Espresso Systems is the lead developer of Espresso, a global confirmation layer designed to enhance cross-chain composability by providing fast and reliable transaction confirmations. Espresso confirmations help reduce finality risk and prevent issues like sequencer equivocation, making it easier for applications to operate across multiple chains. The network is currently in its Mainnet 0 release and supports various functionalities, including fast confirmations, decentralized sequencing, and low-cost data availability.
At Espresso Systems, we work with leading teams developing chains, rollups, and applications including Offchain Labs, Polygon, Cartesi, RARI Chain, and beyond—all united in our mission to build an open Web3 experience without silos for all users.
