Our take
In recent years, the Web3 space has become more disparate with the number of decentralized applications having increased, making it harder for users to track their footprints across chains, NFT collections, and DeFi protocols.
San Francisco-based Zerion is a smart Web3 wallet and investing tool that enables mobile users to manage their DeFi and NFT portfolios, offering a single place to manage it all whilst enabling users to trade their assets at the best rates. Essentially, Zerion is catering to the new, modern challenges faced by users during their Web3 experience.
The company, founded in 2016, was named one of the most promising startups of 2022 and now serves half a million active wallets across over 150 countries. Funding raised has also gone towards continuing the company's impressive growth, as well as further innovating its product.
