Umbra v1 remains a workhorse in the privacy ecosystem. The most widely used stealth address system in crypto, with a hundred thousand users, @ScopeLift is committed to maintaining v1, even while we work to ship Umbra v2. Here are some improvements we've made recently 👇

1/6 This is our first deep dive on privacy preserving tech on Ethereum. We present the @umbracash stealth address protocol, enabling private payments on all EVM chains. Senders can generate one-time addresses controlled by recipients, where only sender & recipient know the link.

In the past couple of weeks we: • Made optimizations that reduce scanning times by 50% or more • Cut down on RPC calls made by the client to reduce errors for users with spotty or slow internet • Migrated from MATIC to POL • Improved wallet support & squashed bugs

@ScopeLift Here's the video: youtube.com/watch?v=C1bic_… Shout out to @ekang426 and the BUIDL team for what's surely going to be one of the best conferences of 2026. Sad we aren't able to make it to Seoul for BUIDL Asia this April!

During @buidl_conf's BUIDL Europe 26, @huvoliveira asked a room full of builders if anyone had used stealth addresses. Not a single hand. Well, now the video's out! Check the link below learn about the privacy paradox and the untapped potential of stealth addresses (& Umbra!)

Very cool proof of concept by EF researcher @nero_eth, our co-author on the stealth address ERC standards, demonstrating privacy preserving agentic interactions using stealth addresses. This leverages our SDKs under the hood. Very nice!

AI agents need privacy, and Ethereum can provide it. Here’s a clip of two autonomous agents discovering each other, generating stealth addresses, and interacting privately on Ethereum. More details in the 🧵👇

Umbra wouldn't have been possible without the generous support of various stakeholders, large organizations & individuals alike. We hope to pay it forward and play a significant part in contributing towards making Ethereum cypherpunk again 🫡 /end

We plan to launch v2 this summer. We're looking to develop partnerships that can extend the impact of stealth addresses. If you're interested in using stealth addresses to provide better privacy for your users, please reach out!

*Dusts off the mic* 🎤 Can anyone hear us out there? It's been a while since we last gave an update on the state of Umbra. Let's rectify that 👇
