LockPaymentCondition

Implementation of the Lock Payment Condition This condition allows to lock payment for multiple receivers taking into account the royalties to be paid to the original creators in a secondary market.

Functions¶

initialize¶

  function initialize(
    address _owner,
    address _conditionStoreManagerAddress,
    address _tokenAddress,
    address _didRegistryAddress
  ) external

initialize init the contract with the following parameters

this function is called only once during the contract initialization.

Parameters:¶

Name	Type	Description
`_owner`	address	contract's owner account address
`_conditionStoreManagerAddress`	address	condition store manager address
`_tokenAddress`	address	Default Token contract address
`_didRegistryAddress`	address	DID Registry address

hashValues¶

  function hashValues(
    bytes32 _did,
    address _rewardAddress,
    address _tokenAddress,
    uint256[] _amounts,
    address[] _receivers
  ) public returns (bytes32)

hashValues generates the hash of condition inputs with the following parameters

Parameters:¶

Name	Type	Description
`_did`	bytes32	the asset decentralized identifier
`_rewardAddress`	address	the contract address where the reward is locked
`_tokenAddress`	address	the ERC20 contract address to use during the lock payment.
If the address is 0x0 means we won't use a ERC20 but ETH for payment
`_amounts`	uint256[]	token amounts to be locked/released
`_receivers`	address[]	receiver's addresses

Return Values:¶

Name	Type	Description
`bytes32`	bytes32	hash of all these values
### fulfill
`function fulfill( bytes32 _agreementId, bytes32 _did, address payable _rewardAddress, address _tokenAddress, uint256[] _amounts, address[] _receivers ) external returns (enum ConditionStoreLibrary.ConditionState)`
fulfill requires valid token transfer in order
to lock the amount of tokens based on the SEA

Parameters:¶

Name	Type	Description
`_agreementId`	bytes32	the agreement identifier
`_did`	bytes32	the asset decentralized identifier
`_rewardAddress`	address payable	the contract address where the reward is locked
`_tokenAddress`	address	the ERC20 contract address to use during the lock payment.
`_amounts`	uint256[]	token amounts to be locked/released
`_receivers`	address[]	receiver's addresses

Return Values:¶

Name	Type	Description
`condition`	bytes32	state
### _transferERC20
`function _transferERC20( address _rewardAddress, address _tokenAddress, uint256 _amount ) internal returns (bool)`
_transferERC20 transfer ERC20 tokens

Parameters:¶

Name	Type	Description
`_rewardAddress`	address	the address to receive the tokens
`_tokenAddress`	address	the ERC20 contract address to use during the payment
`_amount`	uint256	token amount to be locked/released

Return Values:¶

Name	Type	Description
`true`	address	if everything worked
### _transferETH
`function _transferETH( address payable _rewardAddress, uint256 _amount ) internal`
_transferETH transfer ETH

Parameters:¶

Name	Type	Description
`_rewardAddress`	address payable	the address to receive the ETH
`_amount`	uint256	ETH amount to be locked/released
