Umbra, a privacy-focused wallet built on Arcium's encrypted execution engine, has officially launched on the Solana blockchain. The release marks a significant expansion of access to encrypted onchain finance, moving beyond the limited user onboarding of its initial private mainnet deployment following Arcium's Mainnet Alpha debut in February 2026.
The wallet enables users to conduct fully private transfers, where the sender, recipient, and transaction amount are concealed. It also supports encrypted swaps that hide trade size and execution intent. "Every move is public, permanent, and traceable by anyone. Umbra is the first system that changes that," said the wallet's co-founder known as "Kru."
Unlike traditional obfuscation or zero-knowledge proof systems, Umbra leverages Arcium's trustless encrypted execution infrastructure. This technology processes transactions without exposing underlying data at any stage of computation, a structural shift for privacy on public blockchains.
Alongside privacy features, Umbra integrates a suite of regulatory compliance tools, including viewing keys, risk filters, and geographic blocking, aiming to balance confidentiality with regulatory requirements for traders, businesses, and institutions.
The project has also released a Software Development Kit (SDK), a zero-knowledge-based anonymity architecture that extends Arcium's infrastructure to developers building applications on Solana. The team announced that several project integrations are expected in the coming weeks.
Demand for the solution is underscored by substantial early backing. In October 2025, Umbra secured over $150 million in commitments from more than 10,000 participants through MetaDAO, one of the largest capital raises ever recorded on that platform. Arcium CEO Yannik Schrade noted, "the conversation around privacy has never been more intense, and the technology is finally ready."
