Crypto QR code
Encode a wallet-ready payment URI for 10 chains. Bitcoin, Litecoin, Bitcoin Cash, and Dogecoin use BIP-21; Ethereum, Polygon, and BNB Smart Chain use EIP-681; Solana uses Solana Pay; Monero and Tron have their own URI schemes. A scan opens the user's wallet with the address and amount pre-filled.

The QR above is a real, scannable example. Scan it with your phone — it does exactly what the label says.
Open the generator with this type pre-filledFree, no signup, runs in your browser. The QR is generated on your device, never sent to a server.
Example address only — replace with your own wallet before printing.
When to use it
Donation QR for a personal site, blog, or open-source project
Print a "scan to tip" card for live events or conferences
Use at a counter for in-person crypto payments
Tips for clean scans
Test the amount field on your own wallet before printing — the URI format and amount unit vary by chain (BTC vs wei vs SOL vs TRX vs XMR)
EVM chains (Ethereum, Polygon, BNB Smart Chain) share the same address format — one 0x... address works across all three, but the QR encodes the chainId so wallets route correctly
Solana Pay and Monero URIs include a free-form memo/recipient_name field; use it for invoice numbers, order IDs, or thank-you messages
For privacy, use a fresh address per QR — chain analytics can de-anonymize reused addresses, especially on transparent ledgers like BTC and ETH
Common questions
Which chains are supported?
Ten chains: Bitcoin, Ethereum, Solana, Polygon, BNB Smart Chain, Litecoin, Bitcoin Cash, Dogecoin, Tron, and Monero. All use the standard URI scheme for that chain so any wallet that supports BIP-21, EIP-681, Solana Pay, the Monero URI, or Tron's payment URI will open correctly.
Which wallets read these QRs?
Bitcoin / Litecoin / BCH / Dogecoin: Electrum, BlueWallet, Muun, Trust. Ethereum / Polygon / BNB: MetaMask, Rainbow, Trust, Coinbase Wallet. Solana: Phantom, Solflare, Backpack. Monero: Monerujo, Cake Wallet, Feather. Tron: TronLink, Trust.
Is the QR anonymous?
The QR itself doesn't leak identity, but every supported chain except Monero has a public ledger. Anyone who sees the address can look up its full transaction history. For real privacy, use Monero.

URL QR code
The most common QR code: turn any web address into a scannable link. Drop the URL into a flyer, business card, or packaging and a single scan opens the page — no typing, no typos, no friction.
Email QR code
Encode a mailto: link that prefills the recipient, subject, and body when scanned. Useful for support addresses, contact forms, and "email me about this" signage.
Menu QR code
Encode a link to a hosted menu, PDF, or web page. The standard for table tents in restaurants since 2020, also great for flyers linking to a multi-page brochure.
