The Gitcoin Grants 21 project has officially launched, with the goal of boosting the capacities of external communities through joint efforts with partners. This event will last until August 22, 7:59 PM, with a focus on strengthening community building and encouraging collaborative development. This round of Gitcoin Grants includes cycles for both the Celo and Arbitrum ecosystems, as well as nine distinct community cycles, providing a wide range of collaboration opportunities for participants. It's worth noting that this round does not require users to collect Passport stamps, instead providing technical assistance through the Gitcoin Grants Stack, simplifying the participation process and making it easier for more people to participate in this significant effort to enhance community capacities.
