How the marketplace works
List your idea
Register your proof, then list it on the marketplace — for sale, license, partnership, or co-founder. 5 credits for 3 months.
Buyers discover
Creators, investors and collaborators browse by category and intent. Every listing is backed by a verified Prooflayer proof.
Facilitate your deal
Agree terms directly with the other party, off-platform. We stay out of the deal — no fees, no involvement, full control is yours.
Proof your deal
Once agreed, register your deal documents, contracts, or agreements as a new proof — creating a permanent timestamped record.
A taste of what's coming. All listings will be proof-verified at launch.
