Pay without channel setup
You do not need to open Lightning channels, manage inbound liquidity, or run a payment node to use Blitz.
A Spark wallet built for payments
Blitz uses Spark for Bitcoin payments so theres no complexity.
Using Spark in Blitz
Everyday Bitcoin payments
Spark is a Bitcoin Layer 2 network. Blitz uses it to connect familiar wallet features with payments, contacts, and Lightning.
Use more than Spark
Blitz also supports Lightning payments and on-chain Bitcoin. The app presents payment details and any applicable fee before you confirm.
Payments with people and businesses
Use contacts, gifts, pools, Nostr Wallet Connect, and point of sale alongside the wallet's Bitcoin payment features.
Know the tradeoffs
Fast payments still have a trust model
Blitz does not store your 12-word seed phrase. Spark operators participate in ordinary Spark state changes, so seed ownership and the ability to move funds during an operator outage are separate questions.
Operators and normal transfers
Operators participate in normal Spark transfers. If they are unavailable or refuse to cooperate, those transfers can be delayed or stop. Read the Spark documentation and Blitz's own security explanation.
Recovery and operator outages
If operators stop signing, Spark’s unilateral exit lets you withdraw to the Bitcoin blockchain without them. Today it’s a command-line process with on-chain fees and timelock waits. Compare the current recovery evidence.
Common questions
Spark wallet questions
What is Spark in Blitz Wallet?
Spark is the Bitcoin Layer 2 network Blitz uses for wallet payments. Blitz also supports Lightning and on-chain Bitcoin.
Do Spark operators take part in payments?
Yes. Spark operators participate in ordinary Spark state changes. If they are unavailable or do not cooperate, normal Spark transfers may be delayed or stop.
Can I move Spark funds if operators are unavailable?
Spark’s unilateral exit lets you withdraw to the Bitcoin blockchain without operators, but today it’s a technical command-line process with on-chain fees and waiting periods, and small balances aren’t worth exiting. Read the security page.
