Bridging tokens from Polygon to Arbitrum is one of the most common cross-chain operations in DeFi. Both networks are Ethereum Layer-2 solutions, but they use different consensus mechanisms and cannot directly exchange assets without a bridge.

Why Bridge from Polygon to Arbitrum?

Polygon is a high-throughput sidechain optimised for low-cost transactions, while Arbitrum is an Optimistic Rollup that inherits Ethereum's security. Moving assets between the two lets you access Arbitrum-native dApps — such as perpetual exchanges and advanced DeFi protocols — while starting from liquidity you already hold on Polygon.

Step 1 – Connect Your Wallet

Open the bridge interface and click Connect Wallet. MetaMask, WalletConnect, Coinbase Wallet, and most EVM-compatible wallets are supported. Make sure your wallet is set to the Polygon network before proceeding.

Step 2 – Select Polygon as Source Chain

In the "From" dropdown, choose Polygon. Then select the token you want to transfer — USDT, USDC, ETH, POL, or any other supported asset.

Step 3 – Select Arbitrum as Destination Chain

In the "To" dropdown, select Arbitrum One. The interface will automatically show you the estimated amount you will receive after bridge fees.

Step 4 – Enter Amount and Review Fees

Type the amount you want to bridge. Review the gas fee on Polygon (paid in POL/MATIC) and the estimated receive amount on Arbitrum. Cross-chain transfers typically complete in under 60 seconds.

Step 5 – Approve the Transaction

If this is your first time bridging a specific token, you will be asked to approve the spending limit. Set a spending cap, then confirm the bridge transaction in your wallet.

Step 6 – Receive Tokens on Arbitrum

Once the transaction is confirmed, your tokens will appear in your wallet on the Arbitrum One network. You can verify the transfer on Arbiscan or Polygonscan.

Tips for a Safe Bridge Experience

Always double-check the destination address. Ensure you have enough POL on Polygon to cover gas fees. Start with a small test transfer before moving large amounts. Most cross-chain transfers complete in 1–10 seconds using liquidity-based bridges.
