Get the Dialect TypeScript SDK installed and configured in your environment. This guide covers installation, client setup, authentication, and environment configuration.

​
Installation

Install the core SDK and blockchain-specific packages for your needs: 
# Core SDK (required)
npm install @dialectlabs/sdk

# Blockchain SDK for Solana
npm install @dialectlabs/blockchain-sdk-solana

​
App Registration

Before using the SDK, you need to register your app. You can do this either:
  1. Via Dashboard: Follow our Dashboard registration guide to register
  2. Via SDK: Register programmatically using the SDK tab in the registration guide

​
Wallet Credentials Setup

If you registered via SDK: Your DIALECT_SDK_CREDENTIALS should already be set up from the registration process. If you registered via Dashboard: You need to extract the private key from the wallet you used to register and format it as DIALECT_SDK_CREDENTIALS. Your app is tied to the specific keypair used during registration:
  1. Export from your wallet app: Open Phantom, Solflare, etc. → Settings → Export Private Key → Copy the private key
  2. Convert to array format: Use a tool like this to convert base58 private key to JSON array format [170,23,...,300]
  3. Set in environment: Add the array format to your .env file as DIALECT_SDK_CREDENTIALS
You must use the same wallet that was used to register your app. The app registration is tied to that specific keypair and cannot be changed to a different wallet.
Secure Your Credentials: Keep your DIALECT_SDK_CREDENTIALS secure. This is your app’s private key and should never be exposed in client-side code or committed to version control.

​
SDK Client Setup

​
Basic SDK Initialization

import { Dialect, DialectCloudEnvironment, DialectSdk } from "@dialectlabs/sdk";
import {
  Solana,
  SolanaSdkFactory,
  NodeDialectSolanaWalletAdapter,
} from "@dialectlabs/blockchain-sdk-solana";

// Initialize SDK
const environment: DialectCloudEnvironment = "development";
const dialectSolanaSdk: DialectSdk<Solana> = Dialect.sdk(
  {
    environment,
  },
  SolanaSdkFactory.create({
    // IMPORTANT: must set environment variable DIALECT_SDK_CREDENTIALS
    // to your dapp's Solana messaging wallet keypair e.g. [170,23, . . . ,300]
    wallet: NodeDialectSolanaWalletAdapter.create(),
  })
);

// Load your dApp
const dapp = await dialectSolanaSdk.dapps.find();

if (!dapp) {
  throw new Error("Dapp not found. Please register your app first.");
}

console.log('✅ SDK initialized and dApp loaded!');

​
Environment-Specific Setup

// For production deployment, update the environment
const environment: DialectCloudEnvironment = "production"; // Change to "development" for testing

const dialectSolanaSdk = Dialect.sdk(
  {
    environment,
  },
  SolanaSdkFactory.create({
    // IMPORTANT: must set environment variable DIALECT_SDK_CREDENTIALS
    // to your dapp's Solana messaging wallet keypair e.g. [170,23, . . . ,300]
    wallet: NodeDialectSolanaWalletAdapter.create(),
  })
);

​
Troubleshooting

​
Common Issues

1. Invalid Credentials 
Error: Invalid wallet credentials
# Solution: Check your DIALECT_SDK_CREDENTIALS format
echo $DIALECT_SDK_CREDENTIALS | jq . # Should be valid JSON array
2. Dapp Not Found 
Error: Dapp not found
# Solution: Register your app first via dashboard or SDK
