Price

Price is an oracle design built on Uniswap V3 and developed by the Wonderland team, supplying time-weighted average price feeds to DeFi protocols. It closes two mechanism gaps in native TWAPs: liquidity is unpredictable, so the observation series can break once market makers exit, and multi-block attacks let a block proposer move prices across consecutive blocks, distorting a short-window TWAP. Price requires the pool to hold a full-range liquidity position so the feed cannot be interrupted by liquidity withdrawal, and directs part of the fees earned by that pool to keeping the oracle running, including keeper gas and expanding observation cardinality.

On top of that, the design adds a delay of about two minutes along with an automated job that detects suspicious spikes in price and volume; if the signals indicate a potential multi-block exploit it corrects the observation array, filtering the attack data before a short TWAP is finalized. Anyone can bootstrap a new feed by adding a WETH-token pair, and no additional token is minted to finance or govern the system. It is categorized as an AMM-based decentralized oracle.
