How Do Concrete Vaults Actually Work?

A Beginner’s View of Vaults: Turning Confusion Into Understanding

You’ve just deposited your funds into a vault. Everything goes through smoothly, and now you see a few new things on your screen: vault shares, eRate, and NAV.

At this point, most users pause and wonder:

What do these actually represent?

It might seem technical at first, but the system behind vaults is actually quite simple. Once you understand a few key ideas, everything starts to click.


Shares and eRate: Understanding Your Ownership

When you deposit into a vault, you are not just adding funds—you are receiving a piece of the system.

Imagine the vault as a large container filled with capital. When you contribute, you receive units that represent your share of that container. These are your vault shares.

Each share reflects your ownership.

Now, instead of giving you more shares over time, the vault increases the value of each share. That’s how growth happens.

This value is represented by eRate.

eRate tells you how much one share is worth. As the vault earns yield and the total value grows, each share becomes more valuable.

So:

  • Your shares = your ownership

  • eRate = the value of that ownership per unit

Your balance grows because each share is worth more—not because you receive additional shares.


NAV: The Total Value Behind Everything

To understand where that value comes from, we look at NAV.

NAV, or Net Asset Value, is simply the total value of all assets held inside the vault.

Think of NAV as the full size of the system.

If the vault holds $800,000, then that is the NAV. If it grows to $900,000, the NAV increases.

Now connect it:

  • NAV = the total pool

  • Shares = your portion of that pool

When NAV increases, your portion becomes more valuable. This is reflected through a higher eRate.

Even though your number of shares stays the same, their value rises as the overall pool grows.


Why Time Is a Key Ingredient

Vaults are designed to work over time—not instantly.

Strategies inside the vault need time to deploy capital, capture opportunities, and generate returns. There are also operational costs like transaction fees and rebalancing that can affect short-term results.

A simple way to think about it is like cooking.

Some meals can be made quickly, but the best ones take time. Ingredients need to blend, flavors need to develop, and the process can’t be rushed.

Vaults work in a similar way.

Time allows:

  • strategies to perform properly

  • returns to accumulate

  • compounding to strengthen growth

Short-term changes don’t always reflect the full potential. The longer you stay, the more the system works in your favor.


Active Management in Action

Vaults are not passive systems where funds just sit still.

They are actively managed.

Your capital is continuously deployed into different strategies, adjusted over time, and optimized based on market conditions.

Think of the vault as a system operator.

It monitors opportunities and decides where capital should go to achieve better results. When conditions change, it adapts.

This includes:

  • allocating funds across strategies

  • rebalancing positions

  • optimizing for both returns and risk

The vault is constantly working behind the scenes to improve performance.


How Everything Works Together

When you combine all these elements, the structure becomes clear.

As time passes:

  • NAV grows through yield generation

  • eRate increases as share value rises

  • your shares maintain your ownership

At the same time:

  • compounding boosts long-term growth

  • rebalancing captures new opportunities

  • active management improves efficiency

Your returns come not just from yield, but from how that yield is managed over time.

The longer you stay in the vault, the more these effects build on each other.


A Simple Way to Remember

Here’s a clean mental model you can use:

  • Vault = a shared capital system

  • Shares = your ownership

  • eRate = value of each share

  • NAV = total value of the vault

  • Time = what drives growth

  • Management = what optimizes outcomes

Once you understand this, vaults become much easier to follow.

What once felt complex is actually a well-structured system designed to grow value steadily—where your role is simply to participate and let time do the work.
