Resale Settlement Layer

Link resale to the receipt.
Pay the brand its royalty.

Run a resale marketplace where each luxury item's authenticity is verified against its original purchase record, with the brand receiving a resale royalty. Provenance Notary, DID and VC Ledger, and ERC-721 NFT link each resold item to its origin and automatically pay the brand a share of every verified secondary sale.

The Foundation

The Execution Mechanics

Turn an untraceable secondary market into verified resales that protect buyers and pay brands a stake.

01.

Original Purchase Linkage

Anchor resale to origin. The Provenance Notary links each listed item to its original purchase record, so a resale buyer verifies the item is the exact one first sold, not a counterfeit copy.

02.

Automatic Brand Royalty

Pay the maker on every resale. The contract routes a set royalty to the brand on each verified secondary sale, giving brands a stake in a market they were previously locked out of.

03.

Seller Credential Proof

Confirm the seller can sell it. The DID and VC Ledger proves the seller holds the item's ownership credential, blocking listings from those who never owned the good.

04.

Counterfeit Screening

Keep fakes out of circulation. An item with no matching original purchase record fails listing, so counterfeits cannot enter the resale marketplace in the first place.

05.

Ownership Transfer

Move the twin with the sale. The ERC-721 NFT transfers to the new owner atomically with payment, so the provenance record stays accurate through every resale.

06.

Brand Market Visibility

Give brands a window on the secondary market. Verified resale data shows brands how their products trade after first sale, informing pricing and product decisions.

The Resale Lifecycle

Follow a resold luxury item from listing through authenticity verification to a settled sale with brand royalty.

Smart Contract Anatomy

Cerulea decomposes resale settlement into modular contracts. Each layer verifies the listing, proves the seller, splits the royalty, and transfers ownership without a counterfeit slipping in or a brand losing its share.

Applicability Across the Spectrum

Verified resale with brand royalties is a horizontal capability. Here is how different actors in the secondary market put the shared ledger to work.

Resale Marketplaces

Keep counterfeits out and buyers protected. Platforms verify each listing against its original purchase, so shoppers trade with confidence in a market cleared of fakes.

Network & Execution Architecture

Whether you are bridging brand and marketplace systems or routing native wallet-based resales, Cerulea settles every secondary sale against one shared provenance record.

Track A: Brand & Marketplace Bridging

For brands and platforms on legacy commerce systems. Original purchase records and listings are translated into verified on-chain resales through the API gateway automatically.

Technical Methodology

The legacy timeline reflects marketplace engineering benchmarks. Linking resales to original purchases, verifying ownership credentials, and building automatic royalty settlement for an average platform takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your verification and royalty rules into pre-audited WebAssembly binaries and provisions the resale ledger instantly.
