We teased V3 last month. Today, it’s live.

Umbra V3 is now open on @CantonNetwork DevNet.

Connect your Devnet wallets, (preferably, Loop or Console wallet). Invite dealers to compete privately. Fill your trade across one or more dealers and settle atomically.

Your wallet. Your signatures.

Enter → https://t.co/leVcy4qmWH

DevNet assets only.

V3 is close!!

You'll bring your own wallet, and Umbra will never hold your key.

⚙️ Decentralization should be something you can test

That’s what @BitSafe_Finance pushed in #HackCanton S3.

50K canton-network:native across LocalNet contributions and the Decentralized Party Gold path.

Big respect to the builders who took it on — and to BitSafe for backing the challenge 🤝

Coming back after taking silver to push Umbra even further is a major flex. Cross-team integration goes hard!!

🤝 #HackCanton S3 doesn’t happen in a vacuum

Big thanks to @BitSafe_Finance for backing the season, and to the partners supporting builders along the way:

@CantonFdn
@metatarzxyz
@grofty_labs
@Oneswapcc
@hackenclub
@procur3
@Hashlock_

From infra to wallets, liquidity and security — the goal was simple:

help builders ship.

Now → judging.

Two weeks on, same 7 days window from $9,409 → $13,503, and this is after the public release of Umbra's V3😁.
But the number I care about is underneath it, I mean the average block went from ~$672 to ~$2,250. Fewer trades, bigger ones. That’s what a block venue is supposed to do!

The V3 featuring the Bring Your Own Wallet, is now live👀

Last season, Umbra took silver at HackCanton. This season, I came back to push umbra even further.

The highlight, was working with BitSafe to settle a trade while my own participant was offline, via their DecMan, and getting to work through a real integration with another team made a huge difference for me.

Thanks to Richard and @BitSafe_Finance as a whole, for working through the co-hosting and the node-down test with me, and the @appsfactory_cc crew for their constant reminder (always pushed me back to building lol😅).

So yeah, now I want people to try it:

Our codebase is currently private; access can be arranged if needed.

Umbra cofounder breaks down the problem we’re solving, how private RFQs work, and why Canton makes this kind of market structure possible.

A quick look at what we’ve built and why it matters for institutional block trading.

[umbra @UmbraOnCanton]

Big orders move markets. Unless nobody sees them.

UMBRA is a dark OTC venue on Canton. Ask only the dealers you choose, take the best firm quote, settle on-ledger. The market sees nothing.

Live on DevNet.

[AppsFactory by NODERS @appsfactory_cc]

Real trades and wallets live on @CantonNetwork is top tier energy. Umbra is shaping up nicely. Respect for the grind!!

[umbra @UmbraOnCanton]

@0xGenZero Closed testing. Real activity.
Just getting started😉.

[⓪x🅖🅔🅝🅉🄴🅁🄾 @0xGenZero]

$9,409 in volume. 14 trades. All in closed testing.
We’ve been quietly stress-testing @UmbraOnCanton with a small group before opening access more broadly.
Seeing actual trades, wallets and dealer activity moving through the platform is a nice milestone.
We’re still early, but Umbra is starting to feel very real👀. @appsfactory_cc @CantonNetwork

Engineers challenging AI live? This is the meta. If you're serious about Web3 security, you need to watch this. Happening tomorrow!!

A trading rule that exists only in the front end is a suggestion.

Expiry, quote firmness and one-winner enforcement on Umbra live deeper than the interface.

Try out umbra today to witness this. Oh, and v3 is coming soon.

@Captain_snowboy Really soon👀

Large trades have a visibility problem.

They show the whole order publicly and the market gets to react before the trade is done.

For institutions moving size, privacy is not decoration. It is part of market structure. Which is why we're building Umbra
