How to Recover Missing USDT After Importing Wallet with Mnemonic Phrase on Android

Understanding the Issue

When switching from an iPhone to an Android device and importing your Ethereum wallet using the mnemonic phrase, you encountered two critical problems:

1. Your USDT balance shows 0 on both devices
2. An unauthorized ETH transaction occurred from your wallet

Initial Steps to Diagnose the Problem

1. Check Transaction History:

   • Navigate to your USDT transaction records. If outgoing transfers exist without your authorization, your wallet may be compromised.
   • If no outgoing transfers appear but USDT is visible, try switching nodes (Wallet Homepage > Top-left Corner > Select a Low-Latency Node).

2. Suspicious ETH Transaction:

   • Your ETH deposit from OKX at 21:28 remained "pending," while an unauthorized transfer of 0.01385 ETH occurred at 22:07 to an unknown address.

   • Transaction Hashes:

     • Deposit: 0x96e4a97c343abeaa3fa891a6c1f6cd0bd32cb448d5d79163ecdcd6f7d12080cb
     • Unauthorized Withdrawal: 0x10fcd1f6abe2f59f0718c87d44d01cffe64e4f90bfd791ea7ec1b73ec8f5a69c

Confirming Wallet Compromise

• Key Indicators:

  • Your Ethereum address (0x337f8C315f108022dD0aE5B3CAEc68DB612E8Dee) shows no historical USDT transactions on-chain.
  • Unauthorized ETH transfer confirms private key/mnemonic phrase leakage.

👉 Secure Your Crypto with a Hardware Wallet

Critical Actions to Take

1. Verify Wallet Authenticity:

   • Download TokenPocket only from the official site: tokenpocket.pro.
   • Test installation: If the app cannot be overwritten, it’s counterfeit.

2. Identify Leak Sources:

   • Shared mnemonic with third parties (e.g., friends, apps).
   • Screenshots/photos of the phrase stored in insecure locations.

⚠️ Warning:

• Compromised wallets cannot be recovered.
• Blockchain transactions are irreversible.
• Create a new wallet immediately and transfer remaining funds.

Addressing USDT Discrepancies

Possible Scenarios

1. Incorrect Mnemonic Import:

   • The imported phrase may belong to a different wallet address. Cross-check the receiving address for your 4,300 USDT deposit.

2. No On-Chain Records:

   • If USDT transactions are missing entirely, the funds might have been sent to another address. Request the sender’s transaction details for verification.

FAQ

Q1: Can someone change my mnemonic phrase and steal my USDT?
A: No. Each mnemonic phrase corresponds to a unique address. All transactions are permanently recorded on-chain.

Q2: Why does my wallet show 0 USDT despite earlier screenshots?
A: The displayed balance likely belongs to a different wallet address. Verify the deposit transaction’s destination address.

Q3: How do I prevent future theft?
A: Use a hardware wallet like KeyPal for secure offline storage: KEYPAL Store.

Final Recommendations

1. Stop using the compromised wallet.
2. Trace the 4,300 USDT sender’s transaction to confirm the receiving address.
3. Migrate funds to a newly created, secure wallet.
4. Enable transaction alerts for future monitoring.
