Before you choose

Requirements & limits

The repository is public and MIT-licensed. The README documents an external embed script and a local npm-based development setup.

  • The recipient must be configured as a Lightning Address or LNURL.
  • The documented widget supports display customization and initialization-time settings validation.
  • The README documents an embed-script approach; it does not lay out a complete payment transaction flow.

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