Just built a minimal forum where all posts are stored fully onchain on Optimism. 

No backend, no database – everything lives on the OP chain via smart contracts. 

It’s live here: https://evm-app.vercel.app/ 

Designed to be lightweight and censorship-resistant. 

Wallet login, post creation, and retrieval are all done onchain. 

Looking for feedback or ideas – give it a try!

Note: Please do not use your main wallet.
