Platform Features
Everything a modern NFT platform needs
Full-stack — contracts, frontend, and data indexing — all in one engagement.
Mint Engine
Public mint, allowlist (Merkle tree proof), Dutch auction, and reveal mechanics. Configurable from admin dashboard — no redeployment for price or supply changes.
On-Chain Royalties (EIP-2981)
Royalty enforcement built into the contract. Compatible with OpenSea, Blur, and every EIP-2981-respecting platform — creator earns on every secondary sale, automatically.
Auction & Bidding
English auctions, reserve prices, Buy Now, and open offer systems. Real-time bid updates and automatic settlement triggered by smart contract — no manual intervention.
Creator Dashboard
Collection management, analytics, withdrawal tools, and bulk metadata upload. Creators manage their own collections without touching code or contacting support.
Marketplace Analytics
Floor price, volume, unique holders, sale history, and rarity rankings — served from The Graph subgraph for sub-second queries. No manual refresh, no stale data.
Anti-Bot Protection
CAPTCHA integration, wallet age limits, max-per-wallet caps, and Merkle tree allowlist verification — keeps mints fair and bots out of your launch day.
Why third-party platforms cost you more
OpenSea and its competitors aren't neutral infrastructure. They're competitors for your collector relationships.
OpenSea Takes 2.5% of Every Sale
A collection doing $1M in volume sends $25,000 to OpenSea. Over $10M, that's $250,000 — gone. These aren't payment processing fees you can't avoid. They're a platform tax for using someone else's infrastructure. Your community, your collection, someone else's revenue.
Our approach
Your own marketplace at your domain — 100% of platform fees go to your treasury. Payment processing (card, crypto) costs exist, but no percentage cut to a third-party platform. Own your revenue.
Platform Types
Build the right marketplace model
Not sure which model fits? Free scoping call to figure it out.
Single-Creator Platform
Dedicated marketplace for one artist, brand, or IP — with custom domain, full brand identity, exclusive collection management, and 100% fee routing to you.
Multi-Creator Marketplace
Open platform where multiple creators list, sell, and manage collections. Creator application flow, curation controls, featured placement, and split fee routing.
Gaming Asset Exchange
In-game items, characters, and land parcels traded peer-to-peer. Integrated with game authentication, real-time item attributes, and in-game wallet connection.
Real World Asset (RWA) NFTs
Tokenized physical assets — art, real estate, collectibles — with legal wrapper documentation, custody verification, and fractional ownership support.
Design → Contract → Launch
A 5-phase process that ships a fully branded, audited NFT marketplace — from spec to launch day.
Collection & Marketplace Design
Token standard selection (ERC-721 vs ERC-1155), minting mechanics, marketplace rules, royalty model, and creator tools all scoped before any development. Deliverables: contract spec, marketplace wireframes, and IPFS metadata structure.
Smart Contract Development
ERC-721/1155 contracts with OpenZeppelin patterns, marketplace contracts with escrow and settlement logic, EIP-2981 royalty enforcement, and operator filter registry. Hardhat test suite with 95%+ coverage targeting auction edge cases and reentrancy vectors.
Marketplace Frontend & Indexing
Next.js marketplace UI with gallery views, mint pages, auction flows, and creator dashboard. The Graph subgraph for real-time collection analytics. RainbowKit wallet connection — MetaMask, WalletConnect, Coinbase, Ledger.
Audit, Testnet & Launch
Internal security audit with Slither + Mythril, full testnet deployment with real wallet testing, and staged mainnet launch. Collection reveal mechanics verified end-to-end before public mint. Optional third-party audit for high-value launches.
Post-Launch & Monitoring
Subgraph production deployment, on-chain event monitoring, creator dashboard training, and 30 days of direct engineer access. We're on-call for the launch day — the highest-risk moment for any NFT collection.
Questions we get all the time
If yours is not here, reach out. We respond within 24 hours with a real answer from an engineer — not a sales pitch.
ERC-721 for unique 1-of-1s and limited editions. ERC-1155 for collections with multiple editions of each item — gaming assets, trading cards, multi-edition art. ERC-404 for experimental fractionalized NFTs. Metaplex for Solana-native collections. We recommend the standard based on your collection model, not on what we know best.
We implement EIP-2981, the on-chain royalty standard. Every marketplace that respects the standard — OpenSea, Blur (optional), most newer platforms — sends the royalty percentage to your designated address on every secondary sale automatically. We also implement operator filter registry to restrict trading to royalty-respecting platforms when you need stronger enforcement.
Yes — that's exactly what we build. Your own branded marketplace at your domain, with your payment routing, your creator relationships, and your analytics. You keep 100% of marketplace fees instead of sending 2.5% to OpenSea on every sale. Your collectors experience your brand, not a commodity listing page.
We upload metadata and media to IPFS via Pinata (paid pinning for long-term reliability — not free public gateways that disappear). The IPFS CID is embedded in the token URI. Reveal mechanics delay final metadata reveal until mint completes using a hash commitment — the trait distribution can't be gamed before mint closes.
A single-creator mint page with basic gallery and royalty enforcement — 3 to 5 weeks. A full marketplace with auctions, multi-creator support, creator dashboard, and analytics — 7 to 12 weeks. Gaming asset exchanges with real-time attributes and game integration — 10 to 16 weeks. We give you a week-by-week delivery plan in the first meeting.
A single-creator mint platform with gallery and EIP-2981 royalties typically runs $15K–$35K. A full multi-creator marketplace with auctions, creator dashboard, and The Graph analytics lands in the $45K–$120K range. Gaming exchanges with real-time attributes and game integration go higher. We quote a fixed scope after the design phase, with milestone payments — and you keep 100% of marketplace fees afterward.
Ethereum offers the deepest collector base and resale liquidity but higher minting gas. Polygon and Base give near-zero mint costs and are ideal for large drops or mainstream audiences, with full EIP-2981 royalty support. Solana suits high-volume, low-fee collections using Metaplex. We can deploy to any of these — and recommend the chain based on your audience, mint volume, and gas tolerance.
We layer multiple defenses: Merkle-tree allowlist verification, per-wallet and per-transaction mint caps, wallet-age checks, optional CAPTCHA gating, and Dutch-auction pricing to remove the incentive to spam blocks. For high-demand drops we can stage allowlist and public phases. These mechanics keep mints fair for real collectors instead of letting bots sweep the supply in one block.
