Puffer Upgrades UniFi Preconf AVS to Deliver Sub-10ms Execution With Restaked Security
Puffer Finance, a protocol launchpad specialising in Ethereum‑aligned rollups, has released an upgraded version of its Preconfirmation AVS (Preconf AVS) functionality. The new version enables execution guarantees with sub‑10 millisecond latency for OP‑based rollups, underpinned by over 3 million ETH in restaked security.
Puffer Finance supports scalable protocol deployment by combining unified restaking, rollup‑based infrastructure, and modular composability. With this upgrade, its UniFi Preconf AVS delivers a production‑ready mechanism for Ethereum‑native transactions that are executed within sub‑10 ms guarantees at a fixed price, with slashing collateral and rollup revenue-sharing incentives supporting economic security.
By design, rollups inherit Ethereum's approximate 12‑second block times, which limits performance for latency‑sensitive applications. Puffer's upgraded Preconf AVS addresses this by offering execution guarantees that ensure exact transaction outcomes at the time of transaction, rather than relying on later settlement prices.
The enforcement mechanism leverages EigenLayer's restaked ETH model. Validators and gateway operators back their sequencing commitments with slashing risk to mitigate potential liveness failures, toxic MEV exposure, or protocol-safety faults. The deployment currently secures in excess of 3 million ETH in restaked assets, providing significant economic depth for all UniFi‑integrated rollups.
Key Features of the Upgrade
Delegated Gateway Rights: Validators delegate block proposer responsibilities to specialized gateways focused on sequencing.
Lookahead Scheduling: Gateways receive advance visibility into upcoming L1 slots for precise coordination.
Refund Mechanisms: Users are refunded if Preconf execution fails.
Three‑Phase Rollout:
Phase 1: Early gateway access with validator delegation, no slashing—missed events forfeit rewards. First implementation supports sub‑100 ms confirmations via the Gattaca frags‑based gateway.
Phase 2: Expanded gateway participation and implementation of lookahead scheduling. Incentive structures modular and more decentralized.
Phase 3: Introduction of slashing for liveness or MEV risks (ranging from ~1 ETH to 1,000 ETH), integration with Ethereum's Universal Registry Contract, post-slash challenge/fraud‑proof periods, and mechanisms to redistribute or reclaim slashed collateral.
Additionally, a rewards distribution system has been introduced. Rather than routing all gains from preconfirmations to L1 proposers, a dynamic revenue-sharing model allocates incentives among validators, gateway operators, and rollup operators. Slashed funds are either refunded to affected users or retained within the Preconf rewards pool, aligning rollup operator interests with Ethereum's decentralization goals without fragmenting liquidity.
