Data in Depth

##Data Source The data used in the DeFi Survival Analysis Toolkit is from The Graph.

In the current state of the app, the utilized data is from the DeFi lending protocol Aave. Aave pushes its own data to The Graph, and each network Aave is deployed on has its own subgraph. These subgraphs are structured identically, with respect to the transaction-level data.

The data currently available for use within the toolkit comes from the Aave-maintained subgraphs, specifically the following 7 markets:

Ethereum (V2), Polygon (V3), Avalanche (V3), Optimism (V3), Harmony (V3), Fantom (V3), Arbitrum (V3).

We have collected all of the transaction data from nine subgraphs maintained by Aave, which include the data from the following Aave markets: Ethereum, Polygon, Avalanche, Optimism, Harmony, Fantom and Arbitrum. There are currently two versions of Aave in deployment, referred to simply as V2 and V3. The Ethereum markets only operate on AaveV2, the Polygon and Avalanche markets have both AaveV2 and AaveV3 versions in deployment, and the rest are exclusive to AaveV3.
