Zapper was designed for DeFi users who wanted to view their on-chain holdings and activity across wallets, networks, and protocols in one place. It brought together token balances, DeFi positions, and NFTs, and let users look up wallet addresses or ENS names to explore holdings and activity. The service also included tools to discover DeFi protocols and opportunities, swap tokens, and bridge assets between networks. Zapper’s website, mobile apps, and API shut down on August 3, 2026, so it is no longer suitable for anyone looking for an active portfolio tracker.
