Cryptocurrency QR codes are one of those use cases where the alternative — typing a 42-character address by hand — is so bad that the QR code feels like a superpower. Scan, confirm amount, send. No transcription errors, no "wait, was that a 0 or an O," no accidental typo that sends your rent payment into the void forever.
This guide covers how to create a cryptocurrency QR code on QuicklyGenerateQR — for Bitcoin, Ethereum, and Litecoin — and how to use them safely.
Why cryptocurrency QR codes matter
Cryptocurrency addresses are designed to be impossible to guess and extremely inconvenient to transcribe. A typical Bitcoin address is 26-35 characters of mixed-case alphanumeric data with no obvious pattern. Ethereum addresses are 42 characters of hexadecimal. Litecoin is similar.
Typing one wrong character doesn't usually produce an invalid address — many invalid strings still pass the checksum. And because cryptocurrency transactions are irreversible, a typo can mean permanent loss of funds.
A QR code eliminates the typing entirely. The receiving wallet gets the full address, checksum intact, with zero room for human error. This is why every major wallet app has had QR scanning built in since roughly 2013.
The formats QuicklyGenerateQR supports
Bitcoin (BTC)
Uses the bitcoin: URI scheme. Supports optional amount pre-fill. When scanned, opens a new-transaction screen in the receiving wallet with the address filled in.
Ethereum (ETH)
Uses the ethereum: URI scheme. Same amount pre-fill support. Compatible with MetaMask, Trust Wallet, and every major Ethereum wallet on iOS and Android.
Litecoin (LTC)
Uses the litecoin: URI scheme. Identical to Bitcoin in behavior — same wallet integration, same amount pre-fill, same irreversibility caveat.
The encoded string for a simple Bitcoin address looks like this:
bitcoin:bc1qw508d6qejxtdg4y5r3zarvary0c5xw7kv8f3t4
And with an amount pre-filled:
bitcoin:bc1qw508d6qejxtdg4y5r3zarvary0c5xw7kv8f3t4?amount=0.005
The five-step workflow
Get your wallet address
Copy your receiving address from your wallet. Every wallet app has a "Receive" button. Use the correct address for the currency you want — sending BTC to an ETH address is catastrophic and irreversible. Triple-check before proceeding.
Open the generator and pick Crypto
Head to the free QR code generator and select Crypto from the type selector.
Fill in the form
Pick Bitcoin, Ethereum, or Litecoin from the dropdown. Paste your wallet address. Optionally add an amount — include it for invoices with a specific price, leave it blank for general tip jars and donations where the sender decides.
Customize the design
Match the code to the context. A tip jar at a coffee shop might use brand colors; a conference speaker's donation code might be minimal black-on-white. Add a logo if you have one — error correction auto-bumps to preserve scannability.
Download and deploy
Export as SVG for print or PNG for digital. Common placements: tip jars, conference booths, streamer overlays, merchant payment terminals, crowdfunding materials, invoices.

Free, static, no account required. Your wallet address is encoded directly into the code — nothing is ever sent to our servers.
Safety: the seven rules that protect your wallet
Cryptocurrency transactions are irreversible. That fact alone shapes every safety recommendation.
1. Verify the printed code before deploying
Before you print or post a crypto QR code in public, scan it with your own phone and verify the address shown. Compare it character-by-character against your wallet address. Five seconds of work that prevents catastrophic misconfiguration.
2. Watch for sticker-over-legit scams
The most common real-world crypto QR scam is a criminal placing a sticker over a legitimate donation code — at a parking meter, charity booth, or merchant terminal — with their own wallet instead. Laminate public codes so stickers can't be applied. Inspect periodically.
3. Never scan unsolicited crypto QR codes
The FBI has warned about unsolicited packages containing QR codes used for fraud. If someone sends you a QR code out of the blue in a "verification," "account recovery," or "investment" context — don't scan it.
4. Confirm the currency prefix
A scanner shows you the full encoded URI before opening your wallet. Check that it starts with the expected prefix (bitcoin:, ethereum:, litecoin:). A mismatched prefix is an immediate red flag.
5. Verify first and last characters of the address
When your wallet shows the decoded address, don't just hit "send." Verify the first 6 and last 6 characters match your expected recipient. Clipboard-rewriting malware is real.
6. Send a small test transaction first
For any first-time payment to an address, send a small amount first, confirm it arrives, then send the full amount. The extra fee is cheap insurance against a mistake that can't be undone.
7. Don't hardcode high-value amounts
If you print a static QR code with a hardcoded amount, that amount is baked in forever. For high-value transactions, generate fresh codes each time. For ongoing tips, leave the amount blank and let the sender decide.
What about other cryptocurrencies?
QuicklyGenerateQR currently supports Bitcoin, Ethereum, and Litecoin directly. For other cryptocurrencies (Monero, Dogecoin, Solana, etc.), you can often encode the receiving address as a plain Text QR code — many wallet apps will still recognize and import the address if scanned. The trade-off is that you lose URI scheme features like pre-filled amounts, and some wallets won't accept plain text.
Safer workaround: generate a URL QR code pointing at a web page you control that displays the address. Less elegant, but it works for any cryptocurrency.
