Common questions
What is gwei?
A billionth of an ETH. Gas prices are quoted in gwei because the amounts are otherwise unreadably small.
Why do fees change so much?
They rise with demand for block space. Weekends and quiet hours are usually far cheaper, and the swing across a day can be several times over.
