Should we accrue interest on collateral adjustments?

[MerlinEgalite]

Adding or withdrawing collateral does change the utilization rate so accrueing interest is not necessary from what I understand

[MathisGD]

It is necessary for withdrawCollateral because you need it for the health check.

But for supplying it is useless, nice catch ! Let's open a PR (nb: I'm in favor of keeping a comment for that).

[MathisGD]

NB: interests need to be accrued when either:

• utilisation change (because it changes the rate) or
• you need to know the latest balance to do something (eg health check)

Assigned myself to the issue but waiting for the others do give their thoughts

[MathisGD]

I think that you can go there is no real tradeoff here

[Rubilmax]

No because it's not required

[MathisGD]

for supplyCollateral, not withdrawCollateral*
