ConsenSys is a global blockchain infrastructure and software company founded by Ethereum co-founder Joseph Lubin that builds developer tools, enterprise applications, and scaling solutions powered by Ethereum. Its flagship products—MetaMask (self-custodial wallet securing $60B in assets) and Infura (node infrastructure serving millions of transactions)—serve as critical infrastructure for the Web3 ecosystem. The company also develops Linea (Layer 2 scaling), Quorum (enterprise blockchain platform acquired from JPMorgan), and provides smart contract auditing and staking services to enterprises and developers.

Digital Asset builds Daml, a smart contract language and distributed ledger platform that enables developers to code multi-party agreements across blockchains, DLTs, and databases. Daml 2.0 includes Canton, a privacy-enabled distributed ledger supporting cross-blockchain atomic transactions. The platform serves financial services, healthcare, and insurance organizations—including 5 of the top 10 stock exchanges—to eliminate reconciliation delays, reduce settlement risk, and enable real-time capital markets infrastructure. The core differentiation is cross-blockchain interoperability: a single transaction can execute an asset transfer on Hyperledger Besu while a payment settles on Hyperledger Fabric.

Stronghold creates virtual payment networks that instantly settle transactions and enable interoperability between legacy banking systems and blockchain-based payment rails. The platform offers card processing, ACH transfers, merchant financing, and checkout services, with the unique ability to bridge traditional and modern payment infrastructure. They specifically serve high-compliance industries like gambling and alcohol that struggle to access financial services, rewarding transaction volume with SHx tokens that offset fees.
