I agree the terms haven't settled but those examples are all pretty solid though in terms of investment lexicon if not legal one.

A £ denominated bond issued in Ireland is a eurobond but not a bulldog bond. The euro name is a bit unfortunate now as euro denominated bonds may or may not be eurobonds and that could confuse people.

In fact a crypto denominated bond would just be another kind of eurobond, so we could call it a cryptoeurobond as would gold or silver denominated ones.

In fact I think some SAFTS are basically an ETH eurobond.
