Orca
A Solana AMM focused on UX, with the Whirlpools concentrated-liquidity design and a curated set of high-quality pools.
Orca launched on Solana in 2021 with a deliberately simple swap UI and an unusual emphasis on safer trading defaults. Whirlpools, its concentrated-liquidity AMM (similar to Uniswap v3), arrived in 2022 and is now the largest Solana AMM by TVL on many pairs.
Orca has been one of the more design-conscious projects in the Solana DeFi ecosystem, with pool curation, anti-MEV protection, and its own community-curated token list.
