Ether, or ETH, is the native token of the Ethereum blockchain. Wrapped ETH, or WETH, refers to an ERC-20 compatible version of ether. ERC-20 is a technical standard developed after the release of ETH that allow tokens created on the Ethereum blockchain, such as ZRX, to interact with each other.
In order for ETH to be exchanged with other Ethereum-based tokens, it needs to be wrapped into WETH. Wrapping ETH does not affect its value, 1 ETH = 1 WETH.
WETH is also one of the tokens that allows Matcha users to utilize our Gasless Trading option. Check out our Help Page on Gasless Trading here to learn more.
