How Do Concrete Vaults Actually Work?
Imagine you’re new to DeFi. You open a platform, deposit your funds into a vault, and suddenly you see new terms like vault shares, eRate, and NAV. Your balance moves over time—but what’s actually happening?
Let’s break it down in a simple, intuitive way.
---
1️⃣ Starting From the User Perspective
You deposit your assets into a vault.
In return, you receive vault shares.
Your wallet now shows:
- A number of shares
- An eRate
- A growing balance over time
At first glance, it’s confusing:
“Why do I have shares instead of my original tokens?”
“What does eRate mean?”
The key idea:
You’re no longer holding tokens directly—you now own a portion of a pooled system.
---
2️⃣ Vault Shares & eRate (Simple Explanation)
Think of a vault like a big jar of assets.
- When you deposit, you get shares of that jar
- Each share represents your ownership
Now, what is eRate?
👉 eRate = value of each share
At the beginning:
- 1 share might equal 1 unit of value
Over time:
- The vault earns yield
- The total value increases
- Each share becomes more valuable
So instead of your share count increasing,
👉 the value of each share grows
---
3️⃣ Understanding NAV (No Jargon)
NAV (Net Asset Value) is simply:
👉 The total value of everything inside the vault
Think of it like this:
- NAV = total pool
- Shares = your slice of that pool
If the vault grows:
- NAV increases
- Your slice stays the same size
- But its value increases
That’s why your balance grows over time.

4️⃣ Why Time Matters
Vaults are not designed for quick in-and-out moves.
Why?
- Strategies need time to generate yield
- There are execution costs (like gas fees)
- Withdrawals are structured for stability
- Markets fluctuate in the short term
A simple analogy:
👉 A vault is like planting a garden
- You plant seeds (deposit)
- You wait (time)
- You harvest later (yield)
If you leave too early,
you don’t get the full result.

5️⃣ Active Management Behind the Scenes
Concrete vaults are not passive.
They don’t just hold your assets—they actively manage them.
Think of it like a chef:
- Capital is deployed into different strategies
- Positions are adjusted over time
- Funds are rebalanced based on market conditions
This is managed DeFi:
👉 Your capital is continuously working, not sitting idle
---
6️⃣ Connecting It All Together
Here’s what’s really happening:
- Your deposit joins a shared pool (NAV)
- You receive ownership (vault shares)
- The system generates yield
- The value of each share (eRate) increases
- Strategies are optimized over time
And most importantly:
👉 Time unlocks compounding
- Yield builds on yield
- Rebalancing captures better opportunities
- Long-term participation improves outcomes
You’re not just earning yield—
you’re benefiting from how it’s managed.

7️⃣ Simple Mental Model
Let’s simplify everything:
- Vault = pooled capital system
- Shares = your ownership
- eRate = value of your shares
- NAV = total vault value
- Time = growth driver
- Management = optimization layer
---
In short:
👉 You deposit assets
👉 You own a piece of the system
👉 The system grows over time
And your value grows with it.
