From the Marketplace, you can swap tokens at the current exchange rates. You can also become a liquidity provider by adding liquidity to any token pools you’d like. These will earn you fees any time anyone trades those tokens. Additionally, the LP tokens for certain incentivized token pairings can also earn RUBY rewards when staked in the Farms.
