Where founders get stuck
I don't know if I need white-label or a custom build.
We scope to your goal: white-label to validate in 4–12 weeks for $10K–$50K, custom when you need full control of features, branding, and contracts. Many start white-label and migrate once data proves demand.
My marketplace will launch with no creators or liquidity.
Most marketplaces fail on go-to-market, not tech. We help you scope contract complexity precisely and plan creator acquisition before launch so you don't burn budget on features no one uses yet.
I'm not sure which chains or token standards to support.
We help you pick ERC-721 for one-of-one art or ERC-1155 for editions and gaming items, and validate on one low-fee chain before expanding—each extra chain adds roughly $15K–$40K.
Hidden gas and operating costs will surprise me.
We give you a clear monthly operating budget up front—infrastructure, RPC nodes, indexing, IPFS pinning, and monitoring typically run $2,700–$11,500/month and scale with traffic and chains.
The smart contracts could get exploited.
We build minting, auction, and royalty contracts against real attack vectors and coordinate an independent audit before launch, because deployed contracts are immutable and hold real value.
What we build
ERC-721 and ERC-1155 contracts for minting, listing, auctions, and on-chain royalty logic—built for security and gas efficiency, then audited before any drop goes live.
Lazy minting, batch minting, and creator-friendly minting flows with IPFS or Arweave metadata pinning so assets stay available and tamper-resistant.
Fixed-price sales, English and Dutch auctions, offers, and bundle sales with secondary-sale royalty enforcement that pays creators on every resale.
MetaMask, WalletConnect, and embedded/smart-wallet onboarding plus fiat on-ramps so mainstream buyers can collect without juggling seed phrases or gas tokens.
Indexed search, collections, rarity, trait filters, and trending feeds powered by a fast backend indexer so browsing feels instant despite on-chain data.
An operator panel for commission rates, listings, creator verification, promotions, and analytics—so you can tune monetization without redeploying contracts.
How we deliver
01
We pin down your vertical (art, music, gaming, real estate, ticketing), chain strategy, and white-label vs custom against your budget—then lock scope and a fixed quote.
02
We choose ERC-721 vs ERC-1155, design minting, auction, and royalty logic, and define the security requirements before any code is written.
03
Smart contracts, minting engine, trading/auction system, wallet onboarding, and discovery are built as one integrated stack tuned for gas and UX.
04
An independent audit reviews the contracts line-by-line, and we remediate findings at root cause before real assets and funds touch the platform.
05
We run a closed beta, validate minting, royalties, and withdrawals under real conditions, and help onboard your first creators and collections.
06
Go-live with monitoring, RPC/indexer scaling, and a clear monthly operating budget so your team can run drops and add chains as volume justifies it.
Revenue model
We help you design fee logic that monetizes without scaring off creators or collectors.
A percentage cut—commonly a few percent—taken on each primary and secondary sale routed through your marketplace.
Fees collected when creators mint new NFTs, configurable per collection in the admin panel.
Optional fees for featured placement, homepage promotion, and boosted discovery for creators.
Creators set their own resale royalties while the platform enforces and processes them on every secondary sale.
Fees from curated primary drops and launchpad services for new collections seeking an audience.

OpenSea-comparable multi-chain platform with launchpad, advanced discovery, mobile apps, and multiple audit cycles.
Best for: Funded operators building a flagship marketplace.
Smart-contract development is a major line item: $8K–$20K for basic minting/listing, $25K–$60K for auctions and royalties, and $80K–$200K+ for enterprise protocols. Security auditing adds $5K–$50K+ and should never be skipped. Budget an extra 25–40% for legal, gas operations, and first-year maintenance. Final pricing is fixed after discovery.
Minting, auction, and royalty contracts are audited as a line item in your proposal—never excluded to make a quote look cheaper.
We tell you up front that liquidity and creator acquisition matter more than features, and we scope so you validate demand before over-building.
We build focused vertical marketplaces that serve a real community, and architect for multi-chain expansion once volume justifies the cost.
You get realistic monthly running costs—nodes, indexing, IPFS, monitoring—so there are no surprises after launch.
FAQ
A white-label or basic MVP costs $25,000–$50,000, a mid-complexity custom marketplace $80,000–$200,000, and an enterprise multi-chain platform $250,000–$500,000+. Add 25–40% for legal, gas operations, and first-year maintenance.
A single-chain MVP with minting, listing, and purchase costs $20,000–$50,000 over 3–4 months. A full OpenSea-comparable multi-chain platform with a launchpad, advanced discovery, and audits costs $200,000–$350,000+ over 9–14 months.
The essentials are a smart-contract layer (ERC-721 or ERC-1155), a minting engine, wallet integration (MetaMask/WalletConnect), an auction and fixed-price trading system, a discovery/search layer, and an admin panel with fee management.
A single-chain MVP takes 3–4 months, a mid-level platform 4–7 months, and a multi-chain OpenSea-scale platform 9–14 months. Blockchain integrations, audit cycles, and mobile apps drive the timeline most.
ERC-721 represents unique, one-of-one NFTs where each token is distinct. ERC-1155 is a multi-token standard that can mint many copies of the same item and batch transfers efficiently, making it ideal for gaming items, editions, and tickets. Many marketplaces support both.
Through transaction or commission fees on each sale (commonly a few percent), minting fees, listing or promotion fees, secondary-sale royalty handling, and launchpad or primary-drop fees. The platform takes a cut while creators set their own royalties.
Basic minting and listing contracts cost $8,000–$20,000, mid-complexity auction and royalty systems $25,000–$60,000, and enterprise protocol contracts $80,000–$200,000+. Security auditing adds $5,000–$50,000+ and should never be skipped.
Multi-chain expands your audience, but each additional network adds roughly $15,000–$40,000 depending on VM compatibility. A common path is to validate on one chain—often an EVM Layer 2 for low fees—then expand once real volume justifies it.
Monthly operating costs typically run $2,700–$11,500 covering cloud infrastructure, RPC node providers, indexing APIs, IPFS pinning, and security monitoring. These scale with traffic and the number of chains supported.
Yes. Vertical marketplaces for music royalties, fine art, real-estate fractions, gaming items, or ticketing often outperform generic ones because they serve a focused community. The core tech is similar; the differentiation is in curation, royalty logic, and domain-specific features.
White-label launches in 4–12 weeks for $10,000–$50,000 with limited customization, which is good for proof of concept. Custom builds cost $80,000–$500,000+ over 4–18 months but give full control of features, branding, and smart contracts. Validate with white-label, then build custom once data proves demand.
Most fail from lack of liquidity and creators and weak go-to-market, not bad tech. Avoid it by scoping smart-contract complexity precisely, budgeting honestly for audits, planning creator acquisition before launch, and not over-spending on features before validating demand.
