Public available Conflux network RPC endpoints
Confura is an Ethereum Infura equivalent public JSON-RPC service on Conflux network, which is developed and maintained by Conflux foundation.
Our public RPC services are located in different regions globally. By utilizing geographic DNS routing, developers can request the regional RPC services which are physically closest to them.
To ensure the service availability, we've added several rate limiters (implemented with token bucket algorithm) to mitigrate against bursts of incoming traffic. Users who send many requests in quick succession may see error responses that show up as status code
|all||100||1000||limits the number of all requests per second|
|cfx_getLogs||20||20||limits the number of |
|cfx_call||10||200||limits the number of |
|cfx_sendRawTransaction||50||500||limits the number of |
|cfx_getNextNonce||50||500||limits the number of |
Rate limiting can occur under a variety of conditions, but it’s most common in these scenarios:
- Issuing multiple state call requests all at once can lead to rate limitting. We recommend using
Multicall, which aggregates results from multiple contract constant function calls, and reduces the number of separate JSON RPC requests that need to be sent.
- Running high frequency
cfx_getLogsrequests to catch up latest epoch can trigger rate limitting. As
cfx_getLogsrequest calls are expensive, we recommend adapting the epoch range or block range within your log query filter to reduces request calls.
cfx_getLogsmethod no longer restrict the maximum gap between
to_epochfor log query filter. Instead the query is now bounded with reasonable queryset size, 3s maximum running time and no more than 10,000 resultset size, under other circumstance you may need to narrow down your search condition.
