  title: BitGo Platform Addresses Transactions API
  description: Representative specification of the BitGo Platform REST API v2 for institutional digital-asset custody. Covers wallets, addresses, transactions and transfers, keychains, webhooks, wallet policies, staking, trading and settlement over the Go Network, and enterprise / user surfaces. Most endpoints are namespaced under a coin (for example `btc`, `eth`, `hteth`) via the `{coin}` path parameter. Authentication uses a Bearer access token. Transaction-signing operations that require private-key material are typically issued against a self-hosted BitGo Express proxy.
