NFT Marketplace Development.
We build NFT marketplaces and tokenised-asset platforms: minting and collection management, listings and auctions, royalties and fees, wallet connection and fiat on-ramps, plus the indexer and backend that make on-chain data fast to browse. Our marketplace backend project covered minting, trading and collection APIs over EVM chains.

How we build it.
The on-chain part of a marketplace is small and must be boring; the off-chain part is where the user experience lives. We keep contracts minimal and audited, and build an indexer that turns chain events into a queryable database so pages load instantly and search works. Everything a user sees comes from the index; everything that moves value goes through the contracts.
- 01
Minimal, audited contracts based on established standards rather than custom logic
- 02
Event-driven indexer with reorg handling and backfill for historical data
- 03
Off-chain order books and signatures to keep listing free and fast
- 04
Chain-agnostic backend so new EVM networks can be added by configuration

Frequently asked questions.
01Which chains do you support?
Ethereum and EVM-compatible networks (Polygon, Base, Arbitrum, BNB Chain and others) as a default; Solana and others on request. The backend is designed so adding a network is configuration, not a rewrite.
02Do you audit the smart contracts?
We write tests and perform internal review, and we coordinate an external audit before mainnet launch. Keeping contracts minimal and standards-based keeps audit scope and cost small.
03Can mainstream users buy without a crypto wallet?
Yes. We integrate fiat on-ramps and custodial wallet options so users can sign up with email and pay by card, while advanced users connect their own wallets.
04What does an NFT marketplace cost?
A collection with a basic marketplace starts around 45k USD over 10–14 weeks. Full marketplaces with auctions, royalties, on-ramps and moderation are typically in the 90–180k range.
