Decentralized Exchanges
Swap tokens directly from your wallet without a centralized order book or custodian.
Decentralized exchanges, or DEXs, let you swap one token for another directly from your own wallet. There’s no account to open and no custodian holding your funds — trades settle against on-chain liquidity pools or an on-chain order book, and you keep control of your assets until the moment a trade executes.
On Solana, most DEX volume runs through automated market makers (AMMs) like Raydium, Orca, and Meteora, plus aggregators like Jupiter that route your trade across multiple pools to find the best price. Aggregators exist because liquidity is fragmented across dozens of pools; routing through several of them at once usually beats trading on a single DEX directly.
How to evaluate a DEX
A few things actually matter when picking where to trade:
- Liquidity depth for your pair. Thin pools mean high price impact on anything beyond a small trade size. Check the quote before you confirm, not after.
- Track record. How long has the protocol been running, has its contracts been audited, and has it handled high-volume periods (token launches, volatile markets) without breaking?
- Fee structure. AMMs charge a swap fee that goes to liquidity providers; some also route through aggregators that add routing fees. These change often — check current rates in the app itself rather than trusting anything you read that’s more than a few months old.
- MEV exposure. Sandwich attacks and other MEV extraction are a real cost on any public blockchain with a mempool-like structure. Using an aggregator with MEV protection, and setting sane slippage tolerances, reduces this.
The main risks
Smart contract risk is the big one — a bug in an AMM’s code can be exploited to drain a pool. Depeg risk matters if you’re trading wrapped or liquid-staked assets, since their price can temporarily or permanently diverge from the underlying. And impermanent loss is a real cost if you provide liquidity yourself, not just trade — see our impermanent loss guide for the mechanics.
