ConsenSys is one of the most influential companies in the Ethereum ecosystem, building a suite of products that millions of people use to interact with blockchain technology. Founded in 2014 by Joseph Lubin, one of Ethereum’s co-founders, the company has been a driving force behind Ethereum adoption since the network’s earliest days.
MetaMask, ConsenSys’s most widely known product, is the dominant browser wallet for interacting with Ethereum and EVM-compatible chains. With over 30 million monthly active users at its peak, MetaMask serves as the primary gateway for most people entering the world of DeFi, NFTs, and decentralized applications. The wallet generates revenue through built-in swap functionality that charges a small fee on trades.
Infura provides the backend infrastructure that keeps much of the Ethereum ecosystem running. The service offers API access to Ethereum and other networks, handling billions of requests daily. Many of the most popular dApps and wallets rely on Infura for their blockchain connectivity — a concentration of infrastructure that has sparked debate about decentralization.
ConsenSys also built Linea, a zkEVM Layer 2 network that uses zero-knowledge proofs to scale Ethereum transactions. Linea launched in 2023 and has been growing its ecosystem of applications and users steadily.
The company is headquartered in Brooklyn, New York, with offices worldwide. After starting as a sprawling venture studio that incubated dozens of projects, ConsenSys restructured to focus on its core products. The company raised a $450 million Series D in 2022 at a $7 billion valuation. Despite market downturns and multiple rounds of layoffs, ConsenSys’s products remain deeply embedded in the Ethereum ecosystem’s daily operations.
