OOGA is a DEX aggregator that splits its architecture into an on-chain router contract and an off-chain backend where all simulations, routing logic, and transaction building occur. It optimizes trades by simulating how each liquidity source - especially complex ones like v3 AMMs - responds to routing and slippage, aiming to maximize output and minimize price impact. Because backend simulations are off-chain, there's an inherent centralization risk, mitigated by on-chain safeguards like input/output validation and slippage protection. OOGA emphasizes transparency and user awareness, advocating for informed DeFi participation over blind trust.
