Multichain

The blockchain space has grown far beyond a single ecosystem. With dozens of Layer 1 blockchains (Ethereum, BNB Chain, Avalanche) and Layer 2 networks (Arbitrum, Optimism, zkSync), the need to move assets and data across chains has become vital. This is where Multichain comes in—a cross-chain infrastructure protocol that connects otherwise isolated blockchain networks.

In this article, you’ll learn what Multichain is, how it works, and why it plays such a crucial role in the modular, multichain future of Web3.

What is Multichain?

Multichain is a decentralized cross-chain router protocol that enables secure and efficient transfers of assets between different blockchains. Originally launched as Anyswap, Multichain has become a cornerstone of the Web3 interoperability layer, connecting over 80 public chains with a trust-minimized design.

It supports both EVM-compatible and non-EVM chains, allowing users and developers to move assets across networks like Ethereum, BNB Chain, Polygon, Arbitrum, Optimism, Fantom, Avalanche, and more.

Multichain is designed for speed, decentralization, and security—making it a preferred solution for individuals, DAOs, DeFi protocols, and institutional platforms.

How Does Multichain Work?

At the heart of Multichain is a cryptographic system called Secure Multi-Party Computation (SMPC). Here’s how it works:

• When a user initiates a bridge transaction, Multichain validators (called SMPC nodes) jointly manage private key shares.
  
  

• These validators verify the transaction across both chains and sign it cooperatively.
  
  

• No single node can control funds or act independently, making the system highly secure and trust-minimized.
  
  

This system removes the need for wrapped tokens or centralized custody—two common vulnerabilities in many bridge protocols.

Key Features of Multichain

• Supports 80+ Blockchains
  One of the most widely integrated bridge protocols in Web3.
  
  

• Fast and Efficient Transfers
  Bridge transactions often complete in under 5 minutes.
  
  

• No Native Token Required
  Multichain does not require a governance or utility token to function.
  
  

• Open Source and Audited
  Source code available on GitHub and continuously audited for security.
  
  

• Secure by Design
  Built on the SMPC cryptographic model—recommended by Binance Academy for its security benefits.
  
  

Why Does Multichain Matter?

With more dApps, tokens, and DeFi platforms expanding to multiple chains, interoperability has become essential. Without a reliable bridge, capital remains fragmented, and users face friction and high costs.

Multichain solves this problem by providing a universal bridge that connects major blockchains. This means:

• Developers can build multichain apps with shared state and liquidity
  
  

• Users can move assets between chains without high slippage or delay
  
  

• DAOs and treasuries can operate efficiently across ecosystems
  
  

• DeFi protocols can dynamically route liquidity where it's most needed
  
  

Use Cases

• Yield Optimization: Move assets to chains with better APY in real-time
  
  

• DAO Treasury Management: Deploy capital across chains without centralization risk
  
  

• NFT Portability: Bring NFTs across L1s and L2s for broader exposure
  
  

• Gaming & Metaverse: Enable cross-chain item and token utility
  
  

• Institutional Bridging: Integrate asset transfer within CeFi/DeFi workflows
  
  

Multichain in 2025

As of 2025, Multichain processes millions of transactions per year, moving billions in value. Its architecture has stood the test of time amid rising bridge exploits and regulatory scrutiny.

The team’s roadmap includes:

• ZK-proof integrations
  
  

• Cross-chain messaging
  
  

• Expanded support for modular rollups
  
  

• More developer-centric tooling
  
  

These additions will reinforce Multichain’s position as a core layer of Web3 infrastructure.

FAQ

What chains does Multichain support?
Multichain supports 80+ chains including Ethereum, Arbitrum, BNB Chain, Polygon, Avalanche, Optimism, and many others.

Is Multichain free to use?
A small transaction fee is charged for each bridge transfer, typically between 0.1% and 0.3%.

Is there a native token?
No. Multichain does not require a governance or utility token.

Is Multichain secure?
Yes. It uses SMPC cryptography and has been audited multiple times. The system is trust-minimized and decentralized.

Where can I explore the codebase?

How is it different from other bridges?
Unlike wrapped-token bridges or centralized custodians, Multichain uses SMPC and on-chain validators to maximize decentralization and minimize risk.

Conclusion

Multichain is not just a bridge—it's an essential infrastructure layer for the blockchain world of tomorrow. As ecosystems grow and diversify, Multichain helps unify them, unlocking composability, liquidity, and user mobility across networks.

Whether you're a user, builder, or investor, understanding and leveraging Multichain is crucial for navigating the multichain future of Web3.
