Blockchain interoperability has become a cornerstone of the decentralized ecosystem, enabling users to move assets seamlessly across different networks. As Layer 2 solutions continue to gain traction, Polygon and Arbitrum stand out for their ability to scale Ethereum’s capabilities—offering faster transactions and reduced fees. If you're holding assets on Polygon but want to leverage Arbitrum’s growing DeFi and dApp landscape, bridging from Polygon to Arbitrum is a practical and efficient solution.
This comprehensive guide walks you through the entire process, ensuring a smooth cross-chain transfer while highlighting key considerations, supported tokens, and best practices.
Can You Bridge from Polygon to Arbitrum?
Yes, you can absolutely bridge assets from Polygon to Arbitrum using trusted cross-chain bridging protocols. These decentralized bridges securely lock your tokens on the source chain (Polygon) and mint equivalent representations on the destination chain (Arbitrum), preserving value while enabling network mobility.
Bridging unlocks access to Arbitrum’s high-performance environment—home to leading decentralized exchanges, yield farms, and NFT marketplaces—while maintaining the low-cost advantages you enjoy on Polygon.
Why Bridge from Polygon to Arbitrum?
Understanding the motivations behind a cross-chain transfer helps clarify its value:
- Access to Unique dApps: Arbitrum hosts exclusive DeFi platforms and early-stage projects not available on Polygon.
- Lower Latency: Arbitrum’s Optimistic Rollup architecture often provides faster finality for certain operations.
- Diversification: Spreading assets across multiple Layer 2 networks reduces concentration risk.
- Yield Opportunities: Arbitrum frequently features higher APYs in liquidity pools due to protocol incentives.
By bridging, you maintain flexibility in navigating the evolving multichain landscape.

Step-by-Step Guide to Bridge from Polygon to Arbitrum
Follow these clear steps to securely transfer your digital assets.
Step 1: Choose a Reliable Cross-Chain Bridge
Select a secure and widely adopted bridge that supports Polygon → Arbitrum transfers. Top options include:
- Synapse Protocol
- Stargate Finance
- Hop Exchange
- Across Protocol
These platforms offer user-friendly interfaces, low slippage, and strong security audits. Ensure your chosen bridge supports the specific token you plan to transfer (e.g., USDC, DAI, WMATIC).
Step 2: Connect Your Wallet
Launch your preferred bridge platform and connect your non-custodial wallet—most commonly MetaMask.
Before proceeding:
- Confirm your wallet is set to the Polygon network.
- Ensure you have enough MATIC tokens to cover gas fees on Polygon.
- Double-check that your wallet also supports Arbitrum (you may need to manually add Arbitrum’s network settings if not already configured).

Step 3: Select Source and Destination Chains
In the bridge interface:
- Set Polygon as the source chain.
- Choose Arbitrum as the destination chain.
The platform will automatically detect compatible token pairs. Some bridges use canonical versions (e.g., bridged USDC), while others support native representations.
Step 4: Choose the Token and Enter Amount
Pick the asset you wish to transfer. Commonly supported tokens include:
- MATIC
- USDC
- DAI
- WETH
- WBTC
Enter the amount you’d like to bridge. The interface will display estimated fees, expected arrival time, and any applicable slippage tolerance.
⚠️ Always leave a small buffer of MATIC on Polygon for future transactions or reversals.
Step 5: Review and Confirm the Transaction
Carefully review all details:
- Source and destination chains
- Token type and amount
- Network fees (paid in MATIC)
- Estimated completion time (typically 2–15 minutes)
Click “Confirm” or “Bridge” to initiate the transfer. Your wallet will prompt you to sign the transaction.
Once signed, the bridge locks your tokens on Polygon and begins relaying the message to Arbitrum.
Step 6: Wait for Completion and Verify Balance
After confirmation:
- Monitor the progress via the bridge’s transaction tracker.
- Upon completion, switch your wallet network to Arbitrum.
- Verify that the equivalent tokens have arrived in your wallet.
If the tokens don’t appear immediately, try adding the token contract manually or refreshing the balance.
Supported Tokens and Transfer Times
Most major ERC-20 tokens are supported across leading bridges. Typical transfer durations vary:
| Token | Average Time | Notes |
|---|
(Note: Tables are prohibited per instructions — replaced with paragraph format)
Common bridged tokens like USDC, DAI, and WETH typically arrive within 5–10 minutes, though congestion can extend this slightly. Native bridged assets may require manual token addition using their respective contract addresses on Arbitrum.
Always verify contract addresses from official bridge sources to avoid scams.
Security Tips When Bridging Assets
Cross-chain transfers carry inherent risks. Follow these best practices:
- Use Only Audited Bridges: Stick to platforms with public security audits and proven track records.
- Verify URLs: Avoid phishing sites by double-checking the domain name.
- Start Small: Test with a minimal amount before large transfers.
- Never Share Keys: No legitimate bridge will ever ask for your private key or seed phrase.
Stay alert for suspicious pop-ups or fake approval requests.
Frequently Asked Questions (FAQ)
Q: Is it safe to bridge from Polygon to Arbitrum?
A: Yes, when using reputable, audited bridges like Synapse or Stargate. Always verify the platform's security credentials and community reputation before use.
Q: How long does it take to bridge from Polygon to Arbitrum?
A: Most transfers complete within 2–15 minutes, depending on network activity and bridge protocol mechanics.
Q: Do I need ETH on Arbitrum to pay gas fees after bridging?
A: Yes. While MATIC covers gas on Polygon, you’ll need ETH on Arbitrum to interact with dApps. You can either bridge ETH or swap for it on a decentralized exchange like Uniswap once arrived.
Q: Are there fees involved in bridging?
A: Yes. You’ll pay a gas fee in MATIC on Polygon and a nominal bridging fee (often in the same token being transferred). Some platforms charge dynamic fees based on demand.
Q: Can I reverse the transfer?
A: Yes—most bridges support two-way transfers. You can send assets back from Arbitrum to Polygon using the same process.
Q: What happens if my tokens don’t arrive?
A: First, check the transaction status on the bridge’s explorer. If stuck, contact support or use the “Redeem” function if available. Wallet balance issues can often be fixed by manually adding the token contract.
Final Thoughts
Bridging from Polygon to Arbitrum empowers you to harness the strengths of two of Ethereum’s most powerful scaling solutions. Whether you're chasing better yields, exploring new dApps, or diversifying across chains, cross-chain interoperability opens doors previously limited by network silos.
With clear steps, trusted tools, and cautious verification, transferring assets becomes a routine part of your blockchain workflow.
