Frequently Asked Questions
How do I bridge from Arbitrum to Base?
Choose Arbitrum as the source and Base as the destination in a bridge or route aggregator, pick the token and amount, review the quote and the minimum received amount, then confirm in your wallet. Keep some Arbitrum native token to pay the fee.
How much does it cost to bridge Arbitrum to Base?
The cost combines the Arbitrum network fee, the route or bridge fee and any price impact. It changes with network conditions, so use the live quote and compare the final received amount, not just the headline fee.
Is bridging Arbitrum to Base safe?
Bridges add risk beyond a normal transfer. Use a trusted interface, verify the destination network and recipient address, start with a small test amount for new routes and never share a seed phrase.
