Project Overview

A collective of digital artists required a curated marketplace to mint, list, and trade NFTs securely. We designed smart contracts, a web3 dApp, and off‑chain indexing to deliver a seamless, secure experience.

Challenges

  • Security and trust for minting/listing auctions
  • Gas cost optimization and UX for wallet flows
  • Indexing collections and activity feeds

Neuradigi Solution

We built audited ERC‑721 contracts, auction logic, and a performant React dApp with wallet support.

1
Smart Contracts: ERC‑721 minting, transfers, royalties; audit and tests.
2
Auction Logic: Fixed‑price and timed auctions with transparency.
3
Web3 Front‑End: React dApp, wallet connect, collection management.

Business Outcomes

  • Zero critical vulnerabilities at launch
  • 10k early users onboarded
  • Seamless mint/list/bid flows with wallet support

Approach & Architecture

  • Contracts: ERC‑721, marketplace, royalty splitters with tests.
  • Storage/Index: IPFS for assets, The Graph for fast queries.
  • DApp: React + Ethers.js, wallet connect, network handling.
  • Security: Audits, reentrancy protection, pausable modules.
High-level architecture for NFT marketplace

Security and UX were our top concerns. Neuradigi delivered both. Launch was smooth and adoption strong. Excellent execution.
