Auran

Auran will build the first cross-chain Bitcoin protocol based on its own custom L1 framework, which will utilize the Cosmos SDK, Tendermint, and a decentralized TSS network. This protocol will serve as a liquidity layer, connecting the emerging Bitcoin Layer 2 (L2) ecosystem with the Bitcoin blockchain. It will enable users to conduct local exchanges and support major meta-protocols such as Runes, BRC20, and Ordinals. In addition, the protocol integrates a messaging system that facilitates cross-chain smart contract interactions within the Bitcoin ecosystem.
