Screen Sync is a peer-to-peer advertising marketplace built on Solana, connecting advertisers directly with the people and businesses that own digital spaces and audiences. The platform treats attention as bookable inventory, allowing users to list websites, digital signage, venue screens, and in-game placements, including banners, sponsorships, takeovers, and stream or loading-screen ads.

Owners set their prices, availability, and content rules, while advertisers can browse placements, review pricing and audience context, and book directly without broker chains. Screen Sync uses on-chain escrow to hold funds and release payment when a placement runs. Bookings, payments, and proof-of-display are recorded on-chain so both parties can verify delivery. The service emphasizes transparent terms, a visible flat protocol fee, and direct payouts rather than layered intermediary charges.

Screen Sync also promotes contextual advertising and data ownership: placements are based on where an ad appears, rather than surveillance-based audience tracking. By using Solana for settlement, the marketplace aims to support frequent, low-cost transactions and quicker payouts.
