Stacks is a Bitcoin Layer-2 network that enables smart contracts and decentralized applications to use Bitcoin as a secure base layer. The SIP-031 Interim Grants was a time-bound funding program operated by the Stacks Foundation to serve as a bridge to the Stacks Endowment. It provided short-term capital to active ecosystem builders ahead of the full Stacks Ecosystem Grants Program launch. The initiative distributed funding across three paths: High TVL direct outreach, Open-Ended GitHub applications, and community-led DeGrants, ultimately supporting 24 out of 30 complete applications.
The Stacks SIP-031 Interim Grants program provided a temporary bridge of funding opportunities for active ecosystem builders prior to the launch of the Stacks Endowment. Participants began by reviewing the official announcement to determine their eligibility, with a strong preference given to existing, open-source projects that demonstrated clear traction metrics such as active users, transaction volume, or Total Value Locked (TVL).
Funding allocation was structured across 3 primary paths. Projects boasting over $5,000,000 in TVL were engaged directly by the Stacks Foundation for specialized needs assessments. Other active builders were instructed to submit comprehensive applications for Open-Ended Grants via the designated GitHub repository, with a strict deadline of September 30, 2025. Furthermore, newer builders and early-stage ideas were encouraged to apply for the community-led DeGrants cohort, which accepted applications between September 10 and October 8, 2025.
Applications underwent rigorous review by Stacks Foundation staff alongside community panelists. Selected grantees, such as PropertyX which was approved for a $35,000 grant covering development and ecosystem expenses, were mandated to post regular progress updates on their GitHub issue threads to maintain transparency.
Review the official announcement for program eligibility and the three available funding paths.
Wait for direct outreach from the Stacks Foundation if your project maintains over $5M in TVL.
Submit a detailed Open-Ended Grant application via the official GitHub repository by September 30, 2025.
Apply for the community-led DeGrants cohort between September 10 and October 8, 2025, if applicable.
Post regular monthly or bi-weekly progress updates on your GitHub issue thread if awarded funding.
