Union Community Call: September 2025

The September Union Community Call begins in 30 minutes. See you there ↓

Union is NOT at risk from the massive industry-wide NPM supply chain attack. We use @nixos_org for fully reproducible builds. This means that we know byte-for-byte exactly what will be included in our builds. The Nix level sha256 of our NPM dependencies has not been altered in

First Community Call of mainnet. Union’s monthly Community Call is back tomorrow, Tuesday, 9th September at 4PM UTC. Join to get the latest updates and hear what’s coming next. zkgm. https://t.co/0YEqrkebB5

We’re excited to announce that Escher has successfully raised its Pre-Seed round! Backed by @union_build, @babylonlabs_io, ECHO, leading validators, and world-class angels, this marks a strong foundation for our mission: Bringing order to chaos — through abstraction, liquidity,

ZK interop is the future. Congrats to @union_build on mainnet launch.

But it's the end of this thread. zkgm.

5/5 The road is long, but it will be conquered. Together. https://t.co/UczSNDXfdb This is only the beginning.

4/ More ways to get involved are dropping soon. It's never been a better time to be a goblin, a whale shark, or anything in the Union Army. (Big things are coming for the whale sharks btw.)

3/ Goblins don't celebrate for long. They yearn for the grind. Join the Discord, and get active https://t.co/ym9bUitVHL. Send devs to https://t.co/ngUAbJwj5Q and https://t.co/rZJGsgfQtM. Write threads, write articles, record videos, make memes. Spread the word.

2/ The Union Army is as important now as its ever been. People will find out about Union. Welcome them. People will want to build with Union. Tell them how. People will want to learn about Union. Educate them. People would be excited about Union, if they only knew. Find them.

1/ Mainnet is just the beginning. You've heard it, but what does it mean? It means that mainnet is a step on the road, not the end of it. Union's mission is to solve interoperability. There's still plenty of work left to be done, and lots that needs to be built to get there.

This is just the beginning. Union Army, assemble!

Congrats to @UnionFDN on the mainnet launch 🔥 Babylon Labs and Union share the same mission: scaling trustless infrastructure that unlocks the next era of crypto. With zk interop live and Bitcoin staking growing, the foundations of a secure, multi-chain future are being built

Most BTC in DeFi today is not really BTC. It’s wrapped, bridged, or sitting in someone else’s custody. That means risk: hacks, exploits, and trust assumptions everywhere. BUT, what if your Bitcoin could stay on Bitcoin and power DeFi?

This is just the beginning. We’re already back to building as if it’s any other day. No more distractions. zkgm to the real @union_build community.

Some of the eagle eyed amongst our community may have noticed that this video, as well as some of the visual images for Mainnet look a bit different than the classic Union aesthetic you have grown used to seeing. Well for the past month or so, We have been working on the future🧵

Interoperability is crucial to crypto’s future, but solutions to date have largely fallen short. Union is pushing to make interoperability practical at scale. [Sponsored]

Congratulations to the enture @union_build team and community. Cool tech that will connect many chains into the future.
