Spark Wallet | Your Open-Source Lightning Wallet for Bitcoin Payments
Spark Wallet is a powerful, lightweight, and user-friendly wallet built specifically for the Lightning Network, enabling fast, low-cost Bitcoin transactions. Designed as a non-custodial and open-source solution, Spark Wallet provides full control over your funds while supporting instant microtransactions, ideal for daily Bitcoin payments.
As Bitcoin adoption grows, so does the need for scalable solutions. The Lightning Network offers a second-layer protocol that allows users to send and receive BTC instantly with virtually no fees. Spark Wallet makes interacting with the Lightning Network easy, secure, and accessible for both tech-savvy users and beginners.
🔐 What Is Spark Wallet?
Spark Wallet is a front-end interface built for managing a c-lightning node (a lightweight implementation of the Lightning Network). It is not a standalone app like MetaMask or Trust Wallet but rather a client that connects to your own Lightning node, offering a sleek and functional graphical interface.
Spark Wallet allows you to:
- Send and receive Lightning Network payments
- View transaction history and channel status
- Open and manage payment channels
- Monitor your Bitcoin and Lightning balance
By connecting directly to your Lightning node, Spark Wallet ensures you stay in full control of your private keys and funds — no third parties, no custodians.
