How to make a hardware wallet for storing cryptocurrency from an old smartphone?

Published

In the world of cryptocurrency solutions for secure storage will always be in demand. It is unlikely that demand will decrease, since the number of hardware wallets is very small now.

New software Parity Signer V2.0 can turn almost any mobile phone into a hardware wallet, without resorting to additional equipment, writes Nulltx .

The Parity Signer team has found a new solution that includes the functionality that advanced cryptocurrency users need – a hardware wallet in which the funds are under control at any time.

Today, devices such as Ledger Nano S , Trezor and KeepKey provide secure storage, while these hardware wallets are far from cheap. In addition, there may be delays when connecting them.

To solve this problem, Parity Signer turns an old or modern phone into a hardware cryptocurrency wallet . This is done using software that makes customization very convenient. The application is available for users of iOS and Android, and allows you to breathe new life into the old smartphone, which you have ceased to use.

It is important to note that Parity Signer V2.0 is released in beta, so there may be errors in the application, which is why you should not keep significant amounts there, at least until a future release.

It is noteworthy that this application supports different currencies and their respective test networks, for example, Ethereum , Ethereum Classic , The Ropsten Testnet, etc. In addition, the application sends safety notifications to users warning of safe or unsafe use of the device. This function can be called unique.

The proposed solution is designed to work on devices that are not connected to the Internet, which is why a spare or outdated phone becomes useful again. Of course, this is an experimental solution, but it certainly can be useful for many cryptocurrency users.
