How Do Concrete Vaults Actually Work?

--

You deposit into a vault.
You receive shares.
Your balance grows over time.

Simple on the surface.

But what’s actually happening under the hood?

If you’re new to DeFi or even new to Concrete vaults terms like eRate and NAV can feel confusing.

This article breaks it down in the simplest way possible.

Starting From the User Perspective

Let’s begin with what you actually see.

You deposit funds into a vault.
In return, you receive vault shares.
Over time, your balance increases.

You might also notice metrics like:

eRate
NAV

At first glance, it’s not obvious what these mean.

But once you understand the basics, everything becomes much clearer.

Vault Shares & eRate (Simple Explanation)

Think of a vault like a pool of capital.

When you deposit, you’re not just putting money in you’re getting a piece of that pool.

That piece is represented by your vault shares.

Simple analogy:

Imagine a jar.

The jar = the vault
The total money inside = all deposits
Your shares = your slice of the jar

Now, what is eRate?

eRate is simply the value of each share.

As the vault generates yield, the total value increases.

But instead of giving you more shares, the system increases the value of each share.

So:

Shares stay the same
Value per share (eRate) increases
That’s how your balance grows.

What Is NAV?

NAV stands for Net Asset Value.

In simple terms:

NAV = the total value of everything inside the vault.

It includes:
all deposited funds
all accumulated yield
Using the same analogy:
NAV = everything inside the jar
Shares = your portion of the jar
As NAV increases, your shares become more valuable.

That’s the key relationship.

Why Time Matters

Vaults are not designed for quick in-and-out moves.
They are built for time-based growth.

Here’s why:

Strategies need time to generate yield
There are execution costs (like gas and fees)
Rebalancing happens over time
Markets move in cycles

Think of it like a garden.

You don’t plant seeds and harvest the next day.
You give it time to grow.
In the same way, automated compounding in vaults works best over longer periods.
Short-term fluctuations can happen.
But long-term participation allows the system to work in your favor.

Vaults Are Actively Managed

A common misconception is that vaults are passive.
They’re not.
Concrete vaults are part of managed DeFi infrastructure.

Behind the scenes:

Capital is deployed across different strategies
Positions are adjusted over time
Opportunities are rebalanced
Risk is managed

Think of it like a system operator or a chef managing ingredients.

The vault isn’t just holding funds it’s actively working them.

How This Creates Better Outcomes

When everything works together, the results improve over time.

Compounding increases value gradually
Rebalancing captures better opportunities
Automation reduces missed opportunities
Onchain capital deployment keeps funds active

The key point:
You’re not just earning yield.
You’re benefiting from how that yield is managed.

A Simple Mental Model

Let’s simplify everything:

Vault = pooled capital system
Shares = your ownership
eRate = value of your shares
NAV = total vault value
Time = growth driver
Management = optimization layer

Once you understand this, the system becomes intuitive.

Concrete vaults are not just tools for earning.

They are systems designed for efficient, long-term capital growth.
