Minting NFTs (non-fungible tokens) in bulk is an essential feature that developers should know how to do in order to scale their NFTs, such as NFTs using the ERC-1155 token standard.Instead of minting one NFT at a time, batch minting NFTs allows developers to bypass a time-consuming and somewhat expensive process. A great example is adding ERC721 batch transfer functions to a diamond to reduce gas for transferring many NFTs in a single transaction. No equivalent. pip install erc721 That's it, once this is setup you should be able to interact with the provided functions. Developed by Enjin, it is called, "the next generation multi-token standard.". Finally, there are some good projects that offer another view of ERC721 token efficiency: Solmate: Modern, opinionated, and gas optimized building blocks for smart contract development.

BatchTransfer is a Dapp that enables users to batch transfer NFTs, airdrop tokens or ETH safely and efficiently to one or multiple wallets in a single transaction and save 40%-70% of the transaction fee (gas). However, in the latter, a token ID has no "balance" since the tokens are non-fungible and unique. Bulk Transfer - ERC-721: Only support one token per transfer - ERC-1155: Support batch transmission of multiple token IDs in a single transaction. Transfer 3 tokens with id 15 from _from to _to. Basically, since ownership of ERC721's is based on the ownership of a unique index or id, the fundamentals of token creation and transfer need to be extrapolated to accommodate that case. This will extract all of the sales and transfer data for that desired collection and return it as a pandas dataframe.
