PoolDataProvider

This contract is a read-only data provider. It gives access to all the parameters and user positions without modifying state (view/pure functions).

🔹 Constructor

• constructor(address addressesProvider) Initializes the contract with a reference to the Aave PoolAddressesProvider.

---

🔹 Core getters

• ADDRESSES_PROVIDER() → address Returns the address of the PoolAddressesProvider linked to this instance.

---

🔹 Token and reserve information

• getATokenTotalSupply(address asset) → uint256 Returns the total supply of the aToken for a given underlying asset.

• getAllATokens() → TokenData[] Returns a list of all aTokens (symbol + address) registered in the pool.

• getAllReservesTokens() → TokenData[] Returns a list of all underlying reserve tokens (symbol + address) supported in the pool.

---

🔹 Risk management & configuration

• getDebtCeiling(address asset) → uint256 Returns the debt ceiling configured for a given asset.

• getDebtCeilingDecimals() → uint256 Returns the number of decimals used for debt ceiling calculations.

• getFlashLoanEnabled(address asset) → bool Indicates whether flash loans are enabled for a given asset.

• getInterestRateStrategyAddress(address asset) → address Returns the address of the interest rate strategy contract used for a given asset.

• getLiquidationProtocolFee(address asset) → uint256 Returns the protocol fee (in bps) charged during liquidation for a given asset.

• getPaused(address asset) → bool Returns whether the reserve is paused (no deposits/borrows allowed).

• getReserveCaps(address asset) → (borrowCap, supplyCap) Returns the configured borrowing and supply caps for the reserve.

• getReserveConfigurationData(address asset) Returns risk configuration parameters for the reserve, including:

  • decimals, LTV, liquidation threshold, liquidation bonus, reserve factor

  • flags for collateral usage, borrowing enabled, stable rate enabled, active/frozen status.

• getReserveEModeCategory(address asset) → uint256 Returns the eMode (efficiency mode) category assigned to the asset.

• getReserveTokensAddresses(address asset) → (aToken, stableDebtToken, variableDebtToken) Returns the addresses of the tokens associated with a reserve.

• getSiloedBorrowing(address asset) → bool Indicates if the asset enforces siloed borrowing (only one type of asset can be borrowed when this one is used).

• getUnbackedMintCap(address asset) → uint256 Returns the cap for unbacked aToken minting for the given reserve.

---

🔹 Reserve state

• getReserveData(address asset) Returns detailed reserve metrics:

  • unbacked liquidity, accrued treasury, total aToken supply

  • total stable/variable debt, liquidity & borrowing rates

  • average stable borrow rate, liquidity/variable indexes

  • last update timestamp.

• getTotalDebt(address asset) → uint256 Returns the total debt (stable + variable) for a reserve.

---

🔹 User-specific data

• getUserReserveData(address asset, address user) Returns information about a user’s position in a given reserve:

  • aToken balance, stable and variable debts

  • principal stable debt, scaled variable debt

  • stable borrow rate, liquidity rate

  • last stable rate update, collateral usage status.
