The Gitcoin Grants 21 (GG21) initiative is nearing its conclusion, with just hours remaining for contributors to support various projects through Quadratic Funding. The final rounds of donations are set to end within the next 24 hours, with a call to action for supporters to contribute to their favorite projects. Gitcoin has emphasized the importance of every donation, highlighting the impact that small contributions can make. Additionally, there will be an extended shill space event to celebrate the closing of GG21, featuring discussions and talks, including one at ETH CC with notable sponsors such as Public Nouns and RabbitX. As the deadline approaches, Gitcoin encourages participants to finalize their donations and join the community in supporting public goods.
