# ConfiguratorLogic

{% hint style="info" %}
This contract tracks **reserve lifecycle events**: initialization of reserves, and upgrades of the proxy contracts for aToken, stable debt token, and variable debt token.
{% endhint %}

### Events 

* **ATokenUpgraded(asset, proxy, implementation)**\
  Emitted when the **aToken contract for a reserve is upgraded** to a new implementation.
  * `asset`: The underlying asset of the reserve.
  * `proxy`: The proxy contract address of the aToken.
  * `implementation`: The new implementation contract address.

***

* **ReserveInitialized(asset, aToken, stableDebtToken, variableDebtToken, interestRateStrategyAddress)**\
  Emitted when a **new reserve is initialized** in the protocol.
  * `asset`: The underlying asset of the reserve.
  * `aToken`: The address of the aToken contract representing deposits.
  * `stableDebtToken`: The address of the stable debt token contract.
  * `variableDebtToken`: The address of the variable debt token contract.
  * `interestRateStrategyAddress`: The strategy contract managing interest rate models for the reserve.

***

* **StableDebtTokenUpgraded(asset, proxy, implementation)**\
  Emitted when the **stable debt token contract** for a reserve is upgraded.
  * `asset`: The underlying asset.
  * `proxy`: The proxy contract address of the stable debt token.
  * `implementation`: The new implementation contract address.

***

* **VariableDebtTokenUpgraded(asset, proxy, implementation)**\
  Emitted when the **variable debt token contract** for a reserve is upgraded.
  * `asset`: The underlying asset.
  * `proxy`: The proxy contract address of the variable debt token.
  * `implementation`: The new implementation contract address.
