Rate Limits
In order to protect our services from abuse we have rate limits on the number of requests that can be made. Currently, the rate limits are set as follows.
relay.flashbots.net - Bundles
| Method | Limit |
|---|---|
eth_sendBundle | 1800 / IP / 1 min |
mev_sendBundle | 1800 / IP / 1 min |
eth_cancelBundle | 600 / IP / 1 min |
mev_simBundle | 300 / IP / 1 min |
eth_callBundle | 300 / IP / 1 min |
| All others | 120 / IP / 1 min |
Note that this is requests and not transactions submitted per second. There is no limitation on the number of transactions in a request.
RPC rate limits for retail user transactions sent to rpc.flashbots.net can be found here.
Rate limit exceptions
If you require a higher rate limit please reach out to Shea Ketsdever.
