According to CoinMeta, Uniswap Labs has launched Aggregator Hooks, which integrates external DEX pricing and supports the routing systems of Ethereum mainnet, Base, and Robinhood Chain. This feature wraps external sources as V4 Hooks, allowing the routing engine to compare prices and construct trading routes that include Uniswap with external venues, with settlements occurring within a single transaction. Exchanges routed through Aggregator Hooks can generate protocol fees that support the destruction of UNI tokens. Developers can integrate new routes through Uniswap API, and regular users will see external liquidity incorporated into eligible exchanges.
