ChangeNOW is a cryptocurrency exchange service for buying, selling and swapping digital assets. A user selects an exchange pair, sends the source asset to a generated address and receives the target asset in their wallet; the service supports standard and fixed-rate flows, as well as swaps across different blockchains.

In addition to its user-facing exchange, ChangeNOW provides APIs and widgets for integrating exchange functionality into third-party apps, wallets, websites and bots. Its product family also includes NOW Wallet, NOWPayments, NOW Custody, NOWNodes and NOW Token, which is used within the ChangeNOW ecosystem for selected features and partner conditions.
