Thundercore Authentication

Authentication

ThunderCore's public API surface is unauthenticated. The JSON-RPC endpoints (mainnet and testnet, HTTP and WebSocket) and the BlockScout explorer API require no API key — access is controlled by rate limiting (10K/hr on the public mainnet endpoint) rather than credentials. Transaction submission is authorized cryptographically: transactions are signed with the sender's ECDSA (secp256k1) private key per the Ethereum transaction model, with EIP-155 chain-id replay protection (chain ID 108 mainnet / 18 testnet). For hosted key management and social-login auth, the docs point to Particle Network's MPC-based Auth Service as a partner offering.

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