Arcium has launched its Mainnet Alpha on Solana, introducing encrypted execution as a native infrastructure layer and marking a significant step toward privacy-preserving finance and AI on public blockchains.
Arcium CEO Yannik Schrade said the project reframes privacy as a core design primitive rather than a niche feature, introducing a general-purpose encrypted execution environment that expands what is possible for internet-native financial systems.
The first application to deploy on Mainnet Alpha is Umbra, which brings a shielded finance layer to Solana. Umbra supports encrypted transfers and private swaps and has launched with controlled access, onboarding 100 users per week under a $500 deposit limit. Broader access is expected in February following additional stress testing.
Developer activity around Arcium has increased since its testnet debut in May 2025, with projects such as Melee, Vanish, and Anonmesh building integrations. The roadmap also includes Confidential SPL, which aims to enable confidential tokens directly on Solana.
