Sonex is a small decentralized exchange on the Soneium chain that aims to grow into a broader DeFi hub. TVL is low and no audits are listed, so treat it as an early-stage product.

Our verdict on Sonex

5.2/10

Sonex suits experienced DeFi users who want to try a native DEX on Soneium and accept early-stage risk. Its swap and pool tools are live, and the roadmap is ambitious. The main caveat is that TVL is only about $63.6K and DefiLlama lists no audits, so liquidity is thin and contract risk is unquantified. Roadmap items like lending and derivatives are unconfirmed. Keep position sizes small.

What is Sonex?

Sonex is a decentralized exchange on Soneium, the Ethereum layer-2 chain. It was listed on DefiLlama in January 2025 under the Dexs category. The app offers swaps, an explore page and liquidity pools.

The project's description pitches a larger vision: an "Alpha Hunting Ecosystem Aggregator" built on zk co-processors, decentralized storage and an AI routing terminal. The homepage roadmap lists swap and pools on testnet in late 2024, staking, lending and derivatives in early 2025, and community voting plus an order-book DEX in Q2 2025.

Current traction is modest. DefiLlama shows about $63.6K in TVL, down about 4.2% over seven days, no token and no audits. The homepage also says Sonex was a Soneium Spark Innovation Winner and that it closed a seed round, though public sources give no amounts or investors. The site copyright names SONEX Labs Limited.

How Sonex works

Sonex is a decentralized exchange. Users connect a wallet and swap tokens directly from their own wallet through smart contracts on Soneium, instead of depositing funds with a company. Prices come from liquidity pools, which hold pairs of tokens supplied by other users.

Liquidity providers deposit tokens into pools and typically earn a share of trading fees, but they carry risks such as impermanent loss and smart-contract bugs. The project does not say how Sonex splits fees or whether its pools follow a specific design.

The project also describes an AI routing terminal and zk co-processors as part of its longer-term plan. These are described at a high level only, so readers should treat them as stated goals until documentation confirms them.

Pros and cons

What we like

Focused on Soneium, giving users a native DEX on that chain
Offers both swap and pool functions in the live app
Publicly states a roadmap covering staking, lending, derivatives and an order-book DEX
Self-reports recognition as a Soneium Spark Innovation Winner
Non-custodial design typical of a DEX, so users trade from their own wallet

Watch out for

TVL is very small at about $63.6K, which usually means thin liquidity and larger price impact on swaps
DefiLlama lists no audits for the protocol
No token is listed, and the homepage mentions an X-Token without details
Roadmap items such as lending, derivatives and an order-book DEX are plans, and the project does not confirm they shipped
The AI routing and zk co-processor claims are described without technical documentation
Tied to a single chain, Soneium, so it depends on that ecosystem's activity

Sonex fees

Sonex does not publish swap fees, pool fee tiers or protocol fees. Users should expect to see the fee on the swap confirmation screen and in the pool pages inside the app before approving a transaction.

On any chain you also pay network gas fees on Soneium. Those depend on the network and are separate from whatever Sonex charges.

Is Sonex safe?

DefiLlama lists no audits for Sonex, and its homepage does not point to any. Smart-contract risk is therefore unquantified. Low TVL also means small liquidity pools that can be volatile and easier to manipulate.

Sonex is a non-custodial DEX, so you keep your keys, but you still bear smart-contract, pricing and impermanent-loss risk. Public sources report no hacks or incidents, and no regulatory status is given. Only use funds you can afford to lose and verify that you are on the official site.

6 steps

How to get started with Sonex

1
Check that DeFi trading is permitted where you live and that you understand the risks of small, unaudited protocols.
2
Set up a Web3 wallet that supports Soneium and add the network.
3
Bridge or acquire a small amount of ETH or tokens on Soneium to cover trades and gas.
4
Open the Sonex app from the official site and connect your wallet.
5
Use the Swap page with a small test amount and review the quoted price, fee and slippage before confirming.

Sonex FAQs

What is Sonex?

Sonex is a DeFi project on Soneium that offers token swaps and liquidity pools. Its description says it plans to grow into a wider ecosystem with staking, lending and other derivatives.

Which blockchain does Sonex run on?

Public sources list only Soneium. The app is built for that network, so you need a compatible wallet and funds on Soneium to use it.

Has Sonex been audited?

DefiLlama lists no audits for Sonex and its homepage does not mention one. Check the project's own documentation for any security reviews before depositing funds.

Does Sonex have a token?

DefiLlama shows no token for Sonex. The homepage references an X-Token section, but the project does not describe what it is or whether it is live.

Did Sonex win any awards?

The homepage says Sonex was recognized as a Soneium Spark Innovation Winner. That is a self-reported accolade and not a security guarantee.

How much liquidity does Sonex have?

Total value locked is about $63.6K and fell roughly 4.2% over seven days, according to DefiLlama. That is small, so slippage can be high on larger trades.
