Understand the project

Practical overview

When it fits

Use it when an NFT project needs on-chain image and trait generation with rendering or data logic that can be reused across instances.

Who it is for

  • Smart-contract developers building NFT collections with on-chain images and traits.
  • Developers creating reusable SVG rendering or on-chain data modules.
  • Teams developing interfaces for managing SVG and data-stream registries.

Documented uses

  • Generate token images and traits on-chain.
  • Compose reusable SVG modules across NFT instances.
  • Manage rendering modules through an SVG registry.
  • Fetch dynamic on-chain data through stream modules and a data-stream registry.
Before you choose

Requirements & limits

The project is available as a public GitHub repository. Its README recommends pnpm for installation.

  • Rendering and dynamic on-chain data are managed through separate smart-contract registries.
  • The repository separates apps, contracts and packages in a TypeScript monorepo.
  • The README documents pnpm, Turborepo task pipelines, local development and a blockchain-fork development command.
  • Module-specific environment variables are needed for deployment or blockchain-fork preparation.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Set up the ERC721K monorepo for local development

Install the repository dependencies and start the documented local development workflow.

Before you start

  • A local development environment with pnpm installed.
  • The repository README recommends pnpm as its package manager.

Steps

  1. Clone the repository.

  2. Run pnpm install.

  3. Run pnpm lab for local development.

Expected outcome

The README's dependency installation and local-development command sequence is complete.

Guide limitations

  • The README does not specify the environment requirements for every module.
  • Modules require their own environment variables when preparing for deployment or a blockchain fork.
