Getting Started

1. Prerequisites

   • Foundry development environment

   • Ethereum wallet and Base Sepolia ETH

   • Familiarity with Solidity and blockchain concepts

2. Installation

   git clone https://github.com/capsign/protocol.git capsign
   cd capsign
   forge install

3. Integration

   We recommend using our Node.js SDK for interacting with CapSign contracts:

   npm install @capsign/sdk

   // Example SDK usage
   const CapSign = require("@capsign/sdk");
   
   // Initialize connection to CapSign contracts
   const capsign = new CapSign.Client({
     network: "base-sepolia",
     privateKey: process.env.PRIVATE_KEY,
   });
   
   // Interact with tokenized assets
   const myAssets = await capsign.assets.getAll();

API Documentation

Comprehensive API documentation is available at docs.capsign.com/api-reference.

Note: CapSign currently only supports the Base Sepolia testnet. Mainnet support coming soon.

Architecture

Capsign is built on a trustless, self-custodial architecture:

• 100% On-Chain Operations: All asset management and transactions occur on-chain

• Self-Custodial Design: Users maintain complete control of their assets

• Decentralized ID Attestation: The only component with an off-chain element, providing secure identity verification

• Smart Contract Layer: Secure and audited contracts for asset tokenization and management
