Overview

ERC-721 NFT collection on Ethereum Sepolia with IPFS metadata and web-based minting experience.

The Challenge

Digital ownership requires permanence. The challenge was building an NFT ecosystem where not just the token, but the underlying art and metadata are decentralized and censorship-resistant. Furthermore, creating a seamless minting dApp that interacts securely with user wallets via Web3 injection.

The Solution

Solidity ERC-721 with OpenZeppelin, IPFS metadata via Pinata, web minting app with MetaMask integration and on-chain SVG option.

Technical Deep Dive

Decentralized Storage

Pinned image assets and JSON metadata directly to IPFS (InterPlanetary File System), ensuring the art remains available independently of central servers.

Optimized Minting

Wrote gas-efficient ERC-721A smart contracts to minimize network fees for end-users during the minting process.

dApp Integration

Developed a frontend integration using Ethers.js/Wagmi to read contract states, check whitelists, and construct mint transactions directly from the browser.
