Raydium and Orca are the two dominant DEXes on Solana, but they work very differently under the hood. If you're building a trading bot, analytics dashboard, or liquidity monitoring system, understanding these differences determines your strategy.

AMM Mechanics: Why It Matters for Bots

Raydium: Constant Product + Concentrated

Raydium's legacy pools use the classic x * y = k formula. Newer pools use concentrated liquidity (CLMM). The key for bots: Raydium is where Pump.fun tokens "graduate" to — when a bonding curve reaches 100%, liquidity migrates to a Raydium pool. This is a massive event for snipers.

Raydium events you want to monitor:

Pool Create: New liquidity pool deployed (including Pump.fun migrations)
Add Liquidity: LP tokens minted, pool TVL increases
Remove Liquidity: LP withdrawal — potential rug signal
Swap: Token exchange (the core trading event)

Orca: Whirlpools (Concentrated Liquidity)

Orca uses concentrated liquidity exclusively via their "Whirlpool" system. LPs choose price ranges, which creates deeper liquidity at active price levels but can lead to thinner liquidity outside ranges.

Orca events relevant to bots:

Open Position: New LP position in a specific tick range
Close Position: LP exits their range
Swap: Similar to Raydium but with tick-based price impact

Which to Monitor for Your Use Case

Token Launch Sniping → Raydium

If you're sniping new tokens, Raydium is non-negotiable. Pump.fun migrations land exclusively on Raydium. You need to detect the pool creation event and execute a buy in the same slot.

Established Token Trading → Both

For trading established tokens (SOL/USDC, BONK/SOL, etc.), both DEXes have deep liquidity. Jupiter routes through both automatically. Monitor both for the most complete picture.

Liquidity Analysis → Both (Different Insights)

Raydium shows raw pool depth. Orca shows where LPs concentrate their capital. Together, they give you a complete view of Solana DEX liquidity.

Copy Trading → Raydium + Jupiter

Most whale activity on new tokens happens on Raydium (direct) or Jupiter (aggregated). Orca activity tends to be more sophisticated LP management rather than speculative trading.

gRPC Data Availability

Subglow currently offers server-side filtering for Raydium and Jupiter. Orca Whirlpool support is on the roadmap. For now, the practical approach is:

Raydium: Full pre-parsed support via Subglow — pool creates, swaps, liquidity events
Jupiter: Full pre-parsed support — all aggregated swaps regardless of underlying DEX
Orca: Monitor via Jupiter filter (Orca-routed swaps appear in Jupiter data) or use raw gRPC with manual parsing

The Bottom Line

For most Solana trading bots in 2026, Raydium is the primary DEX to monitor — it has the highest volume, receives Pump.fun migrations, and has the most diverse token pairs. Orca matters more for established tokens and sophisticated LP strategies. Jupiter ties them both together as the aggregation layer.

If you're building today, start with Raydium + Jupiter filters through Subglow. That covers 80%+ of actionable Solana DEX activity with pre-parsed data and sub-5ms delivery.
