Using MetaMask

What is MetaMask
From the MetaMask website, MetaMask is a crypto wallet and gateway to blockchain apps. It is available as a browser extension and as a mobile app, Metamask equips you with a key vault, secure login, token wallet, and token exchange - everything you need to manage your digital assets. MetaMask was created out of the need of creating more secure and usable Ethereum-based websites. In particular, it handles account management and connecting the user to the blockchain.
You can learn more about MetaMask from the official website metamask.io and from this video​
To use Xend finance, which is a decentralized application (dApp), the Xend finance website needs to be connected to MetaMask, and since MetaMask is also a web browser extension this connection is quite straightforward to accomplish.

Network Details
Binance Smart Chain Mainnet
Testnet - Binance Smart Chain
Binance Smart Chain (BSC) is best described as a blockchain that runs in parallel to the Binance Chain. Because BSC is EVM-compatible, it launched with support for the rich universe of Ethereum tools and DApps. This version of Xend Finance is running on the Binance Smart Chain network because of its interoperability, fast throughput, high security, and its on-chain governance.
