The "Swap" tab is where you can trade one token for another. It is a simple swap interface, just select the two tokens you wish to exchange.
The liquidity provided to the exchange comes from Liquidity Providers ("LPs") who stake their tokens in "Pools". In exchange, they get LP (Liquidity Provider) tokens, which can also be staked to earn VOLT tokens in the "farm".
When you make a token swap (trade) on the exchange you will pay a trading fee. A portion of the trading fees is distributed amongst VOLT stakers.
We will also offer a StableSwap integration for users to be able to swap between stablecoins with low to 0% slippage. This mechanism was brought to us by the Curve Finance team. You can read more about how it works here.
