Secure Your Digital Assets with Next-Gen Blockchain Security

Enterprise-Grade Protection for Your Digital Assets

Chain-Fi provides cutting-edge vault security combined with decentralized two-factor authentication (2FA) to shield your blockchain assets from sophisticated attacks.

  • Multi-signature vault protection
  • ChainGuard 2FA security
  • Cross-chain asset management

Our advanced security infrastructure protects Ethereum, ERC-20 tokens, NFTs, and all digital holdings, preventing vulnerabilities that have already resulted in over $3 billion in losses.

Chain-Fi is currently integrated with these blockchain networks:

Guardian Signature Security
Cross-Chain Protection
Regulatory Compliant

Security in Three Steps

Chain-Fi provides a streamlined, secure process to protect your digital assets. Through a user-friendly combination of mobile verification, decentralized 2FA via ChainGuard, and intuitive vault creation, your crypto holdings remain safeguarded at every transaction step. Below, discover exactly how our advanced security architecture ensures ultimate protection for both individual and enterprise-level digital asset management

The following section contains three sequential steps to secure your digital assets with Chain-Fi. Each step has two buttons: a main action button and an "Info" button. We recommend clicking the "Info" button first to learn detailed information about each step before proceeding. The Info dialogs contain comprehensive explanations and direct action buttons to guide you through the process. The three steps are: Step 1 - Install ChainGuard mobile app, Step 2 - Create Your Vault, and Step 3 - Transfer Assets. You can navigate through these steps in order or access detailed information about any step using the Info buttons.
1

Install ChainGuard

Download our mobile app to enable decentralized 2FA protection across all your assets.

2

Create Your Vault

Connect your wallet and deploy your secure vault with our guided setup process.

3

Transfer Assets

Move your digital assets into your vault and experience true security for the first time.

Dual-Device Security Model

ChainFi's innovative security approach uses two separate devices to create an impenetrable barrier against attacks. Even if one device is compromised, your assets remain secure.

Separation of Powers

Transaction initiation and approval happen on different devices

On-Chain Verification

All security happens on-chain with cryptographic verification

Recovery Protection

Decentralized Recovery options if device access is lost through multi address protection (the 3 addresses system where you can change one when you have 2 of them)

Three-Address Security Protocol

Our revolutionary security system uses three separate addresses to create an impenetrable defense mechanism. Your Primary Address is the only one that can interact with the Vault contract on-chain, but every action requires an off-chain signature from your 2FA Address in the ChainGuard app. The Secondary Address provides recovery protection - any two addresses working together can reset the third after a security cooldown, ensuring you never lose access while maintaining maximum security against sophisticated attacks.

The following section contains a visual layout of the three-address security protocol. Start by selecting the Primary Address to begin the guided tour. You will be taken through each component in sequence: Primary Address, then Secondary Address, then 2FA Address, then Secure Vault, and back to Primary Address in a circular flow. Use the right arrow key or the navigation button to advance to the next section.

Recovery Protection System

Any two addresses can recover the third after a security cooldown period. This creates a robust security system that prevents single points of failure while maintaining complete control over your assets.
