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 |
| eth_getLogs | 20 | 20 | limits the number of eth_getLogs requests per second |
| eth_call | 10 | 200 | limits the number of eth_call requests per second |
| eth_sendRawTransaction | 50 | 500 | limits the number of eth_sendRawTransaction requests per second |
| eth_getTransactionCount | 50 | 500 | limits the number of eth_getTransactionCount requests per second |
| eth_getBlockByNumber | 5 | 500 | limits the number of eth_getBlockByNumber 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
eth_getLogsrequests to catch up latest block can trigger rate limitting. Aseth_getLogsrequest calls are expensive, we recommend adapting the epoch range or block range within your log query filter to reduces request calls.
Other Notes#
- The
eth_getLogsmethod no longer restrict the maximum gap betweenfrom_blockandto_blockfor 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.
