Restaking Bitcoin: Unlocking Productive Capital Without Compromise (Interview With SatLayer’s CEO)
As the field of decentralized finance (DeFi) continues evolving, Bitcoin’s role within it is being quietly (or not so much) redefined. While the primary cryptocurrency has long stood (and perhaps, continues to) as a passive store of value, newer frameworks like restaking protocols are emerging to unlock its tremendous economic potential without altering its base-layer integrity.
In this exciting interview with Luke Xie, the co-founder and CEO of SatLayer, we explore how the concept of Bitcoin restaking could reshape its utility across DeFi.
From programmable slashing logic to multi-chain security coordination, however, restaking presents both technical hurdles and considerable opportunities. So stay tuned and let’s dive right into it.
What role do you think the Bitcoin Reserve in the US will play in decentralized finance?
The U.S. Bitcoin Reserve symbolizes mainstream validation of Bitcoin’s long-term value. While it may not directly participate in DeFi, its existence underpins trust in Bitcoin as a pristine, censorship-resistant collateral asset. This trust creates a stronger foundation for decentralized finance built on Bitcoin. The more confidence institutions and sovereign entities have in BTC, the more likely DeFi protocols are to adopt it as a core asset — unlocking composability, liquidity, and programmability that respects Bitcoin’s ethos.
What are the biggest technical challenges in bringing restaking to Bitcoin?
Xie summarized the challenges into three main groups.
Slashing programmability across diverse BVSs
Unlike traditional staking, which is typically binary (you either sign correctly or not), restaking introduces service-specific enforcement. Each BVS — whether it’s an oracle, bridge, DEX, or rollup — has its own definition of misbehavior. The challenge lies in designing slashing logic that is not only programmable and verifiable, but also flexible enough to adapt to the needs of each individual service.
Secure multi-BVS coordination
Operators often secure multiple BVSs at the same time, each with its own rules and risk parameters. Ensuring that slashing and reward logic is correctly isolated or cross-enforced — without compromising security or fairness — is a critical part of restaking infrastructure design.
Vault design and isolation guarantees
Restakers deposit BTC LSTs into vaults that connect to one or more BVSs. Each vault inherits that service’s specific slashing conditions and risk exposure. The challenge is ensuring restakers have full visibility into what risks they’re opting into, with clearly encoded slashing logic, predictable withdrawal flows, and transparent grace period mechanics.
What advantages does Bitcoin restaking offer compared to traditional staking in proof-of-stake ecosystems?
Bitcoin’s market cap is at $2.1T (as of May 23, 2025) and yet over 90% of Bitcoin sits idle — stored but unused, with its economic potential untapped. Restaking changes that. It transforms BTC from passive capital into productive, yield-generating collateral, unlocking powerful economic utility without altering Bitcoin’s base layer.
Bitcoin restaking pairs BTC’s unmatched economic credibility with a fee-based, utility-driven yield model. Unlike traditional proof-of-stake systems that rely on inflationary emissions and dilute token holders, Bitcoin restaking is built on real services and real demand.
Restaked BTC is used to secure Bitcoin Validated Services (BVSs) — decentralized use-cases like on-chain insurance coverage and liquidity float provisioning — that generate protocol-level fees from day one. This means restakers earn sustainable, non-inflationary yield based on the actual economic value they contribute, not just for locking up capital.
With SatLayer, restaked BTC doesn’t just secure a single chain — it can support a modular, multi-chain ecosystem, from rollups and bridges to oracles and appchains. Restakers gain exposure to multiple sources of real yield without being tied to any one protocol’s inflation schedule.
What does a “productive BTC” world look like in the next 2–3 years, and what needs to happen to get there?
A “productive BTC” world is one where Bitcoin is no longer just a passive store of value — it’s actively securing decentralized systems, earning real yield, and serving as pristine collateral across DeFi and real-world applications.
In this future, BTC is restaked to secure critical infrastructure like oracles, rollups, bridges, and appchains. The rewards aren’t driven by inflation or speculative tokenomics, but by delivering tangible, economically valuable security to networks that need it. The yield is real — paid by users and applications that derive genuine utility and trust from Bitcoin’s economic weight.
At the center of this transformation is SatLayer — the protocol that connects BTC holders, emerging protocols, and real economic activity.
To make this future a reality, SatLayer is, from day one, onboarding Bitcoin Validated Services (BVSs) — revenue generating decentralized services that rely on Bitcoin-backed restaking to function securely — in order to generate sustainable, real, protocol-level fees.
This design promotes a crucial mindset shift: BTC holders are no longer just “hodling” — they’re empowered to put their assets to work and earn sustainable, ecosystem-driven yield.
As this takes hold, it sets off a self-sustaining, incentives-aligned flywheel:
- BTC enters productive restaking via SatLayer.
- Protocols gain Bitcoin-backed security, boosting their credibility and resilience.
- Restakers earn real sustainable yield, increasing Bitcoin’s utility and appeal.
- That yield attracts more BTC into the system, amplifying its security guarantees.
- More projects choose to build on Bitcoin-backed security, unlocking even more yield opportunities.
With SatLayer as the foundation, BTC evolves from digital gold into the economic engine of a secure, decentralized future.
How is SatLayer approaching security and slashing risks in a modular, multi-chain restaking model?
Built with a security-first mindset, SatLayer’s core infrastructure undergoes quarterly third-party audits by leading security firms, along with continuous testing and formal verification of critical components.
But SatLayer’s real innovation lies in how it handles risk: through programmable, application-specific slashing. Unlike traditional staking models with one-size-fits-all penalties, SatLayer enables each Bitcoin Validated Service (BVS) to define its own slashing logic — customized to its specific use case, security requirements, and threat model.
Example: In the context of an on-chain coverage BVS, Bitcoin restakers provide security guarantees for underwriting smart contract risk or protocol failures. In the event that an insured protocol fails — due to a hack, smart contract bug, liquidation shortfall, or depeg — programmable logic can trigger a slash and initiate payouts. Essentially, BVSs act as decentralized claims adjudicators — ingesting on-chain events, oracle data, and even off-chain proofs to verify claims and execute coverage.
This modular, opt-in security model ensures that Bitcoin restakers are only ever exposed to risks they explicitly accept, with full visibility into each BVS’s slashing logic and parameters before delegating capital.
By combining audit-grade infrastructure with programmable risk management, SatLayer brings Bitcoin-grade assurance to a dynamic, restaking environment — all while preserving sovereignty and minimizing unintended exposure.
How can Bitcoin’s credibility and SatLayer’s infrastructure help rebuild trust in decentralized finance?
The 2022–2023 wave of DeFi failures exposed the dangers of over-financialization and opaque, mispriced risk. Bitcoin offers a counterweight — with monetary clarity, fixed supply, and a neutral, non-inflationary baseline.
And SatLayer extends that clarity into DeFi.
By enabling BTC to secure protocols through restaking — in a transparent, opt-in way — it replaces governance-heavy systems with code-enforced trust.
When decentralized services are underpinned by Bitcoin’s credibility and SatLayer’s modular, verifiable economic layer, they gain stronger guarantees, are fundamentally more resilient — and become more aligned with the original values of decentralization: trustless execution, transparent logic, user sovereignty, and censorship resistance.
What’s a major misconception the crypto community has about Bitcoin’s potential role in DeFi?
A major misconception in the crypto community is that Bitcoin can’t play an active role in DeFi — that it’s only useful as a passive store of value, not as programmable collateral.
This belief stems from Bitcoin’s deliberately minimal scripting model and the absence of native smart contracts. As a result, many assume that BTC must be wrapped, bridged, or fundamentally compromised to participate in decentralized applications.
But that’s changing.
Protocols like SatLayer challenge this assumption head on — introducing restaking and slashing mechanisms that extend Bitcoin’s utility without sacrificing its core principles. Through opt-in vaults, verifiable operator behavior, and programmable economic enforcement, Bitcoin can now provide real, cryptoeconomic security to services like oracles, insurance, bridges, and liquidity layers — without being bridged or reissued.
The real misconception is underestimating how far credibility, transparency, and programmable enforcement can go when composed with intention.
With a modular framework like SatLayer, Bitcoin transforms from passive digital gold into an active foundation for a new financial economy — one that’s secure, programmable, and trustless by design.

Ethereum continues to show strong momentum as the price hovers just under a key level, supported by sustained bullish structure and growing market interest. With spot prices holding above major moving averages and an aggressive rally from June lows, all eyes are on whether ETH can break above the $4,107 level.
Technical Analysis
By ShayanMarkets
The Daily Chart
On the daily chart, Ethereum is respecting its bullish structure, having flipped the $3,300 zone from resistance into support. The 100-day and 200-day have also created a bullish crossover, providing additional confirmation of the trend.
Moreover, the RSI, which recently entered overbought territory, has slightly cooled down but remains elevated, suggesting that momentum might be overheated. Yet, the clean sweep and reclaim of prior highs around $3,300 reflect strength and commitment from buyers, and as long as this level holds, the bulls are in control.
This structure is a classic sign of trend continuation, especially when supported by strong volume and momentum indicators. If the price begins to expand again from this consolidation range, the next upside target would likely be the $4,400 region, where Ethereum topped during previous cycles.
Conversely, a break below $3,300 would raise concerns of a deeper retracement, but for now, that scenario seems less likely unless broader market weakness emerges.
The 4-Hour Chart
The 4H chart further supports the bullish case with a clearly defined ascending trendline holding the price. The asset continues to respect the trendline, and each dip has been met with strong buying interest, signaling that bulls are still active and defending the uptrend.
However, some caution is warranted in the short term, mainly due to the overbought conditions on the daily chart. If ETH fails to hold above the $3,700 zone or loses the ascending trendline, a short-term correction toward $3,500 would be a healthy reset. This level also aligns with the daily support block, making it a logical area for buyers to step in again if tested.
On-Chain Analysis
Ethereum Open Interest
On the sentiment side, Ethereum’s open interest across all exchanges has surged to over $27 billion, marking its highest point in years. This indicates a massive influx of leveraged positions and reflects growing speculative appetite in the market. Historically, rising open interest in tandem with rising price signals confidence and trend strength, but it also increases the risk of a long squeeze if the market turns.
What’s notable, however, is that despite the elevated OI, funding rates remain at relatively moderate levels. This suggests that the majority of traders are not excessively over-leveraged, and we are not yet seeing the kind of euphoria typically associated with major tops.
It gives Ethereum more room to push higher without the immediate threat of a sharp deleveraging event. For now, positioning remains optimistic but not overheated, keeping the path open for a potential breakout above $4,100.

Just a few weeks after announcing new 30% tariffs against the European Union and Mexico, US President Donald Trump sat down with the former’s leader to discuss deal terms.
The meeting between Ursula von der Leyen and Trump in Turnberry, Scotland, appeared to be productive, as both parties said they reached a framework for a trade deal.
According to details shared by CNN, the EU has agreed to purchase $750 billion worth of energy from the US, as well as invest an additional $600 billion.
The initial 30% tariffs on almost all goods, aside from steel and aluminum, which will be set at 50%, were announced two weeks ago and were supposed to be enforced starting on August 1.
Although the EU will invest the aforementioned billions in different US-related initiatives, Trump said he could not lower the tariffs any further than a 15% across-the-board taxation.
Tariff news typically impacts the cryptocurrency market, although the effects have diminished in recent months. Back in April, the entire market tumbled as Trump announced tariffs against essentially all other countries.
Now, though, any new threats or announcements lead to less volatility. Still, a few digital assets began to chart gains after the news of the new deal was released.
BNB is among the top performers in the past few hours, which resulted in a price pump to a new all-time high of over $825 minutes ago. BNB has reclaimed its spot as the fifth-largest cryptocurrency from SOL.
BTC has also risen slightly and now trades above $119,000. ETH is up by over 3% on a daily scale and sits close to $3,850.

Base, the Coinbase-incubated Ethereum Layer 2 network, has emerged as the most profitable rollup in the ecosystem, as it generated an average of $185,291 in daily revenue over the past six months.
With the latest figure, Base has far outpaced Arbitrum’s $55,025 and the combined $46,742 of 14 other top Layer 2s.
Base Captures Majority of L2 Market Share
In its latest analysis, Galaxy Digital explained that Base’s lead is supported by its EIP-1559-inspired fee model, which enables “dynamic” auction-based priority fee collection rather than strict first-come-first-served (FCFS) ordering.
The sequencer prioritizes transactions based on the highest priority fee per unit of gas and allows users to pay premiums for urgent execution. This enables Base to monetize block space demand efficiently.
Ethereum’s Pectra upgrade, which reduced Layer 1 posting costs via blob-enabled data submission, has further improved Base’s efficiency in monetizing block space while maintaining low transaction fees.
While Arbitrum introduced Timeboost in April 2025 to enable slot-bidding for express execution, it remains a predictive, fixed-rate system that is less reactive than Base’s per-transaction bidding. This makes the former less effective at capturing sudden spikes in user demand.
Over the past six months, priority fees alone have averaged $156,138 per day for Base. The chain accounted for about 86% of its daily revenue. Transactions occupying the top slot of each block contributed 30%-45% of daily revenue year-to-date in 2025, while the top 10 slots have accounted for between 50%-80% of daily revenue over the same period.
Meanwhile, “Flashblocks,” which was implemented on the Layer 2 network on July 16, introduced sub-block confirmations that allow high-priority transactions to land in lower slots while still receiving near-instant execution. This has resulted in a more even distribution of priority fees across block slots without reducing overall fee generation. Such a system in place has helped Base maintain strong revenue capture despite changes in slot allocation.
Base’s Revenue Engine
It is important to note that Base’s dominance in decentralized exchange (DEX) activity has been a major driver of its revenue. The network has consistently captured 50%-65% of Layer 2 DEX volume and holds the highest DEX TVL among Layer 2s, excluding perpetual DEX platforms.
Historically, priority fees tied to DEX swaps contributed 50%-70% of daily fees paid to Base. However, this share has declined to around 34% in recent weeks and reflects increased base fees and growing non-DEX competition for block space across the network. Despite this dip, DEX swaps have been observed to be a primary contributor to Base’s fee generation, especially in time-sensitive trades and maximum extractable value (MEV) strategies.
Data also indicates that a small cohort of users dominates priority fee payments, with 250 addresses accounting for nearly 65% of all priority fees paid over the past year.
