GnoSDK MVP

[moul]

This issue defines the V1 or MVP version of the future GnoSDK (#873). This version is essential for test4 and the launch, while the broader GnoSDK issue focuses on making GnoSDK reusable for new TM2+GnoVM chains, which isn't a current priority.

Goals

• Simplicity and Reliability: Prioritize simplicity and reliability, even if performance is not highly optimized.
• Clean API/Usage: Ensure the API and usage are clean, especially for smart contracts. Avoid using the recently introduced std.Emit event system for data exchanges, as emitted events are not as explicit and simple to test as returned typed values.

Suggested Implementation

• Develop helpers to call a contract's functions from the gnoland app.
• Implement proper error management and data marshalling.
• Include options such as "read-only" (execute without saving realm changes).

Expected Usages

• r/sys/names Namespace support for package paths #1107
• r/sys/valset feat(PoC,gov): initial sys/validators and gov/dao contracts #1945
• r/sys/vals feat: add /r/sys/validators #2130
• r/sys/teams feat: add r/sys/teams #2184
• r/sys/eula
• r/sys/vars
