Exchange offices take Euros, Dollars and Pounds. Just a warning about withdrawing money out there, you will not be able to use most ATMs that you see because of the dire situation their banks are in. Security-wise it's absolutely fine, just banks are folding left, right, centre and others have no spare cash.
If you must withdraw money (likely that you will) then your best bet will be the Euronet ATMs. There are a few along the main street Khreschatyk situated on the sides of kiosks. These are perfectly safe.
This is from personal experience two weeks ago. Have been to Kyiv many times, it's a lovely city.
Can you pay in bars and restaurants with $/€/£?
