Private Ecash
Cashu uses Chaumian blind signatures to create Bitcoin-backed ecash tokens that preserve privacy. Transactions are off-chain and don't reveal any information about the sender or recipient.
Just Cashu
Cashu Dev Kit focuses on implementing the Cashu protocol correctly. You choose your wallet, mint integration, and application features with our toolkit of best practices.
Fast Payments
Cashu transactions happen off-chain, enabling instant payments with no waiting for confirmations. Perfect for quick, everyday transactions when you need speed and convenience.
