Starknet Chain ID and Testnet/Mainnet Reference
Resolve Starknet chain ID lookups and align indexer/API environments with the correct network identifiers.
This guide covers Starknet chain ID query intent and how to avoid environment mismatches during integration and deployment.
Environment alignment
Keep chain IDs, RPC endpoints, and deployment configuration in one canonical source to prevent accidental cross-network execution.
Indexer recommendation
Index with explicit network labels and include chain ID in API metadata so clients can perform strict environment checks.
