- https://www.npmjs.com/package/@imtbl/checkout-sdk
note: >-
  Distinct from the SDKs in packages/. These are client-side, drop-in UI surfaces
  Immutable renders inside a host application — the Checkout widget family and
  the Audience Funnel Page — rather than typed API clients.
families:
- name: Checkout widgets
  docs: https://docs.immutable.com/docs/products/checkout/overview
  loader: '@imtbl/checkout-sdk'
  loader_registry: npm
  loader_version: 2.24.8
  distribution: npm package, mounted into the host app
  components:
  - name: Connect
    purpose: Wallet connection flow (Passport or external wallets).
    docs: https://docs.immutable.com/docs/products/checkout/connect
  - name: Wallet
    purpose: Embedded wallet view — balances and assets.
    docs: https://docs.immutable.com/docs/products/checkout/wallet
  - name: Swap
    purpose: Token exchange on Immutable Chain, routed through QuickSwap.
    docs: https://docs.immutable.com/docs/products/checkout/swap
  - name: Bridge
    purpose: Move tokens between Ethereum L1 and Immutable Chain.
    docs: https://docs.immutable.com/docs/products/checkout/bridge
  - name: Onramp
    purpose: Fiat-to-crypto purchase, fulfilled by Transak.
    docs: https://docs.immutable.com/docs/products/checkout/onramp
  - name: Fund
    purpose: Smart routing that composes onramp + bridge + swap to reach a target token.
    docs: https://docs.immutable.com/docs/products/checkout/fund
  - name: Primary Sales
    purpose: Prebuilt primary-sale (first-mint purchase) flow.
    docs: https://docs.immutable.com/docs/products/checkout/primary-sales
  constraint: >-
    Swap and Bridge widgets only display allowlisted tokens; adding a token
    requires contacting Immutable support.
- name: Audience Funnel Page
  docs: https://docs.immutable.com/docs/products/attribution/funnel-page
  distribution: hosted page plus a one-script-tag embed
  components:
  - name: Funnel Page
    purpose: >-
      Hosted, high-conversion pre-launch landing page that captures email,
      Discord and socials alongside a Steam wishlist click, feeding Audience CDP
      and Attribution.
    hosted_at: play.immutable.com
    custom_domain: true
    custom_domain_docs: https://docs.immutable.com/docs/products/attribution/funnel-page-custom-domain
  - name: Sign-up drawer embed
    purpose: The Funnel Page sign-up drawer dropped into an existing marketing site.
    integration: single script tag
    docs: https://docs.immutable.com/docs/products/attribution/funnel-page-embed
    versioning: >-
      The docs describe the embed as "one script tag" without a pinned version in
      the published snippet, so a consumer cannot tell which build they load.
- name: Web component (legacy)
  docs: https://github.com/immutable/gu-composited-card
  distribution: GitHub repository
  components:
  - name: gu-composited-card
    purpose: >-
      Framework-agnostic web component for displaying Gods Unchained composited
      cards.
    official: true
    note: >-
      First-party but game-specific and from the Immutable X era; not part of the
      current platform surface.
web_components_standard: false
web_components_note: >-
  Apart from gu-composited-card, the Checkout family is a React/JS widget SDK
  rather than a set of custom elements, so it cannot be dropped into a
  non-JavaScript page the way a true web component can.
