The Unlock Interface*
Methods​ computeAvailableDiscountFor​ function computeAvailableDiscountFor(address _purchaser, uint256 _keyPrice) external view returns (uint256 discount, uint256 tokens) Copy This function returns the discount available for a user, when purchasing a a key from a lock. This does not modify the state. It returns both the discount and the number of tokens consumed to grant that discount.
Parameters​ Name Type Description _purchaser address undefined _keyPrice uint256 undefined
Returns​ Name Type Description discount uint256 undefined tokens uint256 undefined
configUnlock​ function configUnlock(address _udt, address _weth, uint256 _estimatedGasForPurchase, string _symbol, string _URI) external nonpayable Copy Allows the owner to update configuration variables
Parameters​ Name Type Description _udt address undefined _weth address undefined _estimatedGasForPurchase uint256 undefined _symbol string undefined _URI string undefined
createLock​ function createLock(uint256 _expirationDuration, address _tokenAddress, uint256 _keyPrice, uint256 _maxNumberOfKeys, string _lockName, bytes12 _salt) external nonpayable Copy Create lock This deploys a lock for a creator. It also keeps track of the deployed lock.
Parameters​ Name Type Description _expirationDuration uint256 undefined _tokenAddress address set to the ERC20 token address, or 0 for ETH. _keyPrice uint256 undefined _maxNumberOfKeys uint256 undefined _lockName string undefined _salt bytes12 an identifier for the Lock, which is unique for the user. This may be implemented as a sequence ID or with RNG. It's used with create2 to know the lock's address before the transaction is mined.

function owner() external view returns (address) Copy Returns the address of the current owner.
Returns​ Name Type Description _0 address undefined
publicLockAddress​ function publicLockAddress() external view returns (address) Copy Returns​ Name Type Description _0 address undefined
recordConsumedDiscount​ function recordConsumedDiscount(uint256 _discount, uint256 _tokens) external nonpayable Copy This function will keep track of consumed discounts by a given user. It will also grant discount tokens to the creator who is granting the discount based on the amount of discount and compensation rate. This function is invoked by a previously deployed lock only.
Parameters​ Name Type Description _discount uint256 undefined _tokens uint256 undefined
recordKeyPurchase​ function recordKeyPurchase(uint256 _value, address _referrer) external nonpayable Copy This function keeps track of the added GDP, as well as grants of discount tokens to the referrer, if applicable. The number of discount tokens granted is based on the value of the referal, the current growth rate and the lock's discount token distribution rate This function is invoked by a previously deployed lock only.
Parameters​ Name Type Description _value uint256 undefined _referrer address undefined
renounceOwnership​ function renounceOwnership() external nonpayable Copy Leaves the contract without owner. It will not be possible to call onlyOwner functions anymore. Can only be called by the current owner. NOTE: Renouncing ownership will leave the contract without an owner, thereby removing any functionality that is only available to the owner.*
resetTrackedValue​ function resetTrackedValue(uint256 _grossNetworkProduct, uint256 _totalDiscountGranted) external nonpayable Copy Parameters​ Name Type Description _grossNetworkProduct uint256 undefined _totalDiscountGranted uint256 undefined
setLockTemplate​ function setLockTemplate(address payable _publicLockAddress) external nonpayable Copy Upgrade the PublicLock template used for future calls to createLock.
This will initialize the template and revokeOwnership.
Parameters​ Name Type Description _publicLockAddress address payable undefined
setOracle​ function setOracle(address _tokenAddress, address _oracleAddress) external nonpayable Copy allows the owner to set the oracle address to use for value conversions setting the _oracleAddress to address(0) removes support for the token
This will also call update to ensure at least one datapoint has been recorded.
Parameters​ Name Type Description _tokenAddress address undefined _oracleAddress address undefined
totalDiscountGranted​ function totalDiscountGranted() external view returns (uint256) Copy Returns​ Name Type Description _0 uint256 undefined
transferOwnership​ function transferOwnership(address newOwner) external nonpayable Copy Transfers ownership of the contract to a new account (newOwner). Can only be called by the current owner.
