Understanding Bridges: How to Move Assets Between Blockchains

Connecting Blockchain Islands

Imagine each blockchain network (such as Ethereum, Polygon, or Arbitrum) is an independent island with its own currency and system. To move value from one island to another, you need a “Bridge”.

Why Do You Need to Use a Bridge?

1. Low Transaction Costs: Some blockchains (Layer 2) offer gas fees much cheaper than the Ethereum Mainnet.
2. Access to DeFi Opportunities: Certain yield opportunities may only be available on specific networks.
3. Time Efficiency: Bridges allow for relatively fast asset transfers compared to traditional exchange withdrawal methods.

How Do Bridges Work?

Most bridges use a Lock & Mint mechanism:

• Your assets are locked (lock) on the source network.
• The bridge issues a representation of the same asset (wrap) on the target network.

Security is the Priority

Bridges are one of the primary targets for cyberattacks in the crypto world. Whale’X only recommends using official bridges (Canonical Bridges) or protocols that have passed rigorous security audits. In the VIP Circle, we guide you in choosing the safest bridge route for your family assets.
