# Creating QR Codes
The main feature of the Blockwell Wallet system is the ability to create QR Codes to perform any transaction on the Ethereum blockchain. Anyone can then use them on any device with a web browser to interact with the blockchain.
Creating QR Codes is currently free and unrestricted, you can simply go to the QR Creator on the Blockwell Wallet website and make one.
# Regarding contracts
Blockwell Wallet needs some information on the contract itself before QR Codes can be created. Most contracts will be added automatically, but if you run into issues with a contract not being found, contact us on Telegram and we can get your contract added to the system.
