How Do Concrete Vaults Actually Work?

“I Deposited… But What’s Actually Happening?”

Let’s be real.

Most people’s first experience with DeFi vaults looks like this:

You deposit funds. You receive some “shares.” You see numbers like eRate and NAV. And over time… your balance goes up.

Sounds great.

But also a little confusing.

Because naturally, you start wondering:

“What is actually going on behind the scenes?”

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

First, Think of a Vault Like a Shared Pool

Imagine a big pool where everyone puts their money together.

That’s basically what a vault is.

When you deposit, your money joins that pool.

But instead of tracking everyone’s exact deposit separately, the system does something smarter:

👉 it gives you vault shares

So What Are Vault Shares?

The easiest way to understand this is with a simple analogy.

Think of the vault like a cake 🎂

• The whole cake = the vault
• Each slice = a share
• Your deposit = how many slices you get

So instead of saying “this is your money,” the vault says:

👉 “this is your percentage of the total pool”

That percentage is your ownership.

Okay… Then What Is eRate?

Now comes the interesting part.

Your number of shares doesn’t usually change much.

What changes is their value.

That’s what eRate represents.

👉 eRate = how much each share is worth

At the start:

• 1 share = 1 unit of value

Over time:

• 1 share = more than 1

Why?

Because the vault is generating yield in the background.

So instead of giving you more shares, the system simply makes each share more valuable.

Think of it like this:

You don’t get more slices of cake.

Your slices just slowly become… bigger.

What About NAV?

Now zoom out for a second.

If your shares are your slice… then what’s the total cake worth?

That’s NAV (Net Asset Value).

👉 NAV = total value of everything inside the vault

It includes:

• all deposits
• all earnings
• all active strategies

So when NAV increases:

👉 the whole pool grows 👉 your share of that pool becomes more valuable

Simple as that.

Why Time Actually Matters (A Lot)

This is where many people get it wrong.

Vaults are not built for quick flips.

They’re built for time.

Here’s why:

• Strategies need time to generate yield
• Moving capital has costs (gas, fees, execution)
• Compounding only works if you let it run

Think of it like planting something 🌱

You don’t plant today and harvest tomorrow.

You give it time to grow.

If you leave too early, you miss the real value.

Vaults work the same way.

👉 The longer you stay, the more the system works in your favor.

One Important Thing: Vaults Aren’t Passive

A lot of people assume vaults just “hold funds.”

That’s not true.

Behind the scenes, they’re doing a lot.

The vault is constantly:

• deploying capital into different strategies
• rebalancing positions
• adjusting to market conditions
• optimizing for better returns

Simple way to think about it:

The vault is like a skilled operator working for you.

You don’t see every move.

But it’s constantly making decisions to improve outcomes.

That’s what managed DeFi really means.

Putting It All Together

Let’s connect everything in a simple way:

• You deposit → you get shares
• Shares = your ownership
• eRate goes up → your shares become more valuable
• NAV grows → the whole vault grows
• The system actively manages capital
• Yield gets compounded automatically

And over time?

👉 your position grows without you doing anything extra

The Simple Mental Model

If you remember nothing else, remember this:

• Vault = shared pool
• Shares = your slice
• eRate = value of your slice
• NAV = size of the whole pool
• Time = what makes it grow
• Management = what makes it efficient

That’s it.

That’s how Concrete vaults actually work.

Final Thought

Vaults aren’t just about earning yield.

They’re about not having to manage everything yourself.

Instead of constantly moving funds, claiming rewards, and chasing opportunities…

you plug into a system that does it for you.

And over time, that makes a big difference.
