# How to Use TokenPocket

### **What is EIP-4527?** <a href="#what-is-eip-4527" id="what-is-eip-4527"></a>

EIP-4527 (Ethereum Improvement Proposal 4527) is a standard designed for the Ethereum ecosystem, aimed at achieving secure and transparent data transfer between offline signers (such as hardware wallets or offline mobile wallets) and watch-only wallets using QR codes. It provides a standardized process and protocol to ensure users can securely sign transactions or data without connecting to the network.

1. Open TokenPocket, click on \[Details], and select \[Link Other Wallet]. Only wallets imported or created using mnemonic phrases can be displayed.

2. The QR code display for connecting wallets requires \[Password Verification]. After verification, you can see the QR code. The interface allows you to view the QR code content. Below is a tutorial for interacting with wallets supporting EIP-4527. Other wallets supporting 4527 have similar interaction methods.

4. The wallet import uses the default display/selection method for sub-wallets. After checking the addresses you need to import, click \[Confirm Import] to see the status of the imported watch-only wallet.

5. When execution is required, a scan interface will pop up after normal operations. This operation is the same as using a cold wallet and watch-only wallet for scanning.
