⚡️ Thanks for the feedback, I will make some supplements and corrections——

1️⃣The security chip is the core of the hardware wallet. You must choose a hardware wallet with a security chip; it is much better than other hardware wallets without security chips; consult yourself when buying, ask more questions and read more!

2️⃣Ledger has also been cracked, not as I said; I heard that someone has directly flashed the Snake firmware to Ledger;

3️⃣ Smart contract authorization will not actually leak the private key; it is just that the authorization is transferred away;

4️⃣ Buy new instead of old. Hardware wallets should be replaced at least two years later. The hardware and chips will be updated. For example, the security chip of the new version of Onekey has been upgraded by one level;

5️⃣The key is that the wallet hardware cannot be lost. Once lost, take the private key immediately and use the backup to transfer the coins.
