Will KIP-9 require Kaspa wallets, pools, and exchanges to make changes?

Yes — KIP-9 specifies that ecosystem software such as wallets, pools, and exchanges will need to adapt to the new mass formula. The proposal explicitly describes how these services should update without degrading quality of service for their users. In practice this means developers update transaction-construction logic behind the scenes; ordinary users transacting on Kaspa should not experience a disruption. This matters because it shows KIP-9 was designed with real-world compatibility in mind — the change lives at the protocol layer, not as a burden placed on end users or businesses built on Kaspa.
