Wrapped ETH, or WETH, is a token that represents Ether 1:1 and conforms to the ERC20 token standard. ETH and WETH are always exchanged at a 1:1 ratio, no need to worry about any price fluctuations.
ETH does not adhere to ERC20 standards and cannot be traded directly in a decentralized environment. WETH is an ERC20 token that stays in your wallet throughout trading.
To unwrap your ETH manually, have a look at these options:
Use 1inch.exchange: https://1inch.exchange/#/WETH/ETH
Use the WRAP/UNWRAP functionality on Radar Relay: https://app.radarrelay.com/ZRX/WETH
We are prioritizing automatic unwrapping within Zerion as an upcoming feature update! Stay tuned π
