Metamask has an option to Swap tokens within the app itself and normally you pay a small fee for this operation. In the latest update, it got the possibility to wrap and unwrap tokens with no fees.
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. Via I know what ETH is but what is WETH?
And now, if you have an ENS domain that resolves to your Metamask address, your Metamask account will be named with your .eth address as well.
