Stackers, that’s a wrap on SIP-031 voting with over 310m STX cast in support of this ecosystem ‘growth round’. The vote, a record in total STX voting power, passed with over 97% of all voting power cast in favor of creating the new Stacks Endowment that will enable the next phase of growth for Stacks while becoming a long-term backstop for the ecosystem.

The proposal comes on the heels of sBTC’s TVL rapidly reaching $600M, which puts Stacks ahead of all other Bitcoin layers and major refresh of the Stacks Roadmap. In addition to creating the new capital necessary to lean into this recent growth, and technical progress the SIP outlines how core contributors will streamline entities to best support the current needs of the ecosystem and optimize for today’s crypto industry. Through minimal tweaks to overall inflation, SIP-031 will create 500m STX over five years for the Stacks Endowment, which will enable further investment in marketing, integrations, DeFi incentives, developer and founder incentives, and much more. Stacks will remain well below the median inflation rate for Top 50 projects by market cap and be able to build a treasury that is better suited for the caliber of the project, the current landscape, and the scope of its mission to unlock the Bitcoin economy. You can learn more about the rationale and research behind the community’s decision to fund this effort in the complete SIP.

In this post, we’ll break down the voting results and outline what you can expect following the end-of-month hard fork that will implement the SIP.

SIP-031 was a community-wide effort, shaped by voices from every corner of the ecosystem, core contributors, investors, partners, and domain experts. A recent builder guest post breaks down how the community’s voice was central to the process and discusses the various stages of the SIP’s life cycle. From early drafts to multiple AMAs and feedback loops, this SIP evolved in real time with input from everyone, including institutional players and advisory boards. We want to thank everybody who engaged with the process. 🧡

97.5% of all STX cast were in favor of SIP-031. The vote saw record STX voting power, becoming the first SIP to pass 300M in total STX cast with 303M+ in favor.

With SIP-031 passing decisively, the Stacks ecosystem is poised to continue its momentum and double down on growth efforts, particularly those laid out in the Stacks roadmap and SIP. Work is already underway to implement everything called for in the SIP, let’s take a look at the next big steps:

July:

• ✅ Complete vote, audit, and share results
• ✅ Endowment smart contract written
• Endowment smart contract tested and audited (in progress)
• Establish and share the public Stacks Endowment wallet address
• Provide hard fork upgrade code to network operators on 7/30/2025 (pending smart contract audit results)
• Appointments Committee begins work to select Treasury Committee

August/September:

• Legal entity formation (Endowment, Operational Entity, etc.)
• Remaining Treasury Committee seats filled by the Appointments Committee
• Builder and community workshops on workstreams like:

🔸 Grant programs (DeFi incentives, retroactive programs, DeGrants, etc.)
🔸 Dual-Stacking & sBTC Yield Product Strategy Sessions
🔸 Upcoming SIPs: Stacking simplification, Larry’s SIP

• Working Group refreshes (Stacks Foundation)
• Governance refreshes related to SIP Steering Committee and CABs
• Initial one-off grants from the Endowment for areas of clear/high need
• Key positions opened and recruiting begun (CEO and CMO at Operational Entity, CIO at Stacks Endowment, etc.)
• Establish a web presence for Stacks Endowment

Fall 2025:

• Launch of new Grant opportunities (Stacks Endowment)
• Ramp up hiring at Operational Entity
• Ramp up of DeFi deployments

Hiring dependent H2 2025:

• Launch of new Stacks marketing campaigns
• Launch of new programs supporting app-level growth and security
• Launch of new programs supporting builder fundraising, TGEs, and company growth

Note that these items apply to the new Endowment and Operational Entity; the Stacks Roadmap remains the go-to resource for product, growth, and technical goals.

As per the SIP, the hard fork is expected at Bitcoin block 907740, currently projected to arrive on Tuesday, July 29th, at approximately 7am UTC (3am ET). Network operators will be provided with the upgrade resources on the usual channels.
