Protocol Layering Risk

Protocol layering risk arises when financial applications are built in layers, with each layer depending on the security and integrity of the one beneath it. In DeFi, this is common: a yield aggregator might deposit user funds into a lending protocol, which in turn uses a decentralized exchange to manage collateral.

If the base layer (the exchange) suffers a security breach or an economic failure, all layers above it are impacted. This creates a complex web of dependencies that is difficult to audit and monitor.

Investors often underestimate this risk, focusing only on the yield offered by the top layer without considering the cumulative risk of the entire stack. Proper risk management requires a bottom-up analysis of every protocol involved in the chain of dependencies.
