Crypto Payment QR Code Generator — Secure Digital Asset Transfers
Accept cryptocurrency payments and tips with absolute precision using Utilvo's free Crypto QR code generator. Create instant wallet barcodes for Bitcoin (BTC), Ethereum (ETH), Solana (SOL), USDT, Litecoin (LTC), and custom tokens.
Typing hexadecimal wallet addresses manually is dangerous—a single typo or clipboard hijack can result in permanent loss of funds. A crypto QR code encodes your exact public key and optional requested amount for 1-tap wallet scanning.
Designed for web3 merchants, crypto freelancers, charity donation drives, and point-of-sale retail terminals.

Can I encode payment amounts into the crypto QR code?
Yes, you can specify optional request amounts (e.g. bitcoin:1Address?amount=0.05) so wallet apps automatically pre-fill payment totals.
What is the BIP-21 URI format used in Bitcoin and crypto QR codes?
