Web3 Auth

This module allows connecting and authenticating in Drupal 10, with a web3 wallet and Metamask.

Features

User management can be disabled in settings if you only want to connect wallet in front-end, without altering the user creation and login core system.

The following default chains dictionnary is set :
- Ethereum Mainnet
- Goerli Testnet

You can specify the required chain id and define your own chains dictionnary.

A custom block includes buttons to connect, switch network, add network, and provides info about web3 connection.

You can configure the module at /admin/config/web3_auth/settings

Similar projects

This is in fact a complete rewrite of the web3 module, as it needed major changes to work with Drupal 10:

• no jQuery (as no more present in D10)
• no 3rd paty web3 libs which requires an external account/API key
• other improvements on wallet chnages and more...
