Set up contract call policy

​

Create a contract-signing policy

1. Log into Cobo Portal.
2. Click > Transaction Policies in the main menu on the left-hand side.
3. Click Create Policy > Contract Call.

4. Enter a Policy Name. The name should not exceed 30 characters.
5. Select all the Applicable Wallets that are applicable to the policy you are about to create.
6. Select a Applicable Network that is applicable to the policy you are about to create.
7. Under If, click + Add condition to select a condition template. You can add one or more conditions to each policy. If multiple conditions are applied, the policy will be triggered only if the transaction satisfies all conditions. To learn more about conditions, see Select condition template
   • You have the option to skip setting any conditions and proceed directly to the next step. This means that any transaction signing associated with the applicable wallets will trigger this policy.
8. Select the action to be taken if the policy is triggered (i.e., Auto Approval, Auto Rejection, and Approval Quorum), then click Next. To learn more about approval actions, see Set approval action.
9. Review and confirm the policy, then click Next.
10. Adjust and review the priority of your policies. Transactions will be matched with policies in the list based on their priority order.
    • Once a higher-priority policy is triggered, subsequent policies will no longer be triggered.
    • By default, the newly created policy will be placed at the top of the policy list and highlighted. You can change the order by dragging and dropping.
11. Click Submit and, if required, complete the MFA verification.

• Frequency: You can define either the maximum amount applied per transaction or within a specified time window, denominated in hours.
