What are Ethereum QR Codes?
Ethereum QR codes are scannable codes that contain cryptocurrency payment information. They encode an Ethereum wallet address and optionally include a payment amount, making it easy to receive ETH or ERC-20 tokens without manually typing long addresses.
When scanned by a compatible wallet app, the QR code automatically fills in the recipient address and amount, reducing errors and streamlining the payment process. This is particularly useful for merchants, fundraising, or person-to-person transfers.
Unlike traditional payment QR codes that redirect through servers, Ethereum QR codes follow the EIP-681 standard to create static QR codes that work forever - even if QR Hideout goes offline. All payment data is encoded directly in the QR code itself, with no after-scan ads, no tracking, and no server dependency. Your QR codes remain functional permanently, ensuring uninterrupted crypto payments for years to come.
How to Use Ethereum QR Codes
- •Enter Your Wallet Address: Copy your Ethereum address from your wallet (MetaMask, Trust Wallet, Coinbase Wallet, etc.) and paste it into the generator. The address must start with "0x" and be exactly 42 characters long.
- •Add Amount (Optional): Specify a payment amount in wei (the smallest unit of ETH). For reference, 1 ETH = 10¹⁸ wei. Use an ETH to wei converter if needed.
- •Generate & Download: Click generate to create your QR code. Download as PNG for digital use, SVG for print, or PDF for documentation.
- •Share & Scan: Display your QR code where others can scan it with their mobile wallet apps to send you ETH or tokens.
Why Use QR Hideout for Ethereum QR Codes?

Security Best Practices
- Verify Before Sharing: Always double-check that the QR code contains the correct wallet address before distributing it.
- Test with Small Amount: Before accepting large payments, test with a small transaction to verify everything works correctly.
- Use Fresh Addresses: For privacy, consider generating new wallet addresses for different purposes or customers.
- Protect Your Private Keys: Never include private keys or seed phrases in QR codes. Only share your public address.
- Verify Network: Ensure senders are using the correct network (Ethereum mainnet, not testnets) to avoid lost funds.
Common Mistakes to Avoid
- ✗Typos in Address: One wrong character makes the address invalid. Always copy-paste, never type manually.
- ✗Wrong Network: Using a Bitcoin or other blockchain address format will result in lost funds.
- ✗Incorrect Amount Format: Amounts should be in wei, not ETH. 1 ETH = 1,000,000,000,000,000,000 wei.
- ✗Not Testing First: Always test with a small amount before accepting large payments.
- ✗Sharing Private QR Codes Publicly: Don't post payment QR codes publicly if you want to control who can send you funds.
Technical Details: Understanding EIP-681
Ethereum QR codes follow the EIP-681 standard (Ethereum Improvement Proposal 681), which defines a URL scheme for making Ethereum transaction requests. This standard was created specifically to enable wallet-to-wallet payments via QR codes with deep linking support, eliminating the need for users to manually copy-paste addresses or amounts.
ethereum:<address>[@<chainId>][?value=<amount>]- •address: Ethereum wallet address starting with 0x followed by 40 hexadecimal characters (e.g., 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb)
- •chainId (optional): Network identifier - 1 for Ethereum mainnet, 137 for Polygon, 56 for Binance Smart Chain, 42161 for Arbitrum, etc.
- •value (optional): Payment amount in wei (1 ETH = 1,000,000,000,000,000,000 wei). Use wei calculators to convert from ETH.
Compatible wallets like MetaMask, Trust Wallet, Coinbase Wallet, Rainbow, and Argent automatically parse this URI format when scanning the QR code, pre-filling transaction details for the user to confirm. This creates a seamless payment experience with minimal friction and maximum security.
Real-World Use Cases for Ethereum QR Codes
Physical Crypto Stores & ATMs
Crypto-friendly coffee shops, retail stores, and Bitcoin ATMs display Ethereum QR codes at checkout. Customers scan the code with their mobile wallet, confirm the pre-filled amount, and complete payment in seconds - faster than credit card chip readers. Popular in crypto hubs like Miami, Austin, and Singapore where Web3 adoption is high.
NFT Art Galleries & Digital Exhibitions
NFT artists display Ethereum QR codes next to physical prints of their digital art at galleries and exhibitions. Collectors scan to purchase the NFT directly, with the ETH payment amount pre-filled. This bridges physical and digital art experiences, making NFT purchases as simple as buying traditional art.
Conference Tickets & Event Payments
Blockchain conferences like ETHDenver and Consensus accept Ethereum QR code payments for tickets, merchandise, and food vendors. Attendees scan QR codes on event apps or physical kiosks, eliminating the need for traditional payment infrastructure. Instant settlement means vendors receive funds immediately without waiting days for credit card processing.
Freelance Invoicing & International Payments
Developers, designers, and consultants working with international clients include Ethereum QR codes on invoices. Clients in any country can pay instantly without dealing with wire transfer fees ($25-50 per transaction), currency conversion fees (3-5%), or multi-day settlement delays. Freelancers receive payment in minutes instead of 3-7 business days.
Open Source & Web3 Project Funding
GitHub repositories, Web3 documentation sites, and open-source projects display Ethereum donation QR codes to fund development. Supporters worldwide can contribute crypto without geographic restrictions imposed by traditional payment platforms like PayPal or Patreon. Projects like Ethereum research, Layer 2 protocols, and developer tools receive millions in funding via QR code donations.

Frequently Asked Questions
Does QR Hideout show ads after scanning?
Never. QR Hideout generates static QR codes that encode your Ethereum address directly into the code—no ads, no redirects, no tracking. When someone scans your QR code, their wallet app opens immediately with your address pre-filled. Zero interruptions, zero data collection.
What's the difference between static and dynamic QR codes?
Static QR codes encode your Ethereum address directly into the code itself—they work forever, even offline. Dynamic QR codes require a server redirect, where competitors often show ads or track wallet addresses and transaction amounts. Our static approach ensures your crypto QR codes remain functional permanently, with complete financial privacy.
Can QR codes open crypto wallet apps directly?
Yes! QR Hideout supports Ethereum deep links using the ethereum: URI scheme. When scanned, the QR code can open wallets like MetaMask, Trust Wallet, Coinbase Wallet, and Rainbow directly with your address and optional payment amount pre-filled—no manual copy-pasting required.
Will my Ethereum QR code stop working if QR Hideout goes offline?
No. Our static QR codes encode your complete Ethereum address directly—they'll work forever, even if our website goes offline. The QR code contains the full 0x... address or ethereum: deep link, so there's no server dependency. Your payment address is permanent.
Can I use the same QR code for Bitcoin and Ethereum?
No. Ethereum and Bitcoin use completely different address formats and blockchain networks. An Ethereum address starts with 0x (42 characters), while Bitcoin addresses start with 1, 3, or bc1. You must create separate QR codes for each cryptocurrency. Sending to the wrong address type will result in permanent loss of funds.
Can I include a specific payment amount in my Ethereum QR code?
Yes! When using the ethereum: deep link format, you can include an optional payment amount in ETH (e.g., ethereum:0xAddress?value=1.5e18 for 1.5 ETH). Note that the value must be specified in wei (smallest unit of ETH, where 1 ETH = 10^18 wei). Most wallet apps will display this as the suggested amount.
Are Ethereum QR codes safe to share publicly?
Yes, but with awareness. Your Ethereum address is public information on the blockchain—anyone can see your transaction history and balance using block explorers like Etherscan. Sharing a QR code of your address is safe for receiving payments, but be aware that all transactions to/from that address are publicly visible. For enhanced privacy, consider using a fresh address for each transaction.
What's the difference between an Ethereum address and an ENS name?
An Ethereum address is the 42-character hexadecimal identifier (e.g., 0x742d...). An ENS (Ethereum Name Service) name is a human-readable alias (e.g., vitalik.eth) that resolves to an Ethereum address. Both can be encoded in QR codes, but ENS names require wallet support for resolution. For maximum compatibility, use the full 0x address.
Can I use Ethereum QR codes for ERC-20 tokens like USDT or USDC?
Yes! ERC-20 tokens (USDT, USDC, DAI, LINK, etc.) all use the same Ethereum address format. A single Ethereum address can receive ETH and any ERC-20 token. However, the basic QR code only specifies the receiving address—the sender must manually select which token to send. For advanced use cases, you can encode token contract addresses in the deep link, but wallet support varies.
How do I verify my Ethereum address is correctly encoded in the QR code?
Always test before sharing! Scan the QR code with your own wallet app and verify the address matches exactly (all 42 characters including the 0x prefix). Ethereum addresses are case-sensitive for checksum validation—one wrong character can send funds to the wrong address permanently. We recommend doing a small test transaction first before sharing QR codes for large amounts.
