IL2ContractDeployer

Author: Matter Labs

System smart contract that is responsible for deploying other smart contracts on a ZK chain.

Functions

Returns what types of bytecode are allowed to be deployed on this chain

function allowedBytecodeTypesToDeploy()
  external
  view
  returns (AllowedBytecodeTypes mode);

This method is to be used only during an upgrade to set bytecodes on specific addresses.

function forceDeployOnAddresses(ForceDeployment[] calldata _deployParams)
  external;

Deploys a contract with similar address derivation rules to the EVM's CREATE2 opcode.

function create2(bytes32 _salt, bytes32 _bytecodeHash, bytes calldata _input)
  external;

Parameters

Name	Type	Description
`_salt`	`bytes32`	The create2 salt.
`_bytecodeHash`	`bytes32`	The correctly formatted hash of the bytecode.
`_input`	`bytes`	The constructor calldata.

Changes what types of bytecodes are allowed to be deployed on the chain.

function setAllowedBytecodeTypesToDeploy(
  AllowedBytecodeTypes newAllowedBytecodeTypes
) external;

Parameters

Name	Type	Description
`newAllowedBytecodeTypes`	`AllowedBytecodeTypes`	The new allowed bytecode types mode.

A struct that describes a forced deployment on an address.

struct ForceDeployment {
  bytes32 bytecodeHash;
  address newAddress;
  bool callConstructor;
  uint256 value;
  bytes input;
}

Properties

Name	Type	Description
`bytecodeHash`	`bytes32`	The bytecode hash to put on an address.
`newAddress`	`address`	The address on which to deploy the bytecodehash to.
`callConstructor`	`bool`	Whether to run the constructor on the force deployment.
`value`	`uint256`	The `msg.value` with which to initialize a contract.
`input`	`bytes`	The constructor calldata.
