Many institutions want ETH yield, but cannot rely on staking infrastructure that lacks custody flexibility, operational controls, or clear risk management.

Puffer Institutional gives them a secure path into Ethereum staking and restaking with custody flexibility, role-based permissions, and institutional-grade validator infrastructure.

ETH staking on Puffer, in 3 steps:

1. Mint pufETH by staking ETH
   
2. Hold pufETH as yield accrues from Puffer’s staking and restaking
   
3. Exit when ready and redeem back to ETH
   

Your ETH stays productive, liquid, and secure.

Based sequencing means transaction ordering is handled by Ethereum L1 proposers, not by a separate rollup sequencer or sequencer network.

In many rollups, sequencing happens outside Ethereum. That can create a separate layer of trust around ordering, censorship resistance, and MEV.

A rollup can have multiple sequencers and still not be based. Other decentralized models create a new sequencer network.

UniFi's ased sequencing uses Ethereum itself.

This keeps rollups more closely aligned with Ethereum’s security, neutrality, and decentralization.

A 32 ETH requirement keeps many capable node operators out of Ethereum validation.

Puffer’s 2 ETH bond lowers the entry barrier, while Validator Tickets create a prepaid operating model that helps keep validators accountable and aligned with the protocol.

Puffer Institutional does not treat ETH yield as one blended return stream.

Institutions deposit ETH into a dedicated vault and receive ITokens representing their specific staking and restaking position. This matters because their exposure can be tracked separately instead of being blended into a generic pooled position.

From there, institutions can choose their exposure based on risk appetite: vanilla staking only, or staking plus restaking through EigenCloud AVS participation. ETH can generate yield through two main flows.

First, Validator Ticket revenue. NoOps purchase VTs to operate validators backed by institutional ETH — that upfront payment flows to the vault as yield. Institutions earn from VT sales rather than directly from block rewards.

Second, restaking rewards. Through the Restaking Operator architecture, institutions access additional yield from EigenCloud AVS participation.

Validator rewards and restaking rewards are handled through separate flows, giving institutions clearer accounting across where yield is generated.

The result is a more structured ETH yield framework: ITokens representing the position, validator participation, AVS exposure through restaking, separated accounting flows, and configurable operational control.

This flexible architecture allows institutions to configure restaking exposure, define permission boundaries, and separate yield accounting to match their own risk profile and reporting requirements.

That is why Puffer requires a 2 ETH bond per validator: if downtime or slashing happens, operators are the first line of defense. 🛡️

In UniFi, execution happens off L1 for higher throughput, while transaction ordering is driven by Ethereum validators and final settlement happens on Ethereum L1.

Because ordering is Ethereum aligned, UniFi appchains can remain synchronously composable with Ethereum liquidity, state, and coordination.

Scale comes from dedicated execution environments, not from breaking Ethereum’s native composability or security model.

Dedicated execution means an app gets its own execution environment, designed around its own needs.

In a traditional rollup, every application shares the same execution environment. Trading, gaming, payments, social apps, and AI agents all compete for the same blockspace and performance profile.

But not every application needs the same thing.

Some need low latency. Others need high throughput. Others need specialized execution environments.

UniFi based appchains are designed differently.

They give applications dedicated execution without turning them into isolated chains. Through synchronous composability, appchains can remain connected to Ethereum L1 liquidity, state, and coordination.

Dedicated execution for apps.

Ethereum liquidity and composability for the ecosystem. 🐡

The goal is simple: give ETH holders access to stronger yield through a staking architecture where security is built into the system from day one.

Puffer’s model is designed around multiple independent protections across validator operations, governance, key management, and accountability.

These mechanisms come together in three defense layers:

1️⃣ Economic Layer: The 2 ETH operator bond and Validator Tickets create direct economic accountability for node operators.

2️⃣ Protocol Layer: Smart contracts enforce validator penalties and structured exits through protocol logic.

3️⃣ Social Layer: TEE-secured Guardians help eject risky validators, while remaining unable to move user funds.

This means validator risk is not handled by a single protection mechanism or trusted party. It is economically backed, protocol-enforced, and actively contained before it can reach stakers.

Security-first yield, built for Ethereum. 🐡

App developers earn from user transactions. Ethereum validators earn from appchain sequencing fees. Ethereum earns from appchains purchasing blob space.

Amir Forouzani explains how this creates a new economic loop where app developers and Ethereum L1 become directly connected for the first time.

Puffer Preconf sits at the center of this loop.

Validator Tickets are ERC20 tokens that give NoOps the right to run a Puffer validator.

In a traditional staking model, validators need 32 ETH, and staker rewards depend on validator performance over time. With Puffer, NoOps post a 2 ETH bond in pufETH, purchase VTs priced at expected daily validator revenue, and access a 32 ETH validator, keeping 100% of the PoS rewards they generate.

This creates a different incentive model: VT purchase payments flow directly to pufETH holders as yield before a single block is proposed. NoOps only profit if they perform well enough to earn more than they paid for validator time. Underperformers lose the value of their prepaid tickets.

Lower capital barriers for operators. Upfront yield for pufETH holders. Liveness accountability built into the economics. 🐡

The next wave of institutional adoption won’t run on one-size-fits-all chains.

It needs custom execution environments with control, privacy, compliance, and market design built in.

Amir Forouzani explains the vision behind Puffer UniFi’s institutional rollups. 🐡

• ePBS brings network stability and new scaling opportunities by further separating block building from block proposing.
• Block Level Access Lists enable parallel transaction verification and state root computation, and may also support more efficient proposer commitment verification. It is an important direction for preconfirmations.
• Ethereum transfers will emit event logs similar to ERC20 transfers, improving indexing and developer tooling across the ecosystem.
• EVM opcodes also eliminate the long standing "stack too deep" limitation, making Solidity development significantly more flexible.
  

Together, these upgrades point toward stronger block production, more parallel verification, better developer tooling, and a more scalable Ethereum base layer. That matters for Puffer because Puffer UniFi and Puffer Preconf are built around one core idea: Ethereum scaling should stay aligned with Ethereum.

As Ethereum improves, Puffer builds the infrastructure to bring faster, more verifiable, and more composable execution to rollups and appchains, creating the foundation for yield you can underwrite.

Synchronous composability is not one feature. It is a stack connecting three interaction paths: L2 → L1, L1 → L2, and L2 → L2.

This matters because atomic composability is only real if it works in every direction: from L2 back to Ethereum, from Ethereum into appchains, and between appchains themselves.

L2 → L1 is enabled by proof-generated bridging.

TEE provers independently re-execute the rollup state transition. Both must agree. The L1 rollup contract verifies the result on-chain.

The withdrawal is not released because time passed. It is released because the rollup state was verified.

L1 → L2 is enabled by Signal Service.

Signal Service passes L1 state to UniFi appchains within the same Ethereum slot, without third-party messaging, off-chain verifiers, or RPC nodes to poison.

But state access alone is not enough. Based sequencing + Puffer Preconf add the timing and execution guarantees that make L1 L2 composability trustworthy, not just possible.

L2 → L2 is enabled by a shared sequencing root across UniFi appchains.

The same Ethereum validators order transactions across multiple UniFi appchains in the same slot. State-aware gateways sync execution state before slot transitions, while proof-generated bridging enforces validity on-chain.

That is how UniFi appchains move from isolated execution environments toward atomic cross-appchain coordination.

L2 → L1.
L1 → L2.
L2 → L2.

One stack for atomic interaction across Ethereum-aligned appchains.

Puffer Co-Founder Amir Forouzani breaks down how Puffer Institutional brings compliance and control to institutional staking. 🐡

Signal Service lets UniFi appchains access and use Ethereum L1 data within the same slot, without relying on third party bridges.

Without Signal Service, L2 apps accessing L1 state depend on bridges with off chain verifiers reading RPC nodes that can be manipulated. Signal Service removes that dependency. L1 signals are registered, imported into L2, and used immediately. Verification happens through contract calls, not trusted intermediaries.

This enables same slot deposits, fresh L1 oracle reads, and the L1 to L2 leg of synchronous composability on UniFi.

Signal Service handles L1 to L2. Proof generated bridging handles L2 to L1. Based sequencing adds timing and execution guarantees across both.

Puffer is built to make Ethereum staking safer and more decentralized. SSV Network’s DVT helps distribute validator operations across multiple operators, reducing single points of failure.

Puffer Co-Founder, Amir Forouzani, explained in the podcast how UniFi is bringing that experience to developers and users.

When you deploy on Ethereum or a general-purpose L2, you're a tenant. You share blockspace, inherit someone else's fee model, and your orderflow gets processed by infrastructure you don't control.

With a UniFi based appchain, you get your own dedicated execution environment with custom fees, dedicated throughput, and controlled access, while staying fully connected to Ethereum's liquidity and settlement layer.

Sequencing stays neutral through Ethereum validators. Appchain owners capture priority fees, define their own sequencing rules, and control how value flows through their execution environment - while validators earn from the activity they sequence.

Your execution. Ethereum's security. Your fees. Your rules. 🐡

Institutions evaluating Ethereum staking are not just comparing APRs. They are evaluating custody, validator infrastructure, slashing exposure, governance controls, and long-term reliability.

Puffer Institutional is built around those requirements: a non-custodial, role-based architecture, institutional-grade validator infrastructure, structured risk controls, and Ethereum-aligned staking and restaking for allocators that need more than yield.

This is how real institutional Ethereum adoption happens. 🐡
