Important reminder

USDT exists on multiple blockchain networks that are not interchangeable.
Before sending USDT, always confirm that the sending and receiving networks match.

If the networks are different, you must swap your USDT to the correct network before sending. Sending USDT to the wrong network may result in permanent loss of funds.

Understanding USDT network types

USDT is issued on several blockchain networks, including:

• ERC20 – Ethereum network
• TRC20 – TRON network
• TON – TON network

Each network operates independently, meaning USDT on one network cannot be directly sent to an address on another network without conversion.

How to swap USDT across networks in Zengo

Zengo allows you to convert USDT between supported networks using the Swap feature.

Example: Swapping USDT from ERC20 to TRC20

  1. Open your USDT wallet in Zengo

  2. Tap Swap

  3. Select USDT ERC20 as the asset you are swapping from

  4. Select USDT TRC20 as the asset you want to receive

  5. Confirm the swap

Once completed, your USDT will be on the TRON network and can be sent to a TRC20 address.

Example: Swapping USDT from TON to TRC20

TON and TRON are separate networks, so a swap is required.

  1. Open your TON USDT wallet

  2. Use the Swap feature to convert TON USDT to TRC20 USDT

  3. After the swap completes, send your USDT to the TRC20 address

Network fees and requirements

Each network has its own fee model.
​

TRC20 (TRON)

TRON transactions require TRX to cover bandwidth and energy fees.
If your wallet does not have enough resources, a small TRX fee will be used.

TRC20 is usually the cheapest network for USDT transfers.

ERC20 (Ethereum)

Ethereum transactions require ETH for gas fees.
Gas fees can vary depending on network congestion and are typically higher than TRON.

TON

TON transactions require TON coins to pay network fees.
Fees are generally low but depend on TON network activity.

Common mistakes to avoid

• Sending USDT to an address on a different network without swapping first
• Not holding the required network token (TRX, ETH, or TON) for fees
• Confusing address formats between networks
• Assuming all USDT addresses are interchangeable

If you are unsure

Before sending USDT, always confirm with the receiving platform which network is required.
If you are unsure, contact support before completing the transaction.

Key takeaway

USDT is the same asset across networks but lives on different blockchains.
To move USDT safely, always match the network or swap before sending.
