Orca is a decentralized exchange (DEX) built on the Solana blockchain. Orca offers swaps, liquidity pool rewards, and yield farming. One of Orca’s notable features is its fair price indicator, which checks whether the quoted price for a given trade is within 1% of the current market rate on CoinGecko and whether slippage is less than 1%. If either of those checks are triggered, the user receives a rate or slippage warning and is prompted to reconfirm or cancel the trade.
