Solana SDK library for Go

GoDoc GitHub tag (latest SemVer pre-release) Build Status TODOs Go Report Card

Go library to interface with Solana JSON RPC and WebSocket interfaces.

More contracts to come.

If you're using/developing Solana programs written in Anchor Framework, you can use anchor-go to generate Golang clients

If you're looking for a SERUM library, you can check out gagliardetto/serum-go (./programs/serum is deprecated.)

Future Development

solana-go is exclusively supported by my own time (which is money).

If my work has been useful in building your for-profit services/infra/bots/etc., consider donating at 8tTwBazKr2ST1b2kNrM7JMXwixRTvZicn7eRBihThymm (solana) to support future development.

Thanks!

  • solana-go is in active development, so all APIs are subject to change.
  • This code is unaudited. Use at your own risk.

Requirements

  • Go 1.18 or later

Installation

$ cd my-project
$ go get github.com/gagliardetto/solana-go@v1.11.0

Pretty-Print transactions/instructions

pretty-printed

Instructions can be pretty-printed with the String() method on a Transaction:

tx, err := solana.NewTransaction(
  []solana.Instruction{
    system.NewTransferInstruction(
      amount,
      accountFrom.PublicKey(),
      accountTo,
    ).Build(),
  },
  recent.Value.Blockhash,
  solana.TransactionPayer(accountFrom.PublicKey()),
)

...

// Pretty print the transaction:
fmt.Println(tx.String())
// OR you can choose a destination and a title:
// tx.EncodeTree(text.NewTreeEncoder(os.Stdout, "Transfer SOL"))

SendAndConfirmTransaction

You can wait for a transaction confirmation using the github.com/gagliardetto/solana-go/rpc/sendAndConfirmTransaction package tools (for a complete example: see here)

// Send transaction, and wait for confirmation:
sig, err := confirm.SendAndConfirmTransaction(
  context.TODO(),
  rpcClient,
  wsClient,
  tx,
)
if err != nil {
  panic(err)
}
spew.Dump(sig)

The above command will send the transaction, and wait for its confirmation.

Address Lookup Tables

Resolve lookups for a transaction:

func main() {
	cluster := rpc.MainNetBeta

	rpcClient := rpc.NewWithCustomRPCClient(rpc.NewWithLimiter(
		cluster.RPC,
		rate.Every(time.Second), // time frame
		5,                       // limit of requests per time frame
	))

	version := uint64(0)
	tx, err := rpcClient.GetTransaction(

		&rpc.GetTransactionOpts{
			MaxSupportedTransactionVersion: &version,
			Encoding:                       solana.EncodingBase64,
		},
	)
	if err != nil {
		panic(err)
	}
	parsed, err := tx.Transaction.GetTransaction()
	if err != nil {
		panic(err)
	}
	processTransactionWithAddressLookups(*parsed, rpcClient)
}

func processTransactionWithAddressLookups(txx solana.Transaction, rpcClient *rpc.Client) {
	if !txx.Message.IsVersioned() {
		fmt.Println("tx is not versioned; only versioned transactions can contain lookups")
		return
	}
	tblKeys := txx.Message.GetAddressTableLookups().GetTableIDs()
	if len(tblKeys) == 0 {
		fmt.Println("no lookup tables in versioned transaction")
		return
	}
	numLookups := txx.Message.GetAddressTableLookups().NumLookups()
	if numLookups == 0 {
		fmt.Println("no lookups in versioned transaction")
		return
	}
	fmt.Println("num lookups:", numLookups)
	fmt.Println("num tbl keys:", len(tblKeys))
	resolutions := make(map[solana.PublicKey]solana.PublicKeySlice)
	for _, key := range tblKeys {
		fmt.Println("Getting table", key)

		info, err := rpcClient.GetAccountInfo(
			context.Background(),
			key,
		)
		if err != nil {
			panic(err)
		}
		fmt.Println("got table "+key.String())

		tableContent, err := lookup.DecodeAddressLookupTableState(info.GetBinary())
		if err != nil {
			panic(err)
		}

		fmt.Println("table content:", spew.Sdump(tableContent))
		fmt.Println("isActive", tableContent.IsActive())

		resolutions[key] = tableContent.Addresses
	}

	err := txx.Message.SetAddressTables(resolutions)
	if err != nil {
		panic(err)
	}

	err = txx.Message.ResolveLookups()
	if err != nil {
		panic(err)
	}
	fmt.Println(txx.String())
}

  client := rpc.New(endpoint)

  txSig := solana.MustSignatureFromBase58("3hZorctJtD3QLCRV3zF6JM6FDbFR5kAvsuKEG1RH9rWdz8YgnDzAvMWZFjdJgoL8KSNzZnx7aiExm1JEMC8KHfyy")
  {
    out, err := client.GetTransaction(
      context.TODO(),
      txSig,
      &rpc.GetTransactionOpts{
        Encoding: solana.EncodingBase64,

    panic(err)
  }

  // Find the accounts of this instruction:
  accounts, err := i0.ResolveInstructionAccounts(&tx.Message)
  if err != nil {
    panic(err)
  }

  // Feed the accounts and data to the system program parser
  // OR see below for alternative parsing when you DON'T know

  }
}

Borsh encoding/decoding

You can use the github.com/gagliardetto/binary package for encoding/decoding borsh-encoded data:

Decoder:

  resp, err := client.GetAccountInfo(
    context.TODO(),
    pubKey,
  )
  if err != nil {
    panic(err)
  }

  borshDec := bin.NewBorshDecoder(resp.GetBinary())
  var meta token_metadata.Metadata
  err = borshDec.Decode(&meta)
  if err != nil {
    panic(err)
  }

Encoder:

buf := new(bytes.Buffer)
borshEncoder := bin.NewBorshEncoder(buf)
err := borshEncoder.Encode(meta)
if err != nil {
  panic(err)
}
// fmt.Print(buf.Bytes())

ZSTD account data encoding

You can request account data to be encoded with base64+zstd in the Encoding parameter:

resp, err := client.GetAccountInfoWithOpts(
  context.TODO(),
  pubKey,
  &rpc.GetAccountInfoOpts{
    Encoding:   solana.EncodingBase64Zstd,
    Commitment: rpc.CommitmentFinalized,
  },
)
if err != nil {
  panic(err)
}
spew.Dump(resp)

var mint token.Mint
err = bin.NewDecoder(resp.GetBinary()).Decode(&mint)
if err != nil {
  panic(err)
}
spew.Dump(mint)

Working with rate-limited RPC providers

package main

import (
  "context"

  "golang.org/x/time/rate"
  "github.com/davecgh/go-spew/spew"
  "github.com/gagliardetto/solana-go/rpc"
)

func main() {
  cluster := rpc.MainNetBeta
  client := rpc.NewWithCustomRPCClient(rpc.NewWithLimiter(
		cluster.RPC,
		rate.Every(time.Second), // time frame
		5,                       // limit of requests per time frame
	))

  out, err := client.GetVersion(
    context.TODO(),
  )
  if err != nil {
    panic(err)
  }
  spew.Dump(out)
}

Custom Headers for authenticating with RPC providers

package main

import (
  "context"

  "golang.org/x/time/rate"
  "github.com/davecgh/go-spew/spew"
  "github.com/gagliardetto/solana-go/rpc"
)

func main() {
  cluster := rpc.MainNetBeta
  client := rpc.NewWithHeaders(
    cluster.RPC,
    map[string]string{
      "x-api-key": "...",
    },
  )

  out, err := client.GetVersion(
    context.TODO(),
  )
  if err != nil {
    panic(err)
  }
  spew.Dump(out)
}

The data will AUTOMATICALLY get decoded and returned (the right decoder will be used) when you call the resp.GetBinary() method.

Timeouts and Custom HTTP Clients

You can use a timeout context:

ctx, cancel := context.WithTimeout(context.Background(), time.Second*3)
defer cancel()
acc, err := rpcClient.GetAccountInfoWithOpts(
  ctx,
  accountID,
  &rpc.GetAccountInfoOpts{
    Commitment: rpc.CommitmentProcessed,
  },
)

Or you can initialize the RPC client using a custom HTTP client using rpc.NewWithCustomRPCClient:

import (
  "net"
  "net/http"
  "time"

  "github.com/gagliardetto/solana-go/rpc"
  "github.com/gagliardetto/solana-go/rpc/jsonrpc"
)

func NewHTTPTransport(
  timeout time.Duration,
  maxIdleConnsPerHost int,
  keepAlive time.Duration,
) *http.Transport {
  return &http.Transport{
    IdleConnTimeout:     timeout,
    MaxIdleConnsPerHost: maxIdleConnsPerHost,
    Proxy:               http.ProxyFromEnvironment,
    Dial: (&net.Dialer{
      Timeout:   timeout,
      KeepAlive: keepAlive,
    }).Dial,
  }
}

// NewHTTP returns a new Client from the provided config.
func NewHTTP(
  timeout time.Duration,
  maxIdleConnsPerHost int,
  keepAlive time.Duration,
) *http.Client {
  tr := NewHTTPTransport(
    timeout,
    maxIdleConnsPerHost,
    keepAlive,
  )

  return &http.Client{
    Timeout:   timeout,
    Transport: tr,
  }
}

// NewRPC creates a new Solana JSON RPC client.
func NewRPC(rpcEndpoint string) *rpc.Client {
  var (
    defaultMaxIdleConnsPerHost = 10
    defaultTimeout             = 25 * time.Second
    defaultKeepAlive           = 180 * time.Second
  )
  opts := &jsonrpc.RPCClientOpts{
    HTTPClient: NewHTTP(
      defaultTimeout,
      defaultMaxIdleConnsPerHost,
      defaultKeepAlive,
    ),
  }
  rpcClient := jsonrpc.NewClientWithOpts(rpcEndpoint, opts)
  return rpc.NewWithCustomRPCClient(rpcClient)
}

  if err != nil {
    panic(err)
  }
  fmt.Println("private key:", privateKey.String())
  // To get the public key, you need to call the `PublicKey()` method:
  publicKey := privateKey.PublicKey()
  // To get the base58 string of a public key, you can call the `String()` method:
  fmt.Println("public key:", publicKey.String())
}
