How Do Concrete Vaults Actually Work?

You open the app, deposit your funds into a vault, and suddenly you’re holding something called shares. Then you notice numbers like eRate and NAV slowly moving.

At first glance, it feels simple. Deposit in, balance goes up.
But under the surface, there’s a lot more happening.

Let’s break it down in a way that actually makes sense.

Starting From the User Experience

Imagine this.

You deposit $1,000 into a Concrete vault.
Instead of seeing “$1,000 sitting there,” you receive vault shares.

Your wallet now shows something like:

A few days later, your share count stays the same.
But your balance increases.

Naturally, the question comes up.
If I didn’t get more shares, where did the growth come from?

Vault Shares and eRate, Made Simple

Think of a vault like a big jar filled with money from many users.

When you deposit, you’re not just adding money.
You’re buying a slice of that jar.

At the beginning, 1 share might equal $1.
That’s your starting eRate.

As the vault generates yield, the total value grows.
But your number of shares doesn’t change.

Instead, the value per share increases.

So if eRate moves from 1.00 to 1.05, your shares are now worth more.
That’s how your balance grows without changing your share count.

Understanding NAV Without the Noise

NAV stands for Net Asset Value, but don’t let that intimidate you.

Just think of it as:

The total value of everything inside the vault.

That includes:

So:

When NAV increases, every slice becomes more valuable.
That’s why your position grows over time.

Why Time Actually Matters

Vaults aren’t designed for quick in-and-out moves.

They behave more like a growing system.

Imagine planting seeds.
You don’t expect a harvest the next day.

The same applies here.

If you enter and exit too quickly, you might miss the upside entirely.

But if you stay longer:

Time isn’t just a factor.
It’s the main driver of results.

Not Just Sitting There, Active Management

Concrete vaults aren’t passive storage.

They’re actively managed systems.

Think of it like having a skilled operator behind the scenes.

Capital inside the vault is:

Instead of you manually chasing yields, the vault does it for you.

This is what makes it managed DeFi rather than just holding assets.

How It All Comes Together

Now connect the pieces.

Over time:

At the same time, the vault is constantly adjusting where capital goes.
That means you’re not just earning yield.

You’re benefiting from how that yield is managed.

A Simple Mental Model

If you remember nothing else, keep this:

That’s it.

Concrete vaults turn complex onchain capital deployment into something simple for the user.

Deposit once.
Let the system work.
Give it time.
