How to Use DAppso’s TRX-Free Transfer Feature?

When making transfers on the TRON network, you need TRX to pay network fees. If you do not have enough TRX or you transfer often, you can use DAppso’s TRX-Free Transfer feature to pay fees directly with USDT.

To use this feature, visit DAppso and create a lite USDT account, which is a unique Gas Free contract account linked to your wallet address. After transferring USDT into this account, you can use the account balance to transfer USDT and pay fees.

This feature is powered by GasFree, a TRON ecosystem service provider, and uses TRON’s TIP-712 structured signature technology. In simple terms, you authorize transfers with an offline signature. GasFree then covers the required TRX resources and broadcasts the transaction, while you pay the service fee in USDT.

FAQ

Q1. How are transfer fees calculated?

The first transfer usually requires both an activation fee and a transfer fee. Subsequent transfers only require a transfer fee. The exact amount is subject to the fee displayed on the DApp page.

Current fee reference:

• First transfer: about 3 USDT, including a 1.5 USDT activation fee and a 1.5 USDT transfer fee.
• Subsequent transfers: about 1.5 USDT per transaction.

Note: These fees are set and collected by the GasFree service provider to cover the cost of paying TRX resources, broadcasting transactions, and providing the service.

Q2. Why is TRX required when depositing USDT?

Because transferring USDT from your wallet address to the corresponding lite account is a regular on-chain transfer, a small amount of TRX is required to pay the network fee.

After the tokens are deposited into the lite account, you can use USDT to pay fees for future transfers from that account, without preparing additional TRX.

Q3. Is the lite account a custodial account?

No. The lite account is generated for your wallet address, and you have full control over it. Tokens in the account can only be transferred after you sign with your wallet’s private key.

The third-party service provider only pays the TRX fee and broadcasts the transaction. It cannot access or control your assets.

💡 Make sure to back up your wallet mnemonic or private key properly. Store it securely offline. Never take screenshots, photos, or share it with anyone.

Q4. How do I contact DAppso?

On the lite account DApp page, tap Feedback to access its official Telegram support.
