About this benchmark
We measure the effective fee each bridge charges. the bottom-line cost a user pays, fees plus slippage plus destination gas. as a percentage of trade size. The harness uses Prometheus gauge `bridge_cost_percent` rather than the narrower `bridge_fees_percent` because providers structure pricing differently. some charge an explicit fee, others bake it into the spread. Comparing only the explicit fee field would let aggregators with implicit pricing show a misleading 0%. Sampled at $300 notional so small-amount fixed-fee blowups don't skew the percentile aggregates. Lower is better.
Methodology
- ·Routes: USDC pairs spanning Solana, Base and Arbitrum.
- ·Reference notional: $300 USDC. Smaller sizes ($5, $50) are captured by the harness but excluded from this report.
- ·Cost: `bridge_cost_percent{amount_usd="300"}`, in percent of notional. Includes fees + slippage + destination gas.
- ·Cadence: full sweep every 5 minutes for 24 hours.
- ·Region: eu-west (single point. multi-region requires running additional monitor instances).
- ·Failures (quote_failed, unsupported route) excluded from cost aggregates and counted toward success rate.
