BRIDGE BASICS

What is a Crypto Bridge?

A crypto bridge allows users to transfer digital assets between different blockchain networks safely and efficiently.

Bridges make the multi-chain ecosystem possible by connecting networks like Ethereum, Base, Arbitrum, Optimism, and many others.

WHY BRIDGES

Why Do We Need Bridges?

Different blockchains operate independently and cannot communicate with each other by default. Crypto bridges solve this problem by allowing assets to move between networks.

Bridges help users access lower fees, faster transactions, new DeFi opportunities, NFT marketplaces, and growing ecosystems like Base without being limited to a single blockchain.

HOW IT WORKS

How Do Crypto Bridges Work?

A crypto bridge transfers assets between blockchains by locking, minting, burning, or releasing tokens depending on the bridge's design.

When you bridge assets from Ethereum to Base, your tokens are securely processed so an equivalent amount becomes available on the destination network.

• Connect your wallet.
• Select the source blockchain.
• Select the destination blockchain.
• Enter the amount to transfer.
• Approve and confirm the transaction.
• Receive your assets on the destination network.

TYPES OF BRIDGES

Types of Crypto Bridges

Not all blockchain bridges work the same way. Different bridges are designed for different use cases and levels of decentralization.

• Native Bridges – Built and maintained by the blockchain itself.
• Third-Party Bridges – Developed by independent protocols to support multiple blockchains.
• Trusted Bridges – Managed by a centralized organization or validator.
• Trustless Bridges – Powered by smart contracts without relying on a central authority.

SECURITY

Bridge Safely

Crypto bridges are powerful tools, but using the wrong bridge or connecting to fake websites can put your assets at risk.

• Always use official bridge websites.
• Bookmark trusted bridge URLs.
• Double-check the destination network before confirming.
• Start with a small transfer when using a bridge for the first time.
• Never share your Secret Recovery Phrase.
