Is it possible to create such a wallet?

[btvGainer]

Is it technically possible to create a desktop wallet where we can store all crypto including bitcoin and all existing and to be launched coin in one wallet? I know one can keep them in online exchanges but it is risky.

It is possible to do so, but AFAIK, no such wallet exists.

To be launched? If it doesn't have a blockchain, it cannot have a wallet.

Now, for the existing ones, it can be done, but it's quite some work and nobody will use it.
Just imagine how big is the blockchain for Bitcoin to load. Now, each coin has its own chain, which has to be downloaded. Each coin has its own daemon in a way or another which will have to stay in memory.
The result will be something big that needs a lot of resources and which nobody will fully use, since nobody cares of ALL cryptos. Even the small exchanges de-list the coins with low volumes to free resources...

It could be an SPV wallet. That would certainly save on space. It could also use pruning.

It doesnt have to have a local blockchain, nor does this impede its security.

Electrum/Coinomi can be easily ported to suit any Cryptocurrency; in particular Coinomi can handle multiple cryptocurrencies as long as the chains are hosted alongside given Electrum server.

But are there SPV wallet for all coins? Can they be done?
I don't know that much. First thing that comes into my mind is Cryptonote/Monero: there the simple wallets I know of use a "trusted" public daemon, which I am almost certain it has the whole chain. From what I've read SPV wallet is a quite different thing....

I don't know as I haven't studied all coins. For coins that are based upon Bitcoin, SPV wallets are possible.

yes this is 100% possible we are developers and we can make stuffs which are not exists but we can make some software and sites depending on our desired work we make them ourself you can do it too if you had some technical knowledge

[calkob]

also no one wants to keep their coin at an exchange that is just crazy,,,,,,

Technically  it's possible to create that. But the problem is you need to download every blockchain if not you can not sync. You just need run their coin daemon and then your application connect to coin daemon.

Isn't this wel... not true? How does Electrum do it then where you dont' need to download the blockchain? If other alts ran similar Electrum servers, then this would be possible without blockchain download.

With cold storage, we dont need to download blockchain we just need to keep private key. Your argument very interesting for me to research more about this. thx mate

Yea it is possible to create a wallet but the problem is security. You should know the programming language fluently and you should know about every possible bugs and security loop hole in your wallet. If you don't care about wallet security then u can make one but you can't trust your wallet, dark guys could easily make your wallet empty in a matter of minutes to hours

security is a problem ,indeed, but if we add 2fa to that wallet,reduce the risks.anyway,people holds different coins , so it would be difficult to compile a wallet for every specific user,unless is done with certain standart coins(don't forguet the pos coins, needs to be mintable in the new wallet)so, thinking and thinking about , just found a lot of ''issues''.

[barrysty1e]

it wouldnt be impossible to have one wallet natively store multiple chains under the one hood (not thinwallets with a server backend).

however it would be an absolute b**tard to write; and performance would be lacking,
however; it should be able to utilize the same code for each wallet (depending on algo), as long as separate rules are applies for the intricacies of each currency (block time, block retarget algo, b58enc scheme).

They've already made this.  Jaxx. 

[DPAY]

It's possible. Security could be a stuck for those multiple wallets.

coinomi is good i agree, but it still requires the separate rpc server & electrum backend per coin. i think what poster is after is a self-contained wallet that can operate on its own.

also coinomi is not without bugs..
