Neo co-founder Erik Zhang has finalized NEP-20, a wallet-based authentication standard that enables users to sign in to websites, games, and apps with a Neo wallet rather than usernames and passwords.

Arc is already running on a public testnet and is positioned around enterprise use cases involving USDC.
