Whitelisted tokens on the 3A platform could affect the protocol and its EURO3 stablecoin at its core, so it is crucial to build a robust and systematic risk model.

This section outlines the 3A Risk methodology, the main categories, and the factors that compose them.

3A DAO relies on these underlying factors to assess a protocol’s creditworthiness and decides if a token can get whitelisted as collateral.
