Connect your application to Chainstack’s Cronos HTTPS endpoint to read balances, call contracts, query event logs, and submit signed transactions. Use eth_call đối với các lần đọc theo hợp đồng, eth_getLogs để hỏi về sự kiện, eth_getTransactionReceipt để kiểm tra hóa đơn, và eth_sendRawTransaction to broadcast a signed transaction. Cronos Mainnet uses chain ID 25. Cronos Testnet uses chain ID 338.
A Chainstack Cronos Mainnet endpoint follows the format https://cronos-mainnet.core.chainstack.com/YOUR_ENDPOINT_ID. Thay thế YOUR_ENDPOINT_ID with your own authenticated node identifier. Use ethers.js, viem, or web3.py to build DeFi interfaces, trading systems, and wallet backends. WebSocket subscriptions can follow new blocks and contract logs; use bounded HTTPS log requests for historical backfills. See the Cronos tooling guide và Tham chiếu phương thức RPC để biết thêm chi tiết về việc tích hợp.
