Get started with MPC Wallets

This guide provides a step-by-step walkthrough for setting up and using MPC Wallets on Cobo Portal. You’ll learn how to:

1. Set up your account and organization
2. Create vaults and wallets
3. Make deposits and withdrawals

​

Prerequisites

• Contact our sales team to acquire your account activation link.

• An iOS device to run Cobo Guard, our dedicated app for multi-factor authentication (MFA), operation approval, transaction signing, and key share management.

​

Set up accounts and organization

As the first admin of your organization, complete these initial steps to configure your account and organization:

​

Create an account

Use the activation link from our sales team to create your Cobo Portal account.

​

Set up Cobo Guard

   • For testing purposes, use the development environment.
   • For production, use the production environment.
2. Click Guide at the bottom left, and click Set up Cobo Guard.
3. Follow the instructions on the screen to install Cobo Guard on your iOS device and link your account with your Cobo Guard.

​

Configure governance policies and user roles

​

Invite members

1. Log in to Cobo Portal.
   • For testing purposes, use the development environment.

​

Set up an MPC vault

After setting up your account and organization, the next step is to configure an MPC vault. A default vault is automatically created for you. You need to complete the setup by creating a Main Group and generating key shares.

​

Create a Main Group

A set of key share holders is referred to as a holder group. The Main Group is the first holder group you create before using MPC Wallets.

The diagram below illustrates a Main Group with two key share holders. Cobo holds one key share, while your organization holds the other.

Follow the instructions below to create a Main Group in Cobo Portal:

1. Log in to Cobo Portal.

   • For testing purposes, use the development environment.
   • For production, use the production environment.

2. Click > MPC Wallets.

3. Click Create Main Group.

4. In the Create Main Group dialog box, navigate to the Key Share Holder 2 section, and configure the holder. For detailed information about co-signer types and their setup, see Co-Signer Type.

   • To use a mobile co-signer, select a holder from the pull-down list. The TSS Node ID field will be filled in automatically. Click Confirm.

     For quick testing, you can select yourself as a holder. However, for production use, refer to our Security best practices for guidance on selecting appropriate holders.

   • To use a server co-signer, enter a holder name, fill in the TSS Node ID, and then click Confirm.

5. Confirm in your Cobo Guard app that you initiated this request.

​

Generate key shares

To finalize the vault setup, the next crucial step is generating key shares on your co-signer. This process varies depending on your co-signer type:

• For mobile co-signers:

  • Wait for the 1 key share needs to be generated banner to appear on Cobo Guard (this may take a few seconds).
  • Tap the banner to open the key generation interface.
  • Follow the on-screen instructions to complete the key share generation process.
  • We recommend backing up your key shares at this point for added security. However, you can also choose to complete this step later after finishing the guide.

• For server co-signers:

  • Ensure the TSS Node server is brought online within 24 hours. The key share generation process initiates automatically when the server comes online.
  • If a TSS Node callback server is configured, the generation process will only start after approval from the callback server.

Once the key generation process is completed, the holder group status will become Active on Cobo Portal. You might need to refresh the Cobo Portal page to see the updated result.

​

Create a wallet and transfer tokens

​

Create a wallet

After successful key generation, a default wallet is automatically created for your vault. You can create additional wallets by following the steps below:

1. Log in to Cobo Portal.
   • For testing purposes, use the development environment.
   • For production, use the production environment.
2. Click > MPC Wallets.
3. Click Create Wallet. In the dialog box:
   • Enter a unique name for your wallet.
   • If you need to automatically consolidate funds from multiple addresses, enable Auto-Sweep. If you’re unsure, you can leave it disabled for now and enable it later if needed.
4. Click Create.
5. From the wallet list, select your newly created wallet to view its details.

​

Make a deposit

To make a deposit, you should first generate a deposit address for your wallet:

1. Navigate to the Addresses tab, and then click Add Address.
2. Select a network, and then click Create.
3. Navigate to the address you just created and click to display the address.
4. Proceed to your preferred external wallet to initiate the transfer to the deposit address.

​

Configure transaction policies

​

Make a withdrawal

Follow the steps below to withdraw tokens from your wallet.

1. Log in to Cobo Portal.

   • For testing purposes, use the development environment.
   • For production, use the production environment.

2. Click in the main menu on the left hand side.

3. In the Transfer dialog box, fill in the required information, and then click Submit.
4. Double confirm the withdrawal on Cobo Guard.
5. One of your co-signers will be automatically selected to sign the transaction based on their online status and other criteria. Ensure that at least one co-signer is ready to complete the signing process.

After you sign the transaction, Cobo creates and broadcasts it to the network. The token transfer may take some time to complete, depending on network conditions.

​

View transaction details and status

After making a transfer to or from your Asset Wallets, you can view its transaction status in > Transaction History.

​

Integrate using the WaaS API

To create wallets and transfer tokens programmatically, you can utilize our WaaS API. Follow these steps to integrate wallet functionality using the API:

1. Start with Sending your first request. This guide covers API key registration, authentication, and SDK usage.
2. Proceed to Integrate MPC Wallets (Organization-Controlled) for detailed instructions on creating wallets and managing token transactions.
