the narrative of meme coin shifting to base though i don't know how these meme coin trend could be shifting blockchain and all the meme coin degen and fans just know that they should look for new meme coin somewhere else that is base, kinda awesome if you think about it.

I mean even before the meme coin was really a thing in base, when most of meme coin still getting deployed in solana, base are already having some good time with all the NFT minting probably due to the fee that is astonishingly low if compared to other chain, I guess thats why.
