I want to buy an etherium token (the etherisc DIP token). It is available on uniswap etherium network. I don't fully understand how uniswap ans L2s works, so pardon my question.
Can I use the arbitrum, optimism or polygon to buy the token? Or would someone need to "create" the DIP token on the L2 network before? Or is it just that there is no liquidity on the L2?
Obviously I ask to save on gas fees.
