Ethereum UniversalLoginSDK is composed of smart contracts, a js lib, and a relayer that help build applications using ERC #725, #735, #1077 and #1078.

This is a work in progress. Expect breaking changes. The code has not been audited and therefore can not be considered secure. Planned functionality for first release include:

• Creating and managing identities
• Multi-factor authentication
• Universal login
• Ether less transactions via relayer

This repository is organised as monorepo.

• Contracts - all contracts used in this project
• Relayer - allows to interact with blockchain
• SDK - easy way to communicate with relayer by http protocol
• Example - example app, which shows how to use SDK

To start hacking around go to tutorial. To just see example in action follow the next section.

To install dependencies and build projects run following commands from the main project directory:

yarn && yarn build

To run example:
