Orca is a decentralized exchange (DEX) on Solana, known for its beginner-friendly interface and for concentrated liquidity via so-called Whirlpools. Users swap tokens and can provide liquidity within self-chosen price ranges.

Whirlpools are Orca's concentrated-liquidity pools. Instead of spreading capital across the entire price curve, providers deposit it within a self-chosen range — where it earns fees more concentrated, but must be managed more actively.

What are permissioned pools on Orca?

Permissioned pools let issuers of regulated real-world assets control who may trade on the secondary market (via Token-2022 Default Account State and an on-chain KYC layer). See our news on this.

How does Orca differ from Raydium?

Both are AMMs on Solana. Orca focuses strongly on concentrated liquidity (Whirlpools) and usability; Raydium also offers classic pools and token-launch tools. Aggregators like Jupiter use both as a liquidity source.

Orca explained: the concentrated-liquidity DEX (Whirlpools) on Solana

Orca is one of the most established decentralized exchanges on Solana and is considered especially beginner-friendly — while running advanced liquidity mechanics in the background.

In plain terms: Orca is a decentralized exchange on Solana. You swap tokens directly from your wallet, and if you want, you provide liquidity within a chosen price range and earn a share of the fees.

What Orca offers

Whirlpools (concentrated liquidity): Orca’s core. Liquidity providers deposit capital within self-chosen price ranges — higher fee efficiency, but more active management and impermanent-loss risk.
Simple swap: token swaps with a clear, beginner-friendly interface.
Permissioned pools: for regulated real-world assets where issuers control access (see Orca permissioned pools).

How Orca fits the ecosystem

Like Raydium, Orca is a liquidity source, not an aggregator. A swap via Jupiter can run partly through Orca Whirlpools. Trading directly on Orca is mainly worthwhile for targeted pool interaction or providing liquidity.

Risks to keep in mind

Impermanent loss with concentrated liquidity, especially when the price leaves the chosen range.
Smart-contract risk as with any DeFi protocol.
