Espresso is a crypto project focused on blockchain infrastructure rather than consumer payments. Its network is built to help rollups and other chains coordinate transaction ordering, confirmations, and shared state in a more consistent way, with the goal of improving how separate onchain systems connect and operate together.
The project is especially tied to the modular blockchain world. Instead of acting as a standalone app, Espresso is meant to serve as a shared base layer that other chains can use for core network functions, which gives it a role in the backend architecture of Ethereum-aligned scaling systems.
The token, ESP, is used in Espresso’s proof-of-stake system. Validators and delegators stake ESP to help secure the network, and rewards are distributed to participating validators and their delegators based on block production and stake participation.
Overall, Espresso is best understood as a foundational crypto infrastructure project aimed at helping rollups and related chains function more smoothly at scale. Its value proposition is centered on providing shared network coordination, while ESP supports participation in the security and staking mechanics of that system.
