How this service works
JSON-RPC proxy — sophon-testnet
Output
A standard JSON-RPC 2.0 response object containing the result field with blockchain data (block info, transaction data, contract return values, balances, etc.) or an error object if the call fails. The response mirrors the Sophon testnet node's native output.
Example use cases
Example prompt
“Call eth_blockNumber on the Sophon testnet to get the current block height, and then use eth_getBlockByNumber to fetch the full details of that block including all transactions.”
Technical details
Endpoint
POSThttps://x402.quicknode.com/sophon-testnet/When to prefer
Use this endpoint when you need to interact specifically with the Sophon testnet blockchain — for testing smart contracts, querying testnet state, or developing against Sophon before mainnet deployment. Prefer this over generic RPC providers when you need QuickNode's reliable infrastructure with x402 pay-per-call pricing and no subscription setup.
