README

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.

Clients for Solana native programs, Solana Program Library (SPL), and Serum DEX are in development.

More contracts to come.

Contents

Features

  • Full JSON RPC API
  • Full WebSocket JSON streaming API
  • Wallet, account, and keys management
  • Clients for native programs
  • Clients for Solana Program Library
  • Client for Serum
  • More programs

Current development status

There is currently no stable release. The SDK is actively developed and latest is v0.4.0 which is an alpha release.

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

Requirements

  • Go 1.16 or later

Installation

⚠ solana-go works using SemVer but in 0 version, which means that the 'minor' will be changed when some broken changes are introduced into the application, and the 'patch' will be changed when a new feature with new changes is added or for bug fixing. As soon as v1.0.0 be released, solana-go will start to use SemVer as usual.

$ cd my-project
$ go get github.com/gagliardetto/solana-go@v0.4.0

Examples

Create account
package main

import (
  "context"
  "fmt"

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

func main() {
  // Create a new account:
  account := solana.NewAccount()
  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,
    "",
  )
  if err != nil {
    panic(err)
  }
  fmt.Println("airdrop transaction signature:", out)
}
Send Sol from one account to another
