+# Dependency Audit Report
+
+**Last Updated**: 2025-01-27
+**Purpose**: Analysis of dependencies across all projects
+
+---
+
+## Overview
+
+This document provides an analysis of dependencies across all projects in the workspace, identifying common dependencies, version inconsistencies, and opportunities for consolidation.
+
+---
+
+## Analysis Methodology
+
+1. Scan all `package.json` files in the workspace
+2. Extract production and development dependencies
+3. Count usage frequency
+4. Identify version inconsistencies
+5. Recommend consolidation opportunities
+
+**Note**: Run `scripts/deps-analyze.sh` to generate an updated analysis report.
+
+---
+
+## Common Dependencies
+
+### Most Frequently Used (Production)
+
+Based on initial analysis, these dependencies appear frequently:
+
+#### TypeScript/JavaScript Core
+- **typescript**: Used across TypeScript projects
+- **zod**: Schema validation (used in 10+ projects)
+- **dotenv**: Environment configuration (used in 15+ projects)
+- **date-fns**: Date handling (used in 5+ projects)
+
+#### Framework & Runtime
+- **react**: Frontend projects
+- **nextjs**: Next.js applications
+- **express**: Backend services
+- **fastify**: Backend services
+
+#### Blockchain/Solidity
+- **ethers** / **viem**: Ethereum libraries
+- **@openzeppelin/contracts**: Smart contract libraries
+- **foundry**: Solidity development (dev dependency)
+
+#### Database
+- **@prisma/client**: Database ORM
+- **postgresql**: Database client
+
+#### Utilities
+- **winston**: Logging
+- **jsonwebtoken**: Authentication
+- **bcryptjs**: Password hashing
+- **uuid**: UUID generation
+
+### Most Frequently Used (Development)
+
+#### Build & Tooling
+- **typescript**: TypeScript compiler
+- **eslint**: Linting
+- **prettier**: Code formatting
+- **@typescript-eslint/***: TypeScript ESLint plugins
+
+#### Testing
+- **vitest**: Testing framework (newer projects)
+- **jest**: Testing framework (older projects)
+- **@testing-library/react**: React testing utilities
+
+#### Build Tools
+- **vite**: Build tool
+- **tsx**: TypeScript execution
+- **tsc**: TypeScript compiler
+
+---
+
+## Version Consolidation Opportunities
+
+### TypeScript
+- **Current Versions**: Multiple versions (5.3.3, 5.5.4, etc.)
+- **Recommendation**: Standardize on latest stable (5.5.4+)
+- **Impact**: High - affects all TypeScript projects
+
+### Zod
+- **Current Versions**: Multiple versions (3.22.4, 3.23.8, etc.)
+- **Recommendation**: Standardize on latest (3.23.8+)
+- **Impact**: Medium - shared validation library
+
+### ESLint
+- **Current Versions**: Multiple versions (8.56.0, 8.57.0, 9.17.0)
+- **Recommendation**: Migrate to ESLint 9.x across all projects
+- **Impact**: High - affects code quality tooling
+
+### Prettier
+- **Current Versions**: Multiple versions (3.1.1, 3.2.0, 3.3.3)
+- **Recommendation**: Standardize on latest (3.3.3+)
+- **Impact**: Medium - code formatting
+

+
+## Shared Package Candidates
+
+### High Priority (Used in 5+ Projects)
+
+1. **@workspace/shared-types**
+   - Common TypeScript types
+   - Used in: dbis_core, the_order, Sankofa, etc.
+
+2. **@workspace/shared-utils**
+   - Common utilities (date formatting, validation, etc.)
+   - Used in: Multiple projects
+
+3. **@workspace/shared-config**
+   - Shared configuration schemas
+   - Used in: All projects with configuration
+
+4. **@workspace/shared-constants**
+   - Shared constants and enums
+   - Used in: DBIS projects, DeFi projects
+
+### Medium Priority (Used in 3-4 Projects)
+
+1. **@workspace/api-client**
+   - Common API client utilities
+   - Used in: Frontend projects, API consumers
+
+2. **@workspace/validation**
+   - Zod schemas and validators
+   - Used in: Multiple backend services
+
+---
+
+## Dependency Security
+
+### Security Scanning
+- Run `pnpm audit` or `npm audit` in each project
+- Use Dependabot for automated updates
+- Review and update vulnerable dependencies regularly
+
+### High-Risk Dependencies
+- Review dependencies with known vulnerabilities
+- Prioritize updates for security-critical packages
+- Document security update process
+
+---
+
+## Recommendations
+
+### Immediate Actions
+
+1. **Hoist Common DevDependencies**
+   - typescript
+   - eslint
+   - prettier
+   - @typescript-eslint/*
+   - vitest/jest
+
+2. **Create Shared Packages**
+   - Start with @workspace/shared-types
+   - Create @workspace/shared-utils
+   - Extract common validation schemas
+
+3. **Version Consolidation**
+   - Standardize TypeScript version
+   - Standardize Zod version
+   - Standardize ESLint/Prettier versions
+
+### Long-Term Actions
+
+1. **Dependency Audit Process**
+   - Quarterly dependency reviews
+   - Automated security scanning
+   - Version update workflow
+
+2. **Shared Package Strategy**
+   - Extract shared code gradually
+   - Document shared package APIs
+   - Version shared packages independently
+
+---
+
+## Tools for Analysis
+
+### Automated Tools
+- **npm-check-updates**: Check for outdated packages
+- **depcheck**: Find unused dependencies
+- **npm-audit**: Security vulnerability scanning
+- **pnpm-why**: Understand why dependencies are installed
+
+### Manual Review
+- Review package.json files regularly
+- Track dependency updates
+- Document breaking changes
+
