# Squid Aggregator The Squid Aggregator is the routing layer that connects users to the best cross-chain execution paths across the entire crypto ecosystem. Instead of relying on a single bridge or liquidity source, Squid indexes multiple interoperability protocols, liquidity networks, and settlement systems. When a user submits an action, Squid determines the best route across these services to execute it quickly, securely, and efficiently. Think of it as the connectivity layer of crypto. Just like internet routers decide how packets move across networks, the Squid Aggregator decides how value moves across chains. This architecture allows Squid to support swaps, contract calls, and complex cross-chain actions while abstracting away the complexity of fragmented infrastructure. ## Widget --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
