# Wallets

Each user of TEOS platform can have one or more wallets. **Wallets are used to keep sparks of assets owned by a TEOS user**. Each wallet consists of a pair of public address and private key.

Public address is used to identify wallet in all [spark operations](https://teos-docs.coreledger.net/resources/using-the-teos-api/concepts/spark#spark-operations) as a spark sender and spark receiver. Public address is publicly available. Public addresses are created from the private key through a complicated mathematical algorithm. 

A private key is an extremely large number that is used in cryptography, similar to a password. Private keys are used to create digital signatures that can easily be verified, without revealing the private key. Private keys represent final control and ownership of a wallet. Private keys are not transferred or sent in TEOS platform, they are securely kept on your mobile device where you sign the transactions and manage your wallets.
