fee config for calcFee(). Configurable by owner.

avoVersions

mapping(address => bool) avoVersions

mapping to store allowed Avocado versions. Modifiable by owner.

AvoRegistryCore

AvoFeeCollector

calcFee

function calcFee(uint256 gasUsed_) public view returns (uint256 feeAmount_, address payable feeCollector_)

calculates the feeAmount_ for an Avocado (msg.sender) transaction gasUsed_ based on fee configuration present on the contract

Parameters

Name	Type	Description
gasUsed_	uint256	amount of gas used, required if mode is percentage. not used if mode is static fee.

Return Values

Name	Type	Description
feeAmount_	uint256	calculated fee amount to be paid
feeCollector_	address payable	address to send the fee to

updateFeeConfig

function updateFeeConfig(struct IAvoFeeCollector.FeeConfig feeConfig_) external

sets feeConfig_ as the new fee config in storage. Only callable by owner.

AvoRegistry

constructor

constructor(contract IAvoFactory avoFactory_) public

initialize

function initialize(address owner_) public

initializes the contract with owner_ as owner

requireValidAvoVersion

function requireValidAvoVersion(address avoVersion_) external view

checks if an address is listed as allowed Avocado version, reverts if not.

Parameters

Name	Type	Description
avoVersion_	address	address of the Avocado logic contract to check

requireValidAvoForwarderVersion

function requireValidAvoForwarderVersion(address avoForwarderVersion_) external view

checks if an address is listed as allowed AvoForwarder version, reverts if not.

Parameters

Name	Type	Description
avoForwarderVersion_	address	address of the AvoForwarder logic contract to check

setAvoForwarderVersion

function setAvoForwarderVersion(address avoForwarder_, bool allowed_) external

sets the status for a certain address as allowed AvoForwarder version. Only callable by owner.

Parameters

Name	Type	Description
avoForwarder_	address	the address of the contract to treat as AvoForwarder version
allowed_	bool	flag to set this address as valid version (true) or not (false)

setAvoVersion

function setAvoVersion(address avoVersion_, bool allowed_, bool setDefault_) external

sets the status for a certain address as allowed / default Avocado version. Only callable by owner.

Parameters

Name	Type	Description
avoVersion_	address	the address of the contract to treat as Avocado version
allowed_	bool	flag to set this address as valid version (true) or not (false)
setDefault_	bool	flag to indicate whether this version should automatically be set as new default version for new deployments at the linked avoFactory

renounceOwnership

function renounceOwnership() public view

override renounce ownership as it could leave the contract in an unwanted state if called by mistake.
