ETH is the native currency of the Ethereum ecosystem and is required for gas fees on both Polygon and Arbitrum networks. Bridging ETH from Polygon to Arbitrum allows users to participate in Arbitrum's DeFi ecosystem, pay for transactions on Arbitrum One, and access decentralized applications that require ETH as collateral. The cross-chain transfer locks your ETH on Polygon and releases an equivalent amount on Arbitrum.
To bridge ETH from Polygon to Arbitrum, you need a Web3 wallet such as MetaMask connected to the Polygon network. Select ETH as the token, input the amount you wish to transfer, and choose Arbitrum as the destination chain. The bridge will display the expected output and estimated gas fees before you confirm. Once the transaction is submitted, the bridging typically completes within 1 to 5 minutes depending on network congestion.
