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.
