What's Next for Stacks: Fireblocks, Messari Q4 Report, and the Bitcoin Staking Thesis

‍A biweekly update on the biggest developments across the Stacks ecosystem.

This week brought a cluster of developments that reinforce where Stacks is heading in 2026. Fireblocks announced its integration, giving 2,400+ institutional clients access to Bitcoin DeFi on Stacks. Messari published its Q4 2025 report showing onchain growth despite a 57% STX price decline. The Stacks Endowment launched a formal grants program. And AIBTC Dev shipped Bitcoin-native AI agent tooling that's already in production. Here's what happened and why it matters.

From the Town Hall: Why These Market Conditions Play Into the Stacks Thesis

At the most recent Stacks community town hall, founder Muneeb Ali shared an observation about market cycles that reframes the opportunity ahead.

When Bitcoin price is appreciating fast, there's no incentive to do anything with your BTC. You hold it. But when price is cycling up and down, behavior changes. Holders start asking: what can I do with my Bitcoin?

That shift is creating real product-market fit. As Muneeb described it, large institutions with significant Bitcoin positions are approaching Stacks specifically about deploying BTC on-chain. Not speculating. Deploying Bitcoin productively while maintaining custody.

When Bitcoin price is appreciating a lot, people are just holding it as an investment. In the recent years, as price is going up and down in a certain range, there's a lot of interest, especialyl from institutions, in doing something with their Bitcoin. That's where we're sort of hitting product market fit, where a lot of institutions are actually coming to us about helping them deploy their BTC
━ Muneeb Ali, Stacks Founder (Stacks Townhall, February 5, 2026)

The side effect: institutions won't deploy capital until everything meets a professional standard. More custodian integrations, more compliance infrastructure, more institutional-grade tooling. And once those pieces are in place, retail follows.

CEO Alex Miller added that this changes Stacks' approach. When a huge proportion of needed liquidity is concentrated in a smaller group of institutional holders, it's about leveraging the regulatory clarity Stacks has established, owning the end-to-end experience, and producing things that work for larger entities. Once they come in with their liquidity and professional capabilities, the longer tail of users and builders follows.

Messari Q4 2025 Report: Onchain Growth Despite Market Headwinds

Messari's Q4 2025 quarterly report on Stacks provides independent data backing the thesis above.

The headline: onchain fundamentals grew while prices declined. STX price fell 57% QoQ alongside broader market weakness, but underneath that:

• DeFi TVL in native STX terms grew 120.8% QoQ to 488 million STX
• Average total STX stacked rose for the fourth consecutive quarter, up 32.4% YoY
• DeFi diversity score improved from 4 to 5, with activity spreading across more protocols
• Average daily transactions more than doubled year-over-year, up 153.5%

Capital is moving into productive use on Stacks regardless of exchange prices. Fewer participants are locking more capital, a pattern consistent with institutional behavior.

Messari's forward-looking assessment: self-custodial Bitcoin staking is expected to be the defining narrative for Stacks in 2026. Dual Stacking, launched in Q4, already ranked among the top Bitcoin-native yield strategies.

Fireblocks Integrates Stacks, Unlocking Institutional Bitcoin DeFi

Fireblocks announced its integration with Stacks this week, giving its 2,400+ institutional clients direct access to Bitcoin DeFi.

Institutions can now custody STX and sBTC, mint and bridge Bitcoin, and interact with lending, yield, and trading protocols directly from the Fireblocks console. That includes BTC-yielding vaults through Hermetica, BTC-backed loans via Zest and Granite, and BTC-native liquidity through Bitflow.

This is exactly the kind of custodian integration Muneeb referenced at the town hall. Institutions adopt when the infrastructure meets their compliance and custody requirements. Fireblocks is that infrastructure for a large portion of the institutional crypto market.

Stacks Endowment Launches Ecosystem Grants Program

The Stacks Endowment, funded through the community-approved SIP-031, launched its formal grants program this week. The program is structured around three tracks designed to meet builders wherever they are:

Builder Grants ($10,000-$50,000 in STX): For proven protocols already driving measurable impact. These are retroactive and forward-looking, rewarding teams based on onchain metrics like TVL growth, transaction volume, and infrastructure improvements.

Getting Started Grants ($5,000-$10,000 in STX): For pre-product-market-fit founders with early proof-of-concept. Seed funding for unique ideas that need a beta or pilot to demonstrate traction.

Community DeGrants (up to $5,000 in STX): Continuing the grassroots community-led funding tradition for education, content, creative projects, and cultural initiatives.

The Q1 cohort is open now through March 13, 2026. Applications are available at stacksendowment.co/grants.

Two details worth flagging. First, the Endowment is committing to public documentation of who gets funded, why, and what they delivered. A live onchain grants tracker is planned for March 2026. Second, they're building in retroactive rewards, meaning teams already shipping and showing traction can earn grant funding for work that's already been done. That's a meaningful signal to builders who have been contributing without formal support.

The framing from the Endowment puts the opportunity in perspective: only about 1% of Bitcoin is deployed onchain today. The builders who figure out how to activate the other 99% are working on the largest untapped opportunity in crypto.

AI Agents Are Getting Bitcoin Superpowers on Stacks

AIBTC Dev, an open-source project building Bitcoin-native tooling for AI agents, shipped a major update this week. Their MCP server now gives AI agents a full suite of capabilities: BTC wallets, onchain identity, x402 payments, DeFi and yield access, smart contract deployment, and more. All open-source, no custody, Bitcoin-native.

The setup is simple. An AI agent can curl aibtc.com to register and unlock the ability to create wallets, send and receive BTC, deploy smart contracts, bridge BTC to sBTC, lend and borrow through Zest, execute swaps through Bitflow, and register BNS names. One developer reported going from zero to fully installed with a wallet in three minutes using Claude Code.

While most Bitcoin projects are just now exploring the AI agent narrative, AIBTC Dev has been building for over a year. Their stack already supports L1, L2 via Stacks, x402 payments, lending, DeFi swaps, leverage, and yield. As AI agents become more autonomous, they'll need trustless, self-custodial financial infrastructure. Bitcoin's security and Stacks' programmability are a natural fit.

Looking Ahead

The Messari Q4 report will be publicly available shortly. Fireblocks integration rollout continues through Q1. Endowment grant applications close March 13. And on the self-custodial Bitcoin staking front: more is coming.
