Layered Protocol Dependency

Layered protocol dependency occurs when a financial system relies on a stack of other protocols to function. Each layer introduces its own set of risks, from smart contract bugs to governance failures.

When a protocol is built on top of another, it essentially inherits the risk profile of the entire stack below it. This "money lego" architecture is a hallmark of DeFi but also a major source of systemic risk.

If a base-layer protocol fails, everything built on top of it is potentially compromised. Developers must conduct rigorous due diligence on every layer of the stack and implement fail-safes to isolate their protocol from downstream failures.

This includes creating modular designs that allow for the swapping of underlying components if one becomes compromised. Understanding the depth and nature of these dependencies is essential for building resilient financial infrastructure.
