Tokenomics and interest?

Hi.
Im interested in knowing if it is possible to implement a couple functions, without completely have to alter the plugin code?

1. Tokenomics.
Would it be possible to cap the credit supply?
I mean, you could issue 100.000 credits, and that would be the total supply.
Your base peg price would then change, according to how many that actually bought credits. (Yes, its easier doing smth like that with solidity and web3 ?? )

2. Interest.
Would it be possible to set a fixed apr, or compounding apy on someones wallet, so they could earn interest based on an apr/apy rate you set as an admin?

Both suggestions would probably be an idea for a plugin extension,
but i would really like to see these fuhnctions.

If it is possible for you to ballpark how much you wouldve needed to make something like that on a custom install, id appreciate as well.

Thank you ??
