attest.so

A Unified Trust Framework for blockchain-based attestation infrastructure

Overview

attest.so provides infrastructure for builders to create "Reputation Authorities" onchain with verifiable and comprehensive identity proofs. The project supports multiple blockchain platforms, enabling a unified approach to attestations.

Key Components

1. Smart Contracts

The repository contains smart contract implementations for multiple blockchain platforms:

• Solana: Using Anchor framework for attestation services, schema registry, and resolver functionality
• Starknet: Using Cairo language implementation
• Stellar: Using Soroban smart contract platform
• Aptos: Using Move language

Core attestation functionality includes:

• Creating and registering schemas
• Issuing attestations
• Revoking attestations
• Managing attestation authorities
• Optional fee collection through a levy system

2. SDK (Software Development Kit)

A TypeScript SDK that provides methods for:

• Connecting to blockchain platforms
• Creating and registering schemas
• Attestation creation, verification and management
• Attestation querying and status verification

3. CLI (Command Line Interface)

A command-line tool to interact with the protocol, allowing users to:

• Create and publish schemas
• Fetch attestation data
• Manage attestations without direct SDK usage

4. Documentation Website

A Next.js-based documentation site with guides and references.

Project Structure

The repository follows a monorepo structure using pnpm workspaces:

• /apps: Front-end applications, including the documentation website
• /contracts: Smart contract implementations for different blockchains
• /packages: SDK, CLI, and shared utilities
• /examples: Example applications showing usage patterns

See NAMING.md for details about the naming conventions and directory structure standards used in this project.
