Solo or team.What you can build: Production-ready vault strategies. Basis trades, delta-neutral, RWA, AI-driven, or anything novel.Why: Winning strategies get seeded with real TVL (up to $1M on this track) and deployed on-chain via <a target="_blank" rel="noopener noreferrer nofollow" class="link" href="https://www.app.ranger.finance/earn">Ranger Earn</a>.
