Aave v2 calculation of total number of tokens that can be borrowed on chain
- Borrow rate
- Aave v2 Aave
Is it possible to calculate total number of tokens that can be borrowed on chain? (For Aave v2)
You can use protocol data provider for
getReserveData and compute the available liquidity (total supplied - total debt). This is the max amount that can be drawn from the Aave pool.
Max amount a user can borrow depends on the collateral supplied. The limit is HF should not be <1 afterwards. You can use
getUserAccountData method in pool to get user's total collateral and existing debt balance across all reserves https://docs.aave.com/developers/core-contracts/pool#getuserconfiguration
and compute the max amount that can be drawn without dipping HF below 1.
