🪙 SCASH Wallet

An open-source lightweight wallet for the SCASH blockchain, designed with security and usability in mind. All private keys, mnemonics, and signing operations are performed locally on the client side, never transmitted over the network.

✨ Features

• 🔑 Address Management

  • Generate and import mnemonics
  • Derive addresses using BIP32 / BIP84 paths
  • Strict address format validation

• 💰 Balance & Transactions

  • Query balances and UTXOs by address
  • Build and sign transactions locally
  • Broadcast signed transactions via RPC node
  • Change outputs handled automatically

• 🔒 Security First

  • AES-encrypted local wallet files
  • Password-protected storage (never sent over the network)
  • Signing process can be performed offline, similar to hardware wallets

• ⚡ Tech Stack

  • Frontend: Next.js (React)
  • Backend: Nest.js + Prisma
  • Blockchain Communication: SCASH RPC
  • Encryption: AES for wallet storage

🚀 Getting Started

# Clone the repository
git clone https://github.com/your-org/scash-wallet.git
cd scash-wallet

# Install dependencies
npm install

# Run development server
npm run dev

📖 Usage

1. Create or import a wallet using mnemonic.
2. Query balances and transactions by address.
3. Construct and sign transactions locally (no private keys ever leave the device).
4. Broadcast signed transactions via your own SCASH node.

🛡️ Security Model

• Wallet files are stored locally and encrypted with AES.
• User password is required for decryption and never transmitted.
• Signing happens locally or offline — similar to how hardware wallets work via Bluetooth or USB.
