The Cross-Chain Router by Multichain enables frictionless transfer of assets—whether native or bridged—across multiple blockchains. This guide explores its three routing mechanisms, operational workflows, and advantages for decentralized finance (DeFi) users.
How Multichain’s Cross-Chain Router Works
Multichain’s technology facilitates interoperability between blockchains through three routing categories:
1. Native Assets Routing
Definition: Tokens already existing on a blockchain (e.g., USDC on Ethereum).
Mechanics:
- Liquidity Pools: Users deposit tokens into pools on each chain. Transfers deduct from the source chain’s pool and credit to the destination chain’s pool.
- anyXYZ Tokens: If liquidity is insufficient, users receive anyXYZ tokens (representing their claim on future liquidity). When XYZ tokens become available, users manually redeem anyXYZ via the "Remove" function.
Process Flow:
- User deposits XYZ tokens into Chain A’s pool.
- anyXYZ tokens are minted on Chain A and burned upon transfer.
- SMPC nodes mint equivalent anyXYZ on Chain B.
- If Chain B’s pool has enough XYZ, tokens are auto-sent to the user’s wallet; otherwise, anyXYZ remain until redeemed.
Key Insight: Liquidity pools rebalance as users route tokens across chains or add/remove funds.

2. Bridged Assets Routing
Definition: Tokens created via Multichain’s AnyswapV5ERC20.sol contract (e.g., MIM).
Advantages:
- Unlimited Liquidity: Multichain controls minting, eliminating pool shortages.
- Streamlined UX: Users bypass liquidity checks—transfers are instantaneous.
Example: MIM bridges from Ethereum to Avalanche via AnyswapV5ERC20 contracts integrated into the Router.
3. Hybrid Native/Bridged Assets Routing
Definition: Combines native tokens on some chains with bridged tokens on others (e.g., FTM).
Use Case: Projects expanding to new chains while maintaining existing native supplies.
Responsibility: Project teams must ensure adequate liquidity for native pools; bridged chains have unlimited supply.
Example:
- Native FTM: Ethereum, BSC, Fantom Opera.
- Bridged FTM: Cronos, Harmony, Celo.
Optimizing Liquidity Efficiency
Multichain’s Shared Liquidity Tool (powered by SMPC networks) reduces cross-chain costs by pooling resources between Routers and Bridges on select chains.
Features:
- Limited to initial liquidity provisioning.
- Risk-mitigated via Chain TVL caps, Security Funds, and real-time monitoring.
FAQs
Q1: What happens if a destination chain lacks sufficient liquidity?
A: Users receive anyXYZ tokens redeemable later via the "Remove" function.
Q2: Are bridged assets safer than native assets in the Router?
A: Yes—bridged assets eliminate liquidity risks since Multichain controls minting.
Q3: How often is shared liquidity updated?
A: Infrequently; primarily for bootstrap liquidity with stringent security checks.

Key Takeaways
- Native Assets: Depend on liquidity pools; use anyXYZ for shortages.
- Bridged Assets: Offer unlimited liquidity via smart contract control.
- Hybrid Routing: Balances native and bridged tokens for scalability.
Multichain’s Cross-Chain Router combines flexibility, security, and efficiency—making it a top choice for decentralized cross-chain transfers.
