Genius Call #25: Demystifying Ethereum Standards - Refundable NFTs & Account Abstraction - with Elie Steinbock, Founder of ShareMint Date: Wed 29 March Time: 9am PT/5pm UTC Elie Steinbock is the founder of ShareMint (https://twitter.com/sharemint_xyz) and the creator of ERC721R, the refundable NFT standard (EIP-5507). In 2018, Elie launched the CryptoFighters NFT collection. He also founded a seven-figure development agency with clients such as Mercedes & Bloomberg. In this genius call, Elie will walk us through two Ethereum Standards - the refundable NFT standard which he created (ERC721R), as well as the recent standard on account abstraction (ERC-4337), which was proposed by Vitalik Buterin and deployed in March 2023. Elie will introduce both these standards; he will explain what they are, how they work, what the goals are, the implications and the impact on web3 adoption more generally.
