The Dutch military intelligence agency MIVD had infiltrants in Ukraine after MH-17 of a plot to blow up the Nord Stream, they tipped off the CIA, who in turn warned Ukraine not to do it, three months before it happened; source [0], translation [1].
Germany has issued an arrest warrant for a Ukranian national [2] who along with two accomplices was on board the yacht Andromeda, which was located at the blast site days before the blast and on which traces of the same explosive was found as used on the pipelines, as well as DNA evidence.
I suppose it's not "actual evidence Ukraine did it", but it's more than enough evidence to make a Ukranian national that since fled back to Ukraine a suspect.
> The two other suspects, a married couple who do not have warrants issued in their names, have denied knowing Z. and said that they were on vacation in Bulgaria when the attack took place.
