Breez is a Lightning Network client and a hub (routing node) that connects individuals, merchants and Bitcoin exchanges to facilitate instantaneous bitcoin commerce.
Breez mobile app is a non-custodial, trust-minimized solution that runs a Neutrino-based light Bitcoin client. When an individual or a merchant installs the Breez app, a payment channel to the Breez hub is automatically created. This means all entities (or nodes) connected to the Breez hub can easily transact using Lightning Network. Users and merchants can receive Lightning Network payments simply by installing the Breez app.
Since the Breez hub also connects to other Lightning Networks nodes, transactions are not limited to Breez entities, but are spread across the entire network. Breez partners with Bitcoin exchanges to provide fiat conversion services to its users and businesses.
