Description
ERC721RA is an improved implementation of ERC721A with refundability and gas saving features. It allows NFT minters to return NFTs for a refund, which helps prevent rugpulls and improves the credibility of creators. The standard supports minting multiple NFTs to significantly reduce gas costs, simplifies coding with its built-in features, and aims to foster higher floor prices for trusted collections. It also facilitates fair NFT launches through easy implementation of gas-saving randomness with Chainlink VRF V2.
