Rate limiting
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.
rpc.flashbots.net - Flashbots Protect RPC
| Method | Limit |
|---|---|
eth_sendRawTransaction | None |
eth_call | 200 / IP / 5 min |
eth_getTransactionReceipt | 200 / IP / 5 min |
eth_getTransactionByBlockNumberAndIndex | 200 / IP / 5 min |
eth_getBalance | 200 / IP / 5 min |
| All others | 600 / IP / 5 min |
Note that this is requests and not transactions submitted per second. There is no limitation on the number of transactions in a request. Note that you are not required to read JSON RPC requests to send transactions to Flashbots Protect RPC.
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 |
