AsyncAPI Specification

spec_type: Webhooks
surface: websocket
description: >-
  ShapeShift unchained provides realtime updates about blockchain transactions
  (pending and confirmed) over a WebSocket interface, alongside its REST API, on
  the same per-chain api.<chain>.shapeshift.com hosts. Clients subscribe to an
  address (pubkey) and receive transaction events as they enter the mempool and
  as they confirm. The first-party @shapeshiftoss/unchained-client library wraps
  this WebSocket subscription surface.
events:
- name: transaction
  trigger: A transaction affecting a subscribed address is observed.
  states: [pending, confirmed]
  keyed_by: pubkey (subscribed address)
delivery:
  transport: websocket
  model: subscribe/push
  auth: none (public)
notes: >-
  Captured as a Webhooks/event-surface artifact: the realtime transaction
  subscription is documented in the unchained project and implemented by the
  official client, but ShapeShift does not publish a formal AsyncAPI document or
  a per-message JSON schema, so no AsyncAPI spec is saved (none is fabricated).
  The concrete WebSocket URL path and message schema should be read from
  @shapeshiftoss/unchained-client.
