# Layer 2: DeFi Enablement & Liquidity Abstraction Layer

{% hint style="info" %}
**What it is:** A compatibility layer that allows tokenised institutional instruments to interface with on-chain financial systems when appropriate.
{% endhint %}

### Primary function

> * Convert tokenised instruments into **composable on-chain primitives** via standardised mechanisms.

### How it works (conceptually)

> * Built on top of Layer 1.
> * Uses **vault and wrapper mechanisms** to represent instruments in formats that can interact with on-chain financial infrastructure.

### What it can enable

> * **Liquidity routing:** technical pathways for assets to interact with liquidity environments.
> * **Yield abstraction:** packaging/standardising yield-bearing instruments into on-chain primitives.
> * **Collateralisation:** making instruments usable as collateral within institutional-grade on-chain contexts.

### Control model

> * **Optional + issuer-controlled:** activation is decided by asset originators/managers.
> * Used only when it aligns with product design, governance, and risk posture.

{% hint style="warning" %}

## What it does <mark style="color:red;">**not**</mark> do

* Does not originate assets or “create investment exposure.
* Does not guarantee liquidity.
* Does not assume DeFi participation; it simply provides the **technical abstraction** when needed.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://bzl.gitbook.io/bzl-docs/architecture/core-layer/layer-2-defi-enablement-and-liquidity-abstraction-layer.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
