Question 1

How does a crypto QR code work?

Accepted Answer

The QR code encodes your wallet address (and optionally an amount) using the standard URI scheme for each cryptocurrency (e.g., bitcoin:, ethereum:). When scanned with a compatible wallet app, it pre-fills the recipient address so the sender can confirm and pay.

Question 2

Which cryptocurrencies are supported?

Accepted Answer

You can generate a QR code for any cryptocurrency wallet address — Bitcoin (BTC), Ethereum (ETH), Solana (SOL), Litecoin (LTC), USDT, USDC, and more. Simply paste your address and select the network.

Question 3

Can I include a specific payment amount?

Accepted Answer

Yes. You can optionally set a requested amount that will be pre-filled in the sender's wallet app. This is useful for invoices, donations, and fixed-price sales.

Question 4

Is it safe to share my wallet address via QR code?

Accepted Answer

Sharing a receiving address is safe — it only allows others to send funds to you. Never share your private key or seed phrase. The QR code is generated entirely in your browser and your address is never stored on our servers.

Question 5

Where should I use a crypto QR code?

Accepted Answer

Common use cases include tip jars at events or streams, donation pages for nonprofits, invoices, point-of-sale payments, and printed materials like stickers or posters.
