Bitcoin Bridge: contract-based wrapping and liquidity of BTC as in Interlay

We are adapting Interlay’s BTC<>DOT bridge to support finance products on wrapped Bitcoin. Our long-term value proposition is the utility of ETH<>ONE<>BTC hub as liquidity infrastructure. Keep’s tBTC, Interlay’s PolkaBTC and Thorchain are only reaching basic production but highly valued. Our bridge can then easily generalize to many Bitcoin-based assets such as Tether’s USDT, Litecoin and Bitcoin Cash. Along with our Ethereum bridge, we can enable a truly decentralized exchange across chains with BTC derivatives, USDT stablecoins and ERC20 assets.
