if there is no urgency to get this in a vm v5 release, then i wonder if we should target develop (vm v6) so we don't have to refactor the code from BN to bigint again

There is no urgency, will target develop

[jochem-brouwer]

Right, before I continue should first rebase on develop.

Yes, that makes a dramatic amount of sense 😜, hadn't thought about that either yet but we can very well start to do so. This will take some time to implement anyhow on these new bigger tasks, and v6 is finally not that far away any more (2-3 months I would say).
