Bitcoin's base layer was never built to be used at scale, only to be held. That is what leaves the hardest money ever made sitting idle.
Not expressive
Bitcoin's scripting layer was intentionally limited: no smart contracts, no lending markets, no automated strategies
everything advanced is built elsewhere
Not quantum-resistant
Researchers at Google, IBM, and Microsoft warn the cryptographic risk could be relevant as early as 2029
the ultimate store of value cannot afford to wait
Not private
public by default: every balance, counterparty and transaction is permanently traceable, and one address linked to an identity exposes the whole financial history
spending, payroll and DeFi positions cannot stay private
Satoshi noted in 2010 that ZK proofs could make Bitcoin "much better."
Not scalable enough
slow blocks, fee spikes, a handful of transactions per second
Bitcoin's base layer was never designed for global financial activity at scale
What it costs

Centralized wrappers dominate
WBTC and its alternatives control most Bitcoin in DeFi. These rely on custodians, legal agreements, and institutional trust, the exact model Bitcoin was built to replace.
Trust assumptions everywhere
Bridges introduce layers of custodial risk. Without a trustless settlement path, "Bitcoin DeFi" remains a marketing claim built on the same fragile infrastructure as traditional finance.
Fragmented liquidity
Bitcoin's capital is scattered across dozens of chains with no unified DeFi layer. This reduces efficiency, increases friction, and splits ecosystems that should compound on each other.
<1%
Less than 1% of all Bitcoin participates in DeFi. At today's market cap, that is more than $1.5T in capital sitting idle. Bitcoin is the largest pool of capital in crypto, yet most of it remains financially inactive. Not because demand is missing. Because the infrastructure doesn't exist yet.

Why the moment is now
Catalyst
NOW01 / 04
Demand signal
Bitcoin holders want more than HODLing
The desire is real and growing: borrow against BTC, access stablecoins, earn yield, preserve privacy, get better UX, all without giving up custody, security, or the values that made Bitcoin worth holding in the first place.
Technical unlock
Institutional capital is arriving, and it wants to work
With spot ETFs and corporate treasuries, Bitcoin has entered the balance sheets of the largest financial players in the world. This capital does not want to sit idle: it wants secure, non-custodial ways to earn, collateralize, and deploy BTC. The demand is institutional-grade. What's missing is institutional-grade infrastructure.
Urgency
Quantum risk is pricing in now
Capriole estimates that Bitcoin may already be trading with a 20% quantum discount factor for 2026. This is alarming for a specific reason: Bitcoin is notoriously slow to upgrade, often taking years to reach consensus on any change, while governments, Big Tech, and researchers have converged on the same window, with quantum risk becoming relevant as early as 2029. The clock is already running, and Bitcoin has the least room to wait.
Strategic window
The technology to fix Bitcoin is finally ready
What was research a decade ago is now production-grade. STARK proofs are battle-tested, account abstraction is live, and protocol-level privacy has reached production. After more than ten years of building the exact stack Bitcoin needs, the pieces finally exist at the same time. This is the moment where solving Bitcoin's limitations moves from theory to execution.
The deeper risk
The deeper risk is that Satoshi's original vision never gets fulfilled. Bitcoin was never meant to be only digital gold.
If Bitcoin's execution layer stays unsolved or gets captured by opaque intermediaries, the asset survives, but its founding promise to billions of people quietly dies.
03
Bitcoin settles, Starknet adds the rest: DeFi, privacy, and quantum security.
How Starknet fixes it
Bitcoin's base layer is capped at around 7 transactions per second, by design, and that's a feature, not a bug: it keeps Bitcoin decentralized and secure as the settlement layer. But it means Bitcoin can't be the execution layer. Its fees are also unpredictable, spiking as high as ~$128 during the April 2024 halving. Starknet absorbs the execution: throughput climbing toward 10,000+ TPS, with fees around $0.01 and more headroom as the stack matures.

strkBTC · privacy
Public by default. Private by choice.
strkBTC is the first Bitcoin-backed asset with optional privacy, built on STRK20s, Starknet's protocol-level privacy primitive. With strkBTC you choose your mode: public by default, or private, where the full Starknet DeFi stack stays reachable, lend, borrow, trade and stake, without broadcasting your positions, balances and strategies to the entire world.
Public strkBTC
Behaves like a standard ERC-20. Fully composable across all of Starknet DeFi: swaps, lending, LPing, staking, and everything built next.
Shielded strkBTC
Balances and transfers are hidden from public view, with DeFi still accessible from inside the shielded state. Users prove validity without revealing sensitive financial information. Powered by STARK proofs.
strkBTC · quantum
Quantum-secure before Q-day.

Roadmap
Starknet has published a roadmap to end-to-end quantum security, covering the protocol surfaces that still need to migrate. Account Abstraction is making migration as smooth as one click: a user can move to a post-quantum secure signature in one transaction rather than waiting for a protocol hard fork.
Track record
Built by an OG team. A decade of scaling breakthroughs.
For more than a decade, again and again, what StarkWare shipped became the standard the rest of the industry later adopted, from the first production STARK prover to protocol-level privacy. Ten years of cryptographic firsts, now converging on Bitcoin.
The bridge roadmap
BTCFi-ready today. Fully trustless tomorrow.
Bitcoiners can already use the full DeFi stack on Starknet through a transparent, community-vetted federation. From there, every phase strips away trust assumptions, all the way to a fully trustless bridge once Bitcoin can verify STARK proofs natively.
Phase 1 — Now
Federation
strkBTC backed by a transparent federation: Near Intents, Xverse, Luganodes, Twinstakes, UTXO. Trust assumptions are explicit and public.

Native BTC staking, a Bitcoin first
Since late 2025, Bitcoin can be staked natively on Starknet to help secure the network and earn rewards. Starknet is the first rollup to tether its security directly to Bitcoin: BTC and STRK stake together, at a protocol-fixed 25% and 75% of total staking power.
Because rewards come from protocol economics, this yield is sustainable and tied directly to STRK's economy: as more STRK is staked, and as STRK appreciates, BTC staking rewards grow with it.
