How Do Concrete Vaults Actually Work?

How Do Concrete Vaults Actually Work?

gm. Let’s say you just deposited into a vault on Concrete.

You put your assets in… and suddenly you have “vault shares.” You notice numbers like eRate and NAV changing over time. Your balance looks stable, but somehow it’s also growing.

Naturally, the question hits:

What’s actually going on under the hood?

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

Start With the User Perspective

From your point of view, it feels simple:

• You deposit funds into a vault
• You receive vault shares
• Over time, your position increases in value

But then you see terms like:

• eRate
• NAV
• Share price

And it starts to feel like you’ve stepped into a finance class you didn’t sign up for.

Here’s the truth: It’s not complicated. It’s just unfamiliar.

Vault Shares & eRate (Without the Headache)

Think of a Concrete vault like a large jar filled with assets.

When you deposit, you don’t just “add money.” You receive vault shares, which represent your ownership of that jar.

If the vault is the jar, then:

• Shares = your slice of the jar
• The more shares you hold, the bigger your portion

Now enter eRate.

eRate is simply the value of each share.

So if:

• The vault performs well
• The strategies generate yield

Then the total value inside the jar increases.

But your number of shares stays the same.

Instead, each share becomes more valuable.

That’s why your balance grows over time, even though you’re not getting more shares.

NAV (Net Asset Value), Made Simple

NAV sounds intimidating, but it’s actually very straightforward.

NAV = the total value of everything inside the vault

That includes:

• Deposited assets
• Earned yield
• Active positions across strategies

So:

• NAV goes up when the vault earns yield
• NAV reflects the overall health of the vault

Here’s the clean mental model:

• NAV = the full pie
• Shares = your slice of the pie

When the pie gets bigger, your slice is worth more, even if its size (in shares) doesn’t change.

Why Time Matters More Than You Think

This is where most people get it wrong.

Vaults are not built for quick in-and-out moves.

They are designed for time-based growth.

Why?

Because:

• Strategies need time to generate yield
• Positions need time to mature
• Rebalancing takes place over time
• There are real costs (gas, execution, adjustments)

Think of it like planting a garden.

You don’t plant seeds today and harvest tomorrow. You give it time to grow, adjust, and compound.

Short-term, you might see small fluctuations. Long-term, the system starts to work in your favor.

Time is what unlocks compounding.

Active Management (Not Just Sitting Idle)

A key thing to understand:

Concrete vaults are not passive pools.

Your capital isn’t just sitting there.

It’s being actively managed.

That means:

• Funds are deployed across different strategies
• Positions are adjusted based on market conditions
• Capital is rebalanced to capture better opportunities

Think of the vault like a skilled operator in the background.

Or better yet, a chef in a kitchen:

You provide the ingredients. The system decides how to combine them for the best result.

This is what makes it managed DeFi, not just static yield.

How This All Connects to Outcomes

Now let’s connect the dots.

When you deposit into Concrete vaults:

• Your capital is pooled with others
• You receive shares representing your ownership
• The vault actively deploys that capital onchain
• Strategies generate yield over time
• That yield increases the NAV
• Which increases the value of each share (eRate)

And because everything compounds:

• Gains build on previous gains
• Rebalancing improves efficiency
• Longer participation generally leads to better outcomes

You’re not just earning yield.

You’re benefiting from how that yield is generated and optimized.

A Simple Mental Model to Take Away

If you remember nothing else, remember this:

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

That’s it.

No complexity. No mystery.

Just a system designed to take your capital, put it to work, and grow it over time in a structured, managed way.
