Airdrop Module

The AirdropModule (Etherscan)is a smart contract that enables managers to absorb tokens sent to the SetToken into the token's positions. With each SetToken, managers are able to specify 1) the airdrops they want to include, 2) an airdrop fee recipient, 3) airdrop fee, and 4) whether all users are allowed to trigger an airdrop.

updateFeeRecipient()

updateFeeRecipient(ISetToken _setToken, address _newFeeRecipient)

Manager only. Update address manager fees are sent to.

Parameter Name	Type	Description
_setToken	ISetToken	Instance of the SetToken

updateAirdropFee()

function updateAirdropFee( ISetToken _setToken, uint256 _newFee )

Manager only. Update airdrop fee percentage.

Parameter Name	Type	Description
_setToken	ISetToken	Instance of the SetToken
_newFee	uint256	Percentage, in preciseUnits, of new airdrop fee (1e16 = 1%)

initialize()

function initialize( ISetToken _setToken, AirdropSettings memory _airdropSettings )

Manager only. Initialize the module with SetToken and set initial airdrop tokens as well as specify whether anyone can call absorb.

Parameter Name	Type	Description
_setToken	ISetToken	Address of the SetToken
_airdropSettings	AirdropSettings	Struct of airdrop setting for Set including accepted airdrops, feeRecipient, airdropFee, and indicating if anyone can call an absorb

The AirdropSettings struct is constructed as follows:

struct AirdropSettings {
    address[] airdrops;                     // Array of tokens manager is allowing to be absorbed
    address feeRecipient;                   // Address airdrop fees are sent to
    uint256 airdropFee;                     // Percentage in preciseUnits of airdrop sent to feeRecipient (1e16 = 1%)
    bool anyoneAbsorb;                      // Boolean indicating if any address can call absorb or just the manager
