Summary
Cross-chain bridges play a vital role in transferring assets between different blockchains. Bridging from Polygon to Arbitrum is straightforward due to their EVM compatibility, allowing you to use a single wallet like MetaMask for the entire process. This guide explores efficient methods, fees, and alternatives for seamless transfers.
Can I Bridge from Polygon to Arbitrum?
Yes! While Polygon’s native bridge doesn’t support direct transfers to Arbitrum, third-party solutions like Hop Protocol enable secure asset movement between these Layer 2 networks. Both chains are EVM-compatible, simplifying the process to just a few steps with one wallet.

Step-by-Step Bridging Using Hop Protocol
- Visit Hop Bridge: Navigate to the Hop Bridge interface.
- Select Networks: Choose Polygon as the source and Arbitrum as the destination.
- Choose Token: Pick the asset (e.g., USDC, ETH).
- Enter Amount: Specify the transfer quantity.
- Confirm Transaction: Approve the swap and pay gas fees (MATIC for Polygon, ETH for Arbitrum).
Security Note: Hop uses bonders (liquidity providers) and bundles transactions via native bridges to minimize risks.
Bridging Fees Explained
- Bonder Fee: ~$0.01 USDC.
- Destination Tx Cost: <$0.01 USDC (varies with L1 gas prices).
- Total: Typically under $0.02. Aggregators may add extra charges.
Top Alternatives to Hop Bridge
| Bridge | Supported Chains | Key Features |
|---|---|---|
| Router Protocol | 5+ L1/L2 | Multi-directional, contract-level data |
| Orbiter Finance | 63+ | Low-fee, instant Ethereum transfers |
| Symbiosis | 34+ | Aggregates liquidity for non-EVM swaps |
Why Bridge Between Polygon and Arbitrum?
- Scalability: Both reduce Ethereum’s congestion.
- Low Costs: Minimal fees compared to L1.
- EVM Compatibility: Unified wallet management.
FAQs
1. Can I transfer NFTs between these networks?
Yes, but only if the bridge supports NFT transfers (check bridge docs).
2. How long do transfers take?
Usually minutes, but delays may occur during peak congestion.
3. What gas tokens are needed?
- Polygon: MATIC.
- Arbitrum: ETH.
4. Are all tokens bridgeable?
Most major tokens (e.g., USDC) are supported, but verify before transferring.
5. Is there a limit on transfer amounts?
Limits depend on the bridge’s liquidity pool.
Final Thoughts
Bridging between Polygon and Arbitrum unlocks flexibility for DeFi users. With tools like Hop Protocol and competitors like Router Protocol, you can optimize for speed, cost, and security. Always verify transaction details and gas fees before proceeding.
