Tidechain is a substrate-based blockchain designed for swapping between tokens from different blockchains without a central intermediary. It includes a decentralized Quorum, Oracle and secrets-management protocol and has a public on-chain registry of "swap intentions" that allows users to broadcast their desired trade to the world. The chain confirms the exchange according to the wishes of the users on either side of the trade. Tidechain is the backbone of the TIDEFI ecosystem and is purpose-built to enable swapping and control over tokens. Governance of Tidechain is token-based using the chain's native TIDEFI token.
