💡 TL;DR
Building custom vault policies with ZeroSig can help you secure your crypto assets by leveraging OTP-based 2FA, programmable on-chain rules, and panic freeze mechanisms.
Introduction to Custom Vault Policies 🔐
With the growing sophistication of cyber threats, securing your crypto assets is more crucial than ever. Custom vault policies are essential tools for developers looking to create robust security frameworks around their digital assets. By using ZeroSig's capabilities, you can implement enhanced security measures like OTP-based 2FA, programmable on-chain rules, and panic freeze options.
Understanding the Building Blocks 🏗️
OTP-based 2FA: The First Line of Defense
One-Time Password (OTP) based two-factor authentication (2FA) adds an essential layer of security. As a developer, you can integrate OTP-based 2FA to ensure that access to your vault requires not just a password, but also a dynamic code that changes with each login attempt.
Programmable On-Chain Rules: Customize Your Vault
Customizable on-chain rules offer flexibility in how transactions are processed. By using smart contracts, you can program conditions that must be met for a transaction to occur. This could include time-based locks, which we discuss in Implementing Timelocks in Your Smart Wallet.
Panic Freeze: An Emergency Brake 🚨
The panic freeze feature acts like an emergency brake for your assets. In case of suspicious activity, this mechanism allows you to freeze all transactions, providing time to assess and respond to potential threats. This was inspired by real-world hacks where the absence of such a feature led to significant losses.
Building Your Custom Vault Policy
- Define Your Security Needs: Determine what level of security is required based on the value and sensitivity of your assets.
- Implement OTP-based 2FA: Add an additional layer of security using dynamic, time-sensitive codes.
- Create On-Chain Rules: Use smart contracts to enforce custom rules and conditions for transactions.
- Set Up Panic Freeze: Prepare for emergencies with a mechanism to halt all transactions instantly.

Real-World Analogies: Fortifying Your Digital Fortress
Think of your vault policy as a medieval castle. The OTP-based 2FA serves as the moat, programmable on-chain rules are the castle walls, and the panic freeze is the drawbridge that can be raised at a moment's notice. These layers work together to protect against external threats.
