Overview

Spin up millions of secure, server-controlled wallets with battle-tested MPC infrastructure. Built for onchain automation, Dynamic Server Wallets let you trigger transactions, interact with contracts, and run complex flows—all without user involvement, and fully owned by your backend.

Setup (Node SDK)

Reference example: https://github.com/dynamic-labs/mpc-node-server-demo

1. Retrieve your auth token

   Navigate to the Dynamic Dashboard and create a new API token.

2. Install desired Node SDKs

   npm i @dynamic-labs-wallet/node-evm
   npm i @dynamic-labs-wallet/node-svm
   

3. Create client with authenticateApiToken

   Separate clients are needed for each chain.

   const BASE_API_URL = 'https://app.dynamicauth.com';
   const MPC_RELAY_URL = 'https://relay.dynamicauth.com';
   
   
   export const authenticatedEvmClient = async ({
         authToken,
         environmentId,
         baseApiUrl,
         baseMPCRelayApiUrl,
       }: {
         authToken: string;
         environmentId: string;
         baseApiUrl?: string;
         baseMPCRelayApiUrl?: string;
       }) => {
         const client = new DynamicEvmWalletClient({
           authToken,
           environmentId,
           baseApiUrl: BASE_API_URL,
           baseMPCRelayApiUrl: MPC_RELAY_URL,
         });
         await client.authenticateApiToken(authToken);
         return client;
     };
   

4. Access MPC functionality by creating a new wallet account

     const AUTH_TOKEN = 'your-auth-token';
     const ENVIRONMENT_ID = 'your-environment-id';
   
     const evmClient = await authenticatedEvmClient({
       authToken: AUTH_TOKEN,
       environmentId: ENVIRONMENT_ID,
     });
   
     const thresholdSignatureScheme = 'TWO_OF_TWO'; // or 'TWO_OF_THREE'
     const password = 'your-optional-password';
     const onError = (error: Error) => {
       // handle error
       console.error(error);
     };
   
     const {
       accountAddress,
       rawPublicKey,
       publicKeyHex,
       externalServerKeyShares,
         } = await evmClient.createWalletAccount({
           thresholdSignatureScheme,
           password,
           onError,
         });
   

   You can now use the accountAddress to sign messages, create transactions, and more. You can also back up your externalServerKeyShares to a secure location.

5. Example: Sign a message with the MPC wallet account

     const AUTH_TOKEN = 'your-auth-token';
     const ENVIRONMENT_ID = 'your-environment-id';
   
     const evmClient = await authenticatedEvmClient({
       authToken: AUTH_TOKEN,
       environmentId: ENVIRONMENT_ID,
     });
   
     const message = 'Hello, world!';
     const accountAddress = '0x1234567890123456789012345678901234567890';
     const password = 'your-optional-password';
   
     const serializedSignature = await evmClient.signMessage({
       message,
       accountAddress,
       password,
     });
