A Self-Custodial Bitcoin Wallet for Global Payments

We're building an accessible payments app, powered by Bitcoin, to make sending money anywhere as simple, fast, and affordable as it should be.

Why We Exist

Our Mission & Vision

Our Mission

To build a self-custodial Bitcoin and Lightning wallet that gives everyone, regardless of where they live or who they bank with, a fast, affordable way to move money that's always in their control.

Our Vision

A world where sending money across the street or across the globe costs nothing, takes seconds, and requires no extra steps. It feels as familiar as Venmo, but it's open to everyone.

Who We Serve

Anyone who moves money, from splitting dinner with friends to paying remote contractors internationally, and wants a faster, cheaper, and more open alternative to slow, expensive bank transfers.

Our Approach

We build on Bitcoin's open global network and layer familiar, Venmo-simple payments on top, including contacts, gifts, pools, and stablecoins, so anyone can send money worldwide without the learning curve.

The Challenge

Why Global Payments Are Broken

The Problem

The global payments system is fragmented, expensive, and designed around institutions rather than people. If you're sending money to family overseas, paying a freelancer in another country, or splitting a bill with someone on the other side of the world, you run into the same walls:

  1. High fees: Traditional wire transfers and remittance services take 3 to 10% of every transaction, robbing families of billions every year.
  2. Slow settlement: Bank transfers can take days. International wires take even longer. In 2026, that's unacceptable.
  3. Access barriers: Billions of people worldwide lack access to reliable banking infrastructure, locking them out of the global economy entirely.
  4. You're not in control: Banks and apps can freeze accounts, reverse payments, or lock you out at any time. Your money isn't really yours until it clears.

Bitcoin offers a way out: a global, open payment network that anyone with a smartphone can use. But until now, using Bitcoin for everyday payments has been too complex for most people: confusing addresses, expiring invoices, channel management, and a user experience that feels nothing like the apps people already love.

Our Solution

Blitz Wallet is a self-custodial Bitcoin and Lightning wallet built on Spark. We combine the best of modern payments design with the speed and reach of Bitcoin, making it possible for anyone to send money instantly, anywhere in the world, at near-zero cost.

At the core is Spark, a Bitcoin-native Layer 2 that enables instant, self-custodial transactions without the complexity of traditional Lightning. There is no channel management, no inbound liquidity, and no node uptime requirement. On top of that foundation, we've built a suite of features designed to make Bitcoin payments feel as natural as any app you already use:

  • Contact-Based Payments: Send Bitcoin to anyone in your contacts by name, not a cryptic address. Zero fees between Blitz users. No invoices. No QR codes required.
  • Blitz Gifts: Send Bitcoin through a shareable gift link. A recipient who is new to Blitz can create a wallet from the link before claiming it.
  • Payment Pools: Coordinate group payments and collections, powered by Lightning. Split costs, collect contributions, and settle instantly, with no Venmo required.
  • Dollar Goals: Keep a savings target in USDB, dollars on Bitcoin via Spark, and track progress in one place.
  • Accumulation Addresses: Receive USDT or USDC on supported networks and auto-convert it to Bitcoin or USDB.
  • USDB Stablecoin Savings: Hold your balance in USDB, a USD-pegged stablecoin, to avoid Bitcoin price volatility while staying on Bitcoin's rails. Hold 10 or more USDB to earn up to 6% back, paid daily in BTC. Program terms can change, so check the app. Stablecoins carry issuer and platform risk.
  • Stablecoin Integration: Seamlessly swap between Bitcoin and stablecoins to transact in the currency that makes sense for you, without leaving the app.
  • Human-Readable Addresses: Your Blitz address looks like username@blitzwalletapp.com. Send and receive payments as simply as sending an email.

The result is a payments app that feels familiar, works globally, costs almost nothing, and puts you in full control of your money.

A Real-World Example

"During a holiday, my mother wanted to send money for dinner. She sent my brothers $20 via Venmo. For me, she used Blitz Wallet and sent Bitcoin without needing an invoice or prior coordination. Despite not being technical, she found it just as easy as Venmo."

Simplicity Wins

The best payment experience is one you don't have to think about. We obsess over removing every unnecessary step between you and your money.
