Answer 2: The demo you are referring to was a decentralized finance (DeFi) project that was created during Binance's hackathon event. This project was designed to provide users with the ability to interact with multiple blockchains and use their tokens and smart contracts to create a cross-chain, multi-asset platform. This platform was designed to enable users to interact with different blockchains, use their tokens, and create a range of DeFi applications, such as automated lending, borrowing, and trading. The project was also designed to provide users with the ability to access a range of DeFi applications without having to worry about the complexities of dealing with multiple blockchains. This project was a great example of how DeFi can be used to create a wide range of applications and services that can be used by users across different blockchains.
