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](https://github.com/project-serum/anchor), you can use [anchor-go](https://github.com/gagliardetto/anchor-go) to generate Golang clients**

**If you're looking for a SERUM library, you can check out [gagliardetto/serum-go](https://github.com/gagliardetto/serum-go) ([./programs/serum](https://github.com/gagliardetto/solana-go/tree/main/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!

## Current development status

There is currently **no stable release**. The SDK is actively developed and latest is `v1.11.0` which is an `alpha` release.

The RPC and WS client implementation is based on [this RPC spec](https://github.com/solana-labs/solana/blob/c2435363f39723cef59b91322f3b6a815008af29/docs/src/developing/clients/jsonrpc-api.md).

## 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 1.18 or later

## Installation

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

## Pretty-Print transactions/instructions

![pretty-printed](https://user-images.githubusercontent.com/15271561/136708519-399c9498-3d20-48d6-89fa-bdf43aac6d83.png)

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

```go
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](#transfer-sol-from-one-wallet-to-another-wallet))

```go
// 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:

```go
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

```go
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:

```go
  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:

```go
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:

```go
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

```go
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

```go
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:

```go
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`:

```go
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)

```go
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/parse private and public keys

```go
{
  // 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
  }
}
```
