Its main strengths are a focused single-chain design, about $21.9 million in TVL and a full set of tools including pools, staking and a DAO.

What is STON.fi?
STON.fi is a decentralized exchange on the TON blockchain. DefiLlama describes it as a decentralized automated market maker and lists it under DEXs, with TVL of about $21.9 million and a listing date of December 2022.
The homepage focuses on token swaps and offers pools, staking, a Spotlight section and a DAO. A developer area links to documentation and GitHub, and a support area covers how to add new tokens and report abuse. The site carries a disclaimer that nothing on it is investment advice.
The project has a native token, STON, and a Twitter account under the handle ston_fi. DefiLlama lists no audits, which is the main gap in the public data supplied here.
How STON.fi works
STON.fi is an automated market maker. Instead of matching buyers and sellers in an order book, it uses pools of two tokens funded by liquidity providers. A pricing formula sets the exchange rate based on the ratio of tokens in the pool.
When you swap, you add one token to a pool and take the other out, and the rate shifts slightly with trade size. Liquidity providers deposit pairs of tokens and usually earn a share of the trading fees in return.
The homepage also lists staking, a Spotlight section and a DAO with governance rules. The project does not explain these in detail, so readers should check the documentation for how they work.

Pros and cons
What we like
- Focused on TON, so it covers one ecosystem with a dedicated swap interface.
- About $21.9 million in TVL suggests meaningful liquidity for a single-chain DEX.
- Offers swaps, pools, staking and DAO governance in one place.
- Has been listed since December 2022, so it has some track record.
- Developer documentation and GitHub are linked from the site.
- Includes a process for adding tokens and reporting abuse.
Watch out for
- No audits are listed on DefiLlama, so readers must check the documentation for any security reviews.
- Liquidity is concentrated on a single chain, so the DEX depends on the health of the TON ecosystem.
- Fee levels are not stated and need to be checked in the app.
- TVL fell 3.9% over seven days, a reminder that pool depth can change.
- As with any AMM, liquidity providers face impermanent loss and smart-contract risk.
- Thinly traded tokens can have high slippage and some listed tokens may be low quality.
STON.fi fees
Public sources do not publish fee figures for STON.fi. Swap fees, pool fees and any protocol share should be shown in the app when you preview a trade, and in the documentation.
On top of protocol fees, TON network fees apply to every transaction, and slippage can raise the real cost on thin pools. Check the quoted price impact before you confirm a swap.
Is STON.fi safe?
DefiLlama lists zero audits for STON.fi. That does not prove the code is unsafe, but readers should look in the documentation and GitHub for any security reviews before depositing large amounts.
Swaps are non-custodial in the usual DEX model, meaning you keep your tokens in your own wallet until you trade. Risks still include smart-contract bugs, impermanent loss for liquidity providers, malicious or low-quality tokens and phishing sites. Always check the address you are using. The site's disclaimer says it offers no investment advice, and no incidents are mentioned publicly.
