Difficulty

Task

Implement pool ownership logic for ChainMove vehicle investment pools in the Soroban contract workspace.

Expected behavior

The contract should support:

• creating a vehicle pool
• setting total pool units or shares
• recording investor contribution
• calculating investor share percentage
• preventing oversubscription
• reading investor position

Acceptance criteria

• Pool cannot exceed total available units.
• Investor position is calculated consistently.
• Duplicate investments are handled safely.
• Contract stores enough data for later indexing.
• Unit tests cover success and failure paths.

Test requirement

Add tests for successful pool creation, successful investment, oversubscription rejection, duplicate investor update, and investor share calculation.

Evidence required

• Screenshot of cargo test passing.
• Screenshot showing contract function output or test logs.

Commands

cargo test
npm run lint
npm run build
