Anyone can add liquidity across the full price range of a token pair on Uniswap v2, v3, and v4.
Adding liquidity for the full range means supplying liquidity across all possible price levels for a token pair, from zero to infinity.
It is important to understand that token prices may not reach all these price levels. Wide ranges can earn lower fees compared to concentrated positions in narrower price ranges where trading is more likely to occur.
