Injective Authentication

Authentication

Injective's public read APIs (Chain LCD/REST, Tendermint RPC, and the Indexer gRPC/gRPC-web/REST + Chain Stream WebSocket) are open, permissionless endpoints that require no API key or OAuth token — they are rate-limited public infrastructure. WRITE access is not key-based: state changes are performed by broadcasting cryptographically signed transactions. Signing uses either native Cosmos secp256k1 (bech32 inj1... accounts) or Ethereum EIP-712 typed-data signing (0x... keys), with optional AuthZ grant delegation for session-based auto-signing.

Injective secures its APIs with none-public and signature-based-transactions across 4 declared security schemes, as derived from its OpenAPI definitions.
