During the hackathon, we developed Universal GRAVE (Global Reserve for Abandoned Virtual Entities), a protocol designed to tackle the growing spam problem in the Web3 space, particularly on networks with low transaction costs. Users often receive an influx of unwanted tokens, which disrupts their experience and makes curation difficult. GRAVE introduced a unique "spambox" approach that redirects unwanted tokens to a designated vault, allowing users to manage these assets with greater flexibility and control. The innovative aspect of Universal GRAVE lies in its approach to filtering and curation. By default, all unwanted fungible and non-fungible tokens are forwarded to the GRAVE vault. Users can then retrieve specific assets from the vault if they wish, providing a safe and convenient way to manage spam. The GRAVE not only enhances security and reduces spam but also allows for future community-driven curation through incentivized curators and asset auctions. The GRAVE project's innovative "opt-out" approach has the potential to set a new standard for handling spam in decentralized networks. Since launching the GRAVE on the LUKSO Mainnet in February of 2024 we’ve had 35 profiles start using it for protection.
