We envision a future where blockchains seamlessly connect and interact: anyone can use any digital asset on any blockchain, trustless and without limitations. We work with Bitcoin, Ethereum, Polkadot, Cosmos and others to expand interoperability, capital efficiency and openness.

Our flagship product is interBTC - Bitcoin on any blockchain. A 1:1 Bitcoin-backed asset, fully collateralized, interoperable, and censorship-resistant, realizing the true free nature of BTC and decentralized finance.

At Interlay, we live decentralization and transparency. We’re 100% remote and all our code is open source. We’re not anonymous - we stand by our product. Our projects are community-owned and backed by top-tier scientific papers. Founded by ex-Imperial College PhDs, we collaborate with leading research labs and tech companies around the world.
