Understanding DeFi vaults does not require complex terminology. What it requires is a clear mental model.

Start with the idea of a shared system.

A Concrete vault pools capital from multiple users. When you deposit, you receive vault shares that represent your portion of that pool. This means your position is defined by ownership rather than a fixed balance.

The total value of the pool is called NAV. This includes all assets and positions managed by the vault. As strategies generate yield, NAV increases.

Your shares give you a proportional claim on that NAV.

Now consider eRate. This metric represents the value of each share. When NAV grows, the value backing each share increases, and eRate rises accordingly.

This is how your position grows over time.

The next step is to understand why this system is designed the way it is.

Pooling capital allows for more efficient deployment. Larger pools can access better opportunities, optimize execution, and distribute costs more effectively.

Shares provide a flexible way to track ownership within this system. Instead of constantly recalculating individual balances, the system adjusts value at the share level.

This makes it easier to manage growth and distribute results fairly.

Time is an essential part of this model. Strategies need time to generate yield, and compounding requires repeated cycles of reinvestment. Short-term activity can interrupt these cycles and reduce overall efficiency.

Long-term participation, on the other hand, allows the system to operate as intended.

Active management is what brings the system to life. The vault continuously allocates capital, adjusts positions, and seeks optimal strategies. This ensures that the pool is not static, but constantly evolving.

This combination of pooling, ownership, time, and management creates a powerful framework.

Users benefit not only from the yield generated, but from the structure that supports it. The system is designed to maximize efficiency and capture opportunities over time.

In its simplest form, a Concrete vault can be understood as follows:

It is a pooled capital system where users own shares. The total value of the system is measured by NAV. The value of each share is reflected by eRate. Over time, active management and compounding increase that value.

This mental model removes unnecessary complexity and highlights what truly matters.
