ETHB Lend (ETHB) is a cross-chain revenue optimizer supported by Filcoin. It is currently located on Ethereum and will cross-chain to Binance Smart Chain in the future. ETHB Lend provides users with a simple but mature user interface that removes the complexity of the original DeFi lending market. The essential function of ETHB Lend is to use intelligent algorithms to automatically calculate risk factors, and allocate assets through the best matching agreement to optimize returns. At the same time, ETHB's decentralized oracle machine provides a credible data source for smart contracts through different technologies and consensus mechanisms.
