The key metrics that gauge the success of Azos:
1) the amount of assets onboarded as collateral
2) the safes opened on azos.finance
3) the amount of ZAI minted
4) the stability module's profitability and health metrics
5) the depth of ZAI liquidity
6) the ZAI redemption rate
7) the number of wallets holding ZAI
8) the number of partners/DAOs that adopt ZAI into their treasury holding/compensation plans

Those Azos success metrics can then be used to help calculate social impact via the ecosystem growth of tokenized/consumed assets. If we are successful, the net inflow of tokenized impact assets will measurably increase.
