Connectors are standard proxy logics contract that let DeFi Smart Account (DSA) interact with various smart contracts, and make the important actions accessible like cross protocol interoperability.

DSAs are powerful because they can easily be extended with connectors. Every new connector that is added is immediately usable by any developer building on top of DSAs.
