Batch transfer contracts for erc721 contract

erc721-batch-transfer

This function allows a user to transfer multiple ERC721 tokens to multiple recipients in a single transaction. It takes in a token contract, an array of recipients, and an array of token IDs as parameters. It first checks that the length of the recipients array is equal to the length of the token IDs array. It then loops through the token IDs array and calls the token contract's safeTransferFrom function to transfer each token to the corresponding recipient in the recipients array. (autogenerated documentation)

This function is used to transfer multiple ERC721 tokens from one address to another. It takes in three parameters: a token contract, a recipient address, and an array of token IDs. It then loops through the array of token IDs and calls the token contract's safeTransferFrom function to transfer each token from the sender to the recipient. (autogenerated documentation)

This function allows users to transfer multiple tokens from one address to another. It works by taking in three parameters: the address of the sender, the address of the recipient, and the token ID of the token to be transferred. The function then checks if the sender has the token and if the recipient is allowed to receive it. If both conditions are met, the token is transferred from the sender to the recipient. (autogenerated documentation)

This function allows users to transfer multiple tokens from one address to another. It works by allowing users to specify the address of the sender, the address of the recipient, and the token ID of the token they wish to transfer. The function then transfers the specified token from the sender to the recipient. The safeTransferFrom function is a variant of the transferFrom function that also checks to ensure that the recipient is a valid ERC-721 contract before transferring the token.
