ERC-721A - economic mint
Last updated - August 09, 2023
Toward Hemelslinn NFT's Smart Contract (THL) uses ERC-721A, the improved implementation of the IERC-721 standard that supports the minting of multiple tokens for nearly the cost of one.
ERC-721A was developed by Azuki.
What does it consist of?
As stated on the Azuki website, ERC-721A is an implementation of IERC721 with noteworthy gas savings for minting multiple NFTs in a single transaction.
The Toward Hemelslinn NFT (THL) contract will allow multiple NFTs to be minted essentially at the same cost of minting a single NFT.
The Azuki team measured gas costs and minting prices by comparing OpenZeppelin's ERC-721Enumerable with ERC-721A. The same application-level logic is used in their measurements, the only difference being the _safeMint function invoked.
Below is a summary table of the gas savings that can be achieved with ERC-721A:
