Spend in BTC, replace from dollars

When you spend Bitcoin, Blitz takes the same amount from your USDB balance, and buys back Bitcoin for you.

How it works

What happens after you pay

You spend Bitcoin

Send to a contact, a gift, on-chain, Stablecoins or a QR code.

Blitz buys back Bitcoin

Blitz takes the same dollar amount from your USDB balance and swaps it for Bitcoin.

If your dollar balance is low

If you have less in dollars than you spent, Blitz uses your full dollar balance instead. If the amount is under $1, Blitz skips the swap.

Spent	Dollar balance	What happens
$5 in BTC	$20	Swaps $5 for BTC
$20 in BTC	$10	Swaps your full $10 for BTC
$0.50 in BTC	$20	No swap. Under $1

Tax note: Selling or swapping BTC may be a taxable event in some countries, including the United States. Keep your transaction records and ask a qualified local tax professional how the rule applies to you.

Why use it

Spend without lowering your Bitcoin balance

Keep your Bitcoin amount

Spend when you need to. Blitz refills the same amount from dollars so your Bitcoin balance stays steady.

Turn it on once

You do not need to do anything for each payment. Turn it off whenever you want.

Try it with your next payment

Turn on Spend and Replace and send $5 in Bitcoin. Blitz will use dollars to buy back the same amount.
