Launched by ConsenSys Systems in 2016, Metamask stands as one of the earliest Ethereum-based crypto wallets. It now accommodates over 450,000 assets across Ethereum, BNB Chain (formerly Binance Smart Chain), Avalanche, Polygon, and various test networks. Its early debut and decentralized approach—without storing user data—have made it a favorite among crypto and NFT enthusiasts. Metamask saw significant growth during the rise of NFT platforms in 2017 and the record-breaking global NFT sales of 2021. Looking ahead, Metamask is poised for an exciting future as it prepares to navigate the emerging metaverse landscape.
