These things tend to be kept secret, but some deductions are possible.

Its a pretty reasonable assumption that they'd have done what they do for other such nations (eg: France, China, India), and pressure them to join the Nuclear Non-Proliferation Treaty. France and China signed on in 1992, and India still refuses to sign.
Ukraine of course, along with the other former soviet "republics" that happened to house atomic weapons, signed all those weapons over to Russia, and then signed on as a non-nuclear power.
As a nuclear power, a nation's main responsibilities are to not provide any tech or material help to non-nuclear powers that might help them develop nuclear weapons (or any at all to non-signatories), and to work towards disarmament in themselves and others. However you have to be allowed to sign on as a nuclear power. Pakistan has said they'd be willing to join that way, but no such offer has come.
For nations that own atomic weapons and join? Well, arguably not a lot of progress has really been made on disarmament. The US and Russia have gotten rid of a lot of their thousands of obsolete weapons, but they both still have plenty more. No signed-on power has ever dropped down from Nuclear to non-Nuclear status. Ukraine and the other former Republics were really (supposed to be) the success story there.
For nations that own atomic weapons and have not signed on, there you have to look at countries like India, Pakistan, and North Korea. All nuclear exports are supposed to be banned to such countries, which means they'd have a hard time getting any fuel for their nuclear power plants that they can't dig up on their own territory. It looks like Ukraine currently have 4 of those operating, with 15 reactors.
So there were definite non-military benefits to Ukraine for disarming. At the time Russia was a friendly democratic nation, so an attack from that quarter would have seemed much less likely than under the despotic Putin-run Russia that was still, at that time,a few years in their future. In exchange they got right on the NPT treaty with its access to the international nuclear trade with relatively little fuss.
