At Interlay, we envision a future where permissioned and permissionless blockchains, regardless of design and purpose, can seamlessly connect and interact. From trustless loans to decentralized derivatives & exchanges, from off-chain payment protocols to application-specific ledgers: anyone should use any digital currency on any blockchain platform.

Trustless BTC-Polkadot Bridge

Interlay is building the official, trustless Bitcoin-Polkadot bridge, in collaboration with Parity Technologies and the Web3 Foundation -- based on top-tier academic research. As the main BTC gateway, PolkaBTC will help bootstrap Polkadot’s emerging DeFi ecosystem.

Open-source, funded by a Web3 Foundation grant

Zero-Trust BTC Options & DEX

XOpts is the first trustless and non-custodial platform for cross-chain BTC options. XOpts also functions as a decentralized exchange for BTC, enabling cross-chain trading against stablecoins and DeFi tokens -- without relying on price oracles or wrapped BTC.
