How it works
Fee mechanisms differ by network. Some systems use auctions, base fees or priority fees, and the cost may change with congestion and transaction complexity.
What to check
Check the network's fee unit, what the wallet estimates and whether the transaction can be repriced or replaced. Exchange withdrawal fees are separate from protocol fees.
- Separate protocol and exchange fees
- Check congestion
- Confirm network compatibility
Limits and risks
A low-value transfer can become uneconomic when network fees spike. Choosing a cheaper network also introduces compatibility and bridge risks.
