KDE Wallet Manager is a tool to manage the passwords on your KDE system. By using the KDE wallet subsystem it not only allows you to keep your own secrets but also to access and manage the passwords of every application that integrates with the KDE wallet.
Using the KDE Wallet to store ssh keys
Install Ksshaskpass from comunity repo:
pacman -S ksshaskpass
Create the file
Add this content
#!/bin/sh export SSH_ASKPASS=/usr/bin/ksshaskpass ssh-add </dev/null
Make it executable and run
chmod +x ~/.kde/Autostart/ssh-add.sh ~/.kde/Autostart/ssh-add.sh

You may need to go to system settings -> advanced -> Autostart -> add script in newer version of KDE.
