What is SolanaSDK?

SolanaSDK is a comprehensive .NET library designed to simplify interaction with the Solana blockchain. Built with performance, security, and developer experience in mind, it provides intuitive abstractions for secure wallet management, cryptographic operations, and blockchain interactions.

Key Innovation: Advanced SLIP-39 support enabling Shamir's Secret Sharing for enhanced wallet security and recovery flexibility.

Installation

Install via .NET CLI:

dotnet add package Solana.Sdk

Or via NuGet Package Manager Console:

Install-Package Solana.Sdk

Quick Start

Create a wallet and derive accounts:

using SolanaSDK;

// Create a new wallet with BIP39 mnemonic
var wallet = SWallet.Create();
var mnemonic = wallet.Mnemonic; // Save this securely!

// Derive an account from the wallet
var account = wallet.GetAccount(0);

// Sign a message
var message = System.Text.Encoding.UTF8.GetBytes("Hello, Solana!");
var signature = account.Sign(message);

// Verify the signature
var isValid = account.Verify(message, signature);

Key Classes

SWallet - Standard wallet for mnemonic-based (BIP39) or seed-based wallet management.

Slip39SWallet - SLIP-39 wallet with Shamir's Secret Sharing for enterprise-grade security.

SAccount - Represents a derived Solana keypair with signing and verification capabilities.

PublicKey & PrivateKey - Type-safe wrappers for Ed25519 cryptographic keys.

Use Cases

• Enterprise Wallet Infrastructure - Build secure multi-signature wallet systems
• DeFi Applications - Transaction signing and verification with multi-account management
• Staking & Treasury - Manage multiple wallets from a single seed
• Blockchain Services - High-throughput transaction processing with failover support

Requirements

• .NET 6.0 or higher
• C# 10.0 or higher
• Bifrost.Security (Ed25519 cryptography - automatically included)

Security Considerations

This library implements industry-standard cryptographic practices:

• Ed25519 signatures use proven algorithms
• BIP32 key derivation follows established standards
• SLIP-39 provides mathematically-proven secret sharing
• Type safety prevents common programming errors

Important Guidelines:

• Store keys in dedicated key storage systems
• Use hardware security modules for production
• Never commit secrets to version control
• Implement proper key rotation strategies
• Audit your implementation before production
