Flashbots RPC client

Fork of ethrpc with additional Flashbots RPC methods:

  • FlashbotsCallBundle (eth_callBundle)
  • FlashbotsSendBundle (eth_sendBundle)
  • FlashbotsGetUserStats (flashbots_getUserStats)
  • FlashbotsSendPrivateTransaction (eth_sendPrivateTransaction)
  • FlashbotsCancelPrivateTransaction (eth_cancelPrivateTransaction)
  • FlashbotsSimulateBlock: simulate a full block

Usage

Add library to your project:

go get github.com/metachris/flashbotsrpc

Create a new private key here for testing (you probably want to use an existing one):

privateKey, _ := crypto.GenerateKey()
Simulate transactions with eth_callBundle:
callBundleArgs := flashbotsrpc.FlashbotsCallBundleParam{
    Txs:              []string{"YOUR_RAW_TX"},
    BlockNumber:      fmt.Sprintf("0x%x", 13281018),
    StateBlockNumber: "latest",
}

result, err := rpc.FlashbotsCallBundle(privateKey, callBundleArgs)
if err != nil {
    log.Fatal(err)
}
fmt.Printf("%+v\n", result)
Get Flashbots user stats:
rpc := flashbotsrpc.New("https://relay.flashbots.net")
result, err := rpc.FlashbotsGetUserStats(privateKey, 13281018)
if err != nil {
    log.Fatal(err)
}
fmt.Printf("%+v\n", result)
Send a transaction bundle to Flashbots with eth_sendBundle:
sendBundleArgs := flashbotsrpc.FlashbotsSendBundleRequest{
    Txs:         []string{"YOUR_RAW_TX"},
    BlockNumber: fmt.Sprintf("0x%x", 13281018),
}

result, err := rpc.FlashbotsSendBundle(privateKey, sendBundleArgs)
if err != nil {
    log.Fatal(err)
}
fmt.Printf("%+v\n", result)
