Basics

The easiest way to register a new app is to use the registerApp method. It registers a new app and mints the NFT to the creator.

For example, if you want to register a new app, you can call:

registerApp(<NAME>, <PARENT_CONTRACT>, <APP_CONTRACTS>, <APP_LIMITS>, <DEV_EOAS>)

App Limits

Every app has limits that define its rate and gas usage.

The following limits will be used to define the app's properties.

Name	Number
RATE_LIMIT_PERIOD	1 minute
RATE_LIMIT_THRESHOLD	10
GAS_LIMIT_PERIOD	30 days
GAS_LIMIT_THRESHOLD	0.01 ether

Using the following call method, you can quickly check an app's limits:

getContractLimits(<CONTRACT_ADDRESS>)

Sponsored Contracts

Apps can sponsor other contracts, allowing them to operate under their limits.

For example, to check whether a contract is sponsored by an app:

isSponsored(<APP_ADDRESS>, <CONTRACT_ADDRESS>)

State Functions

Privileged roles can call the following functions.

function registerApp(string calldata appName, address parentContract, address[] calldata appContracts, uint256[4] calldata appLimits, address[] calldata devEOAs) external;

function updateMetadata(string calldata appName, address parentContract, address[] calldata appContracts, uint256[4] calldata appLimits, address[] calldata devEOAs) external;

function setSponsoredContracts(address _app, address[] calldata _contracts, bool[] calldata _flags) external;

function enableDSA(address app) external;

function overrideChildToParentContract(address child, address parent) external;

function updateSystemContracts(address[] calldata newSystemContracts) external;

function setDeployerEOA(address wallet, address deployer) external;
