⚠️ ARCHIVED — historical, unmaintained

This repository is archived and should NOT be used.

kcolbchain/contracts is a 2021 fork of create-protocol's NFT-marketplace demo (contracts/NFT.sol + contracts/Marketplace.sol, an old Hardhat toolchain, branch V0). It has not been touched in years.

• Not maintained — no updates, no fixes, no support.
• Not audited — dependencies and Solidity are stale; do not deploy.
• Superseded — the live contract work has moved to ERC721-AI and the current kcolbchain orgs/repos. Use those instead.

This repo is kept only for historical reference. See DEPRECATED.md for details.

Marketplace Contracts (historical)

The content below is preserved as-is from the original 2021 project for reference only. None of it is supported or recommended.

This project demonstrates a basic Hardhat use case. It comes with a sample contract, a test for that contract, a sample script that deploys that contract, and an example of a task implementation, which simply lists the available accounts.

Try running some of the following tasks:

npx hardhat accounts
npx hardhat compile
npx hardhat clean
npx hardhat test
npx hardhat node
node scripts/sample-script.js
npx hardhat help
