"What you own is not coins, but private keys."

This statement is not just sentimental, but the truth.
In an era of centralized exchange collapses and rampant phishing links, asset security has shifted from 'optional' to 'a survival essential'.

Today we will clarify 👇


🔐 What is a hot wallet? What is a cold wallet?


🔸 Hot Wallet

Connected to the internet, convenient for use at any time

✅ Advantages:

  • Convenient operation, suitable for daily interactions (DeFi, minting, trading)

  • For example, MetaMask, Fox, Rabby, TokenPocket

    ⚠️ Risk:

  • Once the device is infected or a phishing link is clicked, private keys may be leaked

🔹 Cold Wallet

Offline storage, not connected to the internet

✅ Advantages:

  • Private keys isolated from the network,cannot be attacked remotely

  • For example, Ledger, Trezor, Keystone (hardware wallets)

⚠️ Risk:

  • Cumbersome operations, requires manual signatures

  • Loss of device or mnemonic phrase = impossible to recover permanently

📌 Advice: Never expose large funds directly in browser wallets.

🛡️ How to manage and protect your crypto assets?

✅ Write the mnemonic phrase on physical paper + metal plate to avoid digital storage

✅ Do not randomly click links on mobile devices, recommended dedicated device + hardware isolation

✅ Set a cold wallet PIN + automatic clearing for exceeding limits

✅ Use Fox + Rabby in different scenarios, Rabby supports custom signature audits for better security

✅ Authorization management: Regularly check authorized assets on revoke.cash / Debank and revoke unnecessary contract permissions

🧠 Practical experience: a story of helping a friend recover stolen assets

One time, a friend clicked on a fake mint link, signed a batch authorization, and the hot wallet was instantly cleared of 30,000 U.

He thought 'only pressing transfer would deduct', but didn't realize 'authorization = handing over control of your assets'.

📌 Since then, I taught him:

  • Review the signature before signing

  • Set up a small amount address as a front, do not sign contracts with a large cold wallet

  • Authorize one asset at a time and revoke immediately after use

✅ Security is the prerequisite for long-term success

📋 Momo姐's security checklist (you can check it too):

  • Is the mnemonic phrase only stored offline?

  • Have you set up a cold wallet? Have you made a backup?

  • Have you recently revoked any permissions?

  • Do you know if the current wallet has interacted with a flagged risk address?

  • Do you casually use public WiFi to access your wallet?

🚨 Safety is not 'nothing has happened', but 'knowing in advance how to avoid problems'.
