name: Mina Sandbox Node
summary: >-
  A single-node private Mina network packaged with Docker that uses the same
  configuration as the live testnet. Supports multiple accounts, sending
  transactions between them, SNARK work, delegating, and staking. Because it is
  a single-node network the operator earns all block rewards. It does NOT connect
  to a live network.

notes: >-
  Test values (accounts, keys) are generated locally by the sandbox rather than
  published as fixed magic identifiers. No hosted sandbox API keys exist because
  the GraphQL API is bound to localhost.
