Solana SDK library for Go

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

Features

Current development status

There is currently no stable release. The SDK is actively developed and latest is v1.16.0 which is an alpha release.

The RPC and WS client implementation is based on the Solana RPC API documentation.

Note

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

Requirements

Go 1.24 or later

Installation

$ cd my-project
$ go get github.com/gagliardetto/solana-go@v1.16.0

Pretty-Print transactions/instructions

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:

package main

import (
	"context"
	"fmt"
	"time"

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

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(
		context.Background(),
		solana.MustSignatureFromBase58("24jRjMP3medE9iMqVSPRbkwfe9GdPmLfeftKPuwRHZdYTZJ6UyzNMGGKo4BHrTu2zVj4CgFF3CEuzS79QXUo2CMC"),
		&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())
}

Parse/decode an instruction from a transaction

package main

import (
  "context"
  "encoding/base64"
  "os"
  "reflect"

  "github.com/davecgh/go-spew/spew"
  bin "github.com/gagliardetto/binary"
  "github.com/gagliardetto/solana-go"
  "github.com/gagliardetto/solana-go/programs/system"
  "github.com/gagliardetto/solana-go/rpc"
  "github.com/gagliardetto/solana-go/text"
)

func main() {
  exampleFromGetTransaction()
}

func exampleFromBase64() {
  encoded := "AfjEs3XhTc3hrxEvlnMPkm/cocvAUbFNbCl00qKnrFue6J53AhEqIFmcJJlJW3EDP5RmcMz+cNTTcZHW/WJYwAcBAAEDO8hh4VddzfcO5jbCt95jryl6y8ff65UcgukHNLWH+UQGgxCGGpgyfQVQV02EQYqm4QwzUt2qf9f1gVLM7rI4hwAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA6ANIF55zOZWROWRkeh+lExxZBnKFqbvIxZDLE7EijjoBAgIAAQwCAAAAOTAAAAAAAAA="

  data, err := base64.StdEncoding.DecodeString(encoded)
  if err != nil {
    panic(err)
  }

  // parse transaction:
  tx, err := solana.TransactionFromDecoder(bin.NewBinDecoder(data))
  if err != nil {
    panic(err)
  }

  decodeSystemTransfer(tx)
}

func exampleFromGetTransaction() {
  endpoint := rpc.TestNet_RPC
  client := rpc.New(endpoint)

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

    tx, err := solana.TransactionFromDecoder(bin.NewBinDecoder(out.Transaction.GetBinary()))
    if err != nil {
      panic(err)
    }

    decodeSystemTransfer(tx)
  }
}

func decodeSystemTransfer(tx *solana.Transaction) {
  spew.Dump(tx)

  // Get (for example) the first instruction of this transaction
  // which we know is a `system` program instruction:
  i0 := tx.Message.Instructions[0]

  // Find the program address of this instruction:
  progKey, err := tx.ResolveProgramIDIndex(i0.ProgramIDIndex)
  if err != nil {
    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
  // what program the instruction is for / you don't have a parser.
  inst, err := system.DecodeInstruction(accounts, i0.Data)
  if err != nil {
    panic(err)
  }

  // inst.Impl contains the specific instruction type (in this case, `inst.Impl` is a `*system.Transfer`)
  spew.Dump(inst)
  if _, ok := inst.Impl.(*system.Transfer); !ok {
    panic("the instruction is not a *system.Transfer")
  }

  // OR
  {
    // There is a more general instruction decoder: `solana.DecodeInstruction`.
    // But before you can use `solana.DecodeInstruction`,
    // you must register a decoder for each program ID beforehand
    // by using `solana.RegisterInstructionDecoder` (all solana-go program clients do it automatically with the default program IDs).
    decodedInstruction, err := solana.DecodeInstruction(
      progKey,
      accounts,
      i0.Data,
    )
    if err != nil {
      panic(err)
    }
    // The returned `decodedInstruction` is the decoded instruction.
    spew.Dump(decodedInstruction)

    // decodedInstruction == inst
    if !reflect.DeepEqual(inst, decodedInstruction) {
      panic("they are NOT equal (this would never happen)")
    }

    // To register other (not yet registered decoders), you can add them with
    // `solana.RegisterInstructionDecoder` function.
  }

  {
    // pretty-print whole transaction:
    _, err := tx.EncodeTree(text.NewTreeEncoder(os.Stdout, text.Bold("TEST TRANSACTION")))
    if err != nil {
      panic(err)
    }
  }
}

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)
}

Examples

Create account (wallet)

package main

import (
  "context"
  "fmt"

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

func main() {
  // Create a new account:
  account := solana.NewWallet()
  fmt.Println("account private key:", account.PrivateKey)
  fmt.Println("account public key:", account.PublicKey())

  // Create a new RPC client:
  client := rpc.New(rpc.TestNet_RPC)

  // Airdrop 1 SOL to the new account:
  out, err := client.RequestAirdrop(
    context.TODO(),
    account.PublicKey(),
    solana.LAMPORTS_PER_SOL*1,
    rpc.CommitmentFinalized,
  )
  if err != nil {
    panic(err)
  }
  fmt.Println("airdrop transaction signature:", out)
}

{
  // Load private key from a json file generated with
  // $ solana-keygen new --outfile=standard.solana-keygen.json
  privateKey, err := solana.PrivateKeyFromSolanaKeygenFile("/path/to/standard.solana-keygen.json")
  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())
}

{
  // Load private key from base58:
  {
    privateKey, err := solana.PrivateKeyFromBase58("66cDvko73yAf8LYvFMM3r8vF5vJtkk7JKMgEKwkmBC86oHdq41C7i1a2vS3zE1yCcdLLk6VUatUb32ZzVjSBXtRs")
    if err != nil {
      panic(err)
    }
    fmt.Println("private key:", privateKey.String())
    fmt.Println("public key:", privateKey.PublicKey().String())
  }
  // OR:
  {
    privateKey := solana.MustPrivateKeyFromBase58("66cDvko73yAf8LYvFMM3r8vF5vJtkk7JKMgEKwkmBC86oHdq41C7i1a2vS3zE1yCcdLLk6VUatUb32ZzVjSBXtRs")
    _ = privateKey
  }
}

{
  // Generate a new key pair:
  {
    privateKey, err := solana.NewRandomPrivateKey()
    if err != nil {
      panic(err)
    }
    _ = privateKey
  }
  {
    { // Generate a new private key (a Wallet struct is just a wrapper around a private key)
      account := solana.NewWallet()
      _ = account
    }
  }
}

{
  // Parse a public key from a base58 string:

    publicKey, err := solana.PublicKeyFromBase58("F8UvVsKnzWyp2nF8aDcqvQ2GVcRpqT91WDsAtvBKCMt9")
    if err != nil {
      panic(err)
    }
    _ = publicKey
  }
  // OR:

    publicKey := solana.MustPublicKeyFromBase58("F8UvVsKnzWyp2nF8aDcqvQ2GVcRpqT91WDsAtvBKCMt9")
    _ = publicKey
