Crypto QR code generator
Pick the network, paste your address, set an amount if you like. A scan opens the payer’s wallet with everything filled in.
What a Crypto code does
A crypto code carries a payment URI — the network, your address and an optional amount. Wallet apps read it and prefill the payment for the payer to confirm.
The address is checked against the network’s format before the code is drawn, so a typo does not end up in print.

QuestionsCrypto QR code questions
- Is the crypto QR code generator free?
- Yes. Choose the network, enter the address, and download a PNG or SVG. No account needed.
- Which networks are supported?
- Bitcoin, Ethereum, USDT on Ethereum (ERC-20) and Tron (TRC-20), Litecoin and Solana.
- Does Dotwick see my wallet address?
- No. The code is generated in your browser and nothing is sent to us.
- Why can’t a crypto code be dynamic?
- Wallets read the payment details straight from the code, not through a link. A static code also means nobody can change where a printed code sends money.
