What to know after you check
C-Chain fees are not fixed. The base fee moves with network demand, and a priority fee can affect how quickly a validator includes the transaction. The final charge can differ from the wallet estimate. The IRS treats crypto as property, so keep the explorer page or a screenshot with the transaction hash for your tax records.
