Before you choose

Requirements & limits

The repository is publicly accessible, identified as open source and licensed under MIT. No account, pricing or service-availability requirements are documented here.

  • The workspace uses TypeScript and includes JavaScript-facing Solana tooling.
  • It supports Web, Server and CLI development contexts.
  • The repository requires Just, Node.js 20.19 or later, and pnpm 10 for the documented development setup.
  • New development is on v3-plus; the maintenance/v1.x branch is for legacy version 1.x and receives critical fixes only.
  • The workspace includes both the core Solana JavaScript API and a wallet-adapter package.

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