test_mode:
  description: >-
    The testnet environment is not settled and uses mock assets, so it functions as the public
    sandbox for building and testing against the Bullet Trading API without real funds. Generate an
    ed25519 delegate keypair, register it as a delegate account, and point clients at the testnet
    host to place and manage orders end-to-end.
  keypair: Generate an ed25519 delegate keypair locally (or via the app's "Generate" button) and register it as a Delegate Account.
notes: >-
  No published test card numbers or magic values (Bullet is a derivatives/spot/lending DEX, not a
  card acquirer). The sandbox is the testnet environment plus delegate-account key generation.
