Network fees

A transaction can include costs at the network level and additional charges from applications or providers. Understanding the distinction helps you compare the full route rather than focusing on a single quoted number. This guide explains fee concepts across Bitcoin, Ethereum, and Solana using clearly hypothetical examples where arithmetic is useful. It does not supply a live fee quote or promise an execution time. Read it before a sequence involving approvals, swaps, bridges, or cash-out steps, because several actions can each introduce a cost. Check the current confirmation screen and understand an error before repeating a transaction that may already have incurred a fee.
