UniFi Testnet: Revolutionizing Ethereum Scaling with Based Rollups
Disclaimer: This announcement is part of a series showcasing the innovations being developed at Puffer. Stay tuned for more updates in the coming weeks.
Today, we’re thrilled to announce the Testnet launch of UniFi, a based rollup to Ethereum that will fundamentally change the entire L2 landscape. UniFi is low-cost, capable of sub-second transactions, and allows asset withdrawal from L2 (UniFi) to L1 (Ethereum) within a minute, which is multitudes faster than any existing rollups.
Best of all, UniFi is economically aligned with Ethereum, meaning that increased usage of UniFi will lead to more revenue captured by Ethereum validators. Start building on UniFi testnet today and stay tuned for the upcoming mainnet launch.
What is UniFi?
UniFi is a based rollup to Ethereum, designed to provide an enhanced experience for both users and developers, while remaining economically aligned to Ethereum. We know that developers are the lifeblood of any L2 ecosystem, and that is why we worked hard to ensure that UniFi is a conducive place for developers to experiment and build from both a product and economic perspective:
- Sub-second Transactions:UniFi is optimized for speed, allowing for near-instant transactions
- Instant Withdrawals from L2 to L1: Unlike other rollups that may require a waiting period, UniFi enables almost instant asset withdrawals from the UniFi (L2) back to Ethereum (L1), enhancing liquidity and user experience.
- Synergy with the LRT Flywheel:Puffer’s successful Liquid Restaking Token (LRT) ecosystem already brings a strong foundation of liquidity and community support. To further enhance UniFi’s ecosystem, we’ll encourage LRT holders to bridge their liquidity into UniFi, providing developers with immediate access to the liquidity needed to power their dApps.
- Preconfirmations for Added Security: UniFi’s preconfirmations offer a strong improvement over traditional soft confirmations by using Ethereum validators instead of centralized sequencers. This ensures near-instant (100ms) confirmation times with enhanced reliability, as validators face penalties for failing to include transactions, delivering both speed and security.
- Seamless Appchain Deployment: With UniFi, developers can deploy appchains effortlessly, benefiting from Ethereum’s security while enjoying scalability and ease of customization — perfect for building efficient, interoperable dApps.
- Season 2 Points Enhancements:As part of Puffer’s Season 2 campaign, our points system will be revamped to encourage active participation within UniFi. This gives builders access to a motivated, engaged community eager to explore and interact with new dApps, creating a vibrant environment for developers and users alike.
So why is Puffer building a Based Rollup?
As Ethereum grew, the need for effective scaling solutions became clear. Layer 2 rollups emerged as a popular answer, but they often relied on centralized sequencers, which introduced trade-offs like fragmented liquidity and lost value for Ethereum’s main network (L1). That’s where UniFi comes in.
UniFi is built on based rollups; meaning UniFi uses Ethereum’s own validators to sequence transactions instead of separate centralized L2 sequencers. This keeps scaling aligned with Ethereum’s principles of security and decentralization while providing additional income opportunities for validators. With based sequencing, the same validators that secure Ethereum’s base layer also support UniFi, creating a mutually beneficial relationship: UniFi gains Ethereum’s security, and validators see new revenue streams.
At Puffer, advancing Ethereum’s decentralization has always been our mission. We began with the Puffer LRT, optimizing validator operations, and now, with UniFi, we’re pushing Ethereum’s scalability forward. UniFi’s ecosystem is further strengthened by our UniFi AVS, providing secure preconfirmations to enhance transaction reliability and user experience. By reinforcing Ethereum’s decentralized foundation, we’re not just scaling Ethereum — we’re building a solution that remains true to its core values.
What’s ahead for UniFi: Atomic Composability
While UniFi in its current state already offers a groundbreaking solution for Ethereum scaling, we’re pushing the boundaries even further. Our research team is working tirelessly to bring atomic composability to UniFi — a feature that will redefine what’s possible on the blockchain.
With atomic composability, UniFi will enable seamless, integrated interactions between L1 and L2 within a single Ethereum block. Imagine a user or protocol depositing funds into UniFi from L1, executing complex operations like swaps or yield farming, and withdrawing back to L1 — all in the space of a single 12-second Ethereum block. This isn’t just fast; it’s a whole new level of blockchain interoperability.
The potential impact is vast. DApps on UniFi will gain direct access to Ethereum L1’s massive liquidity and user base, allowing for near-instant cross-layer arbitrage. Complex, multi-step DeFi operations that previously faced layer boundaries can now flow effortlessly, expanding the range of applications and user experiences on the blockchain.
We expect to have atomic composability in UniFi’s mainnet launch, so look forward to that.
Join the UniFi Testnet Today!
The UniFi Testnet offers a unique opportunity to experience the benefits of sub-second transactions, instant withdrawals, and Ethereum-aligned decentralization firsthand. As we approach our mainnet launch, your feedback and participation will be invaluable in shaping the evolution of UniFi.
Our Testnet participation will be in 2 different phases:
- UniFi Testnet (Builders exclusive)
- UniFi Testnet (Public)
Specifically, in this first phase of testnet, we are looking for DApp developers to start building on UniFi, and also experiment new forms with DApps which is made possible by the atomic composability in UniFi. Reach out to our team via this form if you are interested to build on UniFi: https://forms.gle/oiGKetUnHr2pLDzZ8
Join us on this journey to set new standards in Ethereum scalability — a future that’s faster, more interoperable, and deeply committed to Ethereum’s decentralized vision. Together, let’s unlock the true potential of blockchain technology with UniFi.
