In practice, users hit three problems every week: (1) picking the slowest bridge, (2) selecting the wrong token variant, and (3) transfers that sit "pending" for hours. Each of those costs real money. This guide covers the fastest, cheapest Arbitrum-to-Base bridge routes in 2026, plus exactly what to do if your transfer is stuck. Why Bridge Arbitrum to Base?
