In the rapidly evolving world of decentralized finance (DeFi), the ability to move digital assets freely across blockchains is no longer a luxury—it's a necessity. The Cross-Chain Router by Multichain redefines interoperability by enabling seamless transfers of any asset between multiple blockchains, whether those assets are natively issued or created through Multichain’s bridge infrastructure.
This advanced routing system ensures that users can transfer tokens across chains with minimal friction, optimized liquidity utilization, and enhanced security. By leveraging smart contract automation and a distributed network of nodes, the Cross-Chain Router supports three distinct transfer models: native assets, bridged assets, and hybrid configurations.
How the Cross-Chain Router Works
At its core, the Cross-Chain Router acts as an intelligent traffic controller for blockchain assets. It dynamically routes token transfers based on the type of asset and the availability of liquidity across chains. This flexibility allows developers and users alike to interact with multi-chain ecosystems without being locked into a single network.
The system operates using a combination of liquidity pools, synthetic representations (anyTokens), and SMPC (Secure Multi-Party Computation) node networks to validate and execute cross-chain transactions securely and efficiently.

Transfer Type (a): Native Assets
When a token already exists on a target blockchain—such as USDC on Ethereum or DAI on Arbitrum—it is considered a native asset. In such cases, Multichain cannot mint additional supply, so it relies on liquidity pools to facilitate transfers.
Here’s how it works:
- Users deposit their native tokens (e.g., XYZ) into a pool on Chain A.
- An equivalent amount of anyXYZ tokens are minted on Chain A as a temporary representation.
- The SMPC network detects the deposit and triggers the minting of anyXYZ on Chain B, while burning the original anyXYZ on Chain A.
- If sufficient XYZ tokens exist in the pool on Chain B, they are sent directly to the user’s wallet, and the anyXYZ are burned.
- If liquidity is insufficient, the user receives anyXYZ tokens representing their claim (referred to as “Your Pool Share”) and must later redeem them when liquidity is replenished.
This mechanism ensures that the total circulating supply of XYZ across all chains remains constant—unless new tokens are intentionally added or removed from the pools.
Note: Liquidity rebalances naturally when users route assets in the opposite direction or when project teams inject additional tokens into under-resourced pools.
While effective, this model introduces dependency on pool depth. However, the use of anyTokens mitigates downtime by allowing users to claim assets later, preserving transaction finality even during low-liquidity periods.
Transfer Type (b): Bridged Assets
For assets built using AnyswapV5ERC20.sol or its variants—commonly referred to as bridged assets—the Cross-Chain Router eliminates reliance on liquidity pools altogether.
Since Multichain controls the minting and burning logic of these tokens via smart contracts, supply is effectively unlimited on supported chains. This results in a superior user experience: transfers complete instantly regardless of current demand or pool balance.
A prime example is MIM (Magic Internet Money), originally minted on Ethereum. Through Multichain’s bridge integration, MIM can be instantly bridged to Avalanche, Fantom, or Moonbeam without requiring pre-funded liquidity on each destination chain.
This model offers several advantages:
- No waiting for liquidity replenishment
- Lower slippage and transfer costs
- Faster confirmation times
- Greater scalability across emerging blockchains
Projects launching new tokens or expanding to additional ecosystems benefit significantly from adopting this bridging approach.

Transfer Type (c): Hybrid Native/Bridged Assets
Some projects require a hybrid model, where certain chains use native versions of a token while others rely on bridged variants. This typically occurs when:
- A token was previously deployed on select chains before joining the Router
- Third-party bridges were used initially
- The team wants to expand to new chains without altering existing deployments
A notable example is FTM (Fantom):
| Chain | Asset Type |
|---|---|
| Ethereum | Native FTM |
| Binance Smart Chain | Native FTM |
| Fantom Opera | Native FTM |
| Cronos, Telos, Boba, Celo, Harmony | Bridged FTM |
In this setup, chains with native FTM depend on liquidity pools, while bridged chains enjoy unlimited supply. The project team must ensure adequate liquidity on native-side chains, but once bridging is enabled elsewhere, scalability becomes less of a concern.
This hybrid architecture provides maximum flexibility during transitional phases and supports gradual ecosystem expansion.

Frequently Asked Questions (FAQ)
Q: What happens if there’s not enough liquidity to complete my transfer?
A: If the destination chain lacks sufficient native tokens, you’ll receive anyTokens representing your claim. You can redeem them later when liquidity is restored by removing your pool share.
Q: Are bridged assets safe? Who controls their supply?
A: Bridged assets are secured by smart contracts (e.g., AnyswapV5ERC20.sol) and governed by Multichain’s SMPC network. Supply is controlled algorithmically—minted when deposited, burned when withdrawn—ensuring 1:1 backing.
Q: Can I lose money if a chain runs out of liquidity?
A: No. Your funds are never lost. If liquidity is low, you simply hold anyTokens until enough native tokens become available in the pool for redemption.
Q: How does the SMPC network ensure security?
A: The SMPC network uses threshold cryptography across distributed nodes to sign transactions without exposing private keys. This prevents single points of failure and resists common attack vectors.
Q: Is there a fee for cross-chain transfers?
A: Yes, minimal fees cover gas costs and network operations. These vary by chain congestion and asset type but are generally lower than alternative bridging methods.
Q: Can I use the Cross-Chain Router for NFTs or only fungible tokens?
A: Currently, the Cross-Chain Router supports ERC-20 and similar fungible tokens. NFT bridging requires separate protocols and is not natively supported in this system.
Optimized Liquidity Sharing & Security Measures
To further enhance efficiency and reduce user costs, Multichain employs a shared liquidity tool powered by the SMPC network. This allows select high-trust chains (like Ethereum and Binance Smart Chain) to temporarily share liquidity between Router and Bridge systems.
While this feature isn’t active continuously, it provides critical initial liquidity during peak demand or after large transfers. All participating chains undergo rigorous security evaluations to ensure risk exposure remains within acceptable limits.
Security safeguards include:
- Chain TVL (Total Value Locked) caps
- Dedicated security funds
- Emergency suspension mechanisms
- Real-time monitoring via Watch Dog systems
These layers work together to protect user assets while maintaining operational agility.
