Does OKX Require a Memo for XLM Deposits?

When depositing XLM on OKX, you need to fill in the Memo, provided you are using the standard address format assigned by the exchange. If the Memo is not correctly filled in, the funds will not be credited normally. The Memo is a key identifier used by the exchange to distinguish users and complete the crediting. Below is a complete explanation and the steps.

Prerequisites

1. You are logged into your OKX account and have navigated to the XLM deposit page.
2. You have obtained the XLM deposit address and Memo number generated by OKX.
3. The wallet you use to hold XLM supports the Memo field (most Stellar wallets support this).

Step 1: Confirm Whether Your XLM Deposit Requires a Memo

Log in to OKX, go to [Assets] → [Deposit], search for XLM and select the Stellar network. The page will display two things:

• Deposit address: a string starting with G
• Memo: a string of digits

Case A: The page displays both an address and a Memo

This means a Memo is required for your XLM deposit. This is the standard configuration on OKX—all users share the same deposit address, and the Memo is used to identify which user you are.

Case B: You are using a multiplexed address (Muxed Address, starting with M)

The Stellar network supports muxed addresses; using an address starting with M can omit the Memo. However, whether OKX currently assigns such addresses by default depends on what the actual deposit page shows. If the page shows a Memo field, it means you need to fill it in.

Completion criteria: Confirm whether the Memo field is displayed on your OKX deposit page.

Step 2: Enter the Memo Correctly When Making the Transfer

When initiating an XLM transfer from an external wallet to OKX:

1. Receiving address: Enter the deposit address starting with G provided by OKX.
2. Memo field: Enter the Memo digit string provided by OKX.
3. Amount: Enter the quantity of XLM you want to deposit.

Completion criteria: The address and Memo are both correctly filled in, and the transfer is submitted successfully.

OKX's deposit tag is generally 7–8 digits; please refer to the actual display on the page. If the Memo is entered incorrectly, the deposit may not be credited properly, and you will need to contact customer support for manual processing.

Step 3: If You Forgot to Fill In the Memo

If you accidentally left out or entered the wrong Memo:

1. Do not submit again: First confirm that the transaction has been confirmed on-chain.
2. Prepare materials: Collect the transaction hash (TxID), the deposited currency, the amount, the correct Memo, and the incorrect Memo (if applicable).
3. Contact customer support: Submit a ticket through the OKX app or website's live chat, attaching the above materials.
4. Wait for processing: Engineers will follow up, but recovery is not 100% guaranteed.

Completion criteria: Customer support has accepted the ticket, entering the manual processing flow.

Common Reason for Failure

Mistaking the Memo as optional

The most common mistake is considering the Memo unimportant—leaving it empty or filling it with random digits. In fact, for deposits using a standard address (starting with G), the Memo is mandatory. Omitting the Memo will cause the deposit to fail to be credited automatically, resulting in significant delays. In some cases, it may not be recoverable at all.

Risk Reminder

• Both Memo and address are indispensable: The special aspect of XLM deposits is that the Memo is the unique identifier to distinguish users, not an optional field.
• Incorrect Memo requires customer support intervention: If the Memo is wrong, you need to submit a customer support ticket, and the processing time may be lengthy.
• Confirm wallet Memo support beforehand: Before initiating the transfer, confirm that your wallet supports filling in the Memo field; otherwise, you cannot complete the deposit.

How to Confirm Completion

After submitting the deposit, check the status in OKX's [Deposit History]. When the status changes to "Completed" and the asset balance updates, it means the Memo and address were correctly entered, and the deposit was successful. If the status shows "Pending" or the deposit has not arrived for a long time, check whether the Memo was filled in correctly.
