🔹Public RPC Endpoints

Orbion provides stable, public JSON-RPC endpoints for developers, validators, and indexers. These endpoints are load-balanced, rate-limited, and designed to mimic mainnet conditions on testnet — offering high availability and reliable connectivity.

No authentication required. Ready out of the box.

🔍 Tips for Developers

• Rate limits are shared per IP — use local node for large batch requests.

• If deploying contracts, ensure you’re sending signed raw transactions (eth_sendRawTransaction) for best results.
