The open-source XCLAIM framework allows users to move assets across public/permissionless blockchains such as Bitcoin and Ethereum in a trustless manner. Enterprises, on the other hand, can utulize XCLAIM to execute settlements across different permissioned ledgers, choosing from a palette of possible trust models based on use case and required security.

To fully exploit the benefits of interoperability, Interlay is also building a trustless and non-custodial trading platform for cross-chain derivative trading (e.g. BTC/ETH, BTC/DAI and BTC/DOT).

Trustless BTC-Polkadot Bridge

We are bringing Bitcoin to the Polkadot ecosystem. XCLAIM, the framework underlying the BTC-Parachain, is a carefully designed, open and trustless system that leverages a dynamic set of collateralized intermediaries. Intermediaries are obligated to prove correct transaction execution on Bitcoin, which ensures that users face no financial damage.

Non-Custodial Bitcoin Options

XOpts is the first trustless and non-custodial platform for buying, selling and trading Bitcoin options. Currently built on Ethereum, XOpts enables users to buy and sell Bitcoin options using DAI, or any other stablecoin, as insurance collateral. The option contracts can be traded on decentralized exchanges like Uniswap. Settlement occurs on Bitcoin and is enforced via SPV proofs.
