Yup just send 1 kmd or so to yourself and the interest will be claimed.
So just to clarify, if I had 100 KMD on an address for 6 months
I could send 1 KMD from that address, to that address, and I would claim 2.5% interest on 100 KMD
1 @ 365 days = 5% for 100 KMD
Is that correct?
I should look at this explanation about how to claim your interest from holding KMD coins on your address and you must wait for a while to see your interest to add your KMD balance .
--------------------------------------------------------------------------------------------------
How to Claim your Interest
Send your whole balance back to the same address. Works using the Agama Wallet or Swing Wallet.
Note! You get your 5%APR interest as long as you claim the interest once per year.
Warning! Any z-transaction will nullify the interest.
Advanced Information
The following information is for advanced users who would like to gain a more complete understanding about how the interest works and how to reset it with properly without sending the whole balance. Let us begin.
Each UTXO accrues interest independently.
You may do a listunspent command to find out how many utxo you have.
Next, do that many small transactions one after the other before the previous ones get confirmed
The rules are simple:
1. must be over an hour old
2. must be for 10 or more KMD
3. must have nLockTime set
Accrues up to 5% of utxo amount at a rate of 5% per year
When you spend that utxo you are able to collect the accrued interest for that utxo.

I hope that you can understand the interest claim of KMD procedure.
Agama is nice, and its cool that it is a from the ground up wallet. The swing wallets are important to have in the beginning but its nice seeing projects that develop out their entirely own unique wallet
