Arcane is a decentralized, non-custodial privacy protocol built natively on Solana. It runs a set of on-chain smart contracts that function as shared mixing pools, allowing users to deposit assets from one wallet and withdraw those assets to a separate, unlinked wallet. Because every deposit flows into the same pool and every withdrawal is verified through a zero-knowledge proof (a cryptographic method that confirms a statement is true without revealing the underlying data), an outside observer cannot determine which deposit corresponds to which withdrawal. The result is on-chain privacy without leaving Solana, bridging to a privacy chain, or trusting a custodian.
