Hydro Snowflake - Marketplace Coupons

GitHub package.json version GitHub Build Status Coverage Status Language grade: JavaScript Total alerts Known Vulnerabilities


Snowflake is an ERC-1484 Provider that provides on-/off-chain identity management. For more details, see the whitepaper.

This project is essentially a chain of smart contracts built on top of the Hydro Snowflake protocol, aiming to provide a marketplace platform for sellers to launch their own stores and sell to users. Coupons are also featured, allowing users to use globally defined coupons guaranteed to expire within a certain time period, or assigning coupons per Snowflake EIN, manageable via multiple addresses.

The marketplace itself is a Snowflake Resolver contract, which interacts with a Snowflake Via contract to handle the transaction (and thus coupon discount) logic.

This project is still under development, and dramatic changes will likely occur quickly. The full scope of the prospective completed project can be viewed here
