Overview

Dynamic’s Node SDK provides comprehensive support for Solana (SVM) blockchain operations, including wallet creation, transaction signing, message signing, and key management. The SDK implements Multi-Party Computation (MPC) for enhanced security.

​
Key Features

  • MPC Wallet Creation: Create secure Solana wallets with threshold signature schemes
  • Transaction Signing: Sign Solana transactions without exposing private keys
  • Message Signing: Sign messages for authentication and data integrity
  • Key Import/Export: Import existing private keys and export wallet data
  • Multiple Security Models: Choose between different threshold signature schemes

​
Available Threshold Signature Schemes

  • TWO_OF_TWO: Maximum security - requires both server and Dynamic infrastructure
  • TWO_OF_THREE: Balanced security and availability - requires 2 out of 3 shares
  • THREE_OF_FIVE: High availability - requires 3 out of 5 shares

​
Quick Start

import { DynamicSvmWalletClient } from '@dynamic-labs-wallet/node-svm';
import { ThresholdSignatureScheme } from '@dynamic-labs-wallet/node';

const client = new DynamicSvmWalletClient({
  environmentId: process.env.DYNAMIC_ENVIRONMENT_ID!,
});

await client.authenticateApiToken(process.env.DYNAMIC_AUTH_TOKEN!);

// Create a new wallet
const wallet = await client.createWalletAccount({
  thresholdSignatureScheme: ThresholdSignatureScheme.TWO_OF_TWO,
  backUpToClientShareService: true,
});

console.log('Wallet created:', wallet.accountAddress);

Guides

​
Prerequisites

Before using the SVM SDK, ensure you have:
  1. Dynamic Project Setup: Set up your Dynamic project
  2. Environment Configuration: Configure your environment ID and auth token
  3. Solana Chain Enabled: Enable Solana chains in your Dynamic dashboard
  4. Dependencies Installed: Install required packages

​
Installation

bun add @dynamic-labs-wallet/node-svm @solana/web3.js @dynamic-labs-wallet/node

​
Environment Variables

DYNAMIC_AUTH_TOKEN=your_auth_token_here
DYNAMIC_ENVIRONMENT_ID=your_environment_id_here

​
Security Considerations

  • MPC Architecture: Private keys are never stored in plain text
  • Threshold Signing: Multiple parties must collaborate to sign transactions
  • Key Share Backup: Use backUpToClientShareService: true for secure storage
  • Password Protection: Implement strong passwords for additional security layers

​
Network Support

The SDK supports all Solana networks:
  • Mainnet: Production Solana network
  • Devnet: Development and testing network
  • Testnet: Testing network with test tokens

​
Error Handling

Always implement proper error handling: 
try {
  const result = await svmClient.someFunction(params);
  console.log('Operation successful:', result);
} catch (error) {
  console.error('Operation failed:', error instanceof Error ? error.message : String(error));
}
