When it comes to depositing digital assets—especially USDT—on a cryptocurrency exchange like OKX, one of the most common yet critical questions users face is: which deposit network should I choose?
While the process may seem straightforward—enter the amount and confirm—the reality is more nuanced. Selecting the wrong network can result in lost funds or failed transactions. This guide breaks down everything you need to know about choosing the right deposit network on OKX, focusing on the three main USDT networks: ERC20, TRC20, and Omni, including their differences in speed, cost, and security.
Understanding USDT Deposit Networks
USDT (Tether) is a stablecoin pegged to the U.S. dollar, but it doesn’t run on just one blockchain. Instead, it exists across multiple networks, each with its own technical framework. The three most widely used are:
- Omni – Built on the Bitcoin blockchain
- ERC20 – Built on the Ethereum blockchain
- TRC20 – Built on the TRON (Tron) blockchain
These networks are not interoperable. This means USDT on the TRC20 network cannot be directly transferred to an ERC20 address, and vice versa. Sending funds to the wrong network may result in permanent loss.

Step-by-Step: How to Deposit USDT on OKX
Follow these steps to ensure a safe and successful deposit:
- Open the OKX app or website and log in to your account.
- Tap [Assets] > [Deposit].
- Search for USDT or select it from the list of available cryptocurrencies.
- Choose your preferred deposit network (e.g., TRC20, ERC20, or Omni).
- Copy the provided deposit address or scan the QR code.
- Go to your external wallet or exchange, initiate a withdrawal, and paste the OKX deposit address.
- Crucially, select the same network (e.g., TRC20) as the one chosen on OKX.
- Enter the amount and confirm the transaction.
⚠️ Important: Always double-check that the withdrawal network on the sending platform matches the deposit network selected on OKX. Mismatched networks are the leading cause of lost funds.
Key Differences Between ERC20, TRC20, and Omni
1. TRC20 (Tron Network) – Fast & Low-Cost
- Transaction Speed: ~1–3 minutes
- Average Fee: Less than $1 (often close to zero)
- Best For: Small to medium transfers where speed and low cost are priorities
TRC20 has become one of the most popular choices for USDT transfers due to its high throughput and minimal fees. With a TPS (transactions per second) capacity of up to 1500, Tron supports rapid settlements, making it ideal for traders and frequent users.

2. ERC20 (Ethereum Network) – Balanced Performance
- Transaction Speed: ~5–15 minutes (longer during congestion)
- Average Fee: $5–$20 depending on network load
- Best For: Users prioritizing wide compatibility and moderate security
ERC20 remains a trusted standard across most exchanges and wallets. While gas fees can spike during peak times, its broad adoption makes it a reliable fallback when other networks aren't supported.
3. Omni (Bitcoin Network) – Secure but Slow
- Transaction Speed: 10 minutes to several hours
- Average Fee: $10–$30+
- Best For: Large, infrequent transfers where security is paramount
Launched in 2014, Omni was the original blockchain for USDT. It leverages Bitcoin’s robust security, making attacks extremely costly. However, its slow speed and high fees have made it less practical for everyday use.
Frequently Asked Questions (FAQ)
Q: Can I send TRC20 USDT to an ERC20 address?
A: No. These networks are incompatible. Sending to the wrong address will likely result in permanent loss of funds.
Q: Which network should I use for small transfers?
A: Use TRC20—it offers near-instant confirmation and negligible fees, ideal for amounts under $1,000.
Q: Is ERC20 safer than TRC20?
A: Not necessarily. While Ethereum has a strong security model, Tron’s network is also well-established. The key is ensuring you use the correct network and verified address.
Q: Why does OKX show multiple deposit options for USDT?
A: Because USDT operates on multiple blockchains. You must match the sending network with your chosen deposit network.
Q: What happens if I send funds using the wrong network?
A: The transaction may fail or, worse, be lost permanently. Always confirm network compatibility before initiating a transfer.
Q: Are there any hidden costs with free transfers?
A: TRC20 transactions appear "free" because Tron burns minimal energy, but some wallets may require small bandwidth or energy stakes.
How to Choose the Right Network: A Quick Guide
| Use Case | Recommended Network |
|---|---|
| Fast, low-cost transfers | TRC20 |
| High-security large transfers | Omni |
| Broad compatibility | ERC20 |
| Frequent trading activity | TRC20 or ERC20 |
For most users, TRC20 offers the best balance of speed and affordability. However, if you're moving large sums and can afford higher fees for enhanced security, Omni or ERC20 may be preferable.
Final Tips for Safe Deposits
- ✅ Always verify both the address and network type before confirming any transaction.
- ✅ Start with a small test transfer when using a new wallet or exchange.
- ✅ Never share your private keys or recovery phrases.
- ✅ Enable two-factor authentication (2FA) on your OKX account.
Cryptocurrency transactions are irreversible—once sent, they cannot be canceled or refunded. Taking a few extra seconds to confirm details can prevent costly mistakes.
👉 Ensure your next deposit is fast, safe, and error-free with OKX’s trusted platform.
