Koan

Koan is a decentralized protocol for confidential cross-chain digital asset management, designed to help institutions and developers move assets between blockchain networks without relying on a single trusted intermediary. Its services include confidential asset custody, cross-chain bridging, and shielded integrations between Zcash and EVM-compatible networks. Koan supports assets such as Bitcoin, Zcash, Ethereum, and stablecoins across networks including Ethereum, Avalanche, Polygon, Binance Smart Chain, and Solana.

The protocol uses secure multiparty computation, including FROST, alongside zero-knowledge proofs to protect transaction data and cryptographic keys across distributed nodes. Its bridging process locks assets on an originating chain and issues corresponding wrapped assets on a destination chain, with a path to release the original assets back. Koan also offers developer-oriented integration with existing tools and APIs, on-chain verifiable reserves, and a network of globally distributed validators and MPC nodes. Use cases include confidential treasury management, large trades, settlement, asset audits, multi-chain collateral, and liquidity provision.
