Lethe allows anyone to securely and privately transfer, shield, or unshield their Solana, enabling enhanced user security for those who are active on-chain. We've built our protocol on the backs of two amazing protocols, Arcium and LIght Protocol, and we leverage their ZK (Zero-Knowledge) tools to enable trustless on-chain privacy and security.
