Transferring digital assets from Binance Chain (formerly Binance Chain, now BNB Beacon Chain) to MEXC Exchange is a common task for traders looking to access different liquidity pools or take advantage of specific trading pairs. While the process appears straightforward, it requires careful attention to network selection and address matching to avoid permanent loss of funds. This guide provides a clear, step-by-step walkthrough for completing the transfer successfully.

First, understand the key difference between Binance Chain (BEP‑2) and Binance Smart Chain (BEP‑20). Binance Chain uses BEP‑2 tokens and operates on a different network than its more popular smart contract counterpart. MEXC supports deposits from both networks, but the address format and memo requirement differ significantly. Always confirm which network your specific token belongs to before initiating any transfer.

Log in to your MEXC account and navigate to the “Assets” section. Select “Deposit” and choose the cryptocurrency you wish to transfer, such as BNB, BUSD, or any other BEP‑2 token. The system will display the deposit address and a required memo (tag). The memo is a unique identifier that MEXC uses to credit the deposit to your account. Copy both the deposit address and the memo to your clipboard or a secure note.

Next, open your Binance account. Go to “Wallet” then “Withdraw.” Select the same cryptocurrency you chose on MEXC. In the withdrawal interface, you will see a network selection dropdown. Here is the most critical step: choose “BNB Beacon Chain (BEP‑2)” not “BNB Smart Chain (BEP‑20)” or any other network. Paste the MEXC deposit address into the recipient address field. Then, paste the memo exactly as copied from MEXC. Without the correct memo, funds may not be credited, and recovery can be time‑consuming.

Double‑check all details: the network, address, memo, and amount. Binance may display a withdrawal fee that varies by token and network load. Confirm the withdrawal. After submission, the transaction will be processed, and you can track its status on the BNB Beacon Chain explorer using the transaction hash provided by Binance.

Wait for network confirmations. Typically, BEP‑2 transactions require around 20–30 confirmations before MEXC credits the funds. Check your MEXC deposit history periodically. Delays can occur during high network traffic or maintenance periods. If the funds do not appear after an hour, contact MEXC support with your transaction hash.

Common pitfalls include selecting the wrong network (e.g., BEP‑20 instead of BEP‑2), omitting the memo, or using an incorrect address format. Always test with a small amount first if you are uncertain. This practice minimizes risk and confirms that the transfer settings are correct before moving larger sums.

By following these steps—choosing the correct network, copying the memo accurately, and verifying every field—you can transfer crypto from Binance Chain to MEXC safely and efficiently. The speed of the transfer depends on network conditions, but with proper preparation, the process typically completes within 10–30 minutes.
