Bridging Polygon (MATIC) ERC-20 tokens to Arbitrum enables seamless asset transfers between these two ecosystems. This process unlocks several advantages, including enhanced scalability, lower fees, and improved interoperability. Below, we outline the steps, benefits, and key considerations for bridging tokens effectively.
Key Benefits of Bridging from Polygon to Arbitrum
- Scalability: Arbitrum processes transactions faster than Polygon, accommodating higher throughput.
- Lower Fees: Arbitrum’s cost-efficient network reduces transaction costs compared to Polygon.
- Security: Arbitrum’s robust security framework ensures safe token transfers.
- Interoperability: Move tokens across blockchains effortlessly, expanding management options.

Step 2: Select Chains and Token
- Source Chain: Polygon (MATIC).
- Target Chain: Arbitrum.
- Choose the token from the dropdown or paste its contract address (for unlisted tokens).
Step 3: Adjust Gas Fees
- Set gas fees based on urgency (standard/high recommended for faster processing).
Step 4: Confirm Transaction
- Review details (wallets, fees, token amount).
- Approve the transaction and wait a few minutes for completion.
Calculating MATIC-to-Arbitrum Bridge Gas Fees
Gas fees depend on:
- Gas Price: MATIC per gas unit (varies with network demand).
- Gas Limit: Maximum gas allocated per transaction.
Formula:
Total Fee = Gas Price × Gas Limit Tools:

Cheapest Way to Bridge MATIC to Arbitrum
- Low Gas Prices: Set lower fees (slower but cheaper).
- Compare Bridges: Fees vary across platforms.
- Prioritize Security: Opt for reputable services over the cheapest option.
What Is a Blockchain Bridge?
A crypto bridge transfers assets between blockchains, enabling:
- Cross-Chain Compatibility: Use non-native assets (e.g., MATIC tokens on Arbitrum).
- Cost Savings: Leverage lower-fee networks.
- Expanded Access: Tap into diverse DeFi ecosystems.
Types of Bridges:
- Decentralized: Community-operated (e.g., ChainPort).
- Centralized: Managed by single entities.

FAQs
1. How long does bridging take?
- Typically 2–10 minutes, depending on network congestion.
2. Can I bridge any ERC-20 token?
- Yes, if the token has liquidity on Arbitrum. Unlisted tokens require manual contract entry.
3. Are there risks in bridging?
- Smart contract vulnerabilities or incorrect recipient addresses may pose risks. Always verify details.
4. Why choose Arbitrum over Polygon?
- Arbitrum offers lower fees and Ethereum-level security via optimistic rollups.
About Polygon (MATIC)
- Layer 2 Solution: Enhances Ethereum scalability via sidechains.
