FAQ
Swapping WETH — FAQ
How do I swap WETH on Polygon?
Connect a wallet, keep WETH 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 WETH?
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 WETH rate is shown first. Rates move with the market, so the quote refreshes as you type.
Which tokens can I swap for WETH?
The widget opens with POL as the other asset on Polygon. Choose another supported token or network to compare available routes. Availability depends on the token, amount and provider; keeping POL for gas is still necessary.
Is WETH available on other chains?
The catalog contains tokens using the WETH symbol on 11 networks. Matching symbols do not establish equivalent assets: check the contract and issuer on each network. This page selects WETH on Polygon. Quote availability depends on the provider and amount.
Does SwapRoute hold my WETH?
No. SwapRoute is a non-custodial routing interface. You connect your own wallet, review the transaction, and sign directly — your WETH never touches our servers and we never hold your keys.
