About STON.fi

STON.fi is a decentralized exchange (DEX) protocol on the TON blockchain (The Open Network). It uses an AMM (Automated Market Maker) model, allowing you to swap tokens without a centralized platform. You can also earn a share of trading fees by providing liquidity. Powered by TON, STON.fi features low transaction fees and fast confirmations.

Swap Tokens on STON.fi

Before you start

Ensure your TON wallet holds sufficient GRAM (prev. TON) to cover network fees.

Steps

  1. Open your TON wallet in imToken, go to the Browser tab, then search for STON.fi or visit: https://ston.fi/ 
  2. In the DApp, authorize access to your wallet address and confirm the Terms of Use.
  3. Tap Connect (top right) → Select Ton Connect to connect your wallet.
  4. Select the token you want to pay and the token you want to receive, enter the amount, then tap Swap → Confirm swap. Sign and Send the transaction to complete the swap.
  5. After the transaction is confirmed, return to your wallet home page to check the received tokens.

Provide Liquidity on STON.fi

A liquidity pool is a “fund pool” formed by users depositing a pair of tokens, which enables other users to swap. After you provide liquidity, you will share the pool’s trading fees based on your share.

Note: Providing liquidity may involve impermanent loss (price changes can alter the asset composition you receive when withdrawing). Please make sure you understand the mechanism before participating.

Steps

  1. On the STON.fi page, go to Pools to check details such as APR and TVL for each pair.
  2. Choose the pool you want to join (e.g., USDe/USDT). In addition to fee revenue, you may also receive Ethena points (subject to the rules shown on the campaign page).
  3. Tap Add liquidity, enter the amount for one token, and the DApp will automatically calculate the required amount of the other token based on the current pool ratio.

Tip: If you want to customize the deposit ratio, enable Arbitrary provision in supported pools.

  1. Tap Preview liquidity provision → Confirm liquidity provision, then sign and Send the transaction in your wallet.

Once completed, you will receive LP tokens (e.g., USDe-USDT LP).

What are LP tokens?

LP tokens (Liquidity Provider Tokens) act as receipts issued by the protocol after you deposit two tokens into a specific STON.fi pool. They represent your share of the pool. When you withdraw liquidity, the protocol will burn the corresponding LP tokens and return the two tokens to you according to your share (including any accumulated fee revenue).

Check and Withdraw Liquidity

  1. From the DApp home page, go to Spotlight → Ethena on TON campaign page to check Ethena points. Points are typically distributed within 24 hours after providing liquidity (subject to the page instructions).
  2. On the campaign page, you can view your USDe/USDT participation. Or go to Pools→ My pools to see the pools you joined.
  3. Enter the pool and tap Withdraw, choose the withdrawal percentage, then tap Withdraw Liquidity and sign Send in your wallet.
  4. After confirmation, return to your wallet home page to check the received tokens.

FAQ

Q1: Where can I view my LP tokens?

  • In the STON.fi DApp: Go to Pools → My pools to see the pools you joined and your LP positions.
  • In a block explorer: imToken’s TON wallet currently does not display DeFi assets (such as LP tokens). You can enter your wallet address in the TON explorer Tonviewer to view your token holdings.

Q2: Why are the two token amounts different after I withdraw liquidity?

This is mainly due to:

  • Fee revenue: Trading fees accumulate in the pool. When you withdraw, you receive your share of this revenue.
  • Impermanent loss: Price changes can rebalance the pool’s asset ratio, which adjusts the amounts of the two tokens in your share.
