🎨 Dynamic Token Images and Metadata

ERC721K - Dynamic Token Images and Metadata

Overview

ERC721K is an ERC721 implementation with zero dependencies for off-chain data.

Both the token image and token traits are generated entirely on-chain.

However, instead of the smart contract logic deployed in a specific NFT instance, the underlying system has been modularized, to enable composition of SVGModules across many different instances. NFTs can share SVGModules which encapsulate both rendering and data fetching logic.

How It Works

Image and Metadata (traits) are dynamically generated using the SVGRegistry and DataStreamRegistry smart contracts.

SVGRegistry

The SVGRegistry manages SVGModules and provides a unified interface for rendering dynamic SVGs.

DataStreamRegistry

The DataStreamRegistry manages StreamModules and provides a unified interface for fetching dynamic on-chain data.

Installation & Usage

git clone [email protected]:turbo-eth/turbo-eth.git

Installation

pnpm is the recommended package manager.

pnpm install

Local Development

pnpm lab

Local Development w/ Blockchain Fork

pnpm lab:fork

Build

pnpm build

Tests

pnpm test

Modules

The monorepo includes 3 primary folders.

• apps
• contracts
• packages

Each folder contains similar modules i.e. frontend applications go in the apps folder and the smart contracts go in the contracts folder; very straight-forward.

Environment Variables

Each module requires unique environment variables. Specifically the apps and contracts modules when preparing for deployment or forking a blockchain network.

The .env.example can be copied/pasted and updated to include the required variables deployment.

Task Pipelines

Builds, tests and deployments are handled via tasks pipelines. Task pipelines orchestrate build and dependency requirements between mono-repo packages.

Edit the turbo.json file in the root directory to add new pipelines and custom workflows.

Developer Experience

The TurboETH build system uses Turborepo and pNPM; a high-performance build system and a fast, disk space efficient package manager. Giving developers the best experience possible while minimizing demand on local compute resources.
