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>)

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

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