Hey Product Hunt, we're ZNG Labs ā the team behind NEXA EXCHANGE, a non-custodial DEX on Solana.
The idea is simple: trading on-chain should feel as smooth as a centralized exchange, without ever handing over your keys. So we built:
⢠Swaps across 600+ tokens with best-price routing, at a flat 0.05% fee
⢠On-chain limit orders that fill at your exact price with 0% slippage ā cancel anytime, funds stay in your wallet
⢠NX points on every swap and every filled order
⢠A free Telegram bot for price alerts, with one tap to trade
Today's milestone: NEXA is now a mobile app published on the Solana dApp Store for Seeker, so the whole flow works from your phone, wallet included.
What's next: MEV-protected private orders and confidential swaps ā and we're open-sourcing that work as a reusable kit for other Solana builders (github.com/ZNGLABS/confidential-swap-kit).
Happy to answer anything about the architecture, the routing, or how we handle non-custodial limit orders. Feedback very welcome, especially the critical kind.
Report
The 0% slippage limit orders are a solid touch for anyone trading smaller caps on Solana, and Jupiter routing under the hood means prices are usually tight. Wish there was a bit more clarity on how NX points accumulate, but overall swaps have been quick and clean.

@kumsalukh1Ā Thanks for the kind words - glad the routing and execution felt tight for you. NX points accrue automatically in the background on every swap and every filled limit order, no extra step needed, and your running total shows up on the Portfolio page. We're working on making that breakdown clearer for Season 1 so it's easier to see exactly how points build up.

Love how clean the swap interface is, especially the way slippage settings sit right next to the route preview so you can adjust without losing context. The 0.05% fee plus Jupiter routing is a really solid combo for anyone trading on Solana.

@saliha467236Ā Thank you, that's exactly the experience we were aiming for - keeping the route preview and slippage controls in the same view so there's no guessing what a swap will actually execute at. Jupiter's routing does most of the heavy lifting on pricing, and we kept the fee flat at 0.05% so it stays predictable across every token pair. Really glad that combination is landing well for you.

Something we think about a lot when we talk about what's next: on Solana (and most chains), every swap is public by default. Anyone can watch a wallet's trade sizes, routes, and timing in real time. That transparency is part of why on-chain trading is verifiable at all, but it also means strategies and position sizes are visible to anyone watching.
That's the direction we're building next: confidential swaps, where a trade still settles on-chain and stays non-custodial, but the amount and route aren't broadcast publicly. We're building the core of it as an open-source kit so other Solana teams can use the same building blocks - github.com/ZNGLABS/confidential-swap-kit if you want to follow along.
Curious how people here think about the transparency/privacy trade-off on-chain - feels like an underrated design question for DeFi in general. And if you haven't tried NEXA EXCHANGE yet, it's live at nexa-exchange.fr
