The ERC-8021 proposal, an Ethereum-based native referral mechanism, is generating significant interest among developers. This protocol allows public chains, such as Base, to track traffic sources and incentivize developers by registering their code in a smart contract registry. Users can append these codes to transactions, enabling platforms to trace the origins of activity and distribute rewards based on transaction volume. The concept draws inspiration from Hyperliquid, aiming to enhance transparency and reward distribution in the Ethereum ecosystem.
