To place it basically, zksnarks is a proving program, and "zero-knowledge" signifies the verifier gains no understanding about the transaction’s sender, recipient or amounts, providing customers comprehensive privacy and anonymity. If they’ve applied MetaMask or any other common wallet it will be transparently familiar.
