Sending crypto assets can sometimes be challenging for beginners. One of the most common mistakes is selecting the wrong blockchain network. Always verify the correct transfer blockchain before initiating a transaction.
Cryptocurrencies can only move across blockchains that are compatible with their native design. Each blockchain uses a unique cryptographic code—essentially, blockchains "speak different languages." While OKX automatically selects the appropriate transfer network for most cryptocurrencies, users may occasionally need to manually choose a blockchain from the provided list.
Caution: Choosing the wrong blockchain can result in irreversible loss of funds. Below, we illustrate how to select the right blockchain using USDT as an example.
Key Rule: Deposit and Withdrawal Networks Must Match
The withdrawal network on OKX must correspond to the deposit network. For instance:
- If you deposit USDT via ERC20, withdraw via ERC20.
- If you deposit via TRC20, withdraw via TRC20.
Mismatched networks will lead to failed transactions or lost assets.
Step-by-Step Guide to Selecting a Deposit Network
Navigate to Assets:
- Open the OKX app/web platform.
- Click Assets > Overview > Deposit > On-Chain Deposit > USDT.
Choose Your Network:
- Options include USDT-ERC20, USDT-TRC20, and others.
- All networks function, but differ in speed, fees, and security.
- Network Comparison:
| Network | Speed | Fees | Best For |
|------------|--------|--------|-------------------|
| TRC20 | Fast | Low | Small transfers |
| ERC20 | Slow | High | Large transfers | Complete the Deposit:
- Copy the OKX deposit address.
- Paste it into the Withdrawal section of your external wallet/exchange.
