Bitcoin Rollup Citrea Launches Clementine Bridge to Ease BTC Collateral Challenges in DeFi
Citrea deploys its upgraded bridge using BitVM2 on Bitcoin testnet
Key Points
Citrea is working to extend Bitcoin’s functionality by addressing the collateral barriers in connecting Bitcoin to programmable layer 2 solutions.
The project’s Clementine Bridge offers a trust-minimized solution to make BTC usable in DeFi applications.
The bridge is built using BitVM2, a programming upgrade that enhances Bitcoin’s programmability.
Citrea, a Bitcoin rollup project focused on expanding the network’s utility, has taken a major step toward integrating Bitcoin into decentralized finance (DeFi) by deploying its Clementine Bridge on the Bitcoin testnet.
The new bridge, powered by the BitVM2 programming language, aims to address one of the major hurdles in bringing BTC to programmable environments—securely bridging Bitcoin to layer 2 and sidechain ecosystems without excessive collateral requirements.
“A secure bridge between Bitcoin and a secondary layer has always been a bottleneck for using BTC in a programmable environment,” Citrea stated in a recent announcement.
Clementine is designed to overcome this issue by creating a trust-minimized process that allows BTC to be used on DeFi platforms without repeatedly locking large amounts of collateral. Traditionally, the BitVM framework required users to deposit BTC each time a computation was initiated, creating inefficiencies. Clementine improves on this by allowing operators to reuse their collateral, enabling multiple transactions—called peg-outs—with a single deposit.
Peg-outs refer to the transfer of assets from a sidechain back to the Bitcoin mainnet, where the original BTC is then unlocked and returned to the user.
This latest version of Clementine builds upon Citrea’s earlier testnet deployment from September 2024, which was based on the original BitVM model. The new version utilizes BitVM2, which introduces more flexibility and security—such as allowing any participant, not just a predefined set of operators, to challenge suspicious activity.
By tackling the collateral inefficiency and security concerns in Bitcoin-DeFi integration, Citrea’s Clementine Bridge marks a significant milestone in making Bitcoin a more viable player in the world of decentralized finance.

Learn about Rollup technology as the core, opening a new chapter in the development of BTC Layer 2
Bitcoin expansion route ≠ BTC L2.
At the beginning of the new year, I summarized the technical route of BTC L2. It is mainly divided into two parts: BTC's security and value increase, and L2 transaction execution and result downside. As time goes by, in less than three months, BTC L2 has reached nearly a hundred orders of magnitude. However, there are still some basic problems to be solved, the first of which is the definition problem.
In the history of Bitcoin development, there have long been three practical ways to expand capacity. The lowest level is the main network upgrade, such as SegWit and Taproot. The second is off-chain expansion, such as client verification, lightning network and side chain. The last is direct fork, such as Dogecoin, BSV and BCH.

Taking stock of 20 early Bitcoin Layer 2 projects worthy of attention
Welcome to Chenxi web3 vision
After the inscription craze has temporarily come to an end, Bitcoin Layer 2 people are placed with high hopes of taking over the prosperity of the Bitcoin ecosystem.
At present, Bitcoin Layer 2 is showing a momentum similar to that of Ethereum Layer 2, attracting a large number of entrepreneurs to enter the market. In addition to the well-known Layer 2 protocols such as Lightning network, Liquid Network, and Stacks, the Bitcoin ecosystem has also seen the emergence of a large number of new projects claiming to be Bitcoin Layer 2 such as B² Network, BEVM, Dovi_L2, and Map Protocol.
Du Jun, the co-founder of ABCDE Capital and Huobi, said that he will bring 50 million US dollars to deeply participate in the construction of the Bitcoin ecosystem, and Bitcoin Layer 2 is the preferred track.

300,000 to 3 million: The legend of a veteran in the cryptocurrency circle, from career confusion to wealth tycoon!
Welcome to Chenxi web3 vision
Recently, ETF has been approved, and everyone is joking that they are US stock traders, not the stinky currency speculators they used to be. Today, let’s talk about the name of a big V, the impression of outsiders, and the title of him from the outside world.
It’s a long story.
Was troubled by this problem about 6-7 years ago. Through personal practice, he understood the truth of the problem.
For many years, he has never had a formal name, that is, he has no so-called professional respect from the outside world, and he cannot provide professional convenience to everyone around him, which has been troubled by this.

With Rollup at the center, is the importance of Ethereum protocol upgrades gradually diminishing?
As Ethereum gradually shifts to a Rollup-centric development roadmap, the importance of its protocol changes is gradually decreasing. This article delves into the reasons for this shift and its potential impact on the ecosystem. By analyzing the changing priorities of Ethereum protocol developers, the author reveals that as Rollup matures, the direct impact of protocol-level changes on users will decrease. The article also quotes the views of Aya Miyaguchi, executive director of the Ethereum Foundation, emphasizing the risks and necessity of reducing the roles of protocols and foundations. At the same time, this article points out that the core building blocks of future finance are being built outside the protocol, and Rollup and other innovative technologies will gradually surpass the importance of Ethereum upgrades in the ecosystem.

My account was attacked by missiles over the weekend.
Is everyone okay?
I think the price drop this time has little to do with the Iranian incident.
It may just be an excuse.
After all, Bitcoin has been rising for seven consecutive months, and the halving is coming.
If it rises too much, there will naturally be adjustments.
In the future, the US interest rate cuts and elections are still there,
so don't worry too much.
You should seize the opportunity of falling before and after the halving.
Now it seems that the altcoins have been cleaned up more severely,
which is a good opportunity to pick up cheap chips.

Bybit CEO Ben Zhou has expressed caution regarding a potential $ETH rollback. When asked about it, he stated that he's unsure if it's a decision for one person to make, suggesting instead that it should be a voting process to determine what the community wants.
Zhou's stance is that Bybit will try all available means to recover the stolen funds, including a bounty program, working with law enforcement, and collaborating with the Ethereum Foundation to explore possible solutions. However, he doesn't seem to be actively advocating for a rollback.
It's worth noting that the Ethereum community has rolled back the blockchain before, in response to the 2016 DAO hack. However, this time around, the situation is different, and the community is divided on the issue. Some, like Samson Mow, are insisting on a rollback, while others argue that it's not feasible or desirable.

My thoughts on Ethereum and Rollup
I am very dissatisfied with those who only look at the current state of Ethereum and think that Ethereum should prioritize scaling L1 (first layer solutions). The entire Ethereum ecosystem is in a stage of rapid development, and the view that only scaling L1 is ridiculous.
What happens if we choose to extend L1?
The current L1 expansion capability is insufficient: the transaction processing speed (TPS) on Ethereum L1 may be only 50-100, which is far from meeting the demand.
Rollup teams will look for other options: Current Rollups can use Ethereum as an implementation of data availability (DA). If Ethereum only scales L1, these teams may turn to other alternatives.

Today, Vitalik published a new article titled "Possible Future of Ethereum Protocol, Part 2: Rise", which explores the key goals of the future development of the Ethereum protocol:
1. Achieve the ability of the first layer (L1) and the second layer (L2) to process more than 100,000 transactions per second;
2. Maintain the decentralization and robustness of L1;
3. Ensure that some L2 inherits the core characteristics of Ethereum, such as trustlessness, openness, and censorship resistance;
4. Improve interoperability between L2s, making Ethereum more like a unified ecosystem rather than 34 independent blockchains.
The article points out that the current priority is to improve the roadmap centered on rollup technology, solve related challenges, and continue to ensure the robustness and decentralization of Ethereum L1.
