Overview

Unichain at a glance.

Unichain launched in 2025 as Uniswap Labs' purpose-built Layer 2, part of the OP Superchain alongside Base, Optimism, and other OP Stack chains. It is designed to concentrate DeFi liquidity in a chain governed by UNI token holders, with MEV reduction and fast block times as key design goals.

How it works

How Unichain works.

Unichain uses the OP Stack optimistic rollup architecture: transactions are executed on Unichain and batches are posted to Ethereum for settlement. The fraud proof window allows challengers to dispute invalid state transitions. Unichain runs with a one-second block time and has introduced a Flashblock mechanism that provides 200ms pre-confirmation signals to reduce MEV exposure for users.

Consensus: OP Stack Optimistic Rollup

Unichain uses the OP Stack optimistic rollup architecture: transactions are executed on Unichain and batches are posted to Ethereum for settlement. The fraud proof window allows challengers to dispute invalid state transitions. Unichain runs with a one-second block time and has introduced a Flashblock mechanism that provides 200ms pre-confirmation signals to reduce MEV exposure for users.

OP Superchain

Unichain is part of the OP Superchain, a network of OP Stack chains that share bridging standards, security, and eventually a shared sequencer. This means assets can move between Unichain, Base, Optimism, and other Superchain members more easily than between arbitrary L2s.

Flashblocks

Unichain introduces sub-block pre-confirmation signals called Flashblocks, which give users a 200ms signal before the full block is finalized. This reduces the window in which MEV searchers can front-run transactions.

UNI governance

UNI token holders govern Unichain alongside the Uniswap protocol itself. Revenue from sequencer fees can flow to UNI governance, connecting the chain's economics to the broader Uniswap ecosystem.

DeFi liquidity focus

Unichain is designed to be the primary liquidity destination for Uniswap v4 pools. Concentrating liquidity on one chain improves capital efficiency and reduces the fragmentation across multiple networks.

Ecosystem & usage

What Unichain is used for.

Unichain's ecosystem is anchored by Uniswap v4 as the primary AMM, with DeFi protocols, MEV tooling, and OP Superchain-compatible bridges building around it. As a new chain, the ecosystem was growing rapidly through early 2025.

DefiLlama

Uniswap v4 trading

Unichain is the primary home for Uniswap v4 pools, offering low-cost swaps with the full hook system available for customized liquidity strategies.

DeFi protocol deployment

Lending markets, yield protocols, and other DeFi primitives deploy on Unichain to tap into the concentrated liquidity and Uniswap user base.

MEV-sensitive applications

The Flashblock pre-confirmation system makes Unichain better suited than standard L2s for applications where front-running protection matters.

Cross-chain liquidity via Superchain

Being part of the OP Superchain means liquidity on Unichain can be accessed from Base, Optimism, and other Superchain members using shared bridging standards.

FAQ

Common questions.

What is the OP Superchain?
The OP Superchain is a collection of OP Stack-based L2 chains, including Optimism, Base, and Unichain, that share security standards, bridging infrastructure, and are working toward a shared sequencer. Chains in the Superchain can interoperate more easily than arbitrary L2s.
How does Unichain relate to Uniswap?
Unichain is built by Uniswap Labs, the team behind the Uniswap protocol. It is designed to be the primary deployment chain for Uniswap v4 and is governed by UNI token holders. Sequencer revenue can flow back to UNI governance.
What are Flashblocks?
Flashblocks are pre-confirmation signals emitted by the Unichain sequencer approximately every 200ms, before the full one-second block is finalized. They give users and applications early confirmation that a transaction will be included, reducing the front-running window.
Does Unichain have its own token?
Unichain uses ETH for gas fees. Governance of the chain is handled by UNI, the existing Uniswap governance token. There is no separate Unichain token.
Can I hold assets on Unichain in the Zypto App?
Not yet. ETH isn't in the Zypto App at the moment. You can hold it in any self-custodial wallet, and you can ask us to add Unichain using the "Request Unichain" button above.
