description: >-
  Injective provides full test networks (testnet and devnet) that mirror mainnet,
  with public endpoints and a faucet for free test INJ. This is the blockchain
  equivalent of a sandbox: same code paths, valueless test tokens.

selection:
  mechanism: >-
    Sandbox vs live is selected by network (Chain ID + endpoint host), not by a key
    prefix. SDKs accept a Network enum (Mainnet / Testnet / Devnet). The injective-py
    and sdk-ts clients expose network presets that resolve the correct endpoints.

  note: dispenses valueless test INJ to a testnet address for development.
