Introduction to MetaMask and BNB Chain
MetaMask is a leading browser-based cryptocurrency wallet that enables users to interact with blockchain networks like Ethereum, BNB Chain (formerly Binance Smart Chain), and Polygon. It serves as a gateway to decentralized applications (DApps) and manages private keys securely.
BNB Chain, initially launched as Binance Smart Chain (BSC), is a high-performance blockchain developed by Binance. It operates on a Proof-of-Staked Authority (PoSA) consensus mechanism, offering faster and cheaper transactions compared to Ethereum. The network uses BNB as its native token for gas fees and staking.
