## Protocol Coupling

Protocol coupling refers to the structural interdependency between two or more decentralized finance applications where the functionality of one relies directly on the stability of another. This often happens when a lending protocol accepts the native tokens of a decentralized exchange or a synthetic asset protocol as collateral.

If the secondary protocol faces a security exploit or governance failure, the primary protocol becomes immediately insolvent or illiquid. This creates a chain of trust where users are exposed to the risks of every underlying protocol in the stack.

In a complex DeFi ecosystem, these couplings can become recursive, making it nearly impossible to isolate risk. Such structures turn isolated vulnerabilities into systemic threats that can destabilize the entire ecosystem.
