# Gem Wallet Expands STON.fi Swaps on TON: Hamster Kombat and More Jettons From v2 Pools
> Gem Wallet expands STON.fi swaps on TON - learn how to swap Hamster Kombat (HMSTR) and other jettons for Gram right in your wallet in just a few taps.

Starting September 29, 2026, with version 2.114.54, Gem Wallet has connected STON.fi v2 pools on TON - on iOS and Android. Now you can swap Hamster Kombat (HMSTR) and other jettons from these pools right in your wallet - no pool hunting and no third-party apps.

## Gem Wallet Expands STON.fi Swaps on TON

<a href="https://ston.fi/" rel="nofollow">STON.fi</a> is a DEX with liquidity pools on <a href="https://ton.org/" rel="nofollow">TON</a> (The Open Network): over its lifetime, it has processed 37 million swaps worth $8 billion for 6 million users (according to ston.fi, October 2026). Before, Gem Wallet looked for STON.fi pools on two routers (the smart contracts that swaps go through), and now it also checks the v2.1 and v2.2 routers. As a result, [jettons](https://gemwallet.com/jetton-wallet/) (tokens on the TON network) with pools on these routers are now available for swaps - for example, HMSTR, the token of the Hamster Kombat game.

You hold HMSTR and want to get [Gram](https://gemwallet.com/gram-wallet/) (prev. Toncoin) - Gem Wallet finds the STON.fi v2 pool and shows the rate before you confirm. We keep expanding swaps for our users: Gem Wallet picks the route itself and shows the best rate, and if you like, you can choose a provider from the list.

## How to Swap HMSTR via STON.fi DEX Provider

1. Open Gem Wallet, select HMSTR, and tap Swap
2. In the You Receive field, choose Gram
3. Enter the HMSTR amount
4. Open the swap details - the Provider row shows STON.fi v2, the rate, and the minimum amount you receive

***Important:** The TON network fee for the swap is charged in Gram, so keep a small amount of Gram on your balance.*
