When To Use txcosts

• Compare typical transaction cost across chains

• Track fee affordability trends over time

When Not To Use txcosts

• You need total fees paid instead of typical per-transaction cost

• You need transaction volume

Caveats

• txcosts is a median-style cost metric, not total cost.

• Aggregate comparisons across chains use a weighted-mean style aggregation in growthepie metadata.
