tKey

lerna code style: prettier npm

tKey is the underlying SDK used to implement Web3Auth Plug n Play. This package can also be used to self host Web3Auth in your own system. tKey stands for Threshold Key, which refers to the management keys & shares generated using threshold cryptography.

The tKey SDK

The tKey SDK manages private keys by generating shares of it using Shamir Secret Sharing. For example, for a 2 out of 3 (2/3) setup, we give the user three shares: ShareA, ShareB, and ShareC.

  • ShareA is stored on the user’s device: Implementation is device and system specific. For example, on mobile devices, the share could be stored in device storage secured via biometrics.
  • ShareB is managed and split across Web3Auth's Auth Network, accessed by an OAuth login provider that a user owns.
  • ShareC is a recovery share: An extra share to be kept by the user, possibly kept on a separate device, downloaded or based on user input with enough entropy (eg. password, security questions, hardware device etc.).

Similar to existing 2FA systems, a user needs to prove ownership of at least 2 out of 3 (2/3) shares, in order to retrieve his private key.

For more information, check out the technical overview. Before integrating you can also check out the example for tKey.

To use the SDK in your application, please refer to our SDK Reference in Web3Auth Documentation

Building the SDK Locally

Requirements

  • This package requires a peer dependency of @babel/runtime
  • Node 14+

Installation

npm run bootstrap
npm run pack:lerna

Bundling

Each sub package is distributed in 4 formats

  • esm build dist/<MODULE_NAME>.esm.js in es6 format
  • commonjs build dist/<MODULE_NAME>.cjs.js in es5 format
  • commonjs build dist/<MODULE_NAME>-bundled.cjs.js in es5 format with problematic packages bundled (benfits non-webpack users)
  • umd build dist/<MODULE_NAME>.umd.min.js in es5 format without polyfilling corejs minified

By default, the appropriate format is used for your specified usecase You can use a different format (if you know what you're doing) by referencing the correct file

The cjs build is not polyfilled with core-js. It is upto the user to polyfill based on the browserlist they target

Directly in Browser

CDN's serve the non-core-js polyfilled version by default. You can use a different

jsdeliver

<script src="https://cdn.jsdelivr.net/npm/<MODULE_NAME>"></script>

unpkg

<script src="https://unpkg.com/<MODULE_NAME>"></script>

Tips for NUXT

This is a plugin that works only on the client side. So please register it as a ssr-free plugin.
