Zapper does not have any custody or control over your assets. Once you connect your wallet to Zapper, our homepage populates the information you see about your assets by pulling public-facing on-chain data associated with your wallet address.
No one who works at Zapper has access to any information that would give them control over your assets, and neither does the platform itself. This is because your assets are secured within the application that holds your private key, such as your MetaMask or Ledger wallet.
It is important to note that some wallet providers are custodial, meaning that they have a record of the private key associated with the wallet that holds your assets. The Coinbase Wallet is an example of a custodial wallet. It is important to note that Zapper does not have control over your assets, even if you are using a custodial wallet provider.
