KMD is a unique type of Proof-of-Stake that does not require you to have a wallet online to accrue rewards. Instead it's a zero-footprint PoS. To claim interest you simply have to spend an input. If someone sends you 100 KMD in one transaction and 1 year later you wish to claim the 5% interest, all you need to do is send your balance to yourself. This is the action that the claim button automizes. The latter resets the utxo and it will materialize your interest into the spendable balance.
