Why gas fees exist
Gas fees prevent spam and compensate the network for computation and block space.
More complex transactions typically consume more resources and may cost more.
Why fees change
- Network congestion
- Blockchain used, such as Ethereum, Base, or Polygon
- Transaction complexity
- How quickly you want the transaction confirmed
Simple way to think about it
Gas is like paying for blockchain processing power and priority.
When demand is high, the cost to get into a block can increase.
