Create Crypto Payment QR Codes for Free
Generate a BIP-21 payment code for Bitcoin, Bitcoin Cash, Litecoin or Dogecoin, with an optional amount.
Why it works
Why use a crypto payment qr code?
It removes address transcription, which is the step where crypto payments actually go wrong.
Every major wallet supports scanning BIP-21 codes — there's no app or platform lock-in.
A fixed amount removes ambiguity for a set price; leaving it blank suits donations and variable bills.
The code is static, so it keeps working indefinitely regardless of what happens to your account with us.
What it is
What is a Crypto Payment QR Code?
A crypto payment QR code encodes a wallet address using the BIP-21 URI standard, so scanning it opens the payer's wallet app with the address — and optionally the amount and a reference — already filled in. It supports Bitcoin and the chains that share the same scheme: Bitcoin Cash, Litecoin and Dogecoin.
Wallet addresses are long, case-sensitive strings that were never meant to be read by humans, let alone typed by them. Reading one aloud is error-prone, printing one invites transcription mistakes, and unlike a bank transfer there is no recall, no dispute process, and nobody to phone. A mistyped address doesn't bounce — it sends someone else's money into a void.
That's the entire reason payment QR codes exist in crypto, and why every wallet app ships with a scanner. The code removes the only genuinely dangerous step in the process. It's also why this type is static: the wallet reads the address directly off the code, with nothing in between that could alter it.
“A mistyped crypto address doesn't bounce. It sends the money somewhere nobody can retrieve it from.”

Getting started
How to create one, step by step
Pick your coin
Bitcoin, Bitcoin Cash, Litecoin or Dogecoin. These share the BIP-21 URI scheme, so one builder covers all four.
Paste your wallet address
Paste rather than type. Copy it straight from your wallet so there's no chance of a transcription error.
Add an amount and label, if useful
The amount is in whole coins, not satoshis. The label and message show in the payer's wallet as context.
Test with a small amount, then print
Scan your own code and send the smallest practical amount to confirm it arrives before anything goes to print.

Best practices for crypto payment qr codes
The code itself rarely goes wrong — how it's set up and where it's placed is what determines whether people actually use it.
Send a test transaction before printing
The smallest amount your wallet allows is enough. A wrong address is unrecoverable and undiscoverable until someone has already paid — this is the one check that isn't optional.
Leave the amount blank unless the price is genuinely fixed
Crypto prices move. An amount baked into a printed code is correct on the day it's printed and drifting from that point on. For anything but a fixed invoice, let the payer enter it.
Print the first and last few characters underneath
It lets a cautious payer confirm the address in their wallet matches the one you published, which is standard practice among people who move crypto regularly.
Use a fresh address if you care about privacy
A single printed address makes every payment to it publicly linkable on the chain. If that matters for your situation, generate a new code per campaign rather than reusing one forever.
