What is Unichain?

Uniswap built their own blockchain to make trading cheaper and protect users from bots that profit off their trades. The key difference: when bots extract value from trades, that money goes back to liquidity providers instead of disappearing to third parties.

Best for: Trading on Uniswap, providing liquidity to pools, any DeFi app that wants faster and fairer trades.

Technical: OP Stack rollup with Flashbots TEE block builder for MEV redistribution and sub-second confirmations.

• Security & Data Availability

  • Stage 1 optimistic rollup with permissionless fault proofs
  • Standard 7-day withdrawal period for optimistic rollups
  • Currently centralized sequencer, decentralized validation network planned
  • TEE-based block building for transparent transaction ordering

• Infra & Execution

  • Built on OP Stack, fully EVM-compatible
  • TEE (Trusted Execution Environment) enables encrypted mempool
  • Priority fee ordering protects against sandwich attacks
  • Working toward 250ms block times (Flashblocks), currently 1 second

• Performance

  • Comparable gas costs to other L2s
  • Block times faster than most L2s at 1 second
  • Significant adoption among DeFi protocols
  • Strong liquidity depth inherited from Uniswap ecosystem

• Use Cases

  • Uniswap trading: Lower costs and better prices due to MEV protection
  • Liquidity provision: Earn from MEV that would normally be extracted
  • DeFi protocols: Euler, Morpho, and others already deployed
  • Fast trading apps: Near-instant confirmation for better UX

• Trade-offs

  • Primarily benefits Uniswap ecosystem participants
  • Requires trust in hardware security (TEE) not just cryptography
  • Another L2 adding to ecosystem fragmentation
  • Still building out decentralization features
