Just a few short months ago, we convened to celebrate a rite of passage, when the first class of Breez SDK graduates 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.

Like a bare voice harmonizing with an acoustic guitar, there’s nothing as good as simple things done well. That’s Bitmo: 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.

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 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.

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’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.

As DIDx 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.”

Where mobile bandwidth is scarce, users need light, nimble apps. Grimm 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.

As detailed in our extended profile, Klever 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.

All shoppers like a slick webshop experience, but what about the merchant’s side? Loom21 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.

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 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.

Maybe orange pills would work even better if they were delicious? ordermoon 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 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 just couldn’t resist sharing the news of their launch this month.

The Tokyo Bitcoin Base 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.

Governments like money, and governments like borders, but money doesn’t like borders. It’s complicated. Yolat 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.
