Solana DEX Comparison: Orca, Raydium, Meteora, and More
Solana has dozens of DEXes, each with different pool architectures, fee models, and strengths. This guide covers the major ones and when to use each.
DEX Architecture Overview
| DEX | Pool Type | Best For | Fee Model |
|---|---|---|---|
| Orca Whirlpool | Concentrated Liquidity (CLMM) | Major pairs, tight spreads | Dynamic (1-200 bps) |
| Raydium CLMM | Concentrated Liquidity (CLMM) | Major pairs, deep liquidity | Dynamic (1-100 bps) |
| Raydium AMM V4 | Constant Product (x*y=k) | Legacy pairs | Fixed 25 bps |
| Raydium CPMM | Constant Product | New token launches | Fixed 25 bps |
| Meteora DLMM | Dynamic Liquidity (Bin-based) | Volatile pairs, new tokens | Variable by bin step |
| Meteora Dynamic | Constant Product (Mercurial) | Stablecoin pairs | Variable |
| PumpSwap | Constant Product | Memecoins, graduated tokens | Fixed |
| Phoenix | Central Limit Order Book | Large orders, institutional | Maker/taker |
| Saber | StableSwap (Curve-style) | Stablecoin swaps | 1-4 bps |
Concentrated Liquidity (CLMM)
Orca Whirlpool and Raydium CLMM are the most popular DEXes on Solana for major trading pairs.
How It Works
Liquidity providers (LPs) concentrate their capital within a specific price range instead of spreading it across 0 to infinity. This means:
- Better prices for traders — more liquidity at the current price
- Higher capital efficiency — LPs earn more fees per dollar deposited
- Tighter spreads — especially for high-volume pairs like SOL/USDC
Key Differences
| Orca Whirlpool | Raydium CLMM | |
|---|---|---|
| Tick spacing | Configurable (1, 8, 64, 128) | Configurable |
| Fee tiers | 1, 2, 4, 8, 16, 64, 100, 200 bps | 1, 2, 4, 5, 20, 100 bps |
| Liquidity depth | Deepest for SOL/USDC | Strong for SOL pairs |
| Ecosystem | Whirlpool SDK, Orca UI | AcceleRaytor, Raydium UI |
When to use CLMM: Major token pairs, stablecoin swaps, any trade where tight spreads matter.
Constant Product AMMs
The classic x * y = k model. Simple, battle-tested, and still widely used.
Raydium AMM V4
The original Raydium AMM. Uses an on-chain order book integration with the now-deprecated Serum. Still has deep liquidity for many pairs due to legacy pools.
Raydium CPMM
Raydium's newer constant product implementation. Simpler than V4 — no order book dependency. Most new Raydium pools use this format.
PumpSwap
PumpSwap is where tokens "graduate" from the Pump.fun bonding curve. Once a token reaches a market cap threshold on Pump.fun, it migrates to a PumpSwap constant product pool. This is the primary venue for memecoin trading on Solana.
When to use constant product: Memecoins, new tokens, any pair where CLMM pools don't exist.
Bin-Based Liquidity (Meteora DLMM)
Meteora's DLMM (Dynamic Liquidity Market Maker) uses a bin-based system instead of ticks or curves.
How It Works
- Price range is divided into discrete bins (e.g., bin step of 5 = 0.05% per bin)
- LPs deposit into specific bins
- Swaps move through bins sequentially — the active bin has zero slippage
- As the price moves, the active bin shifts
Why DLMM Matters
- Zero slippage within the active bin — if enough liquidity exists in the current bin, the swap fills at the exact bin price
- Flexible LP strategies — spot, curve, bid-ask distributions
- Popular for volatile pairs — the bin system handles rapid price movement well
When to use DLMM: Volatile tokens, new launches, pairs with active LP management.
Order Books (Phoenix)
Phoenix is a fully on-chain central limit order book (CLOB). Unlike AMMs, it matches discrete limit orders.
Key Properties
- Maker/taker fee model
- Limit orders, market orders
- Best for large orders that would cause significant AMM slippage
- Lower adoption than AMM-based DEXes
When to use Phoenix: Large orders, institutional trading, when you need limit order support.
StableSwap (Saber)
Saber uses a Curve-style StableSwap invariant optimized for assets that should trade near 1:1.
How It Works
The StableSwap curve provides extremely low slippage for swaps between pegged assets (USDC/USDT, mSOL/SOL, etc.). It uses Newton's method to solve the invariant, which is more compute-intensive but gives much better prices for stable pairs.
When to use Saber: Stablecoin swaps (USDC/USDT), LST swaps (mSOL/SOL, jitoSOL/SOL).
How Routing Across DEXes Works
The best price for a given swap depends on:
- Pool liquidity — how much is available at the current price
- Fee structure — CLMM fees vary by pool, AMMs are typically fixed
- Price impact — how much your order moves the price
- Current pool state — reserves, tick positions, active bins
A swap router checks all available pools for your token pair, computes the expected output for each, and picks the best one. For larger orders, it may split across multiple pools.
Venum evaluates all major DEXes simultaneously using real-time pool state — quotes return in under 10ms.
Summary
| If you're trading... | Best DEX type | Why |
|---|---|---|
| SOL/USDC, ETH/USDC | CLMM (Orca, Raydium) | Tightest spreads, deepest liquidity |
| USDC/USDT, mSOL/SOL | StableSwap (Saber) | Near-zero slippage for pegged assets |
| New memecoins | AMM (PumpSwap, Raydium CPMM) | Where new tokens list first |
| Volatile mid-caps | DLMM (Meteora) | Bin-based precision, active LP management |
| Large orders ($100K+) | CLOB (Phoenix) | Limit orders, minimal market impact |
Don't pick one DEX — use a router that checks them all. That's what Venum's quote endpoint does.
