Paradigm-led Sorella Labs: Flashbots' Rival or Ally?
Sorella Labs developed the Brontes and Angstrom tools to mitigate application-layer MEV.

Sorella Labs yesterday announced a $7.5 million seed round led by Paradigm, with participation from Uniswap Ventures, Bankless Ventures, Robot Ventures, and Nascent. Sorella Labs is a crypto startup focused on addressing MEV (Maximal Extractable Value) issues within the Ethereum ecosystem.
Overview of Core Tools
Sorella Labs is developing two core tools:
Brontes: An open-source blockchain analytics tool that processes Ethereum block data, classifies transaction behaviors, and identifies MEV through pattern matching and analysis. It can be thought of as an open-source Etherscan with custom block analysis capabilities. Brontes went live today and is now publicly available.
Specifically, Brontes classifies transactions based on their behavior—including transaction initiators, recipients, amounts, and gas fees—and transforms raw Ethereum blockchain data into structured, easily analyzable formats, significantly simplifying the data preprocessing pipeline. Additionally, Brontes integrates off-chain data such as centralized exchange prices, metadata, and peer-to-peer data to enable more comprehensive and accurate analysis. To accommodate diverse user needs, Brontes offers a modular framework allowing users to create and apply customized analytical methods. This makes Brontes a highly extensible tool ideal for complex blockchain data analysis.
Angstrom: A tool designed to reduce common arbitrage activities on decentralized exchanges, planned for release as a hook for Uniswap V4. Uniswap V4 introduces new features including hooks, a singleton design (where all liquidity pools are managed by a single contract), and support for native ETH pairs, expected to launch in the second half of this year. In Uniswap V4, hooks are customizable smart contracts attached to liquidity pools that allow developers to execute custom logic at specific points in the pool’s lifecycle. Angstrom will function as a hook, running two auction mechanisms per block via Sorella’s off-chain network.
-
First Auction: Determines which transaction gets priority execution within a block. Normally, transaction ordering is determined by gas price and submission time, making it vulnerable to front-running—where attackers pay higher gas fees to execute trades just before large orders, profiting from resulting price movements. Angstrom's first auction introduces fair bidding: even if a front-runner attempts to insert a transaction, they must compete through the auction to gain priority. Thus, attackers can no longer guarantee early execution simply by increasing gas fees or submitting faster.
-
Second Auction: A batch auction where all orders are executed at a single price point, preventing sharp price fluctuations caused by large individual trades. This mitigates sandwich attacks and general arbitrage, further enhancing protection.
Sorella Labs vs Flashbots
Flashbots and Sorella Labs share similar goals but differ in implementation approaches and target audiences, creating a complementary relationship.
Flashbots focuses on solving MEV issues at the Ethereum protocol layer, aiming to improve fairness and transparency in MEV extraction by optimizing operations for miners and validators. Flashbots has introduced a suite of tools like MEV-Boost, establishing a standardized MEV auction system that reduces malicious competition across the network and ensures miners and validators extract MEV in a fairer environment. These tools not only reduce unfair competition among validators but also mitigate the negative impacts of MEV. Flashbots’ primary objective is to enhance the overall security and transparency of the Ethereum network while creating a more equitable competitive landscape for participants.
In contrast, Sorella Labs concentrates on application-layer MEV mitigation, building tools like Brontes and Angstrom that operate directly at the DeFi application level. Their goal is to reduce losses for liquidity providers and improve trade execution quality for end users. Sorella Labs aims to protect DeFi users’ interests by enhancing transaction fairness and efficiency at the application layer.
