Check current gas prices on source chain explorer for bridge 'send' or 'approve' txs.For claiming/receiving assets, if required by the bridge.For swaps within the bridge or low liquidity. Estimate if anticipated.
Total Estimated Fee Calculation
Bridge Provider Percentage Fee Amount: $0.00
Total Estimated Fees: $0.00
Total Estimated Fees as % of Amount Bridged: 0.00%
Important: This is an estimate based *solely on your inputs*. Actual fees can vary significantly due to network congestion (gas prices), bridge-specific dynamic fees, and actual slippage. Always verify the final fee breakdown on the bridge platform itself immediately before confirming any transaction.
Understanding Bridge Fees & Risks
Gas Fees: Paid to network validators/miners for processing transactions on the source and (often) destination blockchains. Highly volatile and depends on network congestion (e.g., Ethereum Gwei, Polygon Matic).
Bridge Provider Fees: Charged by the bridge operator for using their service. Can be a small fixed fee, a percentage of the transaction value, or a combination.
Slippage: Occurs if the bridge involves an Automated Market Maker (AMM) or token swap, or if there's low liquidity for the asset pair. It's the difference between the expected price of a trade and the price at which it's actually executed.
Why Fees Vary: Network demand, the complexity of the bridge's smart contracts, the specific assets being bridged, and the bridge's own operational model all influence costs.
Security: Cross-chain bridges have been targets for exploits. Research the bridge's reputation, security audits, insurance (if any), and total value locked (TVL) before use. Prefer well-established and audited bridges.
