It provides node clients, staking infrastructure, and security auditing for financial institutions and enterprises. Consensys is a blockchain infrastructure company that builds protocol level software and institutional tools for the Ethereum ecosystem. It provides node clients, staking infrastructure, smart contract security audits, and validator signing services. Its offerings serve financial institutions, enterprises, and infrastructure operators building on Ethereum and Ethereum compatible networks. The company works with banks, asset managers, custodians, exchanges, and other financial market infrastructure providers to deploy blockchain technology aligned with their regulatory and operational requirements. It supports institutions across network design, integration, and ongoing operation, offering advisory services, platform engineering, and managed operations for permissioned and public Ethereum based deployments. Its portfolio includes Besu, an open source Ethereum client used in public and private network deployments, Teku, a client built for institutional staking, and Web3Signer, a signing service for validators and custodians. Consensys Diligence provides smart contract auditing and security tooling, while Consensys Staking offers infrastructure for institutional validators. These products are used by banks, asset managers, central banks, custodians, and exchanges building tokenized and onchain financial infrastructure, and the company recently reorganized to concentrate on this institutional and protocol infrastructure focus, separating from its consumer facing business. - Type: Company - Sector: Infrastructure - Status: Active - Founded: 2014-11-01 - Profile: https://thegrid.id/profiles/consensys ## Products - [Consensys Diligence](https://thegrid.id/profiles/consensys): Consensys Diligence is a smart contract audit service that combines automated analysis engines with manual security review to detect vulnerabilities before deployment.

It provides full protocol compatibility for enterprise-grade Ethereum deployments. (Node Software, Live) - [Teku](https://thegrid.id/profiles/consensys): Teku is an Ethereum consensus client that supports proof-of-stake validation for institutional staking operations. It provides infrastructure for network participation and validator operations on Ethereum. (Node Software, Live) - [ConsenSys Staking](https://thegrid.id/profiles/consensys): ConsenSys Staking is a managed staking service that lets enterprises and institutions stake ETH without operating their own validator infrastructure. It handles validator selection, operations, and reward distribution while keeping staked tokens under the client's control. The service offers an API for integrating staking into applications alongside a dedicated staking dashboard. (Staking & Validation Services, Live, Main Product) - [Web3Signer](https://thegrid.id/profiles/consensys): Web3Signer is a remote signing service that manages private keys and signs transactions and blocks on behalf of Ethereum validators and node operators. It separates key management from node infrastructure, allowing operators to sign consensus and transaction data without exposing keys directly on validator hardware. The tool is used by staking and validation operations requiring secure, centralized key management. (Node Software, Live) - [Lineth](https://thegrid.id/profiles/consensys): Lineth is an open-source zero-knowledge rollup stack that developers use to build scalable Ethereum-based networks. It provides the underlying framework and tooling for launching custom rollups rather than being a single deployed chain itself. The project is maintained under the Linux Foundation Decentralized Trust umbrella alongside other Consensys-originated infrastructure tools.
