Computation is broken. Whoever processes data must access it, exposing it to attacks, exploits, and risky trust assumptions. Traditional cryptography protects data at rest and in transit, but data usually has to be exposed during computation. That makes sensitive workloads difficult to build on transparent systems such as public blockchains. Arcium provides confidential computation through the blockchain. It uses Multi-Party Computation (MPC) so applications can compute over confidential data while keeping inputs hidden from any single node.

Key benefits

Arcium gives applications a way to add confidentiality without leaving the Solana ecosystem.
  • Confidential inputs and outputs: Process sensitive data without exposing it to any single node.
  • Onchain coordination: Use Solana for orchestration, finalization, and application integration.
  • Developer tooling: Build confidential instructions with Arcis, Anchor-compatible Solana programs, and the TypeScript client.
Use cases include confidential DeFi, private AI inference, sealed-bid auctions, hidden-information games, and other applications where data must remain confidential during computation.
