Send and receive Bitcoin over the Lightning Network, register your own Lightning Address, and stay in full control of your keys — they never leave your device. KEY FEATURES • Self-custodial — your 12-word seed phrase never leaves your phone. We never see it, never store it, and never hold your funds. • Lightning fast — pay anyone with Lightning invoices and Lightning Addresses in seconds. • Lightning Address — receive payments at your personal username@zaparc.app address. • On-chain Bitcoin — send and receive regular Bitcoin transactions when you need to. • Multi-wallet — manage several seeds and sub-wallets from one app. • Encrypted Google Drive backup — sync your seed backup to your private Drive folder. • Biometric unlock — Face ID or Touch ID protects every session. • QR scanner — scan Bitcoin and Lightning invoices with auto-detection. WHY ZAPARC ZapArc is for people who want Bitcoin to feel like cash. Lightning gives you instant, near-free settlement. Self-custody means there is no company that can freeze your account or lose your funds in a hack. You are the bank. IMPORTANT ZapArc is a self-custodial wallet. If you lose your device and your seed phrase backup, your funds will be permanently inaccessible. Always write down your 12-word recovery phrase and keep it somewhere safe before depositing meaningful funds. Bitcoin and Lightning transactions are final and irreversible once confirmed.

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.
