Today, every chain is an island
Rollups and appchains each run on their own. Moving between them means bridges and long withdrawal waits, so users and liquidity end up split apart.
Building the settlement layer for the agentic economy
Puffer UniFi confirms in 50ms, so AI agents can pay, trade and settle across Ethereum in real time. Sign once, and every transaction is ordered by Ethereum's validators and settled on Ethereum.

From isolated rollups to one Ethereum, in three steps.

Puffer UniFi joins them into one Ethereum
Puffer UniFi chains are ordered by Ethereum's own validators and share one settlement layer. Assets move between them and withdraw to L1 instantly.

Fast enough for agents
With 50ms confirmations, AI agents can act across chains in a single transaction, settled on Ethereum.
Instant withdrawals
Withdraw to Ethereum right away, with no days-long rollup wait.
Fast transactions
Transactions confirm in 50ms, fast enough for people and AI agents alike.
Ethereum security
Blocks are ordered by Ethereum's own validators, not a single company's sequencer.
