Staking : staking is not traditional staking. Betting on posts is relevant's 'staking' . So you can earn passive tokens by using your pool to bet on relevant posts with no risk of losing what you have . Swap : on uniswap connect a wallet and use eth to get relevant. Use the arrow to convert rel to eth. You are probably off watching a YouTube video on how to swap on uniswap. It's hard to explain on here but it's the same as any other token.
