In the three years since we launched Tané, we have invested in approximately 30 seed-stage crypto startups. Amidst high uncertainty and rapid change, we have been blessed with investments that are achieving results in ecosystems such as Ethereum and Solana. To get a feel for the market, we have experimentally operated a validator and participated in DAO governance. In DAO governance, we have partnered with a16z to participate in the governance of important protocols such as Optimism and Uniswap. As a validator, we are also working with major protocols such as Solana. Most recently, we have begun developing protocols centered on DeFi. While we still have a long way to go, based on our experience over the past three years, we have summarized "What is necessary to succeed in crypto" from six perspectives. Please take a look. We welcome your opinions and feedback, so please feel free to comment. (This article has also been contributed to the Web3 Advent Calendar 2025.) #QiitaAdventCalendar #Qiita
