About the WETH to ETH swap

WETH and ETH. WETH is ETH wrapped as an ERC20 token so that DeFi apps can handle it like any other token. Unwrapping WETH gives you native ETH back at a 1:1 rate.
Where your ETH can land. Native ETH on Ethereum, or on Base, Arbitrum One or Robinhood in one transaction from Ethereum.
What you need. WETH on Ethereum in a wallet such as MetaMask, plus a little ETH for gas. The WETH contract on Ethereum is 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2.
Cost. On 6 October 2026, 0.4 WETH turned into exactly 0.4 ETH on Ethereum, with only $0.62 of gas, and into about 0.399 ETH on Base, Arbitrum One or Robinhood with fees of $1.97–2.79.

Swap WETH to ETH in Symbiosis PRO mode: 0.4 WETH (Ethereum) to 0.4 ETH (Ethereum)

How to swap WETH to ETH

Example quote from 6 October 2026: swapping 0.4 WETH (~$1,080) on Ethereum in the Symbiosis app returns about 0.4 ETH on Ethereum, delivered in under a minute. Behind the swap, Symbiosis checks several routes and chooses the one with the best price, fee and speed. Here is the flow:

Open the swap. Go to the Symbiosis app and connect an Ethereum wallet such as MetaMask. There is no sign-up and no KYC.
Pick the token you send. Choose WETH on Ethereum in the From field.
Choose ETH on Ethereum. Set ETH as the token to receive and Ethereum as the destination network. Enter the amount: 0.4 WETH (~$1,080).
Check the quote. Before you sign, the app shows how much ETH you get, the fee, price impact and time. In this example: about 0.4 ETH, no route fee — only gas, with 2% slippage tolerance.
Sign and receive. Confirm the transaction in your wallet; ETH lands in your wallet on Ethereum.

Sample WETH to ETH quotes

Symbiosis quotes for 0.4 WETH to ETH on 4 networks, taken in the Symbiosis app on 6 October 2026. Receive is the amount of ETH that lands in your wallet. Fee is the full cost in USD as shown in the Symbiosis app — the value you send minus the value you receive, never less than the route fee — plus source-network gas. Time is the median delivery time from Ethereum to each network over the 90 days to 29 September 2026; for a swap inside Ethereum, the app estimate.
