Daedalus is a wallet, developed by IOHK which will allow you to store Ada.
Daedalus is a Hierarchical Deterministic (HD) wallet, allowing you to create an infinite set of keys from a single seed.
Whenever you want to move your wallet, you will only need to enter your seed and the HD algorithm will find all your Ada. This means you will never have to worry about managing lots of seeds or files of keys.
