AUX Exchange Review – Simple Aptos DEX With Smart Tech, Little Use

What It Is

AUX Exchange launched recently on Aptos as a decentralized trading venue. It offers on-chain orderbook trades, swaps, limit orders, IOC orders - all executed from your wallet. The promise: zero fees, advanced order types, open-source code, and smart routing between pools and the orderbook.

AUX was designed to provide users with a seamless experience for trading within the growing Aptos ecosystem. Unlike many DEXs that rely on liquidity pools for trades, AUX uses a hybrid system that combines the benefits of both orderbooks and automated market makers (AMMs). The idea is to bring together the best of both worlds by leveraging liquidity from multiple sources to offer users the best trading experience.

Token Support and Markets

Only three assets are currently tradable - APT, USDC, and a staked APT variant. That creates just three trading pairs in total. You won’t find wide asset options here.

The focus on APT and USDC provides users with an initial base to conduct trades, but the lack of diversity in token options limits the appeal for more active traders or those looking to trade a variety of digital assets. There is also a noticeable lack of assets from other blockchain ecosystems, making AUX a niche platform compared to more established DEXs that offer a wider range of tokens across multiple blockchains.

Volume and Liquidity

24-hour volume ranges between 1,000 and 4,000 USD across trackers. That’s roughly 1k–4k USD in trades daily, with about 3–12 active pairs. Transactions number in the low thousands but represent tiny sums - this is a virtually unused platform.

AUX Exchange struggles with liquidity. Despite offering zero fees on trades, the lack of liquidity means that users are not able to execute large orders without experiencing slippage. This is especially problematic for those who wish to trade significant amounts of assets. While the zero-fee model may attract some users, it fails to compensate for the lack of active trading on the platform.

Fee and Order Model

AUX offers zero taker and maker fees via its orderbook. You pay only network gas. That’s rare in DEX design - but in this case, the zero-fee promise meets zero volume - you can’t spend what isn’t moving.

The zero-fee model is an attractive feature for users who are looking to save on transaction costs. However, with low liquidity and limited trading pairs, it’s unlikely that traders will be able to capitalize on this feature effectively. In a high-volume environment, zero fees would be incredibly beneficial, but AUX currently does not have the necessary infrastructure to support a thriving ecosystem of active traders.

Tech and Routing

Built with smart-order routing, it selects the best path - whether that’s an orderbook fill or pool swap. Liquidity may come from local pools or cross-platform bridges. The tech is sound - it just lacks users.

The smart-order routing system is designed to automatically find the most efficient way to execute a trade, whether it’s through the orderbook or through liquidity pools. This ensures that users receive the best possible price and minimal slippage, even with the platform’s limited liquidity. The use of cross-platform bridges allows AUX to tap into liquidity from multiple sources, making it a versatile exchange in terms of routing trades. However, this system is only effective if there is sufficient trading activity on the platform.

Security and Transparency

AUX is open-source and runs on audited Aptos smart contracts. Everything is on-chain and wallet-controlled. No custody, no hidden terms. If you like transparent code, this is clean - but low usage means less real-world testing.

The transparency of the platform is one of its strongest features. With open-source code and smart contracts that have been audited, users can trust that their funds are secure and that there are no hidden fees or malicious activities happening behind the scenes. However, because the platform is still in its early stages and has yet to gain widespread usage, it is difficult to gauge its true security in the real world. A larger user base would help identify any vulnerabilities or weaknesses in the system.

Pros and Cons

What works:

• True non-custodial DEX with wallet trading only
• No trading fees - only gas costs
• Supports advanced orders and smart routing
• Open-source and technically transparent

What doesn’t:

• Almost zero liquidity and user activity
• Only 3 tokens and 3 pairs available
• Zero-fee model isn’t useful when nobody trades
• Early stage tech - UI and community are still sparse

Final Thoughts

AUX Exchange is a neat concept - a non-custodial Aptos DEX with modern features and no fees. But the promise runs into reality: no volume, no liquidity, no momentum. It’s waiting for users.

If you’re an Aptos early adopter and love testing emerging tech, AUX is worth a look - just trade with tiny amounts. For everyone else, it’s a niche tool waiting for traction. Track its evolution, but don’t bank on volume yet.

At this point, AUX Exchange is more of a proof of concept than a functional exchange. It may hold potential as Aptos grows, but for now, it’s unlikely to become a go-to DEX for active traders. If you’re looking for a well-established exchange with solid liquidity, AUX may not be the best choice, but if you’re willing to experiment with an early-stage platform, it might be worth testing in small amounts.
