💾 Installing

go get github.com/weeaa/jito-go@latest

If you want to run tests:

1. Install Task.
2. Initialize your .env file by running task install:<os> (darwin/linux/windows).
3. Run tests with task test.

🔑 Keypair Authentication

To access Jito MEV functionalities, you'll need a whitelisted Public Key obtained from a fresh KeyPair; submit your Public Key here. In order to generate a new KeyPair, you can use the following function GenerateKeypair() from the /pkg package.

💻 Examples

Send Bundle

package main

import (
  "context"
  "github.com/17535250630/solana-go"
  "github.com/17535250630/solana-go/programs/system"
  "github.com/17535250630/solana-go/rpc"
  "github.com/weeaa/jito-go"
  "github.com/weeaa/jito-go/clients/searcher_client"
  "log"
  "os"
)

func main() {
  client, err := searcher_client.NewSearcherClient(
    jito_go.NewYork.BlockEngineURL,
    rpc.New(rpc.MainNetBeta_RPC),
    solana.MustPrivateKeyFromBase58(os.Getenv("PRIVATE_KEY")),
	nil,
  )
  if err != nil {
    log.Fatal(err)
  }

  // max per bundle is 5 transactions
  txns := make([]*solana.Transaction, 0, 5)

  block, err := client.RpcConn.GetRecentBlockhash(context.TODO(), rpc.CommitmentFinalized)
  if err != nil {
    log.Fatal(err)
  }

  from := solana.MustPrivateKeyFromBase58("Tq5gFBU4QG6b6aUYAwi87CUx64iy5tZT1J6nuphN4FXov3UZahMYGSbxLGhb8a9UZ1VvxWB4NzDavSzTorqKCio")
  to := solana.MustPublicKeyFromBase58("BLrQPbKruZgFkNhpdGGrJcZdt1HnfrBLojLYYgnrwNrz")

  tx, err := solana.NewTransaction(
    []solana.Instruction{
      system.NewTransferInstruction(
        10000,
        from.PublicKey(),
        to,
      ).Build(),
    },
    block.Value.Blockhash,
    solana.TransactionPayer(from.PublicKey()),
  )
  if err != nil {
    log.Fatal(err)
  }

  if _, err = tx.Sign(
    func(key solana.PublicKey) *solana.PrivateKey {
      if from.PublicKey().Equals(key) {
        return &from
      }
      return nil
    },
  ); err != nil {
    log.Fatal(err)
  }

  txns = append(txns, tx)

  resp, err := client.BroadcastBundleWithConfirmation(txns, 100)
  if err != nil {
    log.Fatal(err)
  }

  log.Println(resp)
}

Subscribe to MemPool Transactions [Accounts]

	client, err := geyser_client.NewGeyserClient(context.Background(), rpcAddr, nil)
	if err != nil {
		log.Fatal(err)
	}
	
	// create block update sub
	sub, err := client.SubscribeBlockUpdates()
	if err != nil {
		log.Fatal(err)
	}
	// create chan to receive block updates
	ch := make(chan *proto.BlockUpdate)
	// feed the chan with block updates 
	client.OnBlockUpdates(context.Background(), sub, ch)
	
	// loop to read new block updates from chan
	for {
		block := <-ch
		log.Println(block)
	}
}
