When bridging from Polygon to Arbitrum, users encounter two main categories of fees. The first is the source chain gas fee, paid in MATIC on the Polygon network, which covers the cost of initiating the bridge transaction on-chain. The second is the bridge protocol fee, which varies by platform and typically ranges from 0.05% to 0.3% of the transfer value. Some platforms also charge a small destination fee to cover the cost of releasing your tokens on Arbitrum.
Bridge fees vary depending on network congestion, token type, and the specific protocol used. During peak usage hours, gas prices on both Polygon and Arbitrum may increase slightly, raising the total cost of your transfer. Stablecoin transfers between Polygon and Arbitrum are generally the most fee-efficient because routing algorithms can find deep liquidity pools with minimal slippage. Always check the fee summary screen before confirming your bridge transaction to avoid unexpected costs.
