Trump’s recent victory has sparked a DeFi renaissance, positioning Ethereum, which holds 63% of global DeFi TVL, to capitalize on this momentum. Ethereum may have found the catalyst it has long awaited, putting it in an ideal position to benefit from the regime change. Since the U.S. presidential results were announced, the Ethereum ecosystem has consistently outperformed expectations.

However, Ethereum’s rollup-centric roadmap, while essential for scalability, presents a significant challenge: fragmentation. The current rollup ecosystem operates in a winner-takes-most environment, dispersing liquidity, mindshare, and users across isolated L2s. To fully harness this renewed interest in DeFi, Ethereum must address these divisive dynamics to create a more unified and accessible network.

Bridging the Divide: Solving Ethereum’s Fragmentation and Liquidity Challenges

Puffer Finance’s innovative solution, UniFi, tackles Ethereum’s fragmentation challenges head-on. We believe Puffer is poised to outperform once the market recognizes it as an innovative new infra solution, and not just another Liquid Restaking Token (LRT).

What was Puffer?

Initially, Puffer was a leading LRT protocol, focused on providing decentralized staking solutions.

What is Puffer now? Puffer has evolved into an Ethereum-centric unification solution.

Puffer has grown from the first native Liquid Restaking Protocol into a comprehensive Ethereum-integrated scaling ecosystem, consisting of three main components that will be explored throughout the article:

1. Decentralized Liquid Restaking Token (LRT)

Puffer’s flagship anti-slashing LRT offers enhanced yields and security, supporting decentralized restaking within Ethereum’s ecosystem.

1. UniFi Based Rollup Stack

A Layer 2 based sequencing solution enabling seamless interoperability across L2<>L2 and L2<>L1 transactions, allowing atomic composability for efficient cross-chain interactions.

1. UniFi Preconf AVS

The industry’s first preconfirmation AVS, delivering near-instant transaction finality for both L1 and L2, significantly enhancing Ethereum’s network speed and dependability.

Puffer Finance’s UniFi based roll-up stack transforms Ethereum’s fragmentation into a positive-sum ecosystem.

Part 1: UniFi based roll-up stack – what is it and how does it work?

What are based roll-ups?

Based rollups are an advanced scaling approach that integrates directly with Ethereum’s shared sequencer, bypassing the need for centralized sequencers (commonly used in other optimistic and zero-knowledge L2s). The concept was first mentioned in March 2023, part of a research post written by Justin Drake, where he defined it as:

“A rollup is said to be based, or L1-sequenced, when its sequencing is driven by the base L1. More concretely, a based rollup is one where the next L1 proposer may, in collaboration with L1 searchers and builders, permissionlessly include the next rollup block as part of the next L1 block.” – Justin Drake

For non-technical individuals, the above doesn’t make any sense. Simply said, based rollups validate transactions directly on the L1 itself, making the most efficient use of Ethereum’s existing mechanisms. Other popular rollup solutions (optimistic & zk) first validate transactions on the L2, then send them to the L1.

Through based sequencing (sequencing with Ethereum validators), you have the following benefits:

• You inherit the liveness and decentralization of the Ethereum network, ensuring reliability without relying on a single point of failure.
• The infrastructure is simpler, as there’s no need to operate a dedicated sequencer.
• Execution is faster thanks to preconfirmations, providing quicker transaction finality (more on this later).
• There’s an economic alignment with the L1, creating new revenue opportunities for existing validators through non-extractive MEV.
• Operational costs are reduced, as the L1 handles transaction sequencing.

The main disadvantage is that the based roll-up forgo MEV income to the L1, limiting their revenue to base transaction fees.

Based Rollups > Optimistic Rollups

tl’dr:

By streamlining the transaction sequencing processes on the base layer, it becomes possible to lower costs, enhance speed, and preserve the security and decentralization inherent in the Ethereum network.

UniFi is a based roll-up to Ethereum, allowing the creation of app chains through their stack.

They address Ethereum’s liquidity fragmentation by enabling synchronous composability. Transactions on UniFi can interact directly with other based rollups, eliminating the need for bridges and creating a unified liquidity and app layer. Developers can launch their own app-chains with ease, capturing transaction fees and leveraging shared liquidity.

They aim to bring atomic composability to Ethereum – redefining what’s possible on-chain. Through atomic composability, UniFi will allow smooth, integrated interactions between Layer 1 and Layer 2 within one Ethereum block. Picture a user or protocol depositing assets into UniFi from L1, performing complex actions like swaps or yield farming, and then withdrawing back to L1 — all within a single 12-second Ethereum block. This is not only fast but also represents a significant advancement in blockchain interoperability.

Instead of working against the L1, Puffer works with the L1 and extends its capabilities in an integrated manner.

How does it work?

Inspired by this collaborative research with Justin Drake, Puffer UniFi uses TEEs for its procer stack. To achieve real time proving Puffer aims to use TEEs as teaining wheels. Real time proving enables better interoperability. Once ZK provers get fast enough the prover can be evolved from trusted hhardware to Zero Knowledge.

Puffer’s architecture explained

Architecture overview – Puffer’s UniFi Preconf AVS provides L2 Execution confirmations to users. Users interacting with UniFi can enjoy the sub-second transactions. In UniFi general purpose rollup native yield tokens can be used as gas token.

The consensus, data availability, and settlement layers are all components of the base Layer 1, which is Ethereum in this case. The roll-up, on the other hand, is responsible solely for the execution layer.

This is what makes the Puffer app-chain special.

Why should you care?

Puffer is utilizing based roll-ups to create its own app-chain, allowing EVM protocols to integrate seamlessly. This presents an opportunity for everyone in the ecosystem, from individual validators to large-scale dApps, to participate in and gain from a faster, more efficient, and more decentralized Ethereum. Ethereum has been fragmented for far too long and it’s time to change that.

Ecosystem overview:

The growth will occur in phases:

In Phase 1, they will introduce based roll-ups to users and developers. Protocols that are not yet comfortable on running their own app-chain will have the ability to deploy directly on UniFi.

In Phase 2, the UniFi SDK will be launched to enable any dApp developer to spin up an app-chain in a streamlined way.

Part 2: UniFi Preconf AVS

UniFi offers near-instant execution confirmations through preconfs. It’s more than just an increase in speed — it’s a completely new approach to Ethereum scalability. Preconfs are a solution that solves Ethereum’s fragmentation issues and offers blazing-fast confirmations.

How?

As rapid transaction finality is often limited by Ethereum’s 12-second block times, pre-confirmations (preconf) become essential for user experience. To address this, Puffer has developed a proprietary preconf AVS that provides near-instant assurances (~100ms) that transactions will be included in the next block, elevating both the speed and reliability of the based rollup ecosystem.

How does it work?

There are two types of preconfirmations (preconfs): Execution and Inclusion. Both can be utilized to provide users with faster confirmations on L1 or L2s. Execution preconfs have the advantage of offering a final, guaranteed commitment to the user, including confirmation of the transaction state upon execution. For instance, they can confirm the price at which a trade was executed and providing better user experience.

Implementing L1 execution preconfs is challenging; however, L2 execution preconfs address this issue effectively. Puffer UniFi AVS leverages this capability to deliver an enhanced UX.

Pre-confirmations require robust guarantees. Since a preconf represents a commitment by the proposer (validator or delegated proposer), failing to honor it should result in penalties, such as slashing. Restaking protocol such as EigenLayer plays a key role in providing slashing security for preconfs. Notably, Puffer UniFi Preconf AVS is the first AVS of its kind to operate on EigenLayer.

UniFi as a catalyst for Ethereum’s next chapter: unification

UniFi’s synchronous composability is game-changing. Cross-rollup interactions occur as if they’re on a unified chain, eliminating the need for L2 bridges (nobody likes to bridge), reducing costs, and mitigating security risks associated with moving assets. UniFi’s approach unifies liquidity and allows developers and users to seamlessly interact across chains, driving liquidity and improving user experience on Ethereum like never before.

For developers, UniFi presents a unique opportunity to scale their applications within a unified, low-friction environment. By eliminating centralized sequencing, UniFi drastically reduces operational costs and allows developers to focus on their product without worrying about the complexities of managing isolated L2s. UniFi’s setup makes launching a based rollup nearly as simple as deploying a smart contract, significantly lowering entry barriers for developers and encouraging innovation.

Revenue Unlocked: How Puffer’s Based Rollups and Preconfs Drive Value in Ethereum’s Ecosystem

All revenue streams will generate treasury rewards, governed by the $PUFFER token.

Puffer’s upgraded revenue model (remember, not just an LRT) leverages based rollups and preconfirmations to create sustainable value across the Ethereum ecosystem. With based rollups, Puffer generates sequencing fees by enabling Ethereum validators to manage transaction ordering. This approach supports seamless interoperability between Ethereum’s L1 and L2, as well as among L2s, creating unified liquidity and composability. Through sequencing fees integrated within Ethereum’s validator network, Puffer captures transaction-based revenue while reinforcing Ethereum’s native economic value.

Users can offer preconfirmation tips to prioritize their transactions, generating an additional revenue stream for Puffer alongside transaction inclusion fees. These fees and tips are routed back into Puffer’s ecosystem, enriching its native tokens, pufETH and unifiETH, and providing yield to token holders.

As Amir, contributor Puffer, explains:

“If every user pays an extra fee for these pre-confirmations to ensure a faster and more reliable transaction on Ethereum, the AVS is tied to every transaction a user makes on Ethereum. This creates a very powerful revenue-generating AVS that can sustainably provide organic yield without needing another token or secondary mechanism.”

Introducing vePuffer

A key aspect that makes a protocol achieve sustainable long-term price action is tokenomics. A great protocol must have well thought out token models, with a focus on providing value towards long-term holders. At Mechanism Capital, we have a core focus on tokenomic designs. We support teams that innovate and maximize their token’s value capture.

Puffer Finance is launching vePuffer as a tokenomics update. The aim is to trickle down value to holders and align incentives throughout the ecosystem. They are doing so by introducing the following:

Decentralized Governance: vePUFFER lets the community vote on PUFFER point allocations, aligning with Puffer’s decentralization goals.

Tradeable Points: Season 2’s ERC20 PUFFER points allow for trading, enabling early profits or additional purchases, adding flexibility and speculative potential.

Flexible Strategy: Tradable points give users control to hold, sell, or buy based on personal strategy and market sentiment, enhancing risk management.

Bribery Market: Protocols can offer incentives to vePUFFER holders to boost votes for their pools, increasing APRs and liquidity.

Competitive Protocols: The bribery system lets protocols attract votes to improve APR, driving engagement and creating aligned incentives.

Community-Driven Rewards: The vePUFFER model fosters governance, speculation, and diverse strategies, empowering users to shape ecosystem incentives.

Why Puffer’s UniFi Stands Out: Revolutionizing Ethereum’s Rollup Landscape

With the launch of UniFi, Puffer has created an opportunity for Ethereum to transition from a fragmented rollup environment into a cohesive, positive-sum landscape that brings developers, users, and liquidity together in unprecedented ways. The result? A stronger, more resilient Ethereum that can meet the needs of billions.
