We are happy to share great news for everyone who holds TRX and USDT: on October 19, 2026, in version 2.114.74 for iOS and Android, Gem Wallet integrated SunSwap - our new partner on the TRON network. Now our users swap TRX and USDT right on the blockchain, and SunSwap covers almost all the energy for every swap.
Gem Wallet Opens TRX and USDT Swaps Through SunSwap
With SunSwap, our users swap TRX and USDT on the TRON network through the pools of the network’s main DEX: Gem Wallet finds the best rate, and the trade goes through right on the blockchain, with no extra steps.
The partnership with SunSwap is one more step toward Gem Wallet’s goal: giving users on every network swaps straight through a DEX.
Say you got paid in USDT, and you have almost no TRX left for fees. A couple of taps in Gem Wallet - and part of your USDT has already turned into TRX, so your transfers go through without a worry again.
SunSwap - the Main DEX on TRON
SunSwap is a DEX on the TRON network with automated liquidity: token pools set the rate, and the swap happens right on the blockchain. In the 30 days before October 29, 2026, about $1.5 billion in swaps went through SunSwap - more than 85% of all DEX volume on TRON. All versions of SunSwap pools hold almost $600 million, and $151 million of it sits in SunSwap v3, the pool version with four fee tiers that Gem Wallet works with (according to DefiLlama, Gem Wallet calculation).
SunSwap is part of SUN.io - the DeFi platform of the TRON network that brings swaps, staking, liquidity rewards, and protocol governance votes together in one place. SUN.io bets on the people who provide liquidity: SunSwap pool fees go entirely to liquidity providers, and the platform takes no cut of its own.
How Gem Wallet Finds the Best Rate in SunSwap Pools
Gem Wallet works out the SunSwap rate right on the blockchain: every quote is a request to the SunSwap v3 quoter on a TRON node. A swap goes through three steps:
- Finding Pools: The wallet finds SunSwap v3 pools for your pair across all four pool fee tiers - 0.01%, 0.05%, 0.3%, and 1% - and this fee goes to liquidity providers.
- Comparing Routes: Gem Wallet requests quotes for every route at the same time - through one pool or through two, with WTRX or USDT in the middle - and picks the one that gives more tokens. Routes that lose by more than 3% are no longer checked on the next quotes.
- Trade in the SunSwap Router: The chosen route goes to the router - the SunSwap smart contract that runs the swap through the right pools - and you sign the swap yourself, on your own device.
WTRX is TRX in the form of a TRC20 token that SunSwap pools work with. Permit2 is the SunSwap approval contract: you give the router access to your USDT once, and after that you confirm each swap with a signature.
The table below shows how much USDT SunSwap gave for TRX worth $100 to $10,000, based on Gem Wallet quotes from October 26, 2026:
| TRX Swap Amount | SunSwap Gave | Share of the Amount Received in USDT |
|---|---|---|
| $100 | 99.27 USDT | 99.27% |
| $1,000 | 992.73 USDT | 99.27% |
| $10,000 | 9,927.20 USDT | 99.27% |
The share of the amount that arrives in USDT barely depends on the size of the swap (Gem Wallet calculation).
How to Swap TRX for USDT via SunSwap in Gem Wallet
- Find TRX among your assets in Gem Wallet and tap Swap
- Choose USDT on TRON as the token you receive
- Enter how much TRX you want to give
- Check the provider in the swap details: when SunSwap has the best rate, SunSwap appears next to Provider, with the rate and the minimum amount you receive below it
Important: The TRON network fee for a swap is paid in the native token, so keep a small amount of TRX on your balance.
Benefits of the SunSwap Integration for Gem Wallet Users
Gem Wallet is a mobile self-custody wallet for iOS and Android with 100% open-source code, where you can securely store, swap, and stake crypto, and buy it with a credit card right in the app. Here is what the SunSwap integration gives our users when swapping TRX and USDT:
- Energy Covered by SunSwap: SunSwap pays 99% of the energy for every swap through its router, so you spend just 0.2-0.6 TRX on energy instead of tens of TRX (transactions on the TRON network, October 18, 2026).
- Best Rate From $100 to $10,000: Based on quotes from October 26, 2026, SunSwap gave more than any other Gem Wallet provider for TRX worth $100, $1,000, and $10,000.
- No Extra Transactions: A swap - even through two pools - goes through as one transaction, and the Permit2 approval for USDT is needed only on your first swap.
- Built-In DEX Aggregator: On every swap, Gem Wallet compares provider rates and offers the best one right away, and you can pick SunSwap manually if you like.
- Simple and Clear Interface: Swaps in the app are clear and accessible from the very first second - choose the tokens, enter the amount, confirm. Beginners and experienced crypto enthusiasts alike will find their way around.
Energy is the TRON network resource that pays for smart contract calls: if an account has no energy, the network burns TRX for it.

Conclusion
With SunSwap, swaps on TRON cost a fraction of a TRX in energy and run at the best rate from the pools of the network’s main DEX - thanks to our partner for making it possible. Update Gem Wallet and swap your TRX for USDT through SunSwap right on the blockchain - securely and privately.
