When navigating the world of digital assets, one common question arises: Does a cryptocurrency deposit address change on the same exchange for the same coin? For most users, depositing funds into an exchange is a routine activity—whether topping up for trading, staking, or investing. Understanding how deposit addresses work is crucial to ensuring secure and successful transactions.
In general, your deposit address for a specific cryptocurrency on a given exchange remains the same over time. This means once you generate a USDT (TRC20) address on OKX, for example, you can reuse it for multiple deposits. However, there are important exceptions and best practices to be aware of.
Let’s dive into the details, explore when and why addresses might change, and provide a clear guide to help you avoid costly mistakes.
How Cryptocurrency Deposit Addresses Work
Each cryptocurrency wallet or exchange account generates a unique public address for receiving funds. This address is derived from your private key and functions like a bank account number—safe to share for receiving payments but never to be used for sending without proper authorization.
On centralized exchanges like OKX, when you request a deposit address for Bitcoin (BTC), Ethereum (ETH), or stablecoins like USDT, the platform assigns you a valid receiving address tied to your account. In most cases:
✅ The address stays constant
✅ It supports repeated deposits
✅ It remains active until the exchange enforces a change

This consistency simplifies the process—users don’t need to generate a new address every time they want to deposit. However, this doesn't mean the address never changes.
When Might Your Deposit Address Change?
While rare, there are legitimate scenarios where your previously used deposit address may become invalid or replaced. Here are the top three reasons:
1. Exchange Policy Updates
Exchanges periodically update their internal systems for compliance, security, or technical improvements. These updates may include rotating user addresses or migrating to new wallet infrastructures. If such a policy shift occurs, the exchange will typically notify users through email or in-app alerts.
2. Security or Maintenance Events
If an exchange detects unusual activity or potential compromise within its wallet system, it may proactively rotate deposit addresses across all users as a protective measure. This helps isolate funds and prevent unauthorized access—even if no individual account has been breached.
3. Blockchain Network Upgrades or Forks
When a cryptocurrency undergoes a major protocol upgrade or hard fork (e.g., Ethereum's transition to Proof-of-Stake or Bitcoin Cash splitting from Bitcoin), exchanges may need to update their wallet infrastructure. As a result, older deposit addresses could be deprecated in favor of new formats compatible with the upgraded chain.
🔔 Always monitor official exchange announcements. Never assume your old address is still valid after long periods of inactivity.
Best Practices for Using Deposit Addresses
To protect your assets and ensure smooth transactions, follow these expert-backed tips:
- Verify Before Sending: Always double-check the full address and network before initiating any transfer.
- Start Small: For first-time deposits to a new wallet or after long breaks, send a small test amount first.
- Match Networks Exactly: Ensure the withdrawal network (e.g., ERC20, TRC20, BEP20) matches the deposit network on the receiving exchange.
- Avoid Reusing Withdrawal Addresses: While deposit addresses can be reused, never assume withdrawal addresses are static—some platforms generate one-time use addresses for withdrawals.
- Bookmark Official Pages: Use only official exchange websites to generate deposit addresses—never trust links from emails or social media.
Step-by-Step Guide: How to Deposit Crypto on a Major Exchange
Depositing crypto is straightforward if you follow the correct procedure. Below is a universal guide applicable across leading platforms like OKX:
Step 1: Log In and Navigate to Deposit
After logging into your account, go to the Assets or Wallet section. Look for “Deposit” or “Fund Account.”
Step 2: Select Your Cryptocurrency
Choose the coin you wish to deposit—such as BTC, ETH, or USDT. Be precise; depositing the wrong token (e.g., sending ETH on a BEP20 network incorrectly) can result in permanent loss.
Step 3: Choose the Correct Network
This step is critical. For USDT, you’ll see options like:
- TRC20 (Tron network – low fees)
- ERC20 (Ethereum network – higher fees)
- BEP20 (Binance Smart Chain)
⚠️ Mismatched networks = lost funds. Always confirm the sending platform supports the same network.
Step 4: Copy and Confirm the Address
Click “Copy” to transfer the deposit address to your clipboard. Paste it carefully into the recipient field of your sending wallet. Some exchanges also provide QR codes for mobile use.
Step 5: Initiate Transfer and Wait
Send the funds and wait for blockchain confirmation. Processing times vary by network congestion and transaction fees.
Frequently Asked Questions (FAQ)
Q: Can I reuse my deposit address multiple times?
Yes. Most exchanges allow repeated use of the same deposit address for a specific cryptocurrency unless otherwise notified.
Q: What happens if I send crypto to an old or inactive address?
If the address has been deactivated due to system upgrades or security changes, your funds may not be credited—or worse, could be lost permanently. Always verify current addresses before sending.
Q: Why do some platforms generate new addresses each time?
Some wallets use hierarchical deterministic (HD) systems that create unique addresses per transaction for privacy. Exchanges usually avoid this for simplicity but may adopt it in future updates.
Q: Should I worry about hackers knowing my deposit address?
No. Public addresses are designed to be shared safely. The risk lies in exposing your private key or recovery phrase—not the public address itself.
Q: How do I know if my deposit address has changed?
Check directly in your exchange account under the deposit section. If the displayed address differs from your saved one, use the new one. Also watch for official notifications via email or app alerts.

Final Thoughts: Security Starts With Awareness
Understanding whether your cryptocurrency deposit address changes is more than just technical knowledge—it's a core part of securing your digital wealth. While most exchanges maintain consistent addresses for convenience, staying informed about policy shifts, network upgrades, and security events is essential.
Always generate deposit addresses from the official exchange interface, match networks precisely, and never rush large transfers without verification.
By adopting cautious habits and leveraging secure platforms with robust infrastructure, you minimize risks and maximize control over your financial future in the decentralized world.
Remember: Your crypto safety depends not just on technology—but on your actions.
