Balances

The private.user.balances feed provides you with real-time updates on changes to your account balances, including Web3 wallet balances updates.

Updates reflect your balances inclusive of completed, partially completed, or pending transactions, orders, and transfers. For example, a given balance update does reflect outstanding and/or partially filled orders.
