Along with the other api calls we can make to Skandha, users can manually submit a UserOperation by making a POST request to one of our bundlers. With a valid UserOp created, we pass this into the params field along with the entrypoint contract address. Example curl request: 
curl --request POST \
  --url https://testnet-rpc.etherspot.io/v1/114 \
  --header "Content-Type: application/json" \
  --data '{

On successful submission to the bundler we will receive a UserOp hash. 
{"result":"0x7b1d33806fcf983834da03abb71a75ac242076aacfa8b376dbc50565ca77f72e"}
The transaction will then be processed 30-40 seconds after this.
