Angstrom

Angstrom is a DEX built on top of Uniswap V4 whose core goal is to re-internalize arbitrage value that MEV bots would otherwise extract, returning it to liquidity providers. It uses App-Specific Sequencing: on Ethereum mainnet a staked off-chain validator network runs arbitrage and batch auctions, matching at a uniform clearing price so sandwich attacks are structurally impossible; on L2s the auction moves on-chain and captures MEV through protocol taxes. Protected liquidity pools use a custom Hook that locks at the start of each block, completing Angstrom's sequenced batch settlement before opening to the public.

In the ecosystem, Angstrom's division of labor with regular AMMs is that it does not fight arbitrage via the pool itself but uses sequencing rules to keep value with LPs, suiting market makers sensitive to slippage and front-running; its L1 version stays composable with Uniswap V4 pools, still serving as a standard pool after settlement. This design therefore makes L1 transaction ordering depend on that staked off-chain validator network rather than Ethereum proposers, with misbehavior triggering slashing, so censorship resistance leans considerably on the honesty assumption of that external sequencing layer.
