To provide liquidity for the $MUTE / $ETH Uniswap pair, you'll need to fund both sides of the exchange. This means you'll need to deposit equal values of both $ETH and $MUTE. For example, if the current price of $MUTE is .001 $ETH, then for every 1000 $MUTE you want to stake you'll also need to deposit 1 $ETH.
