What is a Crypto Wallet?
A Crypto Wallet is the digital space which allows us to interact with blockchain networks and manage blockchain-based funds (i.e., cryptocurrencies like bitcoin or Ethereum etc.). It enables the easy exchange of blockchain-based funds while maintaining user’s privacy and identity as well as the security of transactions are secure.
Whenever a crypto wallet is created, there is a pair keys - private key and public - linked to the wallet.
A public key (i.e., alphanumeric identifier) is generated along with the wallet, and the user can share it with others to receive crypto funds. The private key acts as a password and should not be disclosed to others. We use the private key to make transactions and exchange crypto funds.
