Finding the cheapest route to bridge Polygon to Arbitrum depends on the token, the amount being transferred, and current network conditions. Gas fees on Polygon are typically very low due to the network's high throughput design, meaning the dominant cost factor is often the bridge protocol fee rather than the on-chain gas. Bridge fees generally range from 0.05% to 0.5% of the transfer amount, with flat-fee options available for stablecoin transfers.
To minimize bridge costs when moving assets from Polygon to Arbitrum, consider timing your transfer during periods of low network activity when gas prices are reduced. Stablecoin transfers such as USDC and USDT often benefit from near 1:1 conversion rates with minimal price impact. For larger transfers, the percentage-based fee structure means relative costs decrease as transfer size increases. Always review the fee breakdown before confirming to ensure you are getting the most cost-effective route.
