chadad

chadad is an on-chain sponsored-banner protocol that lets advertisers fund WETH campaigns and rewards viewers for verified banner visibility. A source-reviewed Chrome extension renders eligible campaigns, submits replay-protected device-signed reports, and lets viewers claim cumulative rewards on-chain. The current prototype runs on Robinhood Chain testnet. During the buildathon, the protocol and settlement flow will be ported to Arbitrum Sepolia with fresh contract deployments, updated chain support, and a working end-to-end demo. Pre-existing work and all buildathon changes will be documented separately in version control.
