ConsenSys is a blockchain software company founded in 2014 by Joseph Lubin, one of Ethereum's co-creators. The company builds Ethereum-native infrastructure and applications for the web3 ecosystem, with a team of over 700 technologists, researchers, and builders working entirely remotely. Its engineers and designers have contributed to every major Ethereum upgrade from the genesis block through The Merge and beyond.
Its product portfolio includes several widely used tools in the web3 space. MetaMask is a self-custody cryptocurrency wallet available on mobile and browser. Infura provides developer infrastructure for accessing Ethereum and other networks. Linea is a layer-2 network built on Ethereum. Across these products, ConsenSys covers the infrastructure, wallet, and scaling layers of the Ethereum ecosystem.
Technical work at ConsenSys spans Ethereum protocol development, developer tooling, institutional-grade staking infrastructure, digital identity, and open-source software. The company also engages in policy advocacy on blockchain and web3 issues in Washington and Brussels.
ConsenSys operates as a remote-first, Ethereum-native organisation with a stated mission to decentralise finance and make digital assets and identity accessible. Its open-source principles and long-term focus on Ethereum distinguish its engineering culture from that of more commercially oriented technology firms.
