Quartz CosmWasm Packages

This repository contains a collection of packages designed to facilitate the development of CosmWasm smart contracts for Quartz apps.

Packages

1. quartz-cw

The quartz-cw package offers a high-level framework for building attestation-aware smart contracts by wrapping CosmWasm messages in TEE attestations (e.g. DCAP).

  • Defines Attested<M, A> wrapper for a message and its attestation
  • Supports a MockAttestation type for development ease
  • Implements session management for secure communication between contract and enclave The quartz-cw package handles actual DCAP verification within smart contracts by calling the standalone quartz-dcap-verifier and tcbinfo contracts.

2. quartz-dcap-verifier

Your personal DCAP detective! This package is a standalone smart contract for verifying DCAP attestations that can be called by other contracts.

  • Thin wrapper for standalone smart contract around the functionality provided in the quartz-tee-ra package
  • Provides query and execute entry points for attestation checks

3. quartz-tee-ra

This quartz-tee-ra handles Intel SGX remote attestation for both EPID and DCAP protocols.

  • Verifies EPID and DCAP attestations
  • Provides core types and structures for SGX quotes
  • Implements cryptographic verification of attestation reports

4. tcbinfo

The tcbinfo package manages and verifies TCB information crucial for maintaining enclave security.

  • Stores and retrieves TCB information
  • Verifies TCB signatures and certificates
  • Provides a CosmWasm contract for TCB management

5. wasmd-client

The wasmd-client package offers a Rust client interface for interacting with Wasmd nodes.

  • Defines traits for querying and executing CosmWasm contracts
  • Provides utilities for deploying and interacting with contracts

Examples

Check out the integration_tests modules in each package for usage examples and best practices!
