You deposit into a vault.
You receive shares.
Your balance starts growing over time.
Simple on the surface.
But if you’ve ever looked at numbers like eRate or NAV, you’ve probably asked:
“What do these actually mean?”
Let’s break it down — in the simplest way possible.
Imagine this:
You deposit USDT into a Concrete vault.
Immediately, you receive something called vault shares.
Your wallet now shows a balance — not just in tokens, but in shares.
Over time, you notice something interesting:
Your share value increases.
You didn’t move funds.
You didn’t farm manually.
You didn’t rebalance anything.
Yet your position is growing.
So what’s happening under the hood?
Let’s start with the basics.
Think of the vault like a big pool of capital.
When you deposit, you don’t just “put money in.”
You receive shares that represent your slice of that pool.
👉 If the vault is a pizza:
The whole pizza = total capital
Your shares = your slices
Now comes the key metric: eRate.
eRate tells you:
How much each share is worth
At the beginning, 1 share might equal $1.
But as the vault generates yield, that changes.
1 share → $1.02
then → $1.05
then → $1.10
You still own the same number of shares.
But each share becomes more valuable over time.
That’s how your balance grows.
Now let’s talk about NAV (Net Asset Value).
In simple terms:
NAV = total value of everything inside the vault
It includes:
deposited capital
earned yield
active positions
NAV = the full pool
Shares = your portion
eRate = value per share
👉 When NAV increases → share value increases → your balance grows.
You don’t need to do anything manually.
The system updates it for you.
This is where most people misunderstand vaults.
Vaults are not designed for short-term flipping.
They are built for time-based growth.
Because yield generation takes time:
strategies need time to perform
rewards need time to accumulate
compounding needs time to accelerate
There are also real-world frictions:
gas costs
execution timing
rebalancing intervals
You don’t plant seeds and expect results overnight.
Day 1 → nothing
Week 1 → small growth
Month 1 → visible results
Long-term → exponential growth
Vaults work the same way.
Time is what unlocks compounding.
Short-term noise exists.
Long-term growth is where the real value is.
A common misconception:
Vaults are “set and forget.”
That’s only half true.
Behind the scenes, Concrete vaults are actively managing capital.
Capital is:
deployed across different strategies
rebalanced as conditions change
adjusted based on risk and yield
Think of the vault like a chef in a kitchen.
You bring the ingredients (your capital).
The chef:
chooses the recipe (strategy)
adjusts seasoning (risk/reward)
switches dishes when needed (rebalancing)
You don’t cook.
But your meal keeps improving.
Now connect everything:
Automated compounding → reinvests rewards continuously
Rebalancing → captures better opportunities
Onchain capital deployment → keeps funds active
Managed DeFi → reduces user effort
You’re not just earning yield.
You’re benefiting from:
how that yield is managed over time
And that makes a big difference.
Because in DeFi:
timing matters
execution matters
consistency matters
Vaults optimize all three.
Let’s bring it all together:
Vault = pooled capital system
Shares = your ownership
eRate = value per share
NAV = total vault value
Time = growth driver
Management = optimization layer
Concrete vaults take complex DeFi strategies and turn them into something simple:
You deposit once.
The system does the rest.
No constant monitoring.
No manual compounding.
No chasing every new strategy.
Just structured, automated onchain capital deployment.
