A Sonic RPC endpoint connects your application to Sonic through Ethereum-compatible JSON-RPC. Use it to read balances and contract state, query event logs, estimate gas, and send signed transactions. Sonic Mainnet uses chain ID 146 and S for gas. See the Sonic tooling guide.
Yes. Chainstack’s Developer plan includes 3 million request units per month, 25 requests per second, and one node, with no credit card required. Request-unit consumption depends on the method. Create a free account or compare plan features.
Mainnet: https://sonic-mainnet.core.chainstack.com/YOUR_ENDPOINT_ID.
Testnet: https://sonic-testnet.core.chainstack.com/YOUR_ENDPOINT_ID.
Replace YOUR_ENDPOINT_ID with the identifier from your node’s Access and credentials panel. Keep that identifier private and use the complete URL supplied for your deployed network. Get a Sonic endpoint.
Sonic Mainnet uses chain ID 146. The current Sonic Testnet uses chain ID 14601. Match the chain ID to the network selected for your RPC endpoint. See Sonic’s official network settings.
No. The current Sonic Testnet uses chain ID 14601, while legacy Blaze Testnet uses 57054. Do not reuse a Blaze chain ID or endpoint URL for the current Testnet. Check your deployed node’s network and use the matching connection details. See Sonic’s current Testnet settings.
Yes. Connect ethers.js, viem, web3.py, Hardhat, or Foundry to the HTTPS endpoint for your Sonic network. Use standard EVM methods such as eth_call, eth_getLogs, and eth_sendRawTransaction. See the Sonic tooling guide for integration examples.
Yes. Sonic archive access is available on paid plans for historical contract-state reads. Event-log retrieval and historical state are different workloads: specify the block you need for state queries, and paginate log backfills. Available historical ranges depend on the node configuration and retained data. See supported networks and node modes.
Yes. On a paid plan, deploy a Sonic Global Node with debug and trace APIs enabled. Use execution traces to investigate reverted calls and internal contract activity. Check the supported methods and deployment requirements before choosing your node configuration.
Yes. Chainstack Self-Hosted supports Sonic Mainnet and the current Sonic Testnet using sonicd. Deploy on infrastructure you control and manage the node through the Chainstack Self-Hosted interface. Hosting resources remain your responsibility. See the installation guide and supported deployment catalog.
Connect your application to Chainstack’s Sonic HTTPS endpoint to read balances, call contracts, query event logs, and submit signed transactions. Use eth_call for contract reads, eth_getLogs for event queries, eth_getTransactionReceipt for receipt checks, and eth_sendRawTransaction to broadcast a signed transaction. Sonic Mainnet uses chain ID 146. The current Sonic Testnet uses chain ID 14601.
A Chainstack Sonic Mainnet endpoint follows the format https://sonic-mainnet.core.chainstack.com/YOUR_ENDPOINT_ID. Replace YOUR_ENDPOINT_ID with your own authenticated node identifier. Use ethers.js, viem, or web3.py to build DeFi interfaces, trading systems, and historical analytics. Filter event logs by contract address and topic, and keep historical block ranges bounded. See the Sonic tooling guide and RPC method reference for integration details.
Legacy Blaze Testnet uses chain ID 57054 and is separate from the current Sonic Testnet. Match your node’s network, endpoint URL, and chain ID before submitting transactions.
