Uniswap: Price Oracle Resilience & Theoretical Soundness

Uniswap is presented as a robust, theoretically sound on-chain price oracle, owing to its constant-product market model, resistance to manipulation, and bounded reserves. Under ideal conditions with no arbitrage and no exchange fees, its market price is said to align with the true market price, though minor divergences can occur in practice. Manipulation is described as costly and inefficient, especially for large-scale price changes. A bZx attack on 02/15/20, which drained the bZx smart contract of funds, is cited as underscoring the need for secure DeFi protocols.
