Bridging Base: routes and measured costs

Snapshot Data gate passed

Key findings

As of 3 Nov 2026, 11:35 UTC (run #540), upswap samples 15 routes that touch Base: 7 leaving it and 8 arriving. At $200 the cheapest quote on these routes came from Eco (10), Across (3), Layerswap (1), Celer (1). When Base is the source chain, the source-gas estimate (upswap gas basis v1, same for every bridge) ranged $0.0019–$0.0032 per route, shown separately from bps. Real-money tests: none yet.

How have bridge costs on Base routes changed over time?

Not enough data · 8/14 days

Over the last 336 runs (8 UTC days), the lines show each bridge's median cheapest $200 quote across the 15 routes that touch Base, in bps excluding gas. Every route had at least one rankable quote in 336 of 336 runs; the share of quote requests answered never fell below 90.4%. With under 14 days of history this is shown, not called a trend.

What this page does not claim

Chain security, finality and RPC reliability for Base are not rated here (待核实). Gas is an estimate (upswap gas basis v1, from the quote APIs at quote time), not a measured fee. See the glossary and methodology.
