Stacks

Bitcoin is the largest pool of idle capital in crypto. Over $1.5 trillion sitting in wallets, ETFs, treasuries, and custody arrangements. Earning nothing.
The productivity question, what does idle Bitcoin actually do, has been answered partially.
What hasn't been solved is yield without the trade-offs. Self-Custodial Bitcoin Staking on Stacks is the first product to credibly answer that question. Lock BTC on L1, keep your keys, earn a 3% native yield paid in BTC.
That's the headline but the most interesting part is what could follow.<img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/927e637d53f640079ad007e27538c9cc.png">
<h2 id="the-funnel-how-staking-opens-the-door">The Funnel: How Staking Opens the Door</h2>
To stake, a participant locks BTC on Bitcoin L1 paired with STX on Stacks. The first tranche has been set at a 5% STX-to-BTC ratio.
That framing means a few things:
<ul>
 <li>The participant now has already crossed a friction threshold by having Stacks address with locked STX in it</li>
 <li>They're earning BTC rewards distributed via Stacks</li>
 <li>They have a reason to check the Stacks ecosystem as they have ‘skin in the game’</li>
</ul>
In product terms, Bitcoin Staking is the acquisition channel. It pulls BTC holders who may never have come for DeFi alone. They came for real yield. Once they're here, everything else becomes accessible.
This is why Self-Custodial Bitcoin Staking is the top of the Stacks funnel. The downstream effects are where the broader ecosystem case lies.
<h2 id="what-happens-inside-the-funnel">What Happens Inside the Funnel</h2>
Once BTC holders are inside the Stacks ecosystem, a predictable cascade starts.
1. Capital looks for more capital
A staker has BTC committed for around six months. That's a long time horizon. They're going to look at what else is available.
Every bond pairs BTC with STX at a 5% ratio. If STX appreciates over the six-month bond period, more of that paired STX becomes surplus at rebond. The math is direct: a participant who locked $10M of BTC and $500K of STX at the start of a cycle, and saw STX appreciate 50% over the period, now holds $750K of STX at unbond and only needs $500K to rebond at the new market price, (assuming BTC price is similar).
The remaining $250K is freed STX, available for deployment elsewhere on Stacks without unwinding the BTC position. At 100% appreciation, the freed amount doubles.<img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/4475467167674eabb62746ac79d219c4.png">
That freed STX is exactly what flows into the venues that have been waiting for it:
<ul>
 <li>Hermetica USDh &amp; hBTC are right there: a BTC-backed stablecoin that earns yield, recently picking up earn from Strategy's STRC and their new Bitcoin earn product - hBTC</li>
 <li>Zest Protocol is the lending and borrowing platform with 850+ BTC supplied. Backed by YZI Labs and Tim Draper.</li>
 <li>Bitflow's HODLMM is now live with concentrated-liquidity DEX architecture for sBTC pairs.</li>
</ul>
Each dollar deployed makes pools deeper and spreads tighter. And the participant's return profile broadens at the same time: from a single line (the 3% BTC yield from staking) to three stacked drivers running in parallel - BTC yield on the staking side, STX price exposure on the capacity-asset side, and DeFi yield on the potential freed STX deployed across the funnel.
Three return drivers, all native to the Stacks and Bitcoin economy, all reinforcing each other.
A forward-looking version of this dynamic is already being hinted at: liquid versions of the staked BTC position itself. Teams shipping on Stacks have signalled work on tokenized receipts of Bitcoin Staking bonds, comparable to how stETH made staked ETH productive across the whole of Ethereum DeFi. If those products land, the staked BTC itself becomes deployable inside Stacks DeFi while the underlying bond keeps producing its 3% native yield, layering a fourth driver on top of the three already in play.
The "capital looks for more capital" dynamic extends from the participant's other balances onto the BTC inside the bond.
2. Liquidity attracts traders
Tighter spreads attract traders. More liquid pools attract larger traders. Larger traders bring volume. Volume attracts more traders.
This is a well-understood DeFi dynamic. The trigger is initial liquidity. The funnel from Bitcoin Staking is the cleanest source of initial liquidity Stacks has ever had: long-horizon BTC capital from holders who are, by definition, not flighty.
3. Volume attracts builders
Builders go where the volume is. An active DEX with serious liquidity, a deep stablecoin market, a productive lending base. These are the conditions builders need to ship products.
More builders means more apps. More apps means the DeFi diversity score goes up (Messari's score for Stacks moved from 4 to 5 in Q4 2025; the next move to 6 looks likely with the funnel firing). Memecoin trading picks up. Agent economies activate, (AIBTC has almost 1000 agents earning BTC already; deeper liquidity makes that economy meaningfully more interesting).
4. New users discover Stacks beyond Bitcoin Staking
Once Stacks is visibly active, with high transactions, deep liquidity, and real apps, it stops being "the place where you stake Bitcoin" and becomes "the place where Bitcoin-native finance happens."
That's the broader prize. New DeFi users, traders, agents, communities show up because there's something to do.
And all of this builds on an already diverse ecosystem. Stacks mainnet has been live since 2021 and hundreds of projects and communities have formed organically here across DeFi, NFTs, community tokens, AI agents, gaming and more.<img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/73ba84e6006e4cfa9af6d7f09cefb104.png">
<h2 id="why-each-layer-benefits">Why Each Layer Benefits</h2>
Walking through the cascade primitive by primitive:
For sBTC and potential new liquid staking products: more deposits as BTC stakers explore on-chain composability. TVL peaked at $545M and has held well against the broader market downturn; the funnel pushes it higher.
For Bitflow (HODLMM): deeper liquidity in BTC-paired pools. Concentrated liquidity AMMs are most useful when volume is real; the staking funnel brings it. Recent examples of the Zest Protocol TGE are perfect here as the 1st week of volume has been 20x the liquidity pool size, ($2M vs $100k), showing real traction and attractive APYs.
For Zest: more lending deposits as stakers seek additional yield on their other capital. More borrowing demand as DeFi-native users come for the leverage. Recent native BTC deposit activation and self custodial lending and collateral markets are on the way too, further empowering the Bitcoin and Stacks economy.
For Hermetica USDh: more demand as BTC-aligned users want a BTC-backed stablecoin to operate in. Saylor mentioning USDh at the Vegas BTC Conference was a leading indicator; the funnel turns that attention into deposits.
For LeoCoin and other Stacks-native tokens: more attention from new users, more trading volume, broader ecosystem participation. Memecoins thrive on activity, and activity is exactly what the funnel produces.
For AIBTC, x402 and the agent economy: deeper rails for autonomous agents to operate on. Almost 1000 agents today; the ceiling is much higher when the underlying liquidity is real.
For builders: an active user base to ship to. The hardest part of any launch (cold-start liquidity and users) is solved by the funnel.
<h2 id="the-compounding-loop">The Compounding Loop</h2>
The output of all this activity feeds back into the Bitcoin Staking mechanism itself.
More on-chain economic activity drives transaction fees. Transaction fees expand the miner reward pool. A bigger reward pool means more BTC available to distribute as yield. More attractive yield pulls more BTC in. More BTC requires more STX as staking capacity.
Each turn of the loop runs from a larger base than the last.
) is an order of magnitude larger than ETH or SOL had at comparable points in their staking arcs.This is the same dynamic that took Ethereum from "you can stake ETH" to "DeFi runs on stETH" in two years. The mechanism is the same. The asset (Bitcoin) and the network (Stacks) are different. The pool of underlying capital that can wake up Bitcoin's $1.5T is an order of magnitude larger than ETH or SOL had at comparable points in their staking arcs.<img src="https://academy-public.coinmarketcap.com/srd-optimized-uploads/a3f3306e2d3641b0b9bde2e97f84ee35.png">
<h2 id="the-caveats">The Caveats</h2>
This is a prediction. The funnel needs to actually work for the cascade to fire.
Three things have to land:
<ul>
 <li>Bitcoin Staking has to ship cleanly in 2026 and start pulling capacity. The product is in active R&amp;D and the WP is dropping in the next few weeks. Slippage in any protocol launch is possible.</li>
 <li>The primitives downstream have to absorb the new users and capital well. UX matters. Onboarding a BTC-native holder into a DEX or a lending market is a different experience than onboarding a DeFi-native user. The teams shipping on Stacks know this; execution determines how clean the funnel actually is.</li>
 <li>The composability layer (Phase 3 of the Stacks 2026 roadmap, Bitcoin-native Finance) has to mature on schedule. Native lending, borrowing, perpetuals, sBTC as gas. Each of these unlocks a wider funnel still.</li>
</ul>
If any of those slip materially, the funnel still exists, but the cascade is slower.
<h2 id="why-we-re-watching-this">Why We're Watching This</h2>
in Dual Stacking.Tenero pays attention to Bitcoin-native networks because that's where the largest pool of idle capital is most likely to wake up first. Stacks has emerged as the leader in recent years with over 4,200 BTC distributed since 2021, $545M sBTC TVL at ATH,<a href="https://x.com/search?q=%24100M%2B&amp;src=cashtag_click" rel="noopener noreferrer nofollow">$100M+</a>
The 2026 roadmap explicitly sequences this: Anchor Capital first (Bitcoin Staking), then Scale Infrastructure (Performance), then Grow (Bitcoin-native Finance). Each phase creates the conditions for the next.
If Bitcoin Staking ships and starts anchoring institutional capital, the indicators we'll be watching are simple:
<ul>
 <li>BTC distributed per quarter</li>
 <li>Stablecoin supply on Stacks (Circle’s USDCx &amp; Hermetica’s USDh growth in particular)</li>
 <li>Trading volume on Bitflow and other DEXes</li>
 <li>Lending and borrowing activity on Zest</li>
 <li>TGE and impressive token performancePotential Stacks native protocol TGEs following<a href="https://x.com/search?q=%24ZEST&amp;src=cashtag_click" rel="noopener noreferrer nofollow">$ZEST</a></li>
</ul>
If those climb, the funnel is working, the flywheel is firing, and Stacks goes from "the place where you stake Bitcoin" to "the place where Bitcoin-native finance happens."
That's the case worth tracking through 2026.
