Depositing old LUNA tokens from the Binance Chain (BEP-2) to a supported exchange can be a confusing process, especially after the Terra ecosystem collapse and the subsequent chain migration. This guide provides a clear, step-by-step method to safely move your legacy LUNA tokens to a compatible exchange wallet.

First, understand the difference between "old LUNA" (also known as Terra Classic LUNA or LUNC) and the new LUNA (LUNA 2.0). Old LUNA refers to the original Terra tokens that existed before the network upgrade in May 2022. These tokens still exist on the Terra Classic chain, but many exchanges now list them under the ticker LUNC. Your Binance Chain wallet likely holds BEP-2 version of LUNC, which is wrapped or pegged to the original Terra Classic token.

To proceed, choose an exchange that supports both BEP-2 deposits and LUNC trading pairs. Binance is the most straightforward option because it directly handles BEP-2 assets. If you are using a different exchange like KuCoin or Kraken, confirm they accept BEP-2 LUNC deposits—many only accept the native Terra Classic (LUNC) over the Cosmos IBC protocol, not the Binance Chain variant.

Once you have selected an exchange, open the deposit section and search for "LUNC" or "LUNA Classic." Copy the deposit address and ensure you select the correct network. If the exchange offers multiple options, choose BEP-2 (also sometimes labeled as "BNB Beacon Chain" or "Binance Chain"). Do not select BEP-20 (Binance Smart Chain) or the native Terra network unless you are certain that is what you have.

Next, open your Binance Chain wallet (e.g., Trust Wallet, MetaMask configured for BSC, or a Binance Chain extension wallet). Navigate to your old LUNA token balance. Click "Send" or "Withdraw." Paste the deposit address from the exchange exactly as copied. Double-check the address for accuracy: BEP-2 addresses typically start with "bnb1" and are longer than Ethereum addresses.

Enter the amount you wish to deposit. Be aware that BEP-2 transactions have negligible fees (often just 0.0001 BNB) but require a small amount of BNB balance in your wallet to cover gas fees. If you do not have BNB, you cannot send the transaction. Always send a small test transaction first, especially with older or less liquid tokens, to confirm the exchange credits the deposit correctly.

After sending, you will see the transaction status in your wallet. Wait for the exchange to confirm the deposit. This can take 1 to 5 minutes on Binance Chain. Once confirmed, your old LUNA will appear as LUNC in your exchange wallet. You can then trade, swap, or hold it. If the token does not appear, contact the exchange support with the transaction hash (TXID) for assistance.

Important warnings: Never deposit old LUNA directly to an exchange address that only supports the new LUNA (LUNA 2.0). Doing so could result in permanent loss. Always verify the token ticker (LUNC vs. LUNA) and network (BEP-2 vs. native Terra Classic vs. BEP-20) before confirming the transaction. Additionally, some exchanges have delisted or suspended deposits for old LUNA variants—check the exchange's announcements before initiating a transfer.

By following these steps—choosing the correct exchange, selecting BEP-2 network, funding your wallet with BNB, and performing a test transaction—you can safely deposit your old LUNA from Binance Chain without losing funds during the process.
