group_treasury

Group Treasury integrates Safe Smart Accounts (multi-signature wallets) as treasuries for Drupal Groups, enabling DAOs and communities to manage shared funds with blockchain security and Drupal workflows.

Features

Basic Functionality:

Links a Safe Smart Account (multi-signature wallet) to any Drupal Group as its treasury
Adds a "Treasury" tab to Groups displaying wallet balance, signers, threshold requirements, and transaction history
Enables Group members to propose treasury transactions (ETH transfers, contract calls) requiring multi-sig approval
Tracks signature collection progress within Drupal while cryptographic signing happens via MetaMask
Automatically proposes Safe signer changes when Group roles change (admin added/removed requires existing signer approval)

Unique Features:

Combines Drupal's Group permission system with blockchain multi-sig security
Optional treasury creation wizard requiring Group creators to deploy a Safe during group setup
Treasury signer relationships appear on user's Safe account list with quick actions
Fine-grained Group-level permissions: view treasury, propose transactions, sign transactions, execute transactions, manage treasury

Use Cases:

DAOs requiring community-managed treasuries with multi-signature security
Organizations needing shared fund management with role-based access control
Open-source projects accepting cryptocurrency donations with transparent governance
Collaborative groups requiring financial accountability and audit trails

Post-Installation

Enable the relation plugin: Navigate to /admin/group/types/manage/{type}/content and install the "Group Safe Account (Treasury)" relation plugin for each Group Type that needs treasury support.
Configure permissions: Go to /admin/group/types/manage/{type}/permissions to assign treasury permissions to appropriate Group roles.
Optional - Treasury Wizard: Edit the Group Type and enable "Group creator must complete treasury deployment" under Creator Wizard settings.
Create Treasury: Navigate to any Group → Treasury tab → "Create Treasury" to deploy a new Safe Smart Account as the group treasury.

The module adds a "Treasury" local task tab to all Groups with the Safe Smart Accounts relation plugin enabled.
