 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.

 ### How does interBTC maintain its peg?
 
-The BTC-Parachain ensures that for each minted interBTC: (1) there is an equivalent amount of BTC physically locked on Bitcoin, and (2) there is sufficient DOT collateral locked to economically back minted interBTC in case vaults attempt theft. As such, interBTC is a hybrid peg, with supply determined by both locked BTC and DOT.

 In 2016, the [Polkadot whitepaper](https://polkadot.network/PolkaDotPaper.pdf) identified secure interoperability with Bitcoin as a critical and also challenging feature. In January 2020, with the launch of Polkadot on the horizon, the [Web3 Foundation](https://web3.foundation/in) commissioned [Interlay](https://www.interlay.io/) to design a trustless bridge from Bitcoin to Polkadot based on [XCLAIM](https://www.xclaim.io/) — a carefully designed, open and trustless system that guarantees the security of user’s funds.

 All roles are coordinated through the **Parachain Execution Environment**, which encodes the functionality to issue, transfer and redeem interBTC, and enforce correct behavior of Vaults. Thereby, the Parachain implements a multi-stage collateralization scheme, to protect against exchange rate fluctuations. The Parachain also verifies the correct execution of payments on Bitcoin via BTC-Relay, a Substrate Bitcoin SPV client. To transfer interBTC to other Parachains, an integration with Polkadot’s Cross-Chain Message Passing (XCMP) will be provided.
