Four Questions I Ask Before Using a Solana DEX

I've watched enough financial markets to know that the biggest number isn't always the most useful number.

That's particularly true in crypto.

When I started looking more closely at Solana's decentralized exchange ecosystem, I noticed how easy it is to compare platforms using daily volume alone. But volume is only part of the picture. A DEX can process significant activity while still offering poor execution for the particular asset and order size a trader cares about.

A recent Crypto.news article made this point particularly well. Its guide, "Four things worth knowing before choosing a Solana DEX," examines liquidity, fees, trading architecture and custody instead of treating volume as the entire story: https://crypto.news/four-things-worth-knowing-before-choosing-a-solana-dex/

The first question I would ask is simple: Can this DEX actually handle my trade?

That means looking at the depth of the specific pair rather than simply checking the platform's overall volume. A venue with huge activity in SOL and a handful of major pairs may not have comparable liquidity for a smaller token.

The second question concerns the real cost of execution.

Solana's network fees are generally low, but I wouldn't stop there. A trader can also encounter venue fees, spreads, slippage and priority fees. During periods of congestion, paying for transaction priority can become a meaningful part of the cost.

The third question is about the trading mechanism.

An AMM and an order book approach the market differently. With an AMM, the available pool reserves determine pricing and larger trades can create greater price impact. Order books depend on bids and offers from market participants, which can provide useful depth when there's strong activity but may be thinner for less popular markets.

The fourth question is the one I think people sometimes overlook: Where are my assets actually going?

The fact that a platform operates on Solana doesn't automatically tell me how custody works. I want to know whether assets remain under my control through smart contracts or whether an intermediary takes custody at some stage.

That distinction matters because execution and custody are separate questions.

A DEX can offer excellent execution while presenting a particular custody structure, and a platform with a different architecture may make different tradeoffs. I wouldn't want to discover those differences only after something goes wrong.

From my perspective, choosing a Solana DEX is less about finding the platform with the biggest headline number and more about matching the venue to the trade.

The article I mentioned is useful precisely because it approaches the subject from that practical angle. For anyone researching Solana DEXs, I'd keep it alongside the platform's own documentation and current liquidity data rather than relying on reputation alone.
