Contract Upgrade Demo

This document demonstrates the working contract upgrade system.

Demo Script

A script scripts/demo_upgrade.sh has been created to automate the following steps:

1. Build Version 1 of the contract.
2. Deploy V1 to Testnet.
3. Initialize V1.
4. Verify Version is 1.
5. Modify source code to Version 2 (changing get_version to return 2).
6. Build V2.
7. Upgrade the deployed contract to V2 code.
8. Verify Version is 2.

Execution Log

Below is the output of running the demo script:
