Umbra has officially opened its privacy wallet to the public on Solana, marking a major step in private onchain transactions. The wallet uses Arcium’s encrypted execution engine, allowing fully shielded transfers between private addresses and encrypted token accounts. This allows users to send assets, perform swaps and communicate with Solana without revealing transaction data.
The launch expands access beyond Umbra’s initially phased mainnet rollout following Arcium’s Mainnet Alpha debut in February. Previously, only a limited number of participants could experience Umbra’s shielded financial layer. Now traders, institutions and companies can make private transfers without revealing sensitive information to the public blockchain.
Privacy-oriented transactions
Umbra’s wallet allows users to hide the sender, recipient and transaction amount, providing complete confidentiality. Token swaps also remain private and hide the size and intent of the trade. Additionally, the wallet integrates compliance tools including key viewing, risk screening, and geo-blocking. These measures guarantee privacy while complying with legal standards.
In addition to privacy, the wallet emphasizes usability. It focuses every day userson Solana who are looking for a practical, secure and compliant privacy solution. This approach addresses long-standing blockchain limitations, where transaction data is typically publicly visible and traceable.
Encrypted financial infrastructure
The wallet relies on the encrypted implementation of Arcium, allowing computations over encrypted data. Consequently, no party has access to transaction data during processing. This method differs from traditional privacy approaches that rely on obfuscation, intermediaries, or zero-knowledge systems, which often struggle with multi-party transactions.
Umbra has also released an SDK, which extends Arcium’s privacy infrastructure to developers. This zero-knowledge stack allows new applications to be built on Solana with native privacy. Several projects are expected to integrate this technology in the coming weeks, enhancing Solana’s privacy ecosystem.
“We are experiencing a defining moment for privacy,” said Yannik Schrade, CEO of Arcium. “The conversation has never been louder and the technology is finally ready. Umbra is the first proof of what becomes possible when you build a financial infrastructure powered by encrypted computing power.”
Early adoption and financing
The public launch of Umbra follows high demand for privacy-focused solutions. The project increased more than $150 million through MetaDAO by October 2025, with more than 10,000 participants. This significant support highlights the growing interest in encrypted financial infrastructure.
Now that the wallet is public, Umbra wants to make privacy a default on Solana. By combining usability, compliance and encrypted execution, the platform provides a comprehensive solution for secure and private digital finance.
