Swing wallet works perfectly for me . It is very reliable and safe . Albeit the blockchain loading too slow, I really recommend it . But I think few revisions on Agama will nail it in terms of UI/UX
How do you accumulate interest with swing ?
Komodo earns its interest through blockchain . It does not need a wallet to earn it as long as you have the private key or the Mnemonics passphrase. Both Agama and swing wallet reflect the interest earned by the balance of your KMD . You just need to manually claim it.
Latest agama wallet has a "claim interest" button, by the way. Super handy!
