There will be many more meme coin created into the TON blockchain spaces once $DOGS turns out to be a massive success but the fact that $DOGS isn't just random meme coin but instead tries to support charity is commendable.
but surprisingly right now most of the project that made up the entire ecosystem of TON are still projects with product and games. so far I haven't seen meme coin hype in TON, and there are limited amount of meme coin that got large market cap. the only one that has interested me is probably Resitance Dog meme coin but the market cap isn't that impressive and the growth doesn't seem to be great.

I think there's still a long way to go for TON blockchain to have meme coin hype as big as its competition (solana, base and ethereum).
