▸ Chain-agnostic: Live on Solana, expanding to EVM next.
▸ Fast: Encrypted computation runs at web speed.
▸ Secure: Uses dishonest-majority MPC with cheater detection.

► Wrap Up
Arcium builds the privacy layer that connects blockchains together.
Over a dozen applications are already live on testnet, with more joining through the Colosseum Hackathon. The C-SPL (Confidential SPL Standard) is being tested to make privacy native across the Solana ecosystem.
With mainnet approaching, Arcium moves from optional privacy to core infrastructure for secure computation on
@solana and beyond.
