Public RPCs endpoints

Public available Conflux network RPC endpoints

Confura

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.

Rate Limits

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 429.

Method	QPS	Burst	Comment
all	100	1000	limits the number of all requests per second
cfx_getLogs	20	20	limits the number of cfx_getLogs requests per second
cfx_call	10	200	limits the number of cfx_call requests per second
cfx_sendRawTransaction	50	500	limits the number of cfx_sendRawTransaction requests per second
cfx_getNextNonce	50	500	limits the number of cfx_getNextNonce requests per second

If you are in the demand for higher QPS need, please visit Conflux Hub to purchase our VIP subscription plan (testnet supported only for the moment) with the following new QPS standards.

cfx_getLogs	40	40	limits the number of cfx_getLogs requests per second
cfx_call	20	200	limits the number of cfx_call requests per second
cfx_sendRawTransaction	50	500	limits the number of cfx_sendRawTransaction requests per second
cfx_getNextNonce	100	500	limits the number of cfx_getNextNonce requests per second

Common causes and mitigations

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_getLogs requests to catch up latest epoch can trigger rate limitting. As cfx_getLogs request calls are expensive, we recommend adapting the epoch range or block range within your log query filter to reduces request calls.

Other Notes

• The cfx_getLogs method no longer restrict the maximum gap between from_epoch and to_epoch for 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.
