Transaction Auditing

Protecting the Flow community, one transaction at a time.

How Does it Work?
Emerald City hosts a FLIX instance. In short, FLIX is a place to store audited transactions. Anyone can host their own FLIX instance. When a transaction gets run, wallets can query into FLIX instances they trust and display associated audits.
Fortunately, Emerald City's FLIX instance is a peer of Flow, meaning any transactions hosted by Flow are automatically hosted by Emerald City, and vice versa. Note this doesn't necessarily mean the other has audited them, rather they will simply be discoverable from either's endpoint.
Shield's API
Get Template by ID
With the API you can query Interaction Template by their ID:
GET /v1/templates/${template_id}
  => InteractionTemplate
Get Template by Cadence Code
You can also query for Interaction Template by their cadence body:
POST /v1/templates/search
  body (JSON): {
    cadence_base64: "...",
    network: "..." (mainnet | testnet)
  }
  => InteractionTemplate
Get Template by Name
Interaction Template can be hosted under a static identifer (name), allowing the underlying Interaction Template to change while the way to query for it remained constant:
GET /v1/templates?name=transfer-flow
  => InteractionTemplate
Get Auditor
You can query for known Auditor information for a given network:
GET /v1/auditors?network=(mainnet | testnet)
  => [FlowInteractionTemplateAuditor]
​
  // Flow Interaction Template Auditor
  // {
  //   f_type: "FlowInteractionTemplateAuditor"
  //   f_version: "1.0.0"
  //   address: string
  //   name: string
  //   website_url?: string
  //   twitter_url?: string
  // }
