A DeFi aggregator is a platform that consolidates various decentralized finance protocols to provide users with the best yields, lowest fees, and optimal trading opportunities across multiple decentralized exchanges (DEXs). By leveraging smart contracts, these aggregators automatically route transactions through the most efficient pathways, enhancing liquidity and minimizing slippage. Users benefit from streamlined access to diverse DeFi services, including lending, borrowing, and yield farming, all within a single interface. This fosters a more user-friendly experience in the DeFi ecosystem.
