Hey, that's us! We're proud to have Umbra accepted as part of @OctantApp's latest Privacy Round, starting tomorrow at 12 UTC. If you've ever benefited from our onchain privacy work do consider donating. $20 USD is all it takes!
Replying to @OctantApp
@UmbraCash: the reference implementation of stealth addresses on @ethereum, from the team that co-authored ERC-5564 and ERC-6538.

We’re unironically humbled, honored and proud to announce 127 people backed us in @OctantApp's Epoch 13! Turns out privacy requires B2B sales too. Paraphrasing Eric Hughes, we must better sell people on privacy if we expect to have any. Time to lock in on Umbra v2. Onward.
We're humbled, honored and proud to announce that Umbra has been selected for @OctantApp's Epoch 13. What has this taught us about B2B sales? Nothing. We build open source privacy tools. It's time to fund privacy.

Dang y'all, thanks. Extremely grateful for the support. It truly means a lot. Time to get (back) to work!

Private payments. Public support. Thank you to our 127 backers and kudos to @OctantApp and the @GolemFoundation for making it possible to fund privacy as a public good. Umbra v2, here we come!
What an epoch! Thank you for contributing to advancing privacy on Ethereum and the open internet. Your allocations have helped allocate 100 ETH in matching funds from @GolemFoundation. A big congrats to all the teams in the cohort. Thank you for all your work. Here's to a future where privacy is the default and not the exception.

It's the final countdown indeed. Thank you to everyone who’s backed Umbra, shared our posts or nudged a friend this week. And kudos to @OctantApp and the 12 other teams for making this a real community effort. Still a few hours left to cast your votes!
13 privacy projects. One very public deadline. 5 hours left to back your favorite teams in @OctantApp's Epoch 13. The 100 ETH matching pool has been unlocked, but every extra vote still counts! Help us ship Umbra v2 and realize the untapped potential of stealth addresses.

Privacy is multiplayer. It works best when everyone helps preserve it. Thanks to @OctantApp, we met the Curvy team & began exploring how Umbra payments could flow directly into @0xCurvy’s private pool, extending privacy beyond the receiving addr. Here's to more fusion dances!
Privacy works better when protocols compose. Curvy reduces the public link to the payer. Umbra gives the recipient a fresh stealth address. We’ve been exploring what happens when those two flows connect. Still a concept for now, but this is the direction we’d like privacy infrastructure to move in. Final day of @OctantApp Epoch 13. Explore the round and vote for Curvy, Umbra, or any privacy project you believe in. epoch.octant.app/rounds/0x57…

Legitimately blown away by the level of support we've received so far. Thank you! This will make a difference in our resource allocation, and allow us to get Umbra v2 over the finish line. If you're able to contribute, and you haven't yet, please consider.
At @ScopeLift, we've been working on @UmbraCash since 2020. It's open source privacy tech that we've built solely from grant funding. We don't monetize it. It's a public good. Please consider supporting the project in the ongoing @OctantApp round. epoch.octant.app/rounds/0x57…

Our co-founder @BenDiFrancesco explains why AI just made everyone an easier target. Think no one would bother tracking you down? AI made that so cheap now everyone’s on the spot. Hence the need for privacy. Back the teams protecting it before @OctantApp's round closes Wednesday
AI just made privacy everyone's problem. paperweight.email's @wslyvh, Jayendra Madaram from @hisoka_io, and @BenDiFrancesco & @huvoliveira from @UmbraCash chat privacy in the age of AI. You can support their work at epoch.octant.app/ until October 21.

Guess who's also going to be able to ship its v2 with support from the current @OctantApp Privacy Round? Here's a sneak peak on what we've been building to improve the OG stealth address protocol on Ethereum.
the wait is almost over v2 is coming tomorrow

Umbra now supports USDG on @ethereum and @arbitrum. Receive @Paxos' Global Dollar at a fresh stealth address. And you can withdraw without holding ETH for gas.

One of the best aspects of @OctantApp's model is the collaborations it helps unlock. Here's to a more private world!
Private payments shouldn’t require both sides to use the same privacy protocol. We’ve been exploring a concept with @UmbraCash: start from Curvy without exposing a clean public link to the original payer, and deliver the payment to a fresh Umbra stealth address on the other side. We’re also looking at the reverse flow: withdrawing from Umbra directly into Curvy’s private pool instead of a publicly known address. Still a concept, not a live integration yet, but exactly the kind of privacy composability we’d like to see more of. We met through @OctantApp Epoch 13 and decided to use the round to explore something concrete together. Explore Octant Epoch 13, epoch.octant.app/rounds/0x57…, and vote for Curvy, Umbra, or any privacy project you believe in.

One of the best things about @OctantApp's Epoch 13 has been finding specific ways privacy projects can compose rather than just campaign next to each other. For example, stealth addresses protect the receiver but what happens after withdrawal is also key. To address that, we started exploring a concept with @0xCurvy where funds received through Umbra can move directly into Curvy’s private pool instead of being withdrawn to a publicly known address. The idea is to extend privacy beyond the first hop and reduce how much any one layer can see about the full payment path. It's not live yet, but we're working on it! Check out the teams building in this Privacy Round and vote for Umbra, Curvy and any project that catches your eye. Deadline is this Wednesday, Oct 21, 8pm ET.

Three is the number. Consider allocating $20 in ETH to vote on @OctantApp's Epoch 13, which curated a cohort of excellent teams building very useful privacy tools. The round closes this Wednesday at 23h59 UTC, 8pm ET, and you can select your favorite projects 👇
Less than 3 days left and only 50.21% of the quadratic funding matching pool is unlocked. Privacy is a key human right. Help fund the teams protecting it in an increasingly dystopian world. Back Umbra and 12 other excellent projects. And split your support to unlock more funds!

We now have flying cars. Can we have private payments by default? Back Umbra v2 and other projects in @OctantApp’s privacy round so we can unlock the 100 ETH matching pool. Round closes Oct 21. And small contributions count the most! Let's build Privacy City together 👇

Thanks @OctantApp, @wslyvh, and @hisoka_io for today's stream. A few of the great takeways: - With AI everyone's a cheap target for a privacy attack. - Privacy is multiplayer, depends on what other people share about you. - And we need to defend our right to leave fewer traces.
