Zerion is a non-custodial wallet designed to give users full visibility and control over their crypto activity across multiple blockchains. Founded in 2016, Zerion started as a DeFi portfolio tracker and has since evolved into a complete wallet solution that supports sending, receiving, swapping, bridging, and tracking assets across more than 51+ networks, including Ethereum, Arbitrum, Optimism, Base, Solana, Polygon, and more. Zerion Wallet is available as a mobile app and browser extension. It combines wallet functionality with portfolio analytics, allowing users to manage tokens and DeFi positions in one interface. The wallet automatically tracks holdings and transaction history by parsing multichain data, removing the need for manual input or multiple wallets per network. The transaction history feature gives users a detailed view of trades, transfers, airdrops, and contract interactions across all supported chains. Zerion also offers the best rates for token swaps, integrating leading aggregators like 0x, 1inch, and Jupiter to provide competitive rates for token swaps and bridges. For users who track other wallets or onchain activity, Zerion enables “following” addresses to monitor transactions in real time. This feature is popular with traders, researchers, and analysts who want to stay updated on wallet movements across the ecosystem. Zerion is open-source and privacy-preserving—no KYC or email is required, and no personal data is collected. It is widely used by crypto-native users, airdrop hunters, investors, and builders who need a multichain, real-time view of their assets and onchain activity. Zerion is fully remote and operates globally. Its mission is to make self-custody simple, secure, and powerful, especially as crypto expands beyond Ethereum into a multichain future.
