Unichain RPC connects applications to Unichain through JSON-RPC over HTTPS or WebSocket. Read balances and contract state, retrieve event logs, and submit signed transactions. See Unichain developer documentation.
Create a free Chainstack account, create a project, and deploy a Unichain Global Node on mainnet or Sepolia. Copy your HTTPS or WebSocket URL from Access and credentials. The Developer plan includes 3 million request units per month, up to 25 requests per second, and one node. No credit card is required.
Your mainnet HTTPS URL follows https://unichain-mainnet.core.chainstack.com/YOUR_ENDPOINT_ID. Sepolia uses https://unichain-sepolia.core.chainstack.com/YOUR_ENDPOINT_ID. Copy the complete authenticated URL from your node and replace the example endpoint ID. See the Unichain tooling guide.
Unichain Mainnet uses chain ID 130 (0x82). Unichain Sepolia uses 1301 (0x515). The gas currency is ETH. Use the chain ID matching your endpoint when configuring a wallet or signing transactions. See the official network details.
Yes. Chainstack supports Unichain Mainnet and Sepolia. Deploy a separate node for each network and use the matching chain ID and endpoint. Sepolia ETH is for testing and has no mainnet monetary value. Check supported networks.
Yes. Configure your wallet or library with your Unichain RPC URL and chain ID. Use HTTPS for JSON-RPC requests and your WSS URL for supported subscriptions such as new blocks and contract logs. Follow the Unichain tooling guide.
Chainstack supports Unichain archive access on mainnet and Sepolia. Archive state supports historical contract reads and analytics. Archive requests are billed at 2 request units; the exact classification depends on the method and block age. Archive access is available from Growth. See request-unit rules and supported network modes.
Use a Unichain node with debug and trace APIs enabled on a paid plan. Inspect transaction execution to investigate reverted calls and contract behavior. See Unichain debug requirements.
Unichain supports Flashblocks preconfirmations. Applications can read preconfirmed state using the pending block tag through an RPC provider that supports Flashblocks. Preconfirmation is not Ethereum settlement or finality. This network capability does not mean every provider endpoint exposes the same preconfirmation data. See the official Flashblocks integration guide.
Call eth_getLogs with a bounded block range and the event topics you need. ERC-20 transfers use the standard Transfer(address,address,uint256) event signature. Filter by contract address for a specific token, and paginate larger backfills. The request uses standard Ethereum-compatible event-log parameters.
Start with the free Developer plan. Paid plans start at $40 per month with annual billing. Unlimited Node adds flat-fee request capacity from Growth. Dedicated Nodes require Pro or above, with infrastructure billed separately. Compare current plan features.
Yes. Chainstack Self-Hosted supports Unichain Mainnet and Sepolia with OP-Reth and OP-Node. You supply Ethereum L1 RPC and Beacon API endpoints for L2 derivation. Review the supported deployments and installation guide.
Connect to Unichain Mainnet at https://unichain-mainnet.core.chainstack.com/YOUR_ENDPOINT_ID. Copy the authenticated URL from Access and credentials. Mainnet uses chain ID 130 and ETH for gas. Sepolia uses https://unichain-sepolia.core.chainstack.com/YOUR_ENDPOINT_ID and chain ID 1301. See the Unichain tooling guide.
Use eth_getBalance for ETH balances, eth_call for contract reads, eth_getLogs for event history, and eth_sendRawTransaction for signed transactions. Connect over WebSocket for supported new-block and log subscriptions. For swap analytics, collect and decode contract events as shown in the Uniswap v4 trade-indexing guide.
