Functions

createWithDurationsLD

Creates a batch of Lockup Dynamic streams using createWithDurationsLD.

Requirements:

• There must be at least one element in batch.
• All requirements from {ISablierLockup.createWithDurationsLD} must be met for each stream.

function createWithDurationsLD(
    ISablierLockup lockup,
    IERC20 token,
    BatchLockup.CreateWithDurationsLD[] calldata batch

token	IERC20	The contract address of the ERC-20 token to be distributed.
batch	BatchLockup.CreateWithDurationsLD[]	An array of structs, each encapsulating a subset of the parameters of {SablierLockup.createWithDurationsLD}.

Returns

Name	Type	Description
streamIds	uint256[]	The ids of the newly created streams.

_approve

Helper function to approve a Lockup contract to spend funds from the batchLockup. If the current allowance is insufficient, this function approves Lockup to spend the exact amount. The {SafeERC20.forceApprove} function is used to handle special ERC-20 tokens (e.g. USDT) that require the current allowance to be zero before setting it to a non-zero value.

function _approve(address lockup, IERC20 token, uint256 amount) internal;

_handleTransfer

Helper function to transfer tokens from the caller to the batchLockup contract and approve the Lockup contract.

function _handleTransfer(address lockup, IERC20 token, uint256 amount) internal;
