Orca

Orca is a Solana-native AMM built around concentrated-liquidity pools it calls Whirlpools, along with a swap interface that’s generally regarded as one of the more approachable in the ecosystem for people newer to providing liquidity directly rather than just swapping.

What it’s for

Like Raydium, Orca serves both traders swapping through its pools (directly or via an aggregator) and liquidity providers depositing into a specific price range to earn fees. Orca has put particular emphasis on tooling that shows LPs their expected fee income and impermanent loss exposure up front, rather than leaving that calculation to the user.

Reputation and track record

Orca has been part of the core Solana DeFi infrastructure for multiple years and is, like Raydium, a common liquidity source that swap aggregators route through. It has operated through several market cycles without a widely reported protocol-level exploit.

Risk considerations

The same core risks apply as with any concentrated-liquidity AMM: smart contract risk, and impermanent loss or out-of-range exposure for liquidity providers. If you’re new to providing concentrated liquidity specifically, start with a narrow amount of capital until you understand how range selection affects both fee income and your exposure to price movement — read our impermanent loss guide first.
