TrustLink Project Status

✅ Completed

Core Implementation

• ✅ Complete Soroban smart contract structure
• ✅ Admin and issuer management system
• ✅ Attestation creation with deterministic IDs
• ✅ Attestation revocation functionality
• ✅ Expiration handling

• ✅ Event emission for indexers

Code Organization

• ✅ Modular architecture (lib, types, storage, validation, events)
• ✅ Comprehensive error handling
• ✅ Storage patterns using Soroban SDK
• ✅ TTL management for persistent storage

Testing

• ✅ Unit tests for all major functions
• ✅ Integration test example (cross-contract verification)
• ✅ Test coverage for:
  • Initialization
  • Issuer management
  • Attestation lifecycle
  • Expiration logic
  • Authorization checks
  • Pagination

Documentation

• ✅ Comprehensive README with usage examples
• ✅ Deployment guide (DEPLOYMENT.md)
• ✅ Inline Rust documentation
• ✅ Integration example showing cross-contract usage
• ✅ Makefile with common commands
• ✅ Build script (build.ps1)

Project Files

• ✅ Cargo.toml with proper dependencies
• ✅ .gitignore for Rust/Soroban projects
• ✅ rust-toolchain.toml for consistent builds

⚠️ Known Issues

Compilation Status

The project structure is complete, but there may be minor compilation issues related to:

1. ID Generation: The generate_id function uses env.to_bytes() and env.from_bytes() which may need adjustment based on the exact Soroban SDK version
2. Build Time: Initial compilation takes significant time due to Soroban dependencies

Recommended Fixes Before Push

1. Test the ID Generation:

   // Current implementation in types.rs may need adjustment
   // Consider using a simpler approach like:
   pub fn generate_id(...) -> String {
       let hash = env.crypto().sha256(&env.to_bytes(&(issuer, subject, claim_type, timestamp)));
       // Convert hash to string representation
   }

2. Run Full Test Suite:

   cargo test

3. Verify Build:

   cargo build --target wasm32-unknown-unknown --release

📋 Pre-Push Checklist

Before pushing to main, ensure:

• Code compiles without errors
• All tests pass
• Documentation is accurate
• No sensitive information in code
• .gitignore is properly configured
• README reflects current state

🚀 Next Steps

Immediate (Before Push)

1. Fix any remaining compilation errors
2. Run full test suite
3. Verify WASM build succeeds
4. Review all documentation

Post-Push

1. Set up CI/CD pipeline
2. Deploy to Stellar testnet
3. Perform integration testing
4. Security audit
5. Add more comprehensive tests
6. Create example dApp integration

📝 Notes

• The contract uses Soroban SDK v21.0.0
• Storage uses persistent storage with 30-day TTL
• Events are emitted for all state changes
• IDs are deterministically generated from attestation data
• The contract is designed to be queried by other contracts

🤝 Contributing

When contributing:

1. Follow Rust best practices
