Midnight Network is live and is supported in @urbleapp
urble is the first ever mobile app running on Midnight Network. In addition to the simple, fun and impactful saving for yourself or friends on other blockchains, it lets you hold, send and receive shielded assets in complete privacy on @MidnightNtwrk. Thank you @midnightfdn for all the support.

The good thing about money is that it becomes more meaningful when it is connected to someone you care about.
Across the EU, young people left their parental home at an average age of 26.3 in 2025. In several countries, the average was above 30. For millions of European families, financial support continues well into adulthood.
"Saving for Others" in this economy is a must.
You could create a goal for your child, partner, parent or friend, automate contributions and invite other people to participate.
A university fund built by parents and grandparents.
An emergency buffer shared between siblings.
A first-home goal funded as a couple.
Every contribution has a purpose. Everyone can follow the progress and saving becomes something you experience together.
This is the urble way to save.
@ErickRomeroEdda put together on our @MidnightNtwrk Summit–winning RWA tokenization project (github.com/bricktowers/midni…) - it's really worth a watch.
It’s one thing to build something, but it’s especially rewarding when someone takes the time to really dive into it and share it with the community.

Excited to demo @urbleapp at the latest Midnight Dev Hang.
We’re proud to be at the forefront of what @MidnightNtwrk is enabling: a real mobile experience that abstracts away so much of the underlying complexity and makes privacy-first finance far more usable.
With urble, users can focus on goals, savings, and money movement, without blockchain friction.
Big thanks to @midnightfdn for the platform and collaboration.
urble is live — try it out and send us feedback. We’re building fast and would love to hear what you want next.

Partnership Announcement
The @Cardano_CF, @BrickTowers, and DFX are joining forces to bring @Cardano into everyday use.
With Cardano now integrated into @OpenCryptoPay, users will be able to pay with $ADA in 137 SPAR supermarkets across Switzerland, instantly, directly, and without relying on centralized exchanges. Merchants benefit from low fees making crypto payments commercially viable at scale.
With @urbleapp, Brick Towers shows what practical crypto adoption looks like: users can save ADA for others and use it for everyday payments at @SPARInt - combining regulated infrastructure with real-world usability.
This partnership marks a major step toward real-world blockchain adoption, where crypto meets daily life.

@BrickTowers × @DFX_swiss powering CHF & EUR onramps for urble
We’re excited to partner with DFX, who now power the fiat onramp for @urbleapp – enabling seamless access from traditional banking to on-chain assets, directly in-app.
A key step toward making on-chain savings and shared financial contracts accessible to more people.
Sergey Kisel retweeted
2025 was a year of real progress for urble.
From governance to product, research to real users:
– urble Association launched
– MVP built and publicly demoed
– @CV_Labs Cardano Accelerator
– Research with @ZHAW, @UZH_en & @hslu
– App launched, first users onboarded
– @MidnightNtwrk Summit Hackathon win
Each step moved us closer to building a self-custodial, long-term savings infrastructure designed to last.
