Erc1155InputExplicitFacet

This explicit facet handles the configuration of input packets for staking campaigns and facilitates the transfer of these input packets.

_This implementation is designed for use in staking campaigns where the input packet is not solely constructed from ERC1155 tokens (any other ERC can be accounted for if the respective explicit facet is available). However, this implementation only handles the configuration and transfer of ERC1155 tokens within the input packet.

IMPORTANT:

• This implementation should awlays be used in conjuction with the TransferInputMixer.sol.
• An input packet can encapsulate one (e.g., tokenA of ID X) or more (e.g., tokenA of ID X, tokenA of ID Y, ..., tokenX of ID Z) ERC1155 tokens._

CampaignERC1155InputConfigured

event CampaignERC1155InputConfigured(uint256 campaignId, address[] tokenAddresses, uint256[] tokenIds, uint256[] amountOfTokensPerPacket)

Emitted at setCampaignTransferErc1155Input().

CampaignERC1155InputPacketAssetsTransferred

event CampaignERC1155InputPacketAssetsTransferred(uint256 campaignId, address from, address to, uint256 amountOfPackets)

Emitted at transferErc1155Input().

setCampaignTransferErc1155Input

function setCampaignTransferErc1155Input(uint256 campaignId, bytes campaignTransferErc1155InputData) external

Setter function for configuring the ERC1155 assets within the input packet for the specified staking campaign. This function configures only the content of the input packet associated with ERC1155 assets.

_selector: 0xfcf99fea

Setter functions are executed during the creation process of campaigns (see CampaignCreationSkeleton.sol)

Requirements:

• The tokenAddresses, tokenIds and amountOfTokensPerPacket arrays must have the same length.
• tokenAddresses must contain valid, non-zero ERC1155 token addresses.
• amountOfTokensPerPacket must contain non-zero values.

Emits a {CampaignERC1155InputConfigured} event.

IMPORTANT:

• The input packet should not encapsulate only ERC1155 tokens; for configurations involving only ERC1155 tokens, use ERC1155InputFacet.sol instead.

• The values in amountOfTokensPerPacket should be in whole units, since ERC1155 tokens do not have decimal places. ----------------------------------------------------------------------------------------------------------------_

Parameters

transferErc1155Input

function transferErc1155Input(uint256 campaignId, address from, address to, uint256 amountOfPackets) external

Transfers the ERC1155 assets associated with the specified amount of a given campaign's input packets from the from address to the to address.

_selector: 0x38065473

This function iteratively executes transfers for all respective amounts of the ERC1155 tokens defined in the campaign's input packet (see setCampaignTransferErc1155Input()) in a single transaction.

The amounts to be transferred are calculated as amountOfTokensPerPacket[i] * amountOfPackets for each ERC1155 token in the input packet, where i is the index of the token in the tokenAddresses array. The transfer is performed using the safeTransferFrom method of the ERC1155 token interface.

Emits a {CampaignERC1155InputPacketAssetsTransferred} event._
