Scene 1 · One button
“Simple. Deposit and earn.”
Deposit
10,000 USDC
The protagonist has 10,000 USDC and one button. They expect a straight line: USDC → yield.“To the user, it looks like one transaction.”

“Wait… there is another layer?”
We pass through the vault wall. Inside is a machine: the , which decides where the vault’s capital goes.

Strategy A · Lending
The allocator splits capital across several . Select a node to see what kind of route it represents. These four are illustrative categories. The exact allocation depends on the specific vault and its strategy configuration, and no allocation weights are implied.

One branch enters , where it finds not one market but several curated vaults. Concrete’s Morpho USD vault is described as automating USDC deposits across multiple Morpho vaults, operated by curators including Gauntlet, MEV Capital and RE7 Labs, and among them programmatically. That makes it a vault of vaults.

A different route: Concrete × Morph vaults deploy capital through partner protocols inside the Morph ecosystem, with BulbaSwap and Quokka Lend named as initial allocations. Note that these are separate vaults on the Morph network. They are a second example of the same architecture, not another branch of the protagonist’s single deposit.
Scene 7 · The protagonist is confused
“So my USDC isn’t just sitting in one place?”
“Correct. But you don’t need to manually manage every position.”

Illustrative motion only, not actual allocation weights
The allocator watches conditions such as rates, and limits, and shifts capital between approved routes. The user’s ctUSDC balance does not need to change for the mix underneath it to change.

Market risk
“If Concrete handles all of that, does that mean there is no risk?”
The screen answers with six words that do not go away.“Abstraction doesn’t remove risk. It moves the complexity somewhere else.”

CUT TO → CONCRETE VAULT
Doing it by hand means ten apps, ten dashboards, and rates, strategies and liquidity that change while you look. The person is exhausted. Then we cut back to one vault.“The purpose of the allocation layer is not to make DeFi risk disappear. It is to make complex capital allocation programmable.”
Scene 11 · The bigger picture
Zoom out. Lending, liquidity, restaking, RWA, BTC and stablecoin markets are all categories that Concrete vaults have been documented to touch. This shows connection, not size or share.“As DeFi becomes more fragmented, the infrastructure connecting these markets becomes increasingly important.”
Final scene
10,000 USDC
“I thought I was depositing into a vault.”
“You were.”
“Just not the only one.”

Definitions
VaultA smart contract that accepts deposits, issues shares and deploys assets into supported strategies.
AllocatorThe automated role that decides how a vault’s capital is distributed across approved strategies and when to rebalance.
StrategyA specific route for deploying capital, such as lending, liquidity provision or a hedged position. Risks depend on the route.
ctAssetA tokenized vault share (e.g. ctUSDC) representing a proportional claim on the vault’s assets.
MorphoA lending protocol with isolated markets and curated Morpho Vaults run by independent curators.
LiquidityHow readily a position can be exited without large cost or delay. It can change quickly in stress.
RebalancingMoving capital between strategies to follow the vault’s rules as rates, limits or conditions change.
MorphA Layer-2 network whose Concrete vaults allocate across ecosystem partners such as BulbaSwap and Quokka Lend.
