Question 1

How do I create a USDT QR code?

Accepted Answer

Choose the USDT TRC20 or USDT ERC20 link type, paste your wallet address, and optionally set an amount. The generator builds the correct token-transfer link, so compatible wallets open a pre-filled payment when scanned.

Question 2

Which cryptocurrencies are supported?

Accepted Answer

There are ready-made options for Bitcoin, Ethereum, USDT (TRC20 and ERC20), and USDC, plus a custom protocol mode for any other coin that uses address-based payment links.

Question 3

Is it safe to share my wallet address as a QR code?

Accepted Answer

Yes. The QR code contains only your public wallet address and the optional amount — data that is safe to share. It is generated locally in your browser and never uploaded to a server.

Question 4

Can I set a fixed payment amount?

Accepted Answer

Yes. Add an optional amount when creating the code and supported wallets will pre-fill it for the sender. Leave it empty to let the sender choose the amount.
