Snapshot
Continue to About ↓- What it does
- Unichain is a DeFi-focused Ethereum Layer 2 (an OP Stack optimistic rollup in the Optimism Superchain) built for fast, low-cost onchain trading and liquidity, with ~200ms Flashblocks preconfirmations and 1-second blocks.
More detail
- It is developer and DeFi infrastructure rather than a consumer app: users interact through wallets, bridges and apps, and builders deploy EVM-compatible contracts.
- Uniswap Labs is the primary technical provider while OP Labs operates the sequencer, and its terms state Uniswap Labs does not operate or control Unichain.
- Best for
- DeFi developers and Uniswap v4 hook builders who need an EVM-equivalent, low-latency chain, and onchain market makers, liquidity providers or stablecoin/payments teams working on DeFi markets.
- Pricing
- There is no subscription or listed price; Unichain is a public network and costs are usage-based.
More detail
- Transactions require gas paid in Unichain ETH, but no official fee schedule or per-transaction cost is published, so exact network fees are undisclosed.
- Uniswap Labs operates the sequencer and its terms
- Main limitation
- People wanting a managed investment product, brokerage, custody or advisory service, and production users who need a published SLA, enterprise support, or reliance on rate-limited public RPC endpoints.

What it helps with
- High latency on many L2s for trading and arbitrage, addressed by 1-second blocks and ~200ms Flashblocks preconfirmations
- MEV value leakage in onchain markets, addressed through lower latency intended to increase arbitrage frequency and reduc
- Fragmented cross-chain liquidity, addressed through native interoperability plans within the Superchain and support for
- High Ethereum L1 transaction costs, addressed by moving execution to a Layer 2
