What it costs
On this quote, $1,008 of ETH became $1,005 of ETH on zkSync: about $3.29, or 0.33%, for everything taken out on the way. That includes the 0.15% Shieldz fee, the protocol's own fees and the gas to deliver to you. The network fee your wallet pays to send is extra.
MetaMask's built-in swap charges 0.875% and Phantom's 0.85% before any of that. Compare on your own amount.
Mainnet gas is paid in ETH and gets expensive when the network is busy. For smaller swaps, a layer 2 such as Base or Arbitrum usually costs less.
