# Danogo Multi-Source Oracle Aggregation

### How Danogo mitigate an Oracle attack?

To ensure that loan pricing and collateral risk assessment are based on real-time, decentralized data sources, Danogo leverages two types of oracles:

* Overnight Lending Rate Oracle → Used to calculate fixed-term lending rates.
* Token Price Oracle → Used for collateral valuation.

Danogo’s multi-oracle architecture is a strong innovation in the Cardano DeFi ecosystem. Here’s what makes it stand out:

#### 1. Multi-Source Oracle Aggregation for Redundancy & Security

Danogo supports multiple oracle providers to eliminate single points of failure:\
✅ Current Supported Oracles:

* Orcfax
* DJED
* Liqwid
* Indigo
* Decentralized Exchanges (DEXs) → Minswap, Splash.

🔜 Upcoming Integrations:

* Charli3

By aggregating data from multiple sources, Danogo prevents price manipulation risks that arise from relying on a single oracle.

#### 2. Automatic Oracle Attack Detection & Mitigation

Danogo includes a built-in defense mechanism against oracle manipulation:

* If any single oracle’s price deviates by more than 5% from the average of all oracle feeds, all loan operations related to that price will be suspended.
* This prevents flash loan attacks, price manipulation exploits, and inaccurate liquidations.

#### 3. Continuous Oracle Expansion for Stronger Security

Danogo actively seeks to integrate new oracles to further enhance security and decentralization.

* More oracle providers = higher resilience against data manipulation.
* Integrating DEX price feeds improves real-time accuracy, as DEX prices reflect actual market trades.

Danogo’s commitment to multi-oracle security and decentralized price aggregation makes it the most robust and reliable lending protocol on Cardano.
