Bitcoin builders have a three-week window to pitch their projects for funding. The Stacks Endowment opened applications for its Q2 2026 Builder Grants on June 5, closing on June 26, with decisions expected by July 1.

The grant program targets "Bitcoin-native finance," covering decentralized finance protocols, perpetual contracts, real-world asset tokenization, agentic applications, and privacy tools.

Previous grant cycles offered two tracks: Builder Grants up to $50K for established teams, and Getting Started Grants up to $10K for early-stage projects.

Applications close June 26, with a rapid five-day review period. The Endowment's recent 25 million STX donation significantly enhances its funding capacity.

Stacks is a leading Bitcoin Layer 2 solution providing smart contracts and DeFi functionality on Bitcoin. The Endowment aims to manage the ecosystem’s long-term treasury, signaling commitment to sustainable growth. Builders have until June 26 to apply, potentially accessing capital faster than traditional venture routes.
