The collapse of the Terra ecosystem in May 2022 led to the creation of two distinct assets: the new Terra LUNA (now known as Terra LUNA) and the old Terra Classic LUNA (often referred to as "old LUNA" or LUNC). For holders of the original LUNA tokens on the Binance Chain (BEP-2 or BEP-20), moving these assets to an exchange for trading or withdrawing them to a personal wallet can be confusing. This guide provides a clear, step-by-step approach to depositing old LUNA to exchanges and withdrawing it safely.

Understanding the Asset: Old LUNA vs. New LUNA
Before any transaction, confirm you are dealing with old LUNA (LUNC or Terra Classic). Most major exchanges, including Binance, have renamed the original token as "Terra Classic" (LUNC). New LUNA (LUNA) is the post-attack governance token. Mistaking one for the other can result in permanent loss of funds. Always double-check the token name and contract address.

Step 1: Identifying Your Old LUNA on Binance Chain
Old LUNA can exist on two types of Binance Chain: Binance Chain (BEP-2) or Binance Smart Chain (BEP-20). Check your wallet (e.g., Trust Wallet, MetaMask, or Binance Chain Wallet) for the token symbol. If it says "LUNA" with the BEP-2 or BEP-20 label, and the contract address matches the Terra Classic address (e.g., 0xbd31... for BEP-20), this is old LUNA.

Step 2: Depositing Old LUNA to an Exchange
1. **Choose a compatible exchange:** Binance, KuCoin, and others support LUNC deposits. Check that the exchange accepts deposits from Binance Chain (not just Terra Chain).
2. **Get the deposit address:** Log into your exchange account, navigate to "Deposit," search for "LUNC" or "Terra Classic," and select the correct network. For BEP-2, select "BEP-2." For BEP-20, select "BSC" or "BEP-20."
3. **Send from your wallet:** In your personal wallet, initiate a transfer. Paste the exchange deposit address. Ensure the network matches exactly. If you send BEP-20 to a BEP-2 address, the funds may be lost.
4. **Wait for confirmations:** BEP-2 transactions typically require 1 confirmation; BEP-20 requires about 12 block confirmations. Do not panic if it takes a few minutes.
5. **Verify receipt:** Check your exchange wallet history. The LUNC balance should appear after sufficient confirmations.

Step 3: Withdrawing Old LUNA from an Exchange
1. **Go to Withdraw:** In your exchange account, find the "Withdraw" section for LUNC.
2. **Select network:** Choose the destination network. If you are sending to a Binance Chain wallet, select BEP-2 or BEP-20. If sending to a Terra Classic wallet (native chain), select "Terra Classic" (this is different from Binance Chain).
3. **Enter address and amount:** Copy the receiving wallet address carefully. Use a small test transfer first if the amount is large.
4. **Confirm and pay fee:** Review the network fee (usually low for BEP-2/BEP-20). Confirm the withdrawal.
5. **Track the transaction:** Use the TxID on a block explorer like BscScan (BEP-20) or Binance Chain Explorer (BEP-2) to monitor progress.

Common Mistakes to Avoid
- **Network mismatch:** Never send BEP-20 tokens to a native Terra Classic address. The tokens will be lost.
- **Memo requirement:** Some exchanges require a "memo" or "destination tag" for BEP-2 deposits. Always include this if prompted; missing it leads to lost funds.
- **Contract address confusion:** Verify the LUNC contract address on Binance Chain. For example, the BEP-20 LUNC contract is 0xbd31… (check official sources). Scammers create fake tokens with similar names.

Security Tips
- Always enable 2FA on your exchange account.
- Use a hardware wallet for long-term storage of LUNC.
- Never share your private keys or seed phrase.
- If migrating from old LUNA to new LUNA, use the official Terra migration tools; do not send tokens to random addresses.

Conclusion
Depositing and withdrawing old LUNA from Binance Chain to an exchange is a straightforward process if you pay attention to network compatibility. Always verify the token type (LUNC/Terra Classic), network (BEP-2 vs BEP-20 vs Terra Classic), and contract addresses. By following these steps carefully, you can securely manage your old LUNA holdings across exchanges and personal wallets. For real-time updates, consult the exchange's support page or the official Terra Classic community announcements.
