A Cronos RPC endpoint connects your application to Cronos EVM through Ethereum-compatible JSON-RPC. Use it to read balances and contract state, retrieve event logs, estimate gas, and send signed transactions. Cronos EVM is separate from Cronos POS and Cronos zkEVM. See the Cronos tooling guide.
네. Chainstack의 개발자 요금제에는 월 300만 건의 request units , 초당 25건의 요청, 그리고 node 1개가 포함되어 있으며, 신용카드 등록이 필요하지 않습니다. 요청 단위 사용량은 메서드에 따라 다릅니다. 무료 계정을 만들거나 요금제 기능을 비교해 보세요.

Cronos Mainnet uses chain ID 25. Cronos Testnet uses chain ID 338. These are Cronos EVM networks, not Cronos POS or Cronos zkEVM. See the Cronos tooling guide for connection examples.
Yes. Use the WebSocket URL in your node’s Access and credentials panel with eth_subscribe to follow new blocks and contract logs. Use HTTPS and eth_getLogs for historical backfills, and reconnect and catch up after a dropped subscription. See the Cronos connection examples.
Paid Cronos Global Nodes expose debug_traceTransaction, debug_traceCall, debug_traceBlockByNumber, 그리고 debug_traceBlockByHash. Cronos does not serve the trace_* namespace. On Cronos Mainnet archive nodes, debug_traceBlockByNumber is limited to 10 requests per second on all plans. See Cronos debug API availability.
Yes. Cronos 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. Chainstack Self-Hosted supports Cronos Mainnet and Testnet using cronosd. Deploy on infrastructure you control and manage the node through the Chainstack Self-Hosted interface. Hosting resources remain your responsibility. See the installation guide 그리고 supported deployment catalog.
Connect your application to Chainstack’s Cronos HTTPS endpoint to read balances, call contracts, query event logs, and submit signed transactions. Use eth_call 계약서 열람의 경우, eth_getLogs 행사 관련 문의는, eth_getTransactionReceipt 수령 확인을 위해, 그리고 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. 바꾸기 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 그리고 RPC 메서드 참조 통합에 대한 자세한 내용은 다음을 참조하십시오.
