Angstrom Overview

Angstrom Banner

Angstrom is a new kind of DEX built on top of Uniswap V4 that internalizes its MEV through application-level sequencing. By enforcing its own transaction ordering, Angstrom redirects value that would normally be extracted by MEV bots and validators back to the actual participants—liquidity providers and swappers.

Chain-Specific Designs​

Angstrom ships in two versions tuned for where they run, each pursuing the same goal—internalizing MEV for LPs—while adapting to that chain’s constraints.

  • Ethereum Mainnet (L1): Running the auction on-chain would be prohibitively expensive and faces builder censorship risks, so Angstrom uses an off-chain validator network to execute the auction and enforce sequencing. → L1 System Overview
  • Ethereum Layer-2 (L2): On sequencer-led L2s with guaranteed priority ordering and cheaper gas, we move the auction on-chain and capture MEV via protocol-level taxes. This keeps the architecture lean and integration-friendly. → L2 Overview

Why use Angstrom?​

For Liquidity Providers​

  • LPs Recoup Arbitrage: Traditional AMMs leak immense value to arbitrageurs (Loss-Versus-Rebalancing). On Ethereum mainnet Angstrom’s application-level sequencer runs an off-chain arbitrage auction every block. On L2s the same economics are enforced via an on-chain arbitrage auction with MEV taxes. Both designs internalize MEV value leakage and redistributes the proceeds straight to LPs. For the first time, LPs retain their value when prices move instead of losing to arbitrage.

  • Maximize fees: Now unburdened by what has been—namely, relentless arbitrage— LPs can deploy highly concentrated, dynamically managed positions, achieving superior capital efficiency and dramatically increasing fee revenue, driving tighter spreads and deeper liquidity.

For Traders​

  • MEV-Free Execution (L1): All trades in a block clear at a uniform price via our batch auction, making sandwich attacks impossible.
  • Get The Best Of On & Off-Chain Liquidity (L1): Angstrom’s batch auction merges off-chain limit orders and AMM liquidity into a single, unified market—delivering best in class execution and market depth.
  • Gasless Swaps (L1): Trade without ever needing ETH in your wallet—Angstrom handles it for you.
  • Zero Priority Fees (L1): Unless the block is full, you never need to pay priority fees.
  • 50% Lower Gas Costs (L1): Angstrom’s lean contract design and batch execution slash gas costs by half compared to Uniswap V3/V4.
  • Lower Trading Fees (L1 & L2): Shielded from toxic arbitrage, LPs can sustainably reduce their trading fees.

For Token Issuers​

  • Reduce subsidy reliance: With LPs shielded from arbitrage and earning genuine trading fees, protocols no longer need to deploy exorbitant token incentives to attract liquidity.
  • MEV as Revenue for Token Creators (L2): Pool creators on L2 can charge a portion of the MEV tax, generating a new revenue stream that scales with trading activity.
