Airdrop ERC1155

thirdweb's AirdropERC1155 contract

Airdrop ERC1155 NFTs to a list of recipients.

The AirdropERC1155 contract is suitable to use when you want to transfer ERC1155 NFTs to a list of recipient addresses, where these recipients are not expected to individually claim their airdrop; they just receive it in a transfer.

When airdropping tokens with this contract, you specify:

• The address of the Edition (ERC-1155 contract) from which NFTs are being transferred.
• The owner address of the NFTs from where the NFTs will be transferred to a list of the recipients.
• An array of objects containing recipient-address, token-ids, and amounts for e.g.

[
   {
       recipient: "0x123...",
       tokenId: 1,
       amount: 5
   },
   {
       recipient: "0xabc...",
       tokenId: 1,
       amount: 5
   }
]

note: token-owner must approve their tokens to this airdrop contract, by calling approval related functions on the ERC1155 contract.

Estimated gas costs for airdropping tokens:

Cost of airdropping 1 ERC1155 token: ~51,571 gas. Cost of airdropping each additional ERC1155 token: ~42,672 gas.
