What issues does offline verification address first?

Computers and mobile devices may display a replaced (malicious) address; a hardware wallet screen provides an independent channel for verification. It confirms the deposit address generated by the device based on its own internal wallet data. However, it cannot automatically determine whether the sending platform supports the specific network, nor can it guarantee that the payment will actually be sent. Before relying on screen verification, ensure that the source of the hardware wallet, its initialization, and its backup process are trustworthy; otherwise, the information displayed on the screen could be linked to an incorrect or compromised wallet.

Do Not Rely Solely on QR Codes

A QR code is merely a data carrier—it could encode an address, a payment request, or a link. After scanning, always check the decoded network, address, and any additional parameters, and compare them segment-by-segment against the text shown on your hardware wallet’s screen. Do not simply check the first and last few characters; malicious addresses are often crafted to look deceptively similar to legitimate ones. If the information displayed by the software differs from that on the hardware device, stop immediately and investigate the device, the connection, and the application. Never choose the one that simply "looks more familiar."

Verify Networks and Assets Separately

The same address format may be used across multiple compatible networks, but this does not mean that every service supports all of them. Both the sender and the recipient should independently verify the asset, the blockchain network, the token contract address, and whether a memo (or reference note) is required. Bitcoin mainnet, testnets, and various compatible chains are not interchangeable. While a hardware wallet can confirm a specific address, this does not mean that a platform will automatically rectify withdrawals sent to the wrong network.

The Purpose and Limitations of Small-Amount Test Transactions

Once the path is confirmed and the costs are acceptable, a small-amount test transaction can help verify that funds actually arrive. Upon receipt, confirm the asset and the network using a trusted wallet and a blockchain explorer—do not rely solely on push notifications. A successful test does not guarantee that future large-value transfers will be free from delays, account risk controls, or service changes. Always verify each subsequent transaction; do not assume that a previously saved address will remain safe indefinitely.

Protecting Privacy When Sharing Receiving Information

A receiving address is not a private key, but disclosing it may reveal transaction history or clues about your balance. Do not include your full device management interface, extended public keys (xpubs), or recovery information in screenshots or tutorials. When collaborating with others, provide only the information necessary to receive the payment, and clearly specify the network. If anyone requests your seed phrase, device PIN, or private key under the guise of "verifying an address," be aware that this is not a legitimate part of the payment verification process.

Maintaining Your Own Verification Records

Keep records of your wallet accounts, derivation methods, the date an address was generated, the network, the asset, and the verification channels used. After a test transaction, save the transaction ID and proof of receipt; store sensitive information separately and securely. If you update your device firmware or recover an account, re-verify your addresses—do not rely solely on old screenshots.
