I need the Dogecoin lightweight wallet to use it in my application.

I am implementing a Java application that needs to perform transactions on the Dogecoin blockchain. So you need a lightweight wallet to sign and send transactions. This may be a Java library or a command-line tool to be run within Java code. I found Dogecoin Core and Multidoge, but the first problem is that it has to be a full node, and the second is that it is a graphical application and cannot be used as a library or command line tool. Any suggestions? Which tool best suits my needs? Any help would be greatly appreciated.
