OnChat – Fully permissionless, on-chain paid group chat protocol

Summary: OnChat is a 1-click paid group chat launcher on Base that enables embedding monetized chat channels directly into apps or websites. It operates fully on-chain without any backend servers, using smart contracts and RPC calls to Base for message handling and payments.

What it does

OnChat allows users to create paid group chats with embedded plugins that handle messages and payments on-chain via Base. Every message incurs a small ETH fee, which is earned by channel owners.

Who it's for

It targets web3 product builders seeking to add monetized community chat features without managing servers or centralized infrastructure.

Why it matters

OnChat eliminates backend dependencies by storing chat data on-chain, ensuring persistence and permissionless access even if the service is no longer maintained.
