A K21 wallet doesn't store the actual K21 tokens but is essential for managing your K21 address using private keys. These keys enable you to access and control your K21 resources on the blockchain. Essentially, the wallet serves as a safekeeping and management tool for sending, receiving, and overseeing your K21 collections and assets.

How does a K21 wallet work?

The functioning of a K21 wallet revolves around the use of public and private key pairs.

To access or transfer funds, the corresponding private key is necessary. At Tangem, private keys are securely generated and stored within its technology.
