Lens balance incorrect

Uh, just realized the decimalization is different, and that it's just rounding - however it is slightly odd to have 6 decimal places when there are 9, maybe we should have some form of expansion to show that there are further points?

Also after some testing, I see the smallest decimal increase when making transactions, which makes it feel like the fee is being added instead of deducted

should be fixed by #56
