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.Grab some free testnet tokens here:
