No. Like many other Web3 applications, Zapper does not custody or control your assets. Our Dashboard draws from on-chain data after you connect your wallet to visualize a snapshot of your DeFi portfolio. Our Zaps help to add liquidity, withdraw liquidity, or rebalance liquidity between two platforms. All of the functionalities mentioned above do not have custody of your assets. Your cryptocurrencies exists with the application that holds your private key, such as MetaMask or Ledger wallet.
