🔹Public RPC Specs

Orbion Testnet provides high-availability JSON-RPC endpoints that are fully compatible with the Ethereum RPC standard. These endpoints are intended for developers, dApps, indexers, and wallets seeking quick access to blockchain state, transactions, and contract interaction — without running a full node.
