Carver is a cross-chain DeFi platform that aims to bring liquidity and lending services to major cryptocurrencies outside of the Ethereum ecosystem. It offers a stablecoin called Usdx, which is pegged to the US dollar, and allows users to customize collateralization ratios for loans. Carver currently supports Binance Coin and plans to add Bitcoin and XRP in the future. Users can also earn high yield income by becoming a Usdx minter. Carver is built using the Cosmos SDK, which allows for interoperability with other blockchains. Over-collateralization is used to ensure the stability of loans on Carver.
