Since 2009, and especially over the past few years, cryptocurrency development has become a skill in high demand. Whether you are looking to create a new currency or contribute to an existing project, creating a new user-friendly wallet is a necessary part of the process. This includes creating a front-end and a back-end to the client.
For inspiration, you should take a look at the source code of some of the top cryptocurrency wallets. If you wish to compete with what’s on the market, features like offline cold storage, paper wallet generation, or asset management would be well received.
