# Overview

**Arenas** brings real-world financing on-chain by connecting two existing systems with a single, thin piece of glue.

Arenas deploys **one contract of its own — the Credit Delegation Module (CDM)**. Everything else it uses is external and already deployed:

| Piece       | What it is                                                                                           | Whose contracts                       |
| ----------- | ---------------------------------------------------------------------------------------------------- | ------------------------------------- |
| **Atomica** | The credit engine — approval-gated, undercollateralized financing markets.                           | **Atomica** contracts (Base)          |
| **Aave**    | An optional liquidity source, used via standard credit delegation for boosted yield.                 | **Aave v3** contracts (Base)          |
| **CDM**     | Arenas’ own **Credit Delegation Module** — routes Aave borrowing power into Atomica financing pools. | **Arenas** (the only Arenas contract) |

Arenas is **not** an Aave fork and does not run its own liquidity protocol. It uses Aave v3 and Atomica as they are, and adds the CDM to connect them.

### How it fits together

```

* **Borrowers** get approval-gated credit from [**Atomica**](/atomica/key-concepts.md) markets — no on-chain collateral.
* **Suppliers / LPs** earn Atomica yield, and can amplify it by delegating Aave credit through the **CDM** (the [Aave Market](/arenas/aave-market.md) strategy).

### Where to start

* Understand the credit engine → [**Atomica → Key Concepts**](/atomica/key-concepts.md).
* The Arenas piece itself → [**Credit Delegation Module**](/arenas/credit-delegation.md).
* Earn boosted yield → [**Aave Market**](/arenas/aave-market.md).
* Build an integration → [**Build with Arenas**](/build-with-arenas/build.md).

### Networks

Arenas operates on **Base** (chain 8453), alongside the Atomica deployments on Base, Arbitrum One and Boba.
