

**Big-time Crypto Operator Goes Lightning**

https://miro.medium.com/v2/resize:fit:1400/format:webp/1*4-wyV9DZWqcL7FtEeCuIsw.png

As detailed in [our extended profile](https://blog.breez.technology/klever-wallet-bringing-lightning-to-crypto-with-the-breez-sdk-25b2be2a5e7b), [Klever](https://klever.io/) is a big-time crypto operator, offering their >100,000 monthly active users access to >1500 currencies in their hardware and software wallets. That’s why we were especially honored when Klever opted for the Breez SDK to give all those users access to bitcoin on Lightning. As you would expect, the fun-loving geniuses at Klever waited until after the surfing season to launch this past May.

### Loom21

**Showing E-commerce Merchants What Bitcoin Can Really Do**

https://cdn-images-1.medium.com/max/1600/0*vgoiobMHj9Py1951

All shoppers like a slick webshop experience, but what about the merchant’s side? [Loom21](https://loom21.com/en/) has built an app that lets merchants automatically manage their inventory, book sales, print receipts, and make and receive payments. Until now, those payments have had to be in fiat or on-chain bitcoin, but thanks to the Breez SDK, Loom21 can now accept more economical Lightning payments, giving merchants a backend as slick as the frontend their customers see.

### Mooze Labs

**Bitcoinizing Brazilian Payments**

https://cdn-images-1.medium.com/max/1600/0*HYwXimt2nMnZ7YXy

Digital payments in reais go over the Pix network, managed by the Central Bank of Brazil. In order to open Pix to crypto in general and bitcoin in particular, [Mooze Labs](https://mooze.app/) has built DePix — a stablecoin that enables frictionless transactions between reais, USDT, LBTC, and BTC, with the Breez SDK under the hood. If using bitcoin is the goal of self-custodial finance, Mooze is Raphinha’s left foot, shooting millions of Brazilians into the championship.

### ordermoon

**Satisfying Appetites for Bitcoin in Bulgaria and Beyond**

https://cdn-images-1.medium.com/max/1600/0*KEL4qJRrWMCJiFGR

[Maybe orange pills would work](https://blog.breez.technology/orange-pilling-has-stopped-working-4a407252c7a3) even better if they were delicious? [ordermoon](https://ordermoon.com/) unabashedly evangelizes for bitcoin and a circular economy, but they’ve realized that the way to a user’s heart goes through their stomach, so they have built a full-service, bitcoin-based, food-delivery app to foster bitcoin transactions among restaurants, drivers, and hordes of hungry bitcoiners. Thanks to the Breez SDK, restaurants using ordermoon can manage customer orders, their own or third-party drivers, and the bitcoin payments that keep the food rolling.

### Sorted

**Breaking Down Hardware Barriers and Bringing Bitcoin to Everyone**

https://cdn-images-1.medium.com/max/1600/0*WpfLmkvIow73OjDD

[Sorted](https://www.sortedwallet.com/) is a self-custodial bitcoin wallet that runs on feature phones, of which there are hundreds of millions in use worldwide. To make this possible, they needed a way to deliver bitcoin that was computationally light weight, versatile, and easy to use. So of course Sorted opted for the Breez SDK. That up to a billion people will now have access to bitcoin thanks to this partnership is a big deal, which is why [Bitcoin Magazine](https://bitcoinmagazine.com/news/sorted-wallet-integrates-breez-sdk-to-enable-bitcoin-payments-on-feature-phones) just couldn’t resist sharing the news of their launch this month.

### Tokyo Bitcoin Base

**A Bitcoin Hub That Hasn’t Forgotten the Fun**

https://cdn-images-1.medium.com/max/1600/0*3TQSjJwW0Nu8ujG8

The [Tokyo Bitcoin Base](https://tokyobitcoin.space/en/?ref=btctimes.com) is a place where bitcoiners can work and play in snazzy co-working spaces and event locations. Part of the retro-chic appeal is an app that the TBB has built to let users make a cheki photo (an instant photo — think Polaroid) on a tablet, purchase on site, and print as a souvenir. In other words, one of the world’s most modern and dynamic bitcoin spaces couldn’t resist taking the Breez SDK for a spin, and the result is a beloved toy.

### Yolat

**Disrupting the Geography of Payments**

https://cdn-images-1.medium.com/max/1600/0*nIHezCEz3wWCz6ch

Governments like money, and governments like borders, but money doesn’t like borders. It’s complicated. [Yolat](https://www.yolat.com/) noticed the obstacles to sending money to and from Africa, and they realized bitcoin’s potential to overcome them. Building on the Breez SDK, the Yolat payment app has allowed tens of thousands of individual users and dozens of businesses to make cross-border bitcoin payments affordably and reliably.

# **The Breez SDK Empowers Sorted to Empower Everyone**

![](https://cdn-images-1.medium.com/max/1600/0*ULed-6ec4328Z2G9)

Bitcoin is the world’s only global currency, but *global* should mean more than just geography. If a technology is only available to those with family offices and concierge accounts, it won’t disrupt very much, even if it’s available in 190+ countries. The depth of bitcoin’s penetration matters just as much, if not more, than its breadth.

[Sorted Wallet](https://www.sortedwallet.com/) is on a mission to bring bitcoin to everyone, especially the 300 million people who use [feature phones](https://en.wikipedia.org/wiki/Feature_phone) and simple Android devices. Many users prefer these devices because they’re cheaper, but they’re also popular in many markets because they tend to be durable and unappealing to potential thieves. And though statistics are hard to find, it’s a fair guess that many of those with the simplest phones are among the world’s 1.4 billion unbanked adults —  those who arguably need bitcoin most.

As any Uber driver will tell you, if you want to take someone along for the ride, you have to meet them where they are. As the world shifts toward a bitcoin-based economy, where value moves as freely as information, Sorted is making sure no one gets left behind. That’s Sorted Wallet’s goal: democratizing bitcoin-ready hardware with the Breez SDK.

### Sorted Busts Barriers to Bitcoin with Breez

The Sorted team first dove into the feature-phone market after a chat with the dev team behind [KaiOS](https://en.wikipedia.org/wiki/KaiOS), the leading OS for feature phones. It became obvious that technology was turning into a barrier between the globe’s new money — bitcoin — and the people it is designed to serve. The question was how to overcome it.

When technology is the problem, it’s also often the solution. Lightning changed the economics of bitcoin and added new uses, but running a client node locally was still too demanding for many feature phones. Sorted’s team considered building a custodial bitcoin app but realized that would introduce new, mainly regulatory, obstacles. Besides, you don’t empower people by taking possession of their money.

[The Breez SDK — Nodeless](https://sdk-doc-liquid.breez.technology/) was made to order. It offers a very shallow learning curve for developers and effortless onboarding for end-users, and its computational and storage requirements are very light, so it purrs on feature phones and base-model Android devices. Crucially, the users retain control of their keys, which gives them real empowerment and financial freedom. The Breez SDK lets users and developers leapfrog legacy money and move value around the world or across a kiosk counter with the ease of sending a text.

And like a good teammate, the Breez SDK grows and evolves with the needs of our partners. It supports bitcoin as well as USDT. It’s also simple and flexible enough that Sorted Wallet devs can extend it with cool new features that their users need, like the merchant app that they’re developing to help every shopkeeper and market vendor become bitcoiners, and the WhatsApp bot to make cross-border remittances as simple as sending mom a selfie.

[Sorted Wallet](https://sortedwallet.com/)

### A Great Network Just Grew by 300 Million

Before opting for the nodeless SDK, the Sorted team looked at a range of other alternatives. They considered delegating channel and liquidity management to an LSP, but those issues are now simply expected to be obfuscated from the UX. You don’t get any bonus points for that. Like so many other developer teams, they were looking for the easy and frictionless experience of a custodial app with the autonomy and light regulatory footprint of self-custodied bitcoin.

The Sorted folks started asking around, and the Breez SDK “was highly recommended by some of our trusted connections.” (That’s a good network!)

Following that advice has given Sorted users — actual and potential, all 300 million of them — access to unstoppable, economical bitcoin payments. Wise decisions like that have also helped Sorted secure other votes of confidence, like [Tether’s recent investment boost](https://tether.io/news/tether-invests-1-5-million-in-sorted-wallet-to-enhance-financial-inclusion/). As a result, people without access to banks and constrained by borders can use bitcoin to move value where they want and how they want using the devices already in their pockets, starting in July.

And it’s not just about how many; it’s also about how. Sorted is increasing the quantity of people with access to bitcoin, but bitcoin also expands the range of ways they can exchange value, and what they can do with their money. Once money can move freely — without borders, delays, or third parties — entirely new use cases become possible.

# #008 Feel the Breez 

Apps everywhere are adding Lightning — bringing borderless, Lightning-fast, peer-to-peer Bitcoin payments to users around the world. And in the last month alone, over 100,000 people joined the Bitcoin economy through apps powered by the Breez SDK. Let’s dive in:

⚡️ Breez + Lightspark Join Forces
🚀 SDK Partners Go Live
💥 Nodeless Keeps Getting Better
🌬️ Lightning Made Easy with Misty Breez
🌍 Breez Around the World

## Breez + Lightspark Join Forces ⚡️

Breez is teaming up with Lightspark — making it even easier for developers to bring self-custodial Lightning payments into everyday apps and services.

We’ve just announced a new implementation of the Breez SDK on Spark — a Bitcoin-native Layer 2 built for speed, settlement, and scale. This implementation brings everything developers need to power Lightning payments: bindings for all major languages, support for LNURL and Lightning addresses, and more — unlocking new ways to use Bitcoin as a global, permissionless currency across use cases like streaming payments, monetizing social apps, in-game currencies, cross-border remittances, and AI micro-settlements.

As Roy put it:
> “We need developers to bring Bitcoin into apps people use every day. That’s why we built the Breez SDK. We’re excited to build on Spark’s revolutionary architecture — giving developers a powerful new Bitcoin-native option and continuing to strengthen Lightning as the common language of Bitcoin.”

As part of the collaboration, Breez will also join Lightspark as a Spark Service Provider to help scale the ecosystem. We’ll be sharing more details soon — with the new implementation set to launch later this year — so make sure to follow us for the latest.

## Breez SDK Partners Go Live 🚀

Another month, another 100,000 people with access to Lightning.

In May, more apps went live with the Breez SDK — bringing real-world Bitcoin payments to even more people around the world.

First up: Klever went live. With 100,000+ users across Brazil, Nigeria, India, and beyond, Klever’s mission is to make crypto accessible in underbanked regions. They’d been trying to add Lightning for years — but building it from scratch was far too complex. What they needed: effortless onboarding, no setup fees, zero channel management. That’s exactly what they found in Breez.

As Baiano, Klever’s CEO, put it:

> “Breez was the winger who crossed the ball into the middle for Klever to score.”

Also going live in May: Cowbolt, a team chat and cost-splitting app built for families, friends, and teams to split and settle payments. The team announced their public release at Bitcoin 2025 — powered, once again, by the Breez SDK.

Welcome to Lightning, Klever and Cowbolt⚡️

## Nodeless Keeps Getting Better 💥

The Breez SDK – Nodeless is our most popular implementation, and over the past month, we’ve added even more features for developers to deliver the best Lightning experience in their apps and services. The latest release brings complete support for both BOLT 12 and BIP353. Alongside this, Nodeless now also supports LNURL-Verify.

With everything you need for a world-class UX, you can now vibe-code Bitcoin payments into your next unicorn. Aljaz created context files for folks to use, so AI tools can work their magic. Check it out here → Context Files

And you don’t have to take our word for how easy it is now.

Here’s what a partner shared with us after using Cursor to add Bitcoin payments to their app:

> I was playing around the JS SDK and used Cursor AI and was able to build a functional secure self-custody lightning wallet in just a few hours. The documentation and the functionalities of the SDK is amazing! And it just works.👏

## Lightning Made Easy with Misty Breez 🌬️

As a result of the SDK improvements, Misty Breez now has complete support for BOLT 12 and BIP353 too. It’s also the first wallet to offer a customizable Lightning address that supports both BIP353 and LNURL.

That’s a lot of acronyms, we know — but here’s the short version: Lightning just got way more usable. And even better, any partner using the Breez SDK can offer the same experience. Plus, for freelancers and businesses using Zaprite, Misty Breez was announced as the latest integration to accept payments on the platform.

If you’re looking to learn more about Misty Breez, BTC Sessions dropped a new tutorial. In the (very) helpful video, he breaks down how the app works and explains why he believes it’s “as easy as Venmo.”


## Breez Around the World (In 31ish Days)

From pasta to panels, the Breez team’s been busy — spreading the word on what’s next for Bitcoin payments.

We kicked off May with our annual team offsite. The team made the trip to Italy, where we mapped out plans, ate incredible food, and attended the (excellent) Tuscany Lightning Summit. The summit brought together the brightest builders in the space to discuss the future of Bitcoin and Lightning — all in the picturesque seaside town of Viareggio. Bitcoin, Lightning, and pasta — wonderful.

Later in the month, Umi and Roy flew to Bitcoin 2025 in Las Vegas, with Roy taking the stage twice during the 3-day Bitcoin extravaganza. First, he joined a panel on the latest developments in Lightning, moderated by Jordi Montes (Fewsats), followed by a conversation on Bitcoin’s evolution from digital gold into an everyday currency, moderated by Stephan Livera.

That’s all for this month folks. We had a lot to share.

We’ll see you next month for more on what’s happening in Breez, Bitcoin, and Lightning.

Until then, remember: the best time to get into Lightning is now — it always has been.

See y’all next time ✌️

# Breez + Spark — A New Way to Build on Bitcoin

#### Breez and Spark are teaming up with a new Breez SDK implementation built on Spark’s Bitcoin-native Layer 2 infrastructure — making it even easier for developers to integrate self-custodial Lightning payments into everyday apps and services.

[Bitcoin is evolving from digital gold into a global currency used by millions worldwide](https://breez.technology/report) — and as this momentum continues to grow, more apps want to tap into its ability to bring permissionless peer-to-peer payments to anyone, anywhere.

That’s where Breez and Spark come in. Breez builds the services developers need to bring self-custodial Lightning payments to their apps. Spark is a Bitcoin-native L2 built for payments and settlement so developers can build natively on Bitcoin instead of around it.

**And now, Breez and Spark are joining forces.**

We’re excited to announce a new implementation of the Breez SDK, built on top of Spark, making it even easier for developers to add Bitcoin payments to everyday apps and services. The new implementation brings developers everything needed for a best-in-class Lightning experience — including bindings for all major programming languages and frameworks, support for LNURL and Lightning addresses, and real-time user interaction via mobile notifications.

Built on Spark, this implementation provides a Bitcoin-native experience without relying on bridges or external consensus. The new SDK implementation gives builders new ways to unlock the power of Bitcoin as a global, permissionless currency in various use cases like streaming payments for content, monetizing social apps, in-game currencies, cross-border remittances, AI micro-settlements, and many more. 

> “We need developers to bring Bitcoin into apps people use every day,” said Roy Sheinfeld, CEO of Breez. “That’s why we built the Breez SDK. We’re excited to build on Spark’s revolutionary architecture — giving developers a powerful new Bitcoin-native option and continuing to strengthen Lightning as the common language of Bitcoin.”

> “This is what the future of Bitcoin looks like — fast, open, and embedded in the apps people use every day. By teaming up with Breez, we’re expanding the ecosystem and giving developers powerful, Bitcoin-native tools to build next-generation payment experiences. Together, we’re building the standard for global, peer-to-peer transactions,” said Kevin Hurley, creator of Spark.

>“We’re excited to see what developers build with Spark; it’s very exciting to see this come to the world,” said David Marcus, co-founder and CEO of Lightspark.

As part of the collaboration, Breez will also operate as a Spark Service Provider (SSP) — alongside Lightspark — helping facilitate payments and supporting the growth of Spark’s ecosystem. The new implementation will be released later this year, with technical specifications to follow.

Breez SDK - Nodeless | WASM, Lowered Minimum Send/Receive, and More ⚡️

No, you have to be online to initiate the payment and claim the swap.

Today, Breez released a big update to the Nodeless SDK ⚡️

Check out the release notes for more details: https://github.com/breez/breez-sdk-liquid/releases/tag/0.8.0

***

## 1. WASM support
Nodeless now supports WebAssembly, so apps can now add Bitcoin payments directly into browsers and node.js environments.

To make WASM happen, we’ve made major improvements across the SDK.

⚠️ *Warning: we’re about to go technical* ⚠️ 

WASM-Compatible SDK Core
We updated the 𝚜𝚍𝚔-𝚌𝚘𝚖𝚖𝚘𝚗 crate to work in WASM environments by:
→ Integrating a WASM-compatible gRPC client using 𝚝𝚘𝚗𝚒𝚌_𝚠𝚎𝚋_𝚠𝚊𝚜𝚖_𝚌𝚕𝚒𝚎𝚗𝚝
→ Implementing custom DNS resolution for WASM
→ Refactoring the internal REST client to remove non-WASM-compatible dependencies
→ Introducing a new 𝚜𝚍𝚔-𝚖𝚊𝚌𝚛𝚘𝚜 crate for shared macro support across platforms

New WASM-Specific Crate
We added a dedicated WASM interface using 𝚠𝚊𝚜𝚖-𝚋𝚒𝚗𝚍𝚐𝚎𝚗, with custom type and callback handling to provide a smooth developer experience.

Flexible SDK Customization
 The new 𝙻𝚒𝚚𝚞𝚒𝚍𝚂𝚍𝚔𝙱𝚞𝚒𝚕𝚍𝚎𝚛 makes it easy to configure SDK components:
 → Includes platform-specific filesystem abstractions
 → Supports persistent storage in both Web and Node.js environments

SQLite and Cache Handling
 Since traditional databases are challenging in WASM, we:
 → Use an adapted in-memory SQLite setup via 𝚛𝚞𝚜𝚚𝚕𝚒𝚝𝚎
 → Added a custom persistent watcher to handle state

Background Tasks & System Adaptations
We implemented WASM-friendly alternatives for:
 → Background task spawning
 → Interval management
 → Accessing system time

Alternative Blockchain Data Sources
 Electrum isn’t viable in-browser, so we:
 → Integrated support for 𝚆𝚊𝚝𝚎𝚛𝚏𝚊𝚕𝚕𝚜 as a lightweight blockchain data source

WASM-Ready Boltz Integration
 → We refactored the Boltz swap client to be fully compatible with WASM environments.

gRPC-Web Proxy Support
 All gRPC-based services (e.g., Breez Server and real-time sync):
 → Now support 𝚐𝚁𝙿𝙲-𝚆𝚎𝚋 proxies
 → Enabling full connectivity from browser environments

## 2. Lower Minimum Send/Receive Amounts

We’ve significantly lowered the minimums for sending and receiving payments with the Breez SDK - Nodeless.

You can now:
> ➡️ Send from just 21 sats
> ⬅️ Receive from just 100 sats

## 3. Pay Fees with Non-Bitcoin Assets

Users can now pay fees without using Bitcoin — instead paying fees with other assets like USDT.

A smoother UX for your users — more flexibility for your app.
