- Enter an amount. Relay and NEAR Intents quote it at the same moment, with the amount you receive and the time it takes.
- Paste the Base address you want to receive at, or connect a Base wallet and pick one.
- Review the minimum you receive and the fees, then send from Ledger, Trezor, Keystone and MetaMask. Shieldz tracks the swap until it lands.
What it costs
On this quote, $1,006 of ETH became $1,004 of ETH on Base: about $2.38, or 0.24%, 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.
