Orca is a decentralized exchange (DEX) on Solana where you swap tokens straight from your wallet and earn fees by providing liquidity. It’s best known for Whirlpools, its concentrated-liquidity pools, and for a clean interface aimed at people who aren’t DeFi specialists. Much of Orca’s volume comes through aggregators such as Jupiter, so many Solana users trade on Orca without visiting it. So what is Orca in late 2026? It’s one of Solana’s core liquidity venues, and since 7 October 2026 it’s part of a merged company called Formation, combining Orca’s trading infrastructure with Loopscale’s lending. The ORCA token covers both. Here’s the history, how Whirlpools work, the token changes, and a practical walkthrough.
You’ll find this and every related walkthrough in our DeFi hub.
Key takeaways
- Co-founded by Grace “Ori” Kwan and Yutaro Mori. Orca launched on Solana in February 2021. Grace goes by “Ori,” so some older pages, including a previous version of this one, list her as “Ori Kwan.”
- Whirlpools let liquidity providers concentrate capital in a price range, earning more fees per dollar while in range and nothing when out of range.
- In 2025 the DAO burned 25 million ORCA, cutting total supply from 100 million to 75 million. A share of Whirlpool protocol fees funds ORCA buybacks for xORCA stakers.
- Orca and Loopscale merged into Formation in October 2026. Existing Whirlpool positions were unaffected, and ORCA is the token for the combined company.
- Orca says it has processed over $550 billion in trading volume since 2021.
History
2021, launch: Grace Kwan (previously at IDEO and Coursera) and Yutaro Mori (who had worked on Ethereum 2.0 and UMA) launched Orca in February 2021 under the slogan “human-centered DeFi.” Unlike many DEXs of the time, it focused on plain-language interfaces and protections such as a Fair Price Indicator that warned when a swap price was far from the market. The ORCA token launched in August 2021. In September 2021 Orca raised an $18 million Series A led by Polychain and Placeholder, with participation from Three Arrows Capital among others.
2022, Whirlpools and surviving FTX: Whirlpools, Orca’s version of Uniswap v3-style concentrated liquidity, launched in March 2022 and became the core product. When FTX and Alameda collapsed in November 2022, Solana DeFi lost its biggest market maker. Orca kept running and became one of the main sources of liquidity for the recovering ecosystem.
2023–2025, aggregator era and token reforms: as Jupiter became Solana’s default router, Orca’s role shifted to being deep “back-end” liquidity for SOL, stablecoins and liquid-staking tokens. The DAO voted in 2025 to burn 25 million ORCA from the treasury and to use 20% of Whirlpool protocol fees to buy ORCA for an xORCA staking reserve.
October 2026, Formation: Orca merged with Loopscale, a Solana lending protocol formerly called Bridgesplit, to form Formation, based in New York. Loopscale co-founder Luke Truitt is CEO. The company says it plans to combine trading, credit and vaults and to finance “frontier” assets such as AI and energy infrastructure. Both apps keep running, and Loopscale points convert into the ORCA ecosystem rather than a new token. Note that Loopscale suffered a roughly $5.8 million exploit in April 2025, two weeks after launch. The attacker returned the funds under a bounty deal, but the incident is relevant history for anyone now using the combined platform.
Key features
- Whirlpools: concentrated liquidity across several fee tiers, from very low fees for stablecoin pairs to higher fees for volatile tokens.
- Positions as NFTs: each liquidity position is a token in your wallet that you can view, move or close.
- Clean swap interface: price-impact warnings and clear slippage controls.
- Permissionless pools: anyone can create a pool, which also means scam tokens can have pools. Always verify the mint address.
- Developer SDKs: Whirlpools are open source and widely integrated by aggregators, wallets and vault strategies.
Background reading: what is a liquidity pool.
How concentrated liquidity works (worked example)
Say SOL trades at $150 and you provide $1,000 to a SOL/USDC Whirlpool:
- Wide range ($75–$300): you stay in range through big moves, but your capital is spread thin and earns modest fees.
- Narrow range ($140–$160): your $1,000 acts like many times that amount in a full-range pool, so you earn far more fees while SOL stays between $140 and $160.
- If SOL drops to $130: your position has been fully converted into SOL, the asset that fell, and it stops earning until the price returns or you reset the range.
That conversion is impermanent loss in concentrated form, and narrow ranges magnify it. Read impermanent loss explained before providing liquidity.
How to use Orca (step by step)
Swapping
- Install a Solana wallet such as Phantom or Solflare and fund it with SOL. See our Phantom review.
- Go to orca.so by typing it in or using a bookmark, and click Connect.
- Choose the tokens. For anything other than major assets, paste the mint address and check that the token shows as verified.
- Check price impact and set slippage (around 0.5% for major pairs), then confirm in your wallet. Keep a small SOL balance for fees.
Providing liquidity in a Whirlpool
- Open Pools, choose a pair and compare fee tiers by volume and TVL.
- Set a price range. Beginners should start wide.
- Deposit both tokens in the ratio shown and approve. You’ll receive a position NFT.
- Check it regularly: collect fees, and close or re-range positions that drift out of range.
Check Orca’s terms for regional restrictions before using it.
Should you use Orca directly or through an aggregator?
- Just swapping a common pair (SOL, USDC, major LSTs)? An aggregator like Jupiter will usually route through Orca anyway when it has the best price, and it compares other venues too.
- Providing liquidity? Use Orca directly. Aggregators don’t manage LP positions, and Orca’s interface shows range, fees earned and in-range status.
- Trading a token that only has an Orca pool? Going direct lets you see the pool’s depth and creation date, a quick way to spot thin or suspicious pools.
- Using a vault or auto-rebalancer? Several Solana vault protocols manage Whirlpool ranges for you for a fee. They add another layer of smart-contract risk.
Tokenomics
| Item | Detail |
|---|---|
| Original max supply | 100 million ORCA |
| 2025 burn | 25 million ORCA from the community treasury, leaving 75 million total |
| Buybacks | 20% of Whirlpool protocol fees buy ORCA for the xORCA staking reserve |
| xORCA | Staked ORCA that receives buyback flows and carries governance weight |
| Utility after the merger | Token for the whole of Formation (Orca plus Loopscale) |
Check the current supply and staking terms in Orca’s official docs, because the merger may bring further changes.
Orca vs Raydium
| Orca | Raydium | |
|---|---|---|
| Core design | Concentrated liquidity (Whirlpools) | Standard AMM plus concentrated pools |
| Strength | Deep majors and stablecoin liquidity, clean UX | Memecoin launches and LaunchLab, high retail volume |
| Token value flow | Fee-funded ORCA buybacks to xORCA | Fee-funded RAY buybacks |
| Who it suits | LPs and swappers of established assets | Traders chasing new tokens |
In practice, Jupiter splits trades across both, and you’ll often get the best price by swapping there. Compare more venues in best Solana DeFi projects.

FAQ
Is Orca safe to use?
Orca’s Whirlpool contracts have been audited and have run since 2022 without a major exploit of user funds, which is a solid record by DeFi standards. Risks remain: smart-contract bugs, fake tokens in permissionless pools, phishing sites copying orca.so, and impermanent loss for liquidity providers. Use the official URL, verify mint addresses and start small.
What is the Orca and Loopscale merger?
Announced on 7 October 2026, the merger combines Orca’s DEX with Loopscale’s lending protocol under a new New York-based company, Formation. Loopscale’s Luke Truitt is CEO. Existing Whirlpool positions, fees and rewards stayed as they were with nothing to migrate, and ORCA became the token for the combined platform. Financial terms were not disclosed.
Is ORCA a good investment?
ORCA’s case rests on Orca’s fee revenue (20% of protocol fees fund buybacks), a smaller supply after the 2025 burn, and whatever Formation can add through lending. Risks include low direct-swap traffic, heavy competition, and execution risk from the merger. It’s a small-cap DeFi token, so size any position accordingly.
How do I use Orca on Solana?
Connect a Solana wallet such as Phantom or Solflare at orca.so, pick the tokens, check price impact and slippage, and confirm. To earn fees, open a Whirlpool position with a price range. Wider ranges are safer for beginners. Always keep a little SOL for transaction fees and verify token mint addresses before trading.
