Fees explained (gas)
If crypto feels confusing, gas is usually the reason. Here’s a clear explanation.
What gas is
Gas is the cost you pay to use a blockchain. It compensates validators for including your transaction and running computation. Think of it like “network fuel”. If the network is busy, fees generally rise because users compete for limited block space.
Why fees change
- Network congestion (more demand for block space)
- Complex transactions (swaps and contract calls cost more)
- Fee market settings (gas price / priority fee)
How to reduce fees (safer methods)
- Use Layer‑2 networks when appropriate (example: Base)
- Try again during less busy hours
- Keep swaps simple (avoid multi‑hop routes if not needed)

Fee myth: “failed = free”
A failed transaction can still consume computation and therefore still cost fees. If a contract “reverts,” the network already did work. This is why your wallet or explorer might show a paid fee even when the outcome is “failed.”
