MetaMask, an Ethereum-based cryptocurrency wallet, has registered five million active users, according to its creator, blockchain software firm ConsenSys.

ConsenSys said MetaMask has grown five times in the past six months, thanks to the increasing use of decentralized finance (DeFi) and non-fungible token (NFT) applications. In October 2020, MetaMask had over 1 million cumulative MAUs.

A growing number of users are utilizing the MetaMask Swaps feature, said ConsenSys. The feature, launched last October, allows users to swap tokens directly from their wallets across decentralized exchanges, aggregators, and market makers.

Behind swaps, accessing NFTs is the second most popular use case for MetaMask, said ConsenSys. 

MetaMask was launched in 2016, and up until 2019, it had only been available as a desktop browser extension. MetaMask began releasing mobile apps for closed beta testing in 2019, followed by their official public release for both or iOS and Android in September 2020.

MetaMask also cites increased adoption in developing countries such as India, Indonesia, Nigeria, and Vietnam.
