Key Insights
What is the Cashu protocol?
Cashu is a Layer 2 eCash protocol for Bitcoin that uses blind signatures to enable private, tokenized transactions resembling physical cash, allowing users to transfer satoshis via the Lightning Network without on-chain records. It operates on a mint-wallet model where users exchange Bitcoin for bearer tokens issued by a mint, which merchants can verify and redeem.
How does Numo's tap-to-pay app work with Cashu for Bitcoin payments?
Numo's Android app enables merchants to accept Bitcoin payments via NFC tap-to-pay using Cashu ecash tokens, without extra hardware. Customers tap their NFC-enabled device to send tokens, which the merchant verifies instantly; it supports offline payments that sync later, inventory management, and automatic self-custody with zero fees.
