How Arenas uses Atomica

Arenas does not have its own credit or liquidity contracts. It uses Atomica (Base) as the credit engine and Aave v3 (Base) as an optional liquidity source, and adds a single contract — the Credit Delegation Module (CDM) — to connect them.

Who owns what

System	Provides	Contracts
Atomica	Financing markets, pools, obligations, the request → approve → draw-down → repay lifecycle.	Atomica’s own (Base)
Aave v3	Overcollateralized supply/borrow and credit delegation.	Aave’s own (Base)
Arenas	The CDM, which delegates Aave borrowing power into Atomica pools.	One contract — the CDM

What Atomica handles

Every Arenas financing market is an Atomica market. Atomica enforces:

• The shared request → approve → draw down → repay lifecycle.

• Fee and permission limits.

• One standardized engine for liquidity, disbursement, repayment and accounting.

See Atomica → Key Concepts and Atomica Protocol.

What Arenas adds

Arenas’ contribution is the CDM and the product around it:

• Boosted yield — the CDM lets a supplier keep collateral on Aave, delegate its borrowing power, and route the borrowed liquidity into Atomica pools to earn the spread. See Credit Delegation Module and the Aave Market strategy.

• Distribution — the app (app.arenas.fi), lending experience (arenas.fi), and the API/SDK/CLI in Build with Arenas.

In short: Atomica is the credit engine, Aave is optional liquidity, and Arenas is the CDM that connects them plus the product experience on top.
