Get your transaction sent to multiple regions in a single call with these two RPC methods. Using this method will cost 70 API credits per call.

Prevents common issues with single node transaction broadcasting where things like low peer counts, full mempools, and network issues, cause dropped transactions.

The multi-region transaction broadcast add on provides a JSON-RPC method that works exactly like eth_sendRawTransaction but guarantees your transaction is sent to multiple regions for the given chain.

Using this method will cost 70 API credits per call.
