📣 Puffer UniFi V2 testnet is now live! 🐡
The UniFi V2 testnet is officially live, and we’re inviting builders to explore the stack and join the next phase of Ethereum-native infrastructure.
With the advancement of based rollup technology, UniFi offers a practical path forward to address Ethereum’s fragmentation and foster ecosystem growth.
UniFi-OP enables Ethereum builders and users to avoid choosing a “winning” L2 or giving up revenue. Based sequencing keeps rollups, appchains, and general-purpose chains fully composable with Ethereum. Thanks to UniFi AVS, rollup owners can now share priority fees and MEV with validators.
This upgrade was made possible in collaboration with
@gattacahq,
@eigencloud,
@AutomataNetwork, and
@ethereum.
⚒️ What Builders Get
• Governance‑optional rollups 🗳️
• Custom fee markets (subsidize, burn, or share)
• KYC‑gated or fully permissionless chains
💆 What Users Feel
• Sub‑10 ms confirmations ⚡
• One‑click exits to L1 (no 7‑day wait)
• Seamless L1 interaction—AMMs, CLOBs, RWAs “just work”
📈 Economic Win‑Win
Based sequencing ≠ giving up MEV and Priority fees.
Rollup owners, gateways, and L1 proposers share MEV & congestion fees through @puffer_unifiAVS. Alignment without sacrifices.
🧩Pragmatic Composability
How composable is UniFi V2?
• L2 → L1 withdrawal supported
• EIP‑7702 smart‑wallet standard baked in
• Atomic withdrawals in the same block (no more 7 day wait)
🛡️Trust‑Minimized, Real‑Time Proving
Real time proving is a must have to achieve composability and security that a rollup needs. We came up with a trust minimized pragmatic approach with TEEs for the first phase.
In collaboration with
@automatanetwork we now have:
• Multi‑TEE provers (Intel TDX AMD SEV) attest each block in less than 1s.
• Hardware diversity = reduced trust assumptions.
🏎️UniFi AVS (Gateway Registry)
For Preconfimrations (preconfs), we take advantage of delegated proposing to gateways to bring the speed. This service requires shared security.
🏗️Built on
@eigencloud:
• Validators opt in and delegate proposer rights.
• They earn extra yield for serving preconfs.
• Restaking validators solve the cold‑start problem.
💻 Preconf Phases
• Centralized gateways at launch.
• Progressive onboarding → many independent gateways for decentralization.
• Proposer‑delegated based sequencing (speed).
🗺️Roadmap
• ✅ Hybrid Based‑OP stack with TEE proving & fast gateways
• 🔜 ZK proving
• 🔜 Universal Registry Contract (URC) by ****@fabric_ethereum for slashing
• 🔜 Commit boost
@commit_boost integration
• 🔜 Native L1 ↔ L2 ↔ L2 calls All upgrades are backward‑compatible and shipped incrementally.
⚔️Security Model at a Glance
• Restaked ETH → slashable backing
• Multi‑vendor TEEs → hardware redundancy
• ZK fallback → cryptographic safety net No single point of failure.
🎯Metrics That Matter
The KPI moves from TVL to transaction volume & speed. High‑frequency order‑flow is real revenue—and UniFi lets dApps capture it instead of donating it to someone else’s sequencer.
🧑💻Code & Collaboration
UniFi V2 extends the open work by
@GattacaHQ on Gattaca‑OP. Dive into the repos and contribute.
📚TL;DR
• Pragmatic composability with atomic withdrawals from the L2.
• Trust‑minimized, real‑time proving
• UniFi AVS bootstrapped by EigenLayer
• Based rollups that share income
🪖Builders: stop choosing between UX, composability, and revenue. DM us or visit
