Configure governance policies and user roles

Set up governance policies and user roles

Configuring governance policies and user roles is essential for managing access control and security in your organization.

• Governance policies define approval rules for key operations (such as member deletion, organization freezing, and API key management), using mechanisms such as auto-approval, auto-rejection, and approval quorum. You can edit governance policies if the default ones don’t align with your organizational needs.
• User roles enable you to assign specific permissions to designated members within your organization. When you assign a role to a member, they can only perform actions allowed by that role. For instance, a member with the Viewer role can see wallet information but cannot withdraw tokens.

As an example, you could set up a governance policy requiring approval from at least two members with either Admin or Manager roles before deleting a member, as illustrated in the screenshot below.

Configure transaction policies

Configure transaction policies

Transaction policies are essential measures to secure your digital asset operations. When a transaction starts, it’s checked against your organization’s transaction policies in sequential order. If it matches a policy’s trigger condition, the specified action will be taken: auto-approve, auto-reject, or an approval quorum process.In this guide, we’ll create a policy that requires 2-of-3 Admin approval for large USDT withdrawals to non-trusted addresses. For other policy setups and advanced configurations, see Set up token transfer policy.

​

Prerequisites

• You have invited enough members to have at least 3 members in the organization and have assigned the Admin user role to at least 3 of them.

​

Configure a trusted receiving address list

First, create a list of trusted addresses that are pre-approved for withdrawals:

In our case, we will configure the system so that any large USDT withdrawals to addresses outside this trusted receiving address list will require multi-signature approval (2 out of 3 Admin signers).

1. Log in to Cobo Portal.
   • For testing, use the development environment.
   • For production, use the production environment.
2. Click > Transaction Policies.
3. Navigate to the Address Lists tab and click Create List.

4. Enter a name for your address list, then click Confirm.
5. Click your newly created address list, click Add Address, then enter your trusted addresses.
6. Click Submit and verify with your Google Authenticator code.

For more details on managing address lists, including batch uploads, see Address list.

​

Create the transaction policy

Now, let’s set up a policy with these security rules:

• Trigger: Withdrawals over 30,000,000 USDT to non-trusted addresses
• Action: Require approval from 2 out of 3 approvers with the Admin user role.

Follow these steps:

1. In Cobo Portal, go to > Transaction Policies.
2. Click Create Policy > Token Transfer.
3. Configure the settings as shown in the screenshot:

4. Click Next and follow the on-screen instructions to complete the policy setup.

Your policy is now active and will require 2-of-3 approval for any USDT withdrawal over 30,000,000 to non-trusted addresses. For more policy configurations and use cases, visit Set up token transfer policy.

​
