✦ What makes this different?

Unlike generic QR makers that only encode the address, this generator builds a true BIP21 payment URI: bitcoin:address?amount=&label=&message=. That means wallets automatically populate amount, avoid typing mistakes, show your label, and log your message. We added strict Bitcoin address validation (Base58Check and Bech32 character set), 8-decimal amount precision, and URL-safe encoding for label/message. All generation happens client-side. No server, no tracking — your private payment data never leaves device. Built for YellowNex with Bitcoin Orange #F7931A to #FF5F00 luxury gradient.
