The BSC (Belt and Beefy Smart Contract) is a very old proxy contract that interacts with Alpaca, Belt, and Beefy. However, due to the age of the contract, it is now believed to be malicious. The BSC is a decentralized application (DApp) that runs on the Ethereum blockchain and is used to securely store and transfer digital assets. It is programmed to interact with the other two protocols, Alpaca and Belt, to facilitate the transfer of funds between users. The BSC also provides an automated system for managing digital assets, such as tokens, coins, and other digital assets. As a result, users can securely store and transfer their digital assets without the need for a third-party intermediary. Despite its age, the BSC is still a useful tool for securely transferring digital assets and is used by many users today.
