When depositing USDT on exchanges like OKX, many users face a common question: which network should I choose? While it might seem straightforward, selecting the correct blockchain network—ERC20, TRC20, or Omni—is crucial for a successful and cost-effective transfer. Each network operates on a different blockchain and offers distinct advantages in terms of speed, fees, and security. This guide will help you understand the differences and make an informed choice when using OKX.
How to Select a Deposit Network on OKX
Follow these steps to ensure a smooth deposit process on the OKX platform:
- Open the OKX mobile app and tap the "Deposit" button.
- Select the cryptocurrency you wish to deposit. If it’s not listed among the popular assets, use the search bar to find it.
- For USDT deposits, choose your preferred network (e.g., ERC20 or TRC20). You can then either save the QR code or copy the deposit address provided.
- Navigate to the withdrawal page on the platform where you hold your funds. Select USDT as the withdrawal currency and paste the OKX deposit address (or scan the QR code). It is critical to select the same network for withdrawal as you did for deposit. For example, if you chose USDT-TRC20 on OKX, you must also select TRC20 on the sending platform.
- Enter the amount and confirm the withdrawal.
Important considerations:
- Blockchain confirmations may cause delays; allow time for the transaction to process.
- Always match the network type between the sending and receiving platforms. Sending USDT via TRC20 to an ERC20 address, for instance, will result in permanent loss of funds.
- Double-check the address and currency type. Do not send Litecoin (LTC) to a Bitcoin Cash (BCH) address, for example.
- Some currencies require a Memo or Tag. Ensure this information is accurately provided to avoid failed transactions.
Key Differences Between Deposit Networks
The primary differences between ERC20, TRC20, and Omni networks lie in transaction speed, fees, and security:
- TRC20 (Tron Blockchain): Ideal for users prioritizing speed and low cost. Transactions are typically fast, often completing within minutes, and carry no network fees. However, it may be less secure compared to other options.
- ERC20 (Ethereum Blockchain): Offers a balance between security and speed. Transaction fees are moderate (around 2 USDT), and transfers are generally faster than Omni but slower than TRC20. It is widely supported and trusted for regular trading.
- Omni (Bitcoin Blockchain): Provides the highest level of security but is slower and more expensive. Transactions can take longer to confirm, and fees are significantly higher (approximately 5 USDT). This network is often used for large, non-urgent transfers.
Comparing USDT Networks: ERC20, TRC20, and Omni
Omni-USDT
Launched in 2014, Omni-USDT is the original version of Tether and operates on the Bitcoin blockchain. It is considered highly secure due to the robustness of Bitcoin’s network, making it suitable for large transactions. However, its slow transaction speed and high fees have made it less popular for everyday use.
ERC20-USDT
Introduced in 2018, ERC20-USDT runs on the Ethereum blockchain. It strikes a balance between security and efficiency, with faster processing times than Omni and moderate fees. It is widely adopted by exchanges and traders for its reliability.
TRC20-USDT
This version operates on the Tron network and is known for instant, fee-free transactions. While convenient for small, frequent transfers, it may pose higher risks due to the relatively lower security of the Tron blockchain.
It is essential to remember that these USDT versions are not interchangeable. Sending Omni-USDT to an ERC20 or TRC20 address will result in loss of funds. Always verify the network type before initiating a transfer.

Frequently Asked Questions
What happens if I send USDT using the wrong network?
If you send USDT to an address on a different network (e.g., ERC20 to a TRC20 address), the transaction will not be processed, and your funds may be permanently lost. Always ensure the network matches on both ends.
Which network is best for frequent, small trades?
TRC20 is ideal for frequent, small transactions due to its zero fees and fast processing times. However, for larger amounts, consider ERC20 or Omni for enhanced security.
Are there any fees for depositing USDT on OKX?
OKX does not charge deposit fees, but network fees may apply depending on the blockchain. TRC20 has no network fees, ERC20 charges around 2 USDT, and Omni costs about 5 USDT per transaction.
How long does a USDT deposit usually take?
Transaction times vary by network. TRC20 deposits are often completed within minutes, ERC20 may take slightly longer, and Omni can require more time due to blockchain confirmations.
Can I convert between different USDT networks on OKX?
Yes, OKX allows users to convert between supported USDT networks within the platform. This feature enables flexibility without needing external transfers.
Is TRC20 USDT safe to use?
While TRC20 is generally safe for everyday use, it is less secure than ERC20 or Omni. For significant amounts, using a more secure network is advisable.
Always prioritize safety and verify all transaction details before confirming transfers. Understanding these network differences will help you optimize your crypto experience.
