If i will be given a chance to do a project with cryptocurrency then i will be making an all in one digital wallet for all crypto that includes bitcoin and all altcoins using same wallet address. I have seen too many digital wallet from known digital wallet for ERC20 tokens and for bitcoin digital wallet but i never saw a digital wallet that will cater all the digital currency either bitcoin or altcoins. If i have only the capacity to do it like having a good team developer and a financer then i guess i could make a revolutionary digital wallet.
Your goal is very wise and noble, this way of course makes it easy for all users both bitcoin and other cryptocurrencies. So whatever deals with transactions all of us may no longer need to open a lot of sites because your site can serve everything All In One. However although your goal is very noble, it seems that you will have some obstacles as has been said by
.
A wallet which does create the same
address for each crypto currency is not possible.
(Almost) each cryptocurrency does have its own address format.
What you might be refering to is a wallet which holds private keys for multiple cryptos derived from one seed. This is possible. And it does exist.
Exodus is such a wallet.
But note that quite a few people have connection issues when using exodus. It also just had a vulnerability discovered which allowed an attacker to dump the private keys out of the RAM once the wallet was opened. I am not sure about which versions are affected.
The ledger nano s does also support multiple cryptocurrencies. And in addition to that the private keys (and the seed generation) are secured by a secure element and a 2-FA through the buttons/screen.
Once they release their native application, you will be able to
monitor all your holdings in a dashboard.
