@ErickRomeroEdda put together on our @MidnightNtwrk Summit–winning RWA tokenization project (https://t.co/ghP6AmdxIr) - 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.

If you're interested in this space, I'd highly recommend checking these out 👇

[Brick Towers @BrickTowers]

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.

If you're building on @MidnightNtwrk this developer focused wallet helps you ship faster. For wallet builders I hope this offers you insights into the wallet-sdk

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.

@solidsnakedev @BrickTowers You're probably using an image: "bricktowers/proof-server:6.1.0-alpha.6", this image does not have parameter files, true. I was referring to https://t.co/3uB7ZeLOnq which was fixing the issue with missing parameters file you had, it requires you baking those parameters manually.
