Umbra is now open to the public - powered by Arcium

We have been building toward this moment for a long time.

Today, Umbra is fully open to the public, a private wallet powered by the first shielded pool on Solana. Every Solana user now has access to genuinely private sending, swaps, yield, and compliance stack built for the real world and much more. All of this, neatly packaged into a wallet built for everyday use.

Privacy on-chain has been complex, hard to access, lacked composability, or faked entirely. Many solutions just obscure data or mislead users through fancy messaging, while in reality its creative obfuscation, not privacy.

Umbra is different because what it’s built on is different.

Arcium’s encrypted execution engine provides the infrastructure to execute computations over fully encrypted data. It’s an entirely new form of computing.

Send and swap assets on Solana with full transactional privacy. Sender, recipient, and amount are shielded. Now available to every Solana user for the first time, without compromise.

Try it here.

Umbra’s SDK is now open to developers. Any team building on Solana can integrate private transfers, encrypted swaps, and anonymity primitives directly into their applications. Umbra’s SDK extends Arcium’s encrypted compute. Umbra enables anonymity while Arcium brings confidentiality and arbitrary compute. Together, they cover the full privacy spectrum, unlocking an entirely new design space for applications.

Integrate now.

One of the most persistent myths in crypto is that privacy and compliance pull in opposite directions. Umbra breaks out of this paradox.

Three compliance features go live alongside the product:

Granular Viewing Keys — Share precise transaction data by date range or individual transaction for targeted audits. Users control exactly what is disclosed and to whom, without exposing their full financial history.

Range Risk Screening — Multi-hop analysis across 99+ chains automatically identifies and blocks OFAC-sanctioned and blacklisted wallets before a transaction is initiated. Compliance happens at the infrastructure level, not as an afterthought.

Geo-Blocking — Instant jurisdictional access controls ensure Umbra operates within legal frameworks across global markets, automatically.

Institutions, regulators, and everyday users can all trust this product. That combination has not existed on a public blockchain before today.

Umbra’s public mainnet is the first proof of what Arcium makes possible.

Since our Mainnet Alpha launch in February, the ecosystem building on Arcium has continued to grow — with Melee, Bench, Crafts, and others building toward their own launches. The Umbra SDK extends that surface area further, giving every developer on Solana access to the same privacy primitives that power Umbra.

Combined with Arcium’s generalized encrypted execution engine, developers have access to everything they need for performant, powerful privacy primitives for any new or existing application.

If you are building something that requires privacy or confidentiality in DeFi, AI, or beyond we want to hear from you.
