StartupGovernor
Inherits: MezzGovernor, MezzEIP712, NoncesUpgradeable, IStartupGovernor
Author: Daniel Yamagata
A governance contract that enables the execution of arbitrary transactions by a super-majority of a treasury's signers. A super majority is counted as two-thirds of the signers rounded upwards. Below is a table with a few examples.
The execution of transactions requires an arbitrary deadline. If this deadline passes, the transaction will revert even if provided the correct number of signatures.
State Variables
EXECUTE_TYPEHASH
Functions
constructor
init
Intializes the Governor's state
Parameters
__Startup_Governor_init
The 'params' argument is maintained in case future versions require additional initialization parameters
executeTx
Executes an arbitrary transaction. Requires a super majority of board members to sign off
Signatures must be packed in ascending order of the public addresses of the signers and must be packed into a single variable.
Parameters
Returns
_checkNSignatures
Validates the 'signatures' and the number of required signatures for 'safeCache', '_hash', and '_hashData'
_execute
Executes a call on a given 'target' with 'data' and 'value'. Reverts if the call fails or the target's code length is zero
getExecuteTransactionHash
Returns the transaction hash of the encoded execute data.
This hash is the one to be signed by a private key. Signatures should then be packed in ascending order by the public keys of the owners when calling executeTx()
Parameters
encodeExecuteData
Encodes a StartupGovernorExecute struct hash following the EIP-191 signed typed data standard
Reference: https://eips.ethereum.org/EIPS/eip-191
Parameters
getExecuteStructHash
Returns the hash of a StartupGovernorExecute struct following the EIP-712 encoding standards
Reference: https://eips.ethereum.org/EIPS/eip-712
Parameters
coreId
Returns the coreId of the implementation as a bytes32
The core ID is the keccak256 hash of the contract name followed by a version under the following syntax: "mezzanine.coreId.ContractName.vX" For example, the core ID of the 2nd version of the Treasury would be the following: keccak256(abi.encodePacked("mezzanine.coreId.Treasury.v2"))
version
Returns the version of the implementation as a uint256
