## What it is
The original CryptoPunks project: 10,000 unique algorithmically generated 24x24 pixel collectible characters whose ownership is managed by an Ethereum smart contract with a built-in peer-to-peer marketplace. The repository contains the market contract, its ABI, a verifiable composite image of all punks, and unit tests verifying contract functionality.

## Use cases
- study the pioneering NFT smart contract that predates the ERC-721 standard
- interact with the CryptoPunks market contract using its ABI and contract address
- understand how on-chain ownership and trading of unique digital collectibles works
- fork or reference an early example of a decentralized collectible marketplace
- verify the authenticity of punk images against an on-chain verifiable composite
- research the history of generative pixel art and digital ownership on Ethereum

## When to choose
- You need the canonical contract address and ABI to integrate with or trade CryptoPunks
- You want to study or fork the original pre-ERC-721 NFT implementation
- You are researching the origins of on-chain generative art and NFT marketplaces

## When to avoid
- You need a modern, audited ERC-721/ERC-721A implementation with current tooling
- You want an actively developed NFT framework or SDK rather than a historical artifact
- You need upgradable contracts, minting features, or support for chains other than Ethereum
