sv3.network

The Web3-native evolution of SignVault.io — A decentralized document, signature, and compliance platform that turns documents into on-chain Real-World Assets (RWAs).

🌐 Vision

sv3.network is building a fully decentralized, blockchain-native compliance and document management network where:

• Documents as On-Chain RWAs: Every document is minted as an NFT with immutable metadata
• E-Signatures on Chain: Signatures are recorded as on-chain events, timestamped and verifiable
• Organizations & Teams On-Chain: Smart contract-based team management with role-based access
• Audit & Compliance Layer: Immutable event logs for every document action
• Cross-Chain Interoperability: Works across any EVM-compatible chain

🏗️ Architecture

Smart Contracts

• DocumentRWA.sol - Core contract for document management and NFT minting
• Organization.sol - Organization management and membership with role-based access
• UserProfile.sol - User identity and profile management
• Message.sol - Messaging system between users
• NFT.sol - Base NFT contract for document tokens

Technology Stack

• Frontend: Next.js 15, React 19, TypeScript, Tailwind CSS, Radix UI
• Web3: Viem, Wagmi, Web3Modal, Sign-In with Ethereum (SIWE)
• Blockchain: Solidity, Foundry, Hardhat
• Database: PostgreSQL with Kysely ORM
• Storage: IPFS for document storage

Development Setup

1. Clone and install dependencies:

git clone https://github.com/SignVault/sv3.network.git
cd sv3.network
bun install

2. Set up environment variables:

# Copy environment files
cp packages/app/.env.example packages/app/.env
cp packages/foundry/.env.example packages/foundry/.env
cp packages/hardhat/.env.example packages/hardhat/.env

3. Start development servers:

# Start the frontend app
bun run app:dev

# Or start all services
bun run dev

Smart Contract Development

Using Foundry (Recommended):

cd packages/foundry
forge install
forge test
./deploy.sh sepolia

Using Hardhat:

cd packages/hardhat
bun install
bun test
bun deploy
