For every swap on the exchange on every chain, 0.05% of the swap fees are distributed as WWT proportional to your share of the WWTBar. When your WWT is staked into the WWTBar, you recieve xWWT in return for voting rights and a fully composable token that can interact with other protocols. Your xWWT is continuously compounding, when you unstake you will receive all the originally deposited WWT and any additional from fees.
