from the perspective of developers, this article explains to readers how to interact with wallet and how to develop a wallet
How do we understand wallets? In short, it is an entrance to connect the blockchain. At present, mature public chains such as bitcoin and Ethereum have many wallets to choose from. Generally, the wallet needs full access to your user assets, that is, it will ask you to enter the private key. The evil cost of wallet is very low, which is one of the reasons why I suggest to choose open source wallet.

2. Decentralized or cold wallets are relatively safe. The private key is backed up by itself and can be checked on all data links. As long as the private key is not leaked, the assets will not be stolen.

3.

The digital currency wallet is the hardware wallet, which means that the private key of digital assets is stored in a single chip, isolated from the Internet, plug and play. Hardware wallet can't guarantee 100% security. For example, if a geek gets your hardware wallet and doesn't know your private key, it may be cracked by violence. It's just one of the safest storage methods compared to other storage methods

many block chain entrepreneurs at home and abroad are optimistic about the development of this field, so they begin to build more hardware wallets. In the case of the exchange being stolen a lot of money and the software wallet being stolen from time to time, many investors regard the hardware wallet as the last moat

6. The essence of a blockchain wallet is a private key, which is a random hash string. If you have the private key, you have the right to use the wallet. According to the storage method of the private key, it can be divided into cold wallet and hot wallet
cold wallet refers to the wallet where the network can't access your private key. Generally, it will take a notebook to record it. Although it avoids the risk of being stolen by hackers, it may also be lost
a hot wallet is a wallet that can access your private key on the Internet. Hot wallets are often in the form of online wallets, which are not easy to lose, but also have risks.
