HelaMesh JS SDK

Embed the HelaMesh checkout directly inside your own page. The SDK is a tiny script (~8kb gzipped) that mounts an iframe-based widget you control via JavaScript callbacks. No payment UI to build.

The model is the same as Stripe Elements: your server creates the invoice and gets back an ID, then your browser code uses that ID plus a publishable key to render the payment widget. The customer never leaves your site.

CDN URL

The SDK is loaded from https://pay.helamesh.com/sdk/v1.js. Pin to a major version (v1) for automatic minor/patch updates without breaking changes.

Two components​

The SDK exposes two functions:

  • HelaMesh.mount(target, options) — render the checkout embed for an invoice you've already created
  • HelaMesh.renderChainPicker(target, options) — render a chain picker so the customer chooses a network before you create the invoice

Use the chain picker when you want to offer multiple chains (TRON + BSC). Use mount directly when you've already decided the chain server-side.
