NFT Marketplace

Overview

A marketplace for minting, listing and trading NFTs, built around one non-negotiable: creator royalties are enforced at the contract level, not as an optional field a marketplace can quietly ignore on resale.

The Problem

Creators on existing marketplaces were losing royalty income the moment a piece resold anywhere the royalty wasn't enforced — a courtesy fee a marketplace can switch off whenever it's convenient isn't a real incentive to list there in the first place.

• Several larger marketplaces had already made royalties optional at checkout, and creators had no way to stop a buyer from opting out.
• Minting fees upfront meant creators paid before knowing if a piece would sell at all.
• There was no verification signal to tell a buyer whether a listing was the creator's genuine mint or a copy.

How We Solved It

We built royalty enforcement into the contract itself, so it survives resale on other compatible marketplaces rather than depending on every platform's goodwill. Gasless minting removed the upfront cost barrier for creators, with fees settled at sale time instead, and a verification flow lets buyers trust what they're bidding on.

• Gasless minting for creators, with fees settled at sale time.
• On-chain royalty enforcement that survives resale elsewhere.
• Collection pages, offers, and auction-style listings alongside fixed price.
• A verification flow for creators, so buyers know what's authentic.

Key Decisions

• Royalty enforcement at the contract level, using a standard other compatible marketplaces already honour, rather than a proprietary mechanism only this platform respects.
• Gasless minting funded by the platform up front, recouped from the sale fee — creators never pay to find out a piece doesn't sell.
• Creator verification tied to a one-time identity check, not a recurring subscription fee that would price out smaller creators.

The Result

Creators keep their royalty on every secondary sale, enforced on-chain rather than promised in a terms-of-service page — which became the marketplace's actual pitch to creators deciding where to list.

Verified creators saw meaningfully higher first-week sell-through than unverified listings, and the platform paid out royalties on every tracked resale since launch, including sales that happened on other compatible marketplaces.
