Orca

Orca is a decentralized exchange and automated market maker (AMM) on Solana. Its core product is Whirlpools, an open-source concentrated liquidity protocol that lets liquidity providers (LPs) earn trading fees on their chosen price ranges while traders swap tokens. Orca launched in early 2021 and is one of Solana's longest-running DeFi protocols. It now describes itself as "Solana's premier liquidity layer" and has moved beyond spot swaps into token launches, regulated tokenized assets and fee-funded staking.

What Orca does

Orca connects two groups. Traders want to swap SPL tokens with low slippage, and liquidity providers want to earn fees on idle capital. LPs deposit token pairs into pools and traders swap against them, paying a fee on each trade that mostly goes to the LPs. On Solana, network fees for these transactions are typically fractions of a cent.

Orca's website lists more than $500 million in cumulative fees earned by LPs, more than $500 billion in cumulative trading volume, total value locked of more than $236 million, and daily volume above $250 million. These are self-reported figures and change over time. The site also says Orca has gone more than five years without a security exploit, and it names several major token launches on its pools, including PayPal's PYUSD, Coinbase's cbBTC and Jito's JTO.

Most of Orca's volume comes through aggregators rather than its own interface. Independent reviews note integrations with routers such as [[PROJECT:219]], Titan and DFlow, so trades from other apps often settle in Orca pools.

How Whirlpools works

Orca started as one of Solana's first constant-product AMMs, where liquidity is spread across every possible price. In 2022 it introduced Whirlpools, a concentrated liquidity design in which each LP picks the price range where its capital is active. Liquidity near the current price earns more fees per dollar deposited, and traders get deeper books where most trading happens. The tradeoff is that a position stops earning once the price leaves its range, and concentrated positions are more exposed to impermanent loss. Orca's docs explain both full-range and custom-range positions for LPs who want to limit how much they have to manage.

The Whirlpools program runs on Solana mainnet at whirLbMiicVdio4qvUfM5KAg6Ct8VwpYzGff3uctyCc and is also deployed on devnet. The Rust contract is open source. Developers can build on it with TypeScript and Rust SDKs (@orca-so/whirlpools and orca_whirlpools), lower-level generated clients, and core math libraries, and Orca also publishes a public REST API.

Fees

Each pool has a fee tier. Independent reviews list common tiers of 0.01%, 0.05%, 0.30% and 1.00%, with some pools going up to 2%. Coin Bureau's review says trading fees are split roughly 87% to LPs, 12% to the protocol treasury and 1% to a climate fund.

Orca also offers Adaptive Fee pools, which add a variable component to the base fee. The extra fee rises with price movement, measured partly by how many tick groups a trade crosses, and falls back toward the base rate when markets are calm. The goal is to pay LPs more during the volatile periods when they take the most risk. Orca's docs state that adaptive fees do not guarantee higher returns and do not remove impermanent loss, and fixed-fee pools remain available.

Other products

Wavebreak. Wavebreak is Orca's token launchpad. New tokens are sold on a bonding curve, and once a sale completes, the token "graduates": SolanaFloor reports that 84 SOL and part of the token supply are seeded into a Whirlpool with locked liquidity owned by the creator. To cut down on sniping, Wavebreak uses CAPTCHA checks and per-transaction purchase caps. It also pays a daily reward to traders based on their volume.

Permissioned pools for tokenized assets. In May 2026 Orca launched permissioned pools that restrict certain assets to approved investors, CoinDesk reported. Eligibility rules are enforced onchain and set by the issuer, and users must complete KYC before they can buy, hold or trade the restricted tokens. The first issuer was commodity tokenization firm Streamex with GLDY, a gold-linked security. Orca's X account has since announced that DAWN's USD.infra real-world asset token is coming to the platform. Orca has also publicly welcomed the SEC's September 2026 exemption for onchain trading of tokenized securities, crediting the Solana Policy Institute's "Project Open" work.

Portfolio tools. The Orca app includes a portfolio dashboard for tracking and compounding positions, a position simulator for estimating returns before depositing, and managed vault strategies.

ORCA token, xORCA and governance

The ORCA governance token (mint orcaEKTdK7LKz57vaAYr9QeNsVEPfiu6QeMU1kektZE, [[TOKEN:orcaEKTdK7LKz57vaAYr9QeNsVEPfiu6QeMU1kektZE]]) launched in August 2021. Orca had run without a token before then, supported at first by a Solana Foundation grant. Under Orca's governance model, ORCA and xORCA holders can submit and vote on proposals covering protocol upgrades, fee parameters, treasury spending and governance rules. An elected DAO Council carries out routine decisions and approved proposals, and holders can vote to replace it. Voting takes place on Realms.

xORCA is Orca's liquid staking token. Staking ORCA mints xORCA. Protocol fees then buy ORCA and add it to the staking vault without minting new xORCA, so each xORCA can be redeemed for more ORCA over time. According to the docs, 40% of the protocol's share of fees goes to these purchases. Unstaking starts a 7-day cooldown, during which the holder receives a claim-ticket NFT and the redemption rate is locked. xORCA also gives boosted voting power.

In August 2025, the DAO put forward a treasury proposal to use up to about 55,000 SOL from the treasury over 24 months for ORCA buybacks and for staking to an Orca validator. Daily purchases would be capped at 2% of ORCA's 30-day average trading volume, and the Council committed to publishing quarterly reports.

Security

The Whirlpools repository lists six audits: Kudelski Security (January 2022), Neodyme (May 2022), OtterSec (August 2024), and Sec3 (February, June and August 2025). Orca's docs say the xORCA staking contract is open source, audited by Sec3, and, like Whirlpools, can be upgraded only by a 3-of-5 multisig. Orca has run a bug bounty on Immunefi since May 2022, with a maximum payout of $500,000, and reviews report no protocol-level smart contract exploits since launch.

Team and history

Orca was co-founded by Yutaro Mori and Grace Kwan, who first worked under the pseudonyms "YM" and "Ori" before revealing their identities in June 2021. The project began as a response to high fees and congestion on Ethereum DEXs and launched on Solana in February 2021. Michael Hwang was CEO as of May 2026, when CoinDesk quoted him saying Orca had "spent five years building the liquidity infrastructure that Solana's market structure runs on." Nathan Davis was named as CEO in earlier coverage of the Wavebreak launch. Orca's leadership also includes a Chief Legal Officer, reflecting its growing focus on institutional and regulated markets.

Place in the Solana ecosystem

Orca is one of Solana's main sources of AMM liquidity. Because aggregators route trades through its pools, many new tokens, stablecoins and wrapped assets end up with Whirlpools liquidity. Its recent work on launches, adaptive fees, fee-funded staking and permissioned pools for regulated assets moves Orca from a retail swap interface toward general liquidity infrastructure. It competes directly with other Solana AMMs, and an ARK Invest analysis from July 2026 argued that Orca and Raydium face competitive pressure from fragmenting liquidity.
