# Create a wallet

This endpoint creates a new wallet for the current user. Each TEOS platform user can have one or more wallets. Wallets are used to store and manage sparks of assets owned by a user.

Each wallet consists of a public address and a private key:

* The public address identifies the wallet in all spark operations.
* The private key, securely stored on the user’s device, is used to sign transactions.

TEOS API consumers can create a wallet to securely manage the sparks of assets owned by a TEOS user.
