Cryptocurrency deposits require precision—entering the correct deposit address and, when necessary, the proper tag (also known as memo) is crucial to ensure your funds arrive safely. Mistakes in either field can result in irreversible losses. This guide walks you through the entire process of verifying and using deposit addresses and tags across both mobile and web platforms, with clear instructions tailored for different digital assets.
Whether you're depositing stablecoins like USDT or cryptocurrencies such as XRP that require additional identifiers, understanding these steps will help protect your assets and streamline your transactions.
Important Notice: Updated Deposit Addresses (March 2025)
Due to a recent system upgrade, some cryptocurrency deposit addresses were updated on March 27, 2025. Please take note of the following:
- Your previous deposit addresses remain functional in the short term, and funds sent to them will not be lost.
- However, you are strongly advised to update your whitelisted addresses on external wallets or exchanges within the next 3 months.
- Migrating to the new addresses ensures long-term compatibility, improved security, and smoother deposit processing moving forward.

What You Need to Know Before Depositing Crypto
Before initiating any deposit, it's essential to understand two key elements: deposit addresses and tags/memos.
1. Deposit Address
Every cryptocurrency has a unique receiving address generated by your exchange or wallet. This string of characters acts like a bank account number—sending funds to the correct one is mandatory.
2. Tag / Memo (Required for Certain Coins)
Some digital assets, including XRP, XLM (Stellar), and EOS, require an additional identifier called a tag or memo. This is typically a numeric or alphanumeric code that directs your funds to the correct sub-account within the receiving platform.
❗ Failing to include the correct tag when required may result in lost or delayed deposits—even if the address is accurate.
Always double-check whether your chosen coin needs a tag before sending funds.
3. Match the Network Exactly
One of the most common causes of failed deposits is network mismatch.
Ensure that:
- The deposit network selected on your receiving platform (e.g., OKT Chain, TRON, Ethereum)
- Matches exactly with the withdrawal network used on the sending wallet or exchange
Using different networks—even for the same token type (e.g., USDT on TRON vs. USDT on Ethereum)—can lead to permanent loss of funds.
How to Deposit via Mobile App
The mobile app offers a streamlined experience for quickly accessing deposit details. Below are two common scenarios based on whether a tag is required.
Scenario 1: Coins Requiring Only an Address (e.g., USDT)
For tokens like USDT on networks such as OKT Chain, TRON, or Ethereum, only the deposit address is needed.
Steps:
- Open the OKX app and tap [Assets] > [Deposit] > [Deposit Crypto]
- Search for the cryptocurrency (e.g., USDT)
- Select the preferred network (e.g., OKT Chain)
- Tap [Copy Address] and paste it into your sending wallet
✅ No tag required — just confirm the network matches before proceeding.
Scenario 2: Coins Requiring Both Address and Tag (e.g., XRP)
Assets like XRP require both a deposit address and a unique tag.
Steps:
- Choose the coin (e.g., XRP) and its corresponding network (e.g., Ripple)
- The app will display a notice indicating that a tag is required
Swipe to confirm, then view and copy both:
- Deposit Address
- Tag (Memo)
- When withdrawing from another platform, enter both fields accurately
⚠️ Never omit the tag when sending XRP. Even small errors in digits can cause transaction failure or loss of funds.

How to Deposit via Web Platform
Using the OKX website provides a clear interface for managing deposits with full visibility over network options and requirements.
Steps:
- Log in to your OKX account at okx.com
- Navigate to [Wallet] > [Assets] > [Deposit]
- Select or search for the cryptocurrency you wish to deposit
- Choose the appropriate deposit network (e.g., ERC-20, BEP-20, Ripple)
If the selected coin requires a tag (like XRP), a pop-up will appear stating:
“This currency requires a tag (memo). Please make sure to include it when withdrawing.”
Click [I Understand] to reveal both:
- The deposit address
- The associated tag/memo
Carefully copy both pieces of information and use them during the withdrawal process from your external wallet or exchange.
Frequently Asked Questions (FAQ)
Q: What happens if I forget to include the tag when depositing XRP?
A: If you send XRP without the correct tag, the transaction may not be credited to your account. While some platforms can manually recover such funds, others cannot—potentially resulting in permanent loss. Always verify tag requirements before sending.
Q: Can I reuse my deposit address for multiple transactions?
A: Yes, most deposit addresses can be reused safely for the same cryptocurrency and network. However, consider updating to new addresses after major system upgrades (e.g., post-March 2025) for security and compatibility.
Q: Is there a difference between "Tag" and "Memo"?
A: No—they refer to the same thing. Different platforms use different terms: "Tag" is common for Ripple (XRP), while "Memo" is often used for Stellar (XLM). Both serve as secondary identifiers.
Q: Why do some coins need a tag but others don’t?
A: Coins built on shared ledger systems (like Ripple or Stellar) use tags/memos because multiple users share the same base address. The tag ensures funds go to the right user account within that shared structure.
Q: How do I know if my selected network supports tags?
A: The deposit interface will explicitly notify you if a tag is required once you select the coin and network. Never assume—always check directly in the app or web portal.
Final Tips for Safe Deposits
- Always double-check both address and tag before confirming any transaction.
- Use official apps or verified websites only—avoid phishing links.
- Start with a small test transaction when depositing large amounts.
- Keep records of recent transactions for reference.
- Regularly update whitelisted addresses on third-party platforms after system changes.
Security starts with attention to detail. By following these best practices, you minimize risks and maintain full control over your digital assets.
