Ecash App

Ecash App is an open source, transparent Fedimint wallet. It is an easy to use payments wallet, but allows for power users to access the full suite of Fedimint features. It works with every federation. Join a federation, hold ecash notes on your device, and pay. There is no account to create and no sign-up. WHAT YOU CAN DO • Pay and receive over Lightning — scan a QR code, paste an invoice, or open an LNURL link. • Claim a Lightning Address, so anyone can pay you at a name that reads like an email address. • Send and receive on-chain bitcoin, and watch deposits as they confirm. • Hand ecash to someone directly, as a string of text, with no payment network in between. • Discover federations over Nostr, and preview one before you join it. • Keep balances in several federations at once and switch between them. • Find nearby merchants that accept bitcoin, using BTC Map. • Sync your friend's payment information using Nostr • Lock the app with a PIN. NOTHING HIDDEN • Every fee, itemized, before you confirm a payment. • The Lightning gateways a federation has registered, and the one your payment will route through. • The on-chain UTXOs the federation holds. • The denominations of the ecash notes making up your balance. BACKUP AND RECOVERY Your wallet comes from a standard seed phrase. Write it down once, and you can restore your balances on another device. Recovery walks through each federation and restores what it finds.
