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.
