How to Use Multichain for Cross-Chain Transfers in 2025

AI-generated summary
As decentralized ecosystems expand, the need for cross-chain token transfers becomes essential. Multichain is a decentralized protocol that facilitates seamless asset bridging across over 80 blockchains, including Ethereum, BNB Chain, and Arbitrum, using Secure Multi-Party Computation (SMPC) for secure transactions. To use Multichain, users need to connect a supported wallet, select the source and target blockchains, choose the token to transfer, and approve the token if necessary. After initiating the transfer, users can track the status and will receive their tokens on the destination chain. Best practices include verifying the website, checking token addresses, avoiding high gas periods, and starting with small test transactions. While Multichain supports many tokens, not all are available on every chain, and users should be aware of the risks involved in bridging. Transactions are irreversible, and minimal fees apply. In conclusion, mastering Multichain is crucial for anyone involved in the evolving Web3 landscape, whether for trading, DeFi, or developing multichain applications.

As decentralized ecosystems grow, the ability to move tokens between blockchains is no longer a technical luxury — it’s a necessity. Whether you're active on Ethereum, BNB Chain, Polygon, or newer L2s like Arbitrum, interoperability is essential. That’s where Multichain comes in — a decentralized cross-chain bridge enabling seamless transfers across over 80 blockchains.

This guide walks you through how to use Multichain safely and efficiently in 2025, covering key steps, risks, and best practices.

What Is Multichain?#

Multichain is a decentralized protocol that allows you to bridge assets between different blockchains without relying on centralized intermediaries. Using a network of Secure Multi-Party Computation (SMPC) nodes, it validates and executes cross-chain transfers securely and efficiently.

It supports a wide array of networks, including:

Ethereum

BNB Chain

Arbitrum

Optimism

Avalanche

Fantom

Polygon

Its codebase is open-source and publicly available on Multichain GitHub, reinforcing its transparency and community trust.

Why Use Multichain?#

Interoperability: Move tokens across chains without relying on CEXs

Efficiency: Fast bridging times with low transaction fees

Decentralization: Uses SMPC validation to minimize trust

Wide Support: Compatible with major chains and new L2s

Secure: Proven architecture used by leading protocols

Step-by-Step: How to Use Multichain#

  1. Connect Your Wallet
    Welcome to Multichain and connect a supported wallet such as:

MetaMask

WalletConnect

Coinbase Wallet

Make sure your wallet is set to the source blockchain you want to send assets from.

  1. Choose Networks and Token
    Select:

From: the blockchain you’re sending from (e.g., Ethereum)

To: the target chain (e.g., Arbitrum)

Token: the asset you want to transfer (e.g., USDC)

Multichain will automatically calculate the minimum amount, fees, and estimated arrival time.

  1. Approve Token (If Required)
    For ERC-20 tokens, you’ll need to approve Multichain to interact with your token before you can bridge it. This only needs to be done once per token.

  2. Initiate Transfer
    Click Transfer, then confirm the transaction in your wallet. You’ll pay gas fees in the native token of the source chain (e.g., ETH for Ethereum).

  3. Wait for Confirmation
    Most transfers are completed within 1–5 minutes depending on network congestion. You can track the status in real-time directly on the site.

  4. Receive Tokens on Target Chain
    Once complete, your bridged tokens will arrive in your wallet on the destination blockchain.

Be sure to add the token manually in your wallet if it doesn't show up immediately.

Best Practices When Using Multichain
Always verify you’re on the correct website: Multichain

Double-check token addresses on both chains

Avoid bridging during periods of high gas prices

Use small test transactions if you’re a beginner

FAQ: Frequently Asked Questions#

  1. Can I bridge any token using Multichain?
    Multichain supports a wide range of tokens, but not every token is available on all chains. Check the dropdown list on the UI for supported pairs.

  2. How long does a transfer take?
    Most transfers complete within 5 minutes, but can vary based on network congestion and block finality.

  3. Are there risks when bridging?
    Yes. Like all cross-chain bridges, Multichain carries smart contract and protocol-level risks. Use small test amounts first and avoid unknown tokens.

  4. Can I reverse a transaction?
    No. Blockchain transactions are final. Always double-check your destination chain and wallet address before confirming.

  5. Is there a fee to use Multichain?
    Yes, minimal protocol and network fees apply. These are shown before you confirm any transaction.

Conclusion#

Cross-chain functionality is no longer an advanced feature — it’s the future of Web3. With its robust architecture and decentralized validation, Multichain offers one of the most secure and scalable solutions available today.

Whether you’re a trader moving stablecoins, a DeFi user optimizing yield, or a developer enabling multichain dApps — understanding how to use Multichain is essential in 2025.
