Skale Labs Authentication

Authentication

SKALE surfaces are Ethereum-compatible JSON-RPC endpoints and SDKs, not key-authenticated REST APIs. Public JSON-RPC RPC endpoints (skalenodes.com) require no API key. State-changing operations are authenticated cryptographically: transactions are signed with an EVM wallet private key (ECDSA/secp256k1) and gas is paid via sFUEL / CREDITs rather than an account token.

Skale Labs secures its APIs with none and wallet-signature across 3 declared security schemes, as derived from its OpenAPI definitions.
