NFT Development Skill

Master NFT development with token standards, metadata design, marketplace integration, and on-chain generative art.

Quick Start

# Invoke this skill for NFT development
Skill("nft-development", topic="standards", standard="ERC721A")

Topics Covered

1. Token Standards

Choose the right standard:

• ERC-721: Standard NFTs, one token per ID
• ERC-721A: Gas-optimized batch minting
• ERC-1155: Multi-token, semi-fungible
• DN404: Divisible NFT hybrid

2. Metadata Design

Structure your NFT data:

• On-chain: Base64 JSON, SVG
• IPFS: Content-addressed storage
• Arweave: Permanent storage
• Dynamic: Evolving traits

3. Marketplace Integration

List and sell NFTs:

• OpenSea: Seaport protocol
• Royalties: EIP-2981
• Operator Filter: Royalty enforcement
• Collection Verification: Metadata standards

4. On-Chain Art

Generate art in Solidity:

• SVG Generation: Dynamic shapes
• Seed-based: Deterministic randomness
• Traits: Rarity distribution
• Base64: Data URI encoding

Code Examples

ERC-721A Mint

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.24;

import "erc721a/contracts/ERC721A.sol";
import "@openzeppelin/contracts/access/Ownable.sol";

contract MyNFT is ERC721A, Ownable {
    uint256 public constant MAX_SUPPLY = 10000;
    uint256 public constant PRICE = 0.08 ether;

    error MaxSupplyReached();
    error InsufficientPayment();

    constructor() ERC721A("MyNFT", "MNFT") Ownable(msg.sender) {}

    function mint(uint256 quantity) external payable {
        if (_totalMinted() + quantity > MAX_SUPPLY) revert MaxSupplyReached();
        if (msg.value < PRICE * quantity) revert InsufficientPayment();

        _mint(msg.sender, quantity);
    }

    function _startTokenId() internal pure override returns (uint256) {
        return 1;
    }
