The Interlay team is building a customized Substrate environment for interBTC, optimized to verify Bitcoin payments. The BTC Parachain includes a Bitcoin cross-chain SPV client (BTC-Relay), integrations with secure price oracles and XCMP, as well as support for hardware wallets. In addition, Interlay is also building client software for Vaults, Relayers (who make sure BTC-Relay is up to date), as well as an easy-to-use web interface.
Interlay has previously released a detailed technical specification and a working PoC implementation. After the successful pilot project, Interlay won a second Web3 Foundation grant to complete the BTC Parachain - the core milestones of this project were completed in March 2021.
