Delve Deeper into the Policy Engine: How to Optimize Your Self-Custody Wallet Transaction Approval Process

In today’s digital and decentralized financial environment, the security and efficiency of self-custody wallets are core challenges for business operations. As transaction volumes increase and business processes become more complex, how to ensure transaction security while efficiently completing approvals has become an urgent issue to address. Today, we will delve into Safeheron’s Policy Engine—a powerful tool that can optimize the transaction approval process of self-custody wallets through flexible rule settings and automated execution. It not only supports customized strategies for various withdrawal types but also provides centralized log monitoring functions to ensure the transparency of fund flows and compliance of operations, offering comprehensive risk control and security for enterprises in the storage, management, and transfer of digital assets.

What is the Policy Engine?

The Policy Engine is an intelligent rule management system that automates various business processes through predefined rules and logic. In the context of self-custody wallets, the Policy Engine is mainly used to control transaction approval processes, helping institutions or individual users achieve efficient and secure transaction management. Safeheron’s Policy Engine has been upgraded to an advanced version, capable of centrally managing strategies that fit different scenarios. Users can configure these strategies through the Safeheron Web Console to optimize the entire approval system.

Why Do We Need a Policy Engine?

1. Enhance Efficiency

Traditional transaction approval processes often rely on manual operations, which are not only time-consuming and labor-intensive but also prone to errors. The Policy Engine automates the approval process, significantly increasing transaction processing speed, reducing human intervention, and improving overall efficiency.

2. Enhance Security

In the financial sector, transaction security is crucial. The Policy Engine can set complex approval rules and restrictions to ensure that only transactions meeting specific conditions can be approved, effectively preventing fraud and malicious activities.

3. Flexibility and Scalability

Business needs are constantly changing. The Policy Engine allows users to adjust rules at any time without the need to rewrite code or redeploy systems. This flexibility enables users to quickly adapt to market changes and business adjustments.

How to Configure Transfer Policies?

1. Log in to the Web Console

First, users need to log in to the Safeheron Web Console, navigate to "Management" -> "Policy Engine" -> "Transfer Policies" page, and start adding policies.

2. Set Policy Name

Give your policy a clear and descriptive name for easy management and identification later on.

3. Select Initiator

You can choose to allow all users to initiate transactions or restrict it to specific API Keys or team members with transaction initiation permissions. If you select all API Keys or all team members, newly added members with transaction initiation permissions will automatically be included in the list of initiators for this policy.

4. Select Source Account (From)

You can choose to allow all wallets to initiate transactions or specify certain wallets. This step can be flexibly configured according to your business needs.

5. Select Destination Account (To)

You can choose to allow transactions to any address, unfamiliar addresses, or specific destinations generated or configured within Safeheron. This helps further refine the scope and security of transactions.

6. Select Currency

Transfer policies can apply to one or multiple currencies across a single or multiple networks. You can select the currencies based on your actual needs and set corresponding restrictions.

7. Set Restrictions

This is the core part of policy configuration. You can set different limit ranges based on transaction value or currency quantity, whether for single transactions or cumulative transactions. Up to 10 non-overlapping ranges can be configured. In this way, one policy can meet the various needs of an entire business line.

8. Configure Execution Actions

Based on different restrictions, you can configure corresponding execution actions, currently supporting two types:

• Approval: Select configured approval nodes to form an approval process for transactions that trigger the restrictions.
• Interception: When a transaction triggers the restrictions, it will be directly intercepted.

Policy Sorting and Approval

1. Policy Sorting

Transfer policies are a key link in protecting assets. Each team can create multiple transfer policies and adjust their order to set their priority. Once a high-priority policy is triggered, no other policies with lower priority will be triggered.

2. Editing and Approving Policies

The Policy Engine treats all transfer policies as an interconnected whole. Therefore, the policy approval process covers all transfer policies. You can add or edit transfer policies in the Web Console. After editing, click "Submit for Approval" to submit all policies for decision-making approval.

After submitting the policy for approval, the team administrator will receive an approval task in the Safeheron App and a notification in the Web Console. The administrator can view the updated details of the transfer policies on the policy change page in the Web Console. If the changes are approved, the administrator can use the Safeheron App to scan the code for approval.

Future Development Directions of the Policy Engine

With the continuous development of blockchain technology and fintech, the functions of the Policy Engine will also continue to expand and optimize. In the future, the Policy Engine may integrate more artificial intelligence and machine learning technologies to achieve smarter rule generation and dynamic adjustments. At the same time, with the increasing popularity of cross-chain transactions and multi-chain wallets, the Policy Engine will also support more complex multi-chain scenarios, providing users with a more comprehensive and efficient transaction management solution.
