Making Bitcoin Simple for Everyone

The Problem

Bitcoin faces a major usability challenge for everyday payments. The current system relies heavily on complex QR codes and addresses, creating friction for users. This stems from two key issues:

1. Finality of payments – Bitcoin transactions are irreversible, so errors in entering addresses can lead to permanent loss of funds.
2. Complexity of addresses – Bitcoin addresses and Lightning invoices are long, difficult to read, and intimidating for newcomers.

While QR codes help mitigate these risks, they also create usability friction. Traditional payment networks use simple identifiers like usernames or phone numbers, making payments seamless. Bitcoin, in contrast, often feels like a step backward in user experience.

The Lightning Network introduces additional technical quirks:

• Lightning Network channel capacity – Users can only receive payments if their channel has enough inbound liquidity.
• Invoice limitations – Lightning invoices expire and can only be used once.
• Node uptime – Lightning nodes must remain online to send and receive payments.

These constraints require users to understand the underlying protocol before they can effectively use Bitcoin, creating a significant barrier to adoption.

Our Solution

Blitz Wallet simplifies Bitcoin payments by integrating Spark, a Bitcoin-native Layer 2 network that enables instant, low-friction, self-custodial transactions without Lightning's complexity.

Unlike traditional Lightning wallets, Spark doesn't require users to manage channels or maintain inbound liquidity. That means you can receive payments instantly without being online or having to set up anything in advance. This removes one of the biggest hurdles in using Lightning for everyday payments.

Spark also allows Blitz to introduce human-readable addresses like username@domain.com, making sending Bitcoin feel as familiar as sending an email. These LNURL addresses replace complex invoices and QR codes with simple, reusable identities—making Bitcoin more accessible for everyone.

With Spark, Blitz Wallet becomes the easiest way to send, receive, and manage Bitcoin: instant payments, no node setup, no channel balancing, and full self-custody. It's the bridge between the power of Lightning and the simplicity users expect from modern apps.
