How to Deposit USDT on OKX? Which Network Is Better: TRC20 vs ERC20
We state the core conclusion first: For regular small-value transfers, TRC20 is the top choice, as it is extremely fast and low-cost; only choose ERC20 for large transfers or use cases that involve DeFi interactions. The most critical non-negotiable rule is — always select the exact same network that the receiving platform supports. The two networks are completely incompatible, and you will lose your funds permanently if you pick the wrong one.
1. Navigate to the OKX Deposit Page
After finishing account registration and identity verification, tap [Assets] - [Deposit] - [Deposit Crypto] on the OKX App homepage, then select USDT from the supported cryptocurrency list.
Completion Checkpoint: You will be redirected to the network selection page, where you can view the full list of USDT deposit networks supported by OKX.
2. Compare Core Differences Between TRC20 and ERC20
OKX currently supports USDT deposits across multiple blockchains including Tron (TRC20) and Ethereum (ERC20). The key distinctions between the two are listed below:
| Comparison Dimension | TRC20 (Tron Network) | ERC20 (Ethereum Network) |
|---|---|---|
| Address Format | Starts with the letter T, 34 characters total | Starts with 0x, 42 characters total |
| Transfer Fee | Extremely low, usually less than $1 | Relatively high, usually $3-15, can spike much higher during network congestion |
| Arrival Speed | Very fast, usually confirmed within seconds | Slower, heavily affected by Ethereum network congestion |
| Applicable Scenarios | Daily transfers, small deposits, high-frequency trading | DeFi lending/yield farming, institutional-grade transactions, large-value transfers |
Completion Checkpoint: You have confirmed which network to use based on your actual needs. If you are not participating in DeFi projects built on Ethereum, TRC20 is fully sufficient for all regular use cases.
3. The Most Critical Step: Verify the Network of Your Sending Source
Before selecting a network on OKX, first confirm which platform or wallet you are sending USDT from, and what networks that sending platform/wallet supports.
Scenario A: Withdrawing from another exchange to OKX Go to the withdrawal page of your sending exchange, and check the supported USDT network options there. If it only supports ERC20, you must also select ERC20 on the OKX side. The two networks must be 100% identical, otherwise your assets will be lost permanently.
Scenario B: Transferring from your self-custody wallet to OKX
Open your wallet (such as MetaMask, TokenPocket) and check the blockchain network corresponding to the address you are using. ERC20 addresses start with 0x, while TRC20 addresses start with T. The network you select on OKX must match the network that your wallet address is native to.
Common Cause of Failed Deposits: You copied a TRC20 deposit address from OKX, but selected the ERC20 network on your sending platform to initiate the transfer. When the two networks do not match, your assets cannot be recovered.
4. Complete the Deposit
After confirming the correct network, click the corresponding network option on the OKX deposit page to generate and copy your unique deposit address. Go back to your sending exchange or wallet, paste this address into the recipient address field on the withdrawal/transfer page, and double confirm that the selected network on your sending platform is exactly the same as the one you chose on OKX, enter the transfer amount and submit.
The arrival time depends on the blockchain network's confirmation speed. TRC20 transactions usually process very quickly, while ERC20 transactions may be delayed due to Ethereum network congestion. You can check the real-time progress in the deposit history section of your OKX account.
Risk Reminder: Some cryptocurrencies (such as XRP, EOS) require you to fill in a dedicated Tag/Memo field when depositing, but this is not required for USDT deposits — you only need to enter the address. Do not omit the Tag/Memo when depositing other supported coins, otherwise your funds will not arrive successfully.
FAQ
Q: Is TRC20 completely free of charge? The on-chain transaction fee for the TRC20 network is extremely low (nearly zero in most cases), but your sending platform (such as OKX) may charge a fixed withdrawal service fee (for example, 1 USDT). The exact fee will be displayed on the platform page when you perform the operation.
Q: Can I recover my funds if I selected the wrong network for deposit? It is extremely difficult. If the networks do not match, your assets are almost always lost permanently. The only rare exception is if the deposit address you sent to belongs to the same centralized platform (for example, you sent ERC20 USDT to the TRC20 version of the same address generated by that platform). Some centralized exchanges may try to help you recover the funds via customer support, but this usually charges extra fees, takes weeks to process, and there is no guarantee of success.
Q: Does USDT on TRC20 have the same value as USDT on ERC20? Yes, they are identical in value. Both versions of USDT are issued by Tether, pegged 1:1 to the US dollar. The only difference between them is the underlying blockchain network and transfer mechanism.
Next Steps
After the deposit is submitted, go to the [Assets] page on OKX to confirm if your USDT balance has been updated. If the funds do not arrive for a long time, check if the transaction on your sending platform has been fully confirmed on the blockchain, and view the deposit progress in your OKX deposit history. For your first deposit, we recommend testing the full process with a small amount (for example, 10 USDT) first, and only transfer larger amounts after you confirm the test was successful. If you have not completed your OKX account registration yet, remember to enter the invite code 24U2795 in the dedicated field during registration (it cannot be added retroactively after sign-up).
