Swapping ETH — FAQ
How do I swap ETH on Base?
Connect a wallet, keep ETH as the token you want, enter an amount, and review the best route. SwapRoute compares live quotes from 0x and Relay and shows route details and the minimum received before you sign — no account needed.
What's the best rate to swap ETH?
SwapRoute doesn't rely on a single venue. It queries every capable provider at once and ranks routes by the net amount you'd actually receive, so the best available ETH rate is shown first. Rates move with the market, so the quote refreshes as you type.
Which tokens can I swap for ETH?
The widget opens with USDC as the other asset on Base. Choose another supported token or network to compare available routes. Availability depends on the token, amount and provider; keeping ETH for gas is still necessary.
Is ETH available on other chains?
The catalog contains tokens using the ETH symbol on 8 networks. Matching symbols do not establish equivalent assets: check the contract and issuer on each network. This page selects ETH on Base. Quote availability depends on the provider and amount.
Does SwapRoute hold my ETH?
No. SwapRoute is a non-custodial routing interface. You connect your own wallet, review the transaction, and sign directly — your ETH never touches our servers and we never hold your keys.
