Free Crypto Wallet QR Code Generator
Bitcoin, ETH, Solana, USDT & Pi

Zero-Error Cryptocurrency Transactions Through Visual Encoding

Cryptocurrency wallet addresses are long alphanumeric strings (for example, Bitcoin addresses with 34 to 62 characters, or Ethereum hex strings with 42 characters). Attempting to manually type or verify these strings on smartphone keyboards carries severe risk: on decentralized blockchains, transactions are irreversible, and a single character mistake can permanently destroy funds. A cryptocurrency QR code eliminates this risk entirely by transmitting the exact wallet address optically into the sender's wallet application.

Supported Chains & URI Specifications

Our generator strictly adheres to established cryptocurrency improvement proposals (BIPs and EIPs) to ensure instant compatibility with Coinbase, Trust Wallet, MetaMask, Phantom, Exodus, Binance, and Pi Browser:

• Bitcoin (BIP 21): bitcoin:1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa?amount=0.025
• Ethereum (EIP 681): ethereum:0x71C...392?value=0.5
• Solana: solana:7NX...4K9?amount=2.5
• Tether USD (USDT): Standardized URI address formatting across TRC20 and ERC20 networks.
• Pi Network: Supports direct receiving addresses for the Pi mobile ecosystem.

Best Practices for Merchant Point of Sale & Invoicing

1. Leave the Amount Field Blank for Open Donations: If accepting tips, donations, or recurring open payments, leave the amount field empty. The sender's wallet will prompt them to enter their preferred donation amount.
2. Specify Fixed Invoicing Amounts: If billing for a specific product or service, enter the exact crypto amount. Scanning the code automatically populates both the destination address and the exact total, preventing underpayments.
3. 100% Client-Side Privacy: Financial privacy is paramount. Unlike online custodial generators, Free QR Code Generator processes your address purely within your browser memory; we never see, log, or transmit your crypto address.
