Best DEX by Chain: Decentralized Exchanges on the Rails We Benchmark
A decentralized exchange (DEX) lets you swap tokens straight from your own wallet, on-chain, with no company holding your funds. Here are the leading DEXs on each of the chains we benchmark for x402 settlement, so you can see where to trade on the same rails that carry agentic payments.

Verdict: Match the DEX to the chain: Tinyman on Algorand, Jupiter on Solana, Aerodrome on Base, and Stellar's built-in SDEX
Each chain has a clear leader. On Algorand, Tinyman is the main DEX, and the chain's instant, sub-cent finality makes swaps fast and effectively free to settle. Solana routes most swaps through Jupiter; Base is led by Aerodrome; and Stellar is the outlier with an order-book DEX built into the protocol itself. Pick by where your assets and liquidity already are.

Algorand DEXs
Tinyman AMM
The largest DEX on Algorand and the one most people start with. A classic automated market maker (swap against pooled liquidity), plus liquid-staking and a token launchpad.
Pact AMM
Second major Algorand AMM, with stable-swap pools tuned for like-for-like pairs (for example USDC to USDt).
Vestige Aggregator
Routes a swap across Tinyman, Pact and others for the best price, and is the go-to analytics dashboard for Algorand DeFi.
Solana DEXs
Jupiter Aggregator
The default swap venue on Solana. It routes across every major pool for the best fill, so most Solana swaps flow through it.
Raydium AMM
One of the deepest liquidity sources on Solana and a primary launch venue for new tokens.
Orca AMM
Concentrated-liquidity AMM known for a clean interface and efficient pricing.
Base DEXs
Stellar DEXs
Stellar SDEX Order book (native)
Stellar is unusual: it has an order-book DEX built into the base protocol (the SDEX), so trades settle at the ledger level. StellarX and Lobstr are popular front-ends onto it.
Soroswap AMM
An AMM built on Soroban, Stellar's smart-contract layer, adding pooled liquidity alongside the native order book.
DEX vs CEX: which should you use?
They solve different problems. A centralized exchange (CEX) is the easiest way to move between dollars and crypto, with deep liquidity and a familiar account, but the operator holds your funds. A DEX keeps you in custody the whole time and lets you trade any on-chain token permissionlessly, at the cost of managing your own wallet and paying network fees. Most active traders use both: a CEX to get in and out of fiat, a DEX for self-custody and long-tail tokens. If you are choosing a CEX, our best US exchange ranking compares them on measured cost and API speed.
Why these chains?
This list is scoped to Algorand, Solana, Base and Stellar on purpose: they are the same rails we measure for x402 agentic payments. The property that makes a chain a good x402 rail, fast and cheap settlement that reaches finality quickly, is the same property that makes it pleasant to swap on. Algorand stands out on both counts, with instant deterministic finality and fees that round to a fraction of a cent.
Common questions
What is a DEX (decentralized exchange)?
A DEX is an exchange that runs as on-chain code rather than a company. You trade directly from your own wallet, keeping custody of your coins the whole time, and the swap settles on the blockchain. There is no signup, no account, and no custodian holding your funds, which is the opposite of a centralized exchange (CEX) like Coinbase or Kraken.
CEX vs DEX: what is the difference?
A centralized exchange (CEX) is a company that holds your funds and matches trades on its own servers: easy on-ramps, fiat, and deep liquidity, but you trust the operator with custody. A DEX is smart-contract code you trade against directly from your wallet: you keep custody and can trade any listed token permissionlessly, but you handle your own keys and pay network gas. Many active traders use a CEX to get in and out of dollars and a DEX for on-chain and long-tail tokens.
What is the best DEX on Algorand?
Tinyman is the largest and most widely used DEX on Algorand, an automated market maker where you swap against pooled liquidity. Pact is the other major AMM (with stable-swap pools), and Vestige aggregates across both to find the best price. Because Algorand settles with instant, sub-cent finality, swaps confirm quickly and fees are effectively rounding error.
What are the top DEXs on Solana, Base, and Stellar?
On Solana, Jupiter is the default aggregator (most swaps route through it), with Raydium and Orca as the deepest AMMs. On Base, Aerodrome leads by liquidity, with Uniswap widely used. On Stellar, the DEX is built into the protocol itself (the SDEX order book, reached through front-ends like StellarX), with Soroswap adding AMM-style pools on Soroban.
How do DEXs relate to x402 and agentic payments?
They run on the same rails. The chains we benchmark for x402 settlement (Algorand, Base, Solana, Stellar) are the same chains these DEXs live on, and the property that makes a chain good for x402, fast cheap final settlement, also makes it good for on-chain swaps. As AI agents start paying per request over x402, the ability to hold and swap stablecoins on-chain through a DEX is part of the same self-custody stack.
