What Is Orca on Solana? Whirlpools DEX and ORCA Token Guide

Orca is a decentralized exchange on Solana that runs on concentrated liquidity pools called Whirlpools, where liquidity providers choose a price range instead of spreading capital across every possible price. It is one of the largest venues on the network: DefiLlama shows about $8.0 billion in 30-day trading volume and roughly $300 million in total value locked as of October 25, 2026. Most traders never visit Orca directly; their swaps reach it through routers such as Jupiter, which split orders across the cheapest pools.

Key Facts

• Type: automated market maker (AMM) DEX on Solana, also deployed on Eclipse.
• Core product: Whirlpools, Orca’s concentrated liquidity pools, introduced in 2022.
• Volume: about $8.01 billion over 30 days to October 25, 2026 (DefiLlama).
• TVL: about $300 million on the same date.
• Average fee: DefiLlama records about $7.8 million in 30-day fees, about 0.10% of volume, far below memecoin-focused venues.
• Token: ORCA governs the protocol; stakers receive xORCA, funded by buybacks from a share of Whirlpools protocol fees (Orca docs).

How Whirlpools Work

In a classic AMM pool, your liquidity is spread from a price of zero to infinity, so most of it sits idle at prices the market never reaches. A Whirlpool lets you pick a range, for example SOL between $150 and $250. While the price stays inside that range, your capital earns fees as if it were a much larger position. When the price moves outside the range, your position converts entirely into one of the two tokens and stops earning until the price returns or you move the range.

This is why Orca can show high volume on modest liquidity: concentrated positions provide deep liquidity right around the current price. The flip side is that providing liquidity becomes an active job, and the classic risk of impermanent loss is amplified inside a narrow range.

Orca vs Other Solana DEXs

Pool design	Concentrated liquidity	Constant product (plus CLMM product)	Constant product
30-day volume (DefiLlama, 25.10.2026)	~$8.01B	~$5.75B	~$9.86B

The volume-to-TVL ratio tells the story. Orca turns over about 27 times its liquidity in a month, compared with about 5 times for Raydium AMM. Capital is working harder in concentrated pools, which is good for traders’ prices and demanding for LPs. For how Raydium’s pools differ, see what Raydium is.

Using Orca as a Trader

You can swap on Orca’s own site by connecting a Solana wallet, but in practice most volume arrives through aggregators. When you swap SOL for USDC on Jupiter, the route often includes an Orca Whirlpool because it offers the tightest price for that size. The practical takeaway: you rarely need to choose Orca yourself, but it is useful to recognise it in a route breakdown, and the general router logic is in what Jupiter Exchange is.

Limits and Risks

• Range management: a Whirlpool position out of range earns nothing and holds 100% of the weaker asset.
• Concentrated impermanent loss: narrow ranges magnify losses relative to simply holding.
• Smart contract risk: audits reduce but never remove the risk of a bug.
• Long-tail tokens: Orca lists permissionless pools too; a pool existing on Orca is not an endorsement of the token.

Orca and Memecoin Liquidity Like $DOLAN

Concentrated liquidity is mostly used for pairs with predictable ranges, like SOL/USDC. Memecoins such as DOLAN Duck ($DOLAN), a fair-launch SPL token with a 98.3M supply and roughly 10,700 holders, behave differently: their price can move 50% in a day, which pushes a narrow range out of bounds fast. That is why memecoin liquidity tends to sit in constant-product pools, where liquidity covers every price, even though it is less capital efficient. Understanding that trade-off helps explain why the same token can have very different depth on different DEXs, as covered in slippage on Solana memecoins.
