Lossless NFTs

Ethereum dApp allowing for nft-based experiments in mechanism design.

Project built with scaffold eth.

Only part of the intended functionality is available so far, but

Try it out on Rinkeby 🤩

Concept: Create and manage NFTs with up-only price

Special ERC721 contract that twists the usual meaning of NFT ownership. Extra incentives are added such that the price can only ever increase.

Actors

• Author
• Minter
• Grabber

Author creates NFT.

Sets

• minimum price
• author fee (% or fixed)

=> NFT becomes visible in app gallery. Can be minted by anyone.

Minter mints NFT.

Sets

• price (>= minimum price)
• premium (% value)
• pays the price in order to mint
• author receives these funds

Grabber takes NFT permissionlessly

• Anyone can grab an NFT
• Grabbing requires to pay the grabPrice = price + premium
• Grabber becomes the new owner
• Previous owner receives the payment
• grabPrice increases by the premium that was just paid (price premium compounds across grabs)

Locking mechanism

An owner can lock/unlock the asset. Only the owner can do this.

Unlocking disables all the grab-related functionality. Then the asset becomes a regular NFT.

Locking is associated with a fee (the author fee). Everytime an asset is locked the author gets paid that fee.

If the author fee is set as %, it's always calculated relative to the current grabPrice of the asset.

WIP (not done yet)

• as a user I can author an asset

  • upload to IPFS
  • specify metadata
  • set minPrice and author fee

• as a user I can see all assets from a given author

  • organize the gallery page based on a specific author
  • these pages should be shareable/bookmarkable
  • needs backend support (probably firebase storage for an MVP)

• lock / unlock feature

🏗 Scaffold-ETH

everything you need to build on Ethereum! 🚀

🧪 Quickly experiment with Solidity using a frontend that adapts to your smart contract:

🏄‍♂️ Quick Start

Prerequisites: Node plus Yarn and Git

clone/fork 🏗 scaffold-eth:

git clone https://github.com/austintgriffith/scaffold-eth.git

install and start your 👷‍ Hardhat chain:

cd scaffold-eth
yarn install
yarn chain

in a second terminal window, start your 📱 frontend:

cd scaffold-eth
yarn start

in a third terminal window, 🛰 deploy your contract:

cd scaffold-eth
yarn deploy

🔏 Edit your smart contract YourContract.sol in packages/hardhat/contracts

📝 Edit your frontend App.jsx in packages/react-app/src

💼 Edit your deployment scripts in packages/hardhat/deploy

📱 Open http://localhost:3000 to see the app
