System-level contracts
System contracts provide functionality that are usually singletons and provide functionality necessary for the rest of the system to work. Note that they generally do not contain the primary protocol logic (except the Price Oracle), but they are essentially prerequisites for the rest of the contracts in the system.
| Contract | Responsibility |
|---|---|
| AddressProvider | Stores the addresses of other system-level contracts. This contract usually serves as an entry point when one wants to map all of the important addresses in the system. |
| AccountFactory | Keeps stock of currently unused Credit Accounts, hands off Credit Accounts to the Credit Manager when a new account is opened, and retrieves the accounts back once they are closed. |
| ACL | Serves as a single source of ground truth regarding admin rights in the system. Other contracts retrieve the configurator address from them for their configuratorOnly functions. |
| ContractsRegister | A registry of pools and Credit Managers recognized by the system. |
| DataCompressor | Outputs rich data on Credit Accounts and Credit Managers in a single call. Designed for off-chain use only. |
| PriceOracle | Provides price data for collateral calculations in Credit Managers. |
| Router | Computes calldata for complex multicalls. |
| BotList | Stores permissions from Credit Accounts to bots. |
| GearStaking | The contract where users stake GEAR in order to vote in designated voting contracts, such as Gauges. |
