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:
- 1,000 shares
- eRate at 1.00
- NAV reflecting total vault value
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.
- Vault shares represent your slice
- eRate represents how much each slice is worth
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:
- user deposits
- accumulated yield
- active positions
So:
- NAV is the full jar
- Shares are your slice of that jar
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.
- Strategies need time to generate returns
- Transactions cost gas and fees
- Positions may take time to mature
- Markets move in cycles, not straight lines
If you enter and exit too quickly, you might miss the upside entirely.
But if you stay longer:
- yield compounds
- strategies play out fully
- volatility smooths out
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:
- deployed across different opportunities
- adjusted when conditions change
- rebalanced to maintain efficiency
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.
- Your deposit becomes shares
- Shares represent ownership
- NAV reflects total value
- eRate tracks value per share
Over time:
- strategies generate yield
- that yield increases NAV
- higher NAV increases eRate
- higher eRate increases your balance
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:
- Vault is a pooled capital system
- Shares are your ownership
- eRate is the value of your ownership
- NAV is the total pool value
- Time drives growth
- Management improves outcomes
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.
