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 DkP56dVfmTTN58oy6hDpRLtw4RMEFMmEWs8umN3Kg8vp

Thanks!

Current development status

There is currently no stable release. The SDK is actively developed and latest is v1.5.0 which is an alpha release.

The RPC and WS client implementation is based on this RPC spec.

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 1.16 or later

Installation

$ cd my-project
$ go get github.com/gagliardetto/[email protected]

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.

  // parse transaction:

  if err != nil {
    panic(err)

  decodeSystemTransfer(tx)
}

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

  txSig := solana.MustSignatureFromBase58("3pByJJ2ff7EQANKd2bgetmnYQxknk3QUib1xLMnrg6aCvg5hS78peaGMoceC9AFckomqrsgo38DpzrG2LPW9zj3g")
  {
    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 {

    }

    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 if err != nil {
    panic(err)
  }

  // FInd the accounts of this instruction:
  accounts := i0.ResolveInstructionAccounts(&tx.Message)

  // 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)

    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)")

  }

  {

    if err != nil {

  }
}

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.Value.Data.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.Value.Data.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.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.Value.Data.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)
}
