01What you bought

SuperWallet is a multi-chain, non-custodial crypto wallet written in Flutter, with a Flutter web admin panel and a Firebase backend. Your users keep their own keys on their own phones. You, the operator, run the app from the admin panel: branding, chains, tokens, dApps, feature switches, push notifications, the swap fee and PRO pricing.

Safe defaults in 1.1.0

A fresh install charges no fee: the swap fee is off, every fee wallet is empty, and the fee can never be set above 2 % (200 bps). The package contains no Firebase settings, no admin address and no demo login of anyone else. You connect your own project and turn on what you need.

Part	Folder	What it is
Wallet app	`crypto_wallet/`	The app your users install. Flutter for iOS, Android, web and macOS.
Admin panel	`crypto_wallet_admin/`	Your control centre in the browser. Flutter web.
Backend	`crypto_wallet/functions/`, `firestore.rules`, `remoteconfig.template.json`	Firebase: sign-in, database, Remote Config, push and 30 Cloud Functions (Node.js 22, TypeScript).

Keys stay on the device

Seed phrases and private keys are created and stored on the user's device (iOS Keychain, Android Keystore). They are never sent to Firebase or to you. A browser has no Keychain, so in the web build the user sets a vault passphrase that encrypts the keys in that browser (how it works).

You provide

Your own Firebase project (Blaze plan), a domain and hosting if you want one, Apple and Google developer accounts, third-party API keys (0x, 1inch, Reown and others) and the network fees your users pay. None of these are part of the purchase.

04Try it before you install

Two public demos show the product with sample data:

Wallet (web build): project-3c5ee.web.app — create a throwaway wallet in the browser.
Admin panel: super-wallet-admin-demo.web.app — press Open Client Demo Workspace. Changes stay in your browser.

The admin demo is a separate build made with a demo switch. The admin panel you build from the package has no demo login and no default password (Deployment).
