Hydro enables new and existing private systems to seamlessly integrate and leverage the immutable and transparent dynamics of a public blockchain, to enhance application and document security, identity management, and transactions.

Created by Hydrogen, a fintech platform for developers and enterprises, Project Hydro is an open source, community-driven initiative built on top of Ethereum. Those protocols are currently H2O in its various forms:

Raindrop is a multi-factor authentication protocol that secures user accounts and databases.

Snowflake is a decentralized identity protocol that helps individuals craft their digital identities and enables projects to easily and securely access this data. Snowflake acts as a passport for identification information, with the HYDRO token as a gateway fee, allowing dApps into the network and streamlining user interactions.

Tide comprises smart contracts that make it simple to create real-world decentralized applications to facilitate identity-linked payment functions across P2P, point of sale, e-commerce, credit, and traditional payment systems. The HYDRO token is used for all subscriptions, remittances, interest, invoicing and more.

Ice is a file-management system that enables documents and data to be stored, stamped, transacted and encrypted on the blockchain. HYDRO tokens maintain ecosystem integrity and are used to pay for services.

Hail is identity-linked security tokenization.

A number of products and smart contracts have already been developed within Hydro, giving users access to everything from peer-to-peer payments to secure file storage.

Hydro Pay is a peer-to-peer payment app leveraging the Hydro ERC-1484 identity standard. Gas fees are removed to better facilitate small payments between users.
