How Crypto QR Codes Work
Cryptocurrency QR codes encode your wallet address in a standard URI format recognized by wallet apps. For Bitcoin, this is BIP21 (bitcoin:address?amount=X). For Ethereum, it's EIP-681 (ethereum:address). When someone scans the QR code with their crypto wallet, it pre-fills the recipient address, amount, and label — reducing errors from manual address entry.
We support four cryptocurrencies: Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), and Bitcoin Cash (BCH). Each uses the standard URI format recognized by major wallets like MetaMask, Trust Wallet, Coinbase Wallet, and others.
How to Create a Crypto QR Code
- Select your cryptocurrency — Bitcoin, Ethereum, Litecoin, or Bitcoin Cash.
- Paste your wallet address — the receiving address for payments.
- Set amount and label (optional) — pre-fill a specific amount and a human-readable label like "Donation" or "Invoice #123".
- Download your QR code and share it for receiving payments.
Where to Use Crypto QR Codes
- Accepting payments — at physical locations that accept cryptocurrency
- Donations — open-source projects, charities, and content creators accepting crypto
- Invoices — include a QR code on invoices for crypto-paying clients
- Point of sale — retail checkout screens for crypto payments
- Tip jars — digital tip jars for streamers, artists, and performers
Security Note
Always double-check your wallet address before generating the QR code. Cryptocurrency transactions are irreversible. Test with a small amount first if using the QR code for payments. Your wallet address is encoded in the QR image and is never sent to our servers.
