CartesiDAppFactory

The CartesiDAppFactory contract is a tool for reliably deploying new instances of the CartesiDApp contract with or without a specified salt value for address derivation.

Additionally, it provides a function to calculate the address of a potential new CartesiDApp contract based on input parameters.

This contract ensures efficient and secure deployment of CartesiDApp contracts within the Cartesi Rollups framework.

newApplication()

function newApplication( IConsensus consensus, IInputBox inputBox, IPortal[] memory portals, address appOwner, bytes32 templateHash ) external returns (Application)

Deploys a new Application contract without specifying a salt value for address derivation.

Emits an ApplicationCreated event upon successful deployment.

Parameters

Name	Type	Description
consensus	IConsensus	Instance of the consensus interface
inputBox	IInputBox	Instance of the input box interface
portals	IPortal[]	Array of portal instances
appOwner	address	Address of the owner of the application
templateHash	bytes32	Hash of the template for the application

newApplication()(with salt)

function newApplication(IConsensus consensus, IInputBox inputBox, IPortal[] memory portals, address appOwner, bytes32 templateHash, bytes32 salt) external returns (Application)

Deploys a new Application contract with a specified salt value for address derivation.

Emits an ApplicationCreated event upon successful deployment.

Parameters

Name	Type	Description
consensus	IConsensus	Instance of the consensus interface
inputBox	IInputBox	Instance of the input box interface
portals	IPortal[]	Array of portal instances
appOwner	address	Address of the owner of the application
templateHash	bytes32	Hash of the template for the application
salt	bytes32	Salt value for address derivation

calculateApplicationAddress()

function calculateApplicationAddress(IConsensus consensus,IInputBox inputBox,IPortal[] memory portals,address appOwner,bytes32 templateHash,bytes32 salt ) external view returns (address)

Calculates the address of a potential new Application contract based on input parameters.

Parameters

Name	Type	Description
consensus	IConsensus	Instance of the consensus interface
inputBox	IInputBox	Instance of the input box interface
portals	IPortal[]	Array of portal instances
appOwner	address	Address of the owner of the application
templateHash	bytes32	Hash of the template for the application
salt	bytes32	Salt value for address derivation

Returns

Type	Description
address	Address of the potential new Application contract
