1/ Bold new narrative: Scaling Bitcoin + Ethereum together

Starknet will become the first L2 to settle on both Bitcoin & Ethereum, bringing the two largest blockchain ecosystems on a single layer, unlocking new DeFi opportunities and greater liquidity.

Read our vision & plan 👇

2/ Bitcoin is the OG of crypto and the ultimate store of value.

Yet, its true potential remains largely untapped; today, only ~1% of BTC is used for anything other than holding or trading.

3/ Most Bitcoin remains HODLed in wallets & CEX due to three main factors:
- Network limitations, no general-purpose computation
- Expensive to transact on the base layer
- Most BTC DeFi requires custodial or centralized solutions

4/ Bitcoin should be:
- Cheap to use: Accessible to everyone, including those who can’t afford $2+ fees per tx
- A productive asset: generating yield or engaging in DeFi without any trust assumption

This is exactly what Starknet is building for Bitcoin.

How? By becoming the execution layer for Bitcoin.

5/ Starknet as a Bitcoin L2 will improve performance and utility dramatically:

- 7 TPS → thousands of TPS (and constantly growing)
- 10 minutes block time → 2 seconds
- $2 gas fees → $0.002
- Bad UX → a smooth web2-like UX

6/ Starknet also brings Bitcoin-native DeFi apps like staking, lending, borrowing, self-custodial trading…

All secured by ZK tech and STARK proofs - the most advanced and quantum-resistant proving system.

7/ But why Starknet and not yet another L2?

Beyond performance & UX, Starknet is the most battle-tested ZK rollup, operating as a secure public L2 on Ethereum since 2021.

And Starknet was built by core contributor @StarkWareLtd, the team that:
- Invented STARK proofs
- Pioneered zkRollups, Validium, L3s, Proof Aggregation, and much more; now industry standards
- Secured over $1.3T in trading volume

That technical prowess is now coming to build on Bitcoin

8/ StarkWare has a deep history with Bitcoin.

In 2013, @EliBenSasson, StarkWare's co-founder and CEO, introduced the idea of using ZK proofs to scale blockchain for the first time at the Bitcoin conference in San Jose.

This isn’t a new narrative for us: we’ve been building towards it for over a decade.

9/ By early 2026, Starknet will be fully decentralized, meaning no central authority can censor txs on Starknet.

Providing scaling without sacrificing Bitcoin’s core values.

10/ So, why is all of this good for Bitcoiners?

- More utility: native and secure DeFi such as trading, lending/borrowing, staking, payments
- Mass adoption: super fast and affordable txs for everyone
- Web2-like UX: 2FA/3FA-powered wallets, Session Keys, Paymasters
- New fee revenue for miners: Starknet will settle on Bitcoin

11/ Why is this good for Ethereans?

- Native access to BTC as collateral → Strengthens DeFi
- New Bitcoin assets easily accessible to Ethereum users (think of Atomic swaps)
- Onboard Bitcoiners into the Ethereum ecosystem
- Create synergy & interoperability rather than competition
- More liquidity for both ecosystems

Win-win 🤝

12/ Why is this good for Starknet?

As a unifying layer, Starknet will offer exclusive features, becoming the go-to chain for the community to benefit from the innovations brought by both ecosystems.

This means more users and liquidity, attracting more developers and projects, which in turn brings even more users and liquidity… 🔄 a real virtuous cycle.

Starknet also aims to become the network with the widest range of partnerships and integrations, empowering its users to do more with their Bitcoin.

13/ To successfully achieve this vision, we are committed to developing the best possible bridge at any point in time.

1️⃣ Reputable federated bridges to bring Bitcoin assets to Starknet (coming very, very soon 👀).
2️⃣ The best BitVM-powered bridge for Starknet (the most secure Bitcoin bridge possible today).
3️⃣ In parallel, we will continue supporting research on OP_CAT, funding related public goods, and fully preparing to deploy a native and fully trustless Bitcoin bridge if OP_CAT is accepted.

We build with what’s possible right now, while simultaneously working on future innovative technology.

14/ We have also established many partnerships with top Bitcoin projects and are collaborating to build unique products.

All of this will roll out in the coming weeks.

But what if I told you… @XverseApp? And what about Bitcoin staking? 👀

15/ On top, we’re thrilled to announce that @StarknetFndn is launching a new incentive program to boost Bitcoin adoption on Starknet.

With this program, Starknet will be the best place to put your BTC to work and generate yield.

16/ Last, @StarkWareLtd, the primary contributor to Starknet, is establishing strategic BTC and ETH reserves and will continue accumulating over time.

We proudly stand with the Bitcoin and Ethereum ecosystems and growing alongside them

17/ TLDR: The Starknet on Bitcoin era is just beginning, merging the best of Bitcoin and Ethereum into a single layer and reshaping the entire market.

The past few months were all about preparation; now, it's time to deliver.
