Cardano is a cryptocurrency project that was established in 2015 and since then it has been competing with the earlier ones. Ada is the coin of this project and daeedalus is the only wallet that supports Ada. So daeedalus is an integral wallet to cardano project. As a matter of fact, they go hand in hand.
It is impressive to know that daeedalus was created majorly for this purpose. No wonder it is designed with high profile security. The wallet was written with Haskell, a programming language known for complex mathematical logic. Hence it is a wallet with a good cryptographic signature for security.
Being an online wallet, one can only use it with desktop but it is good to know that it supports all desktop Platforms. But it doesn't support mobile devices.
Transaction fee is fair compared to what is obtainable in other wallet.
If you have opportunity of keeping Ada, you will readily agree that daeedalus is a good wallet.
