Interoperability with Classic Stellar Assets

[hman38705]

Issue #21:

Developer Goal: Enable the seamless use of existing Stellar Classic assets (like USDC) within the Soroban contract.

Technical Requirements:

1. SAC Integration: Use the soroban_sdk::token::Client to interact with Stellar Asset Contracts (SAC).
2. Trustline Handling: The contract itself should be able to "opt-in" or handle assets without manual trustline management, but developers must ensure the token_address is a valid SAC.
3. Clawback & Freeze: Implement logic to handle cases where the issuer of a Classic asset "Claws back" or "Freezes" the contract's balance. The market should transition to Cancelled if the prize pool is seized.

Verification Checklist:

• Integration test using a "Classic" asset wrapper and verifying successful place_bet and claim_winnings.
• git checkout -b features/issue-Interoperability with Classic Stellar Assets
• Pr Request create your pr against develop branch

Hi @solutions-plug, I would like to implement the Classic Stellar Asset interoperability for PredictIQ. Bridging the gap between the Classic network and Soroban is essential for liquidity, and I have a clear path for the implementation:

SAC Integration: I will utilize soroban_sdk::token::TokenClient to ensure the contract interacts seamlessly with any valid SAC, specifically for processing betting deposits and prize distributions.

Security & Compliance: I'll implement robust handlers for Freeze and Clawback events. If the contract detects that the prize pool balance has been seized or frozen by an issuer, I will implement an automatic transition to the Cancelled state to protect the integrity of the market.

Testing: I will write comprehensive integration tests using the TokenClient in a mock environment to simulate a "Classic" asset wrapper, ensuring that place_bet and claim_winnings function correctly with wrapped USDC or XLM.

Git Workflow: I will follow the requested branch naming convention and target the develop branch for the PR.

I'm ready to start immediately and ensure a secure, interoperable experience for PredictIQ users.
