SC-47: Dynamic NFT Avatar Minting with On-Chain Chess Win-Loss Metadata Updates

[chinweobtagaz]

Problem Statement

Players want dynamic NFT avatars on Stellar that evolve visually as they achieve higher chess ratings and tournament milestones.

Proposed Solution

1. Develop an SEP-compatible NFT contract on Soroban with mutable on-chain state.
2. Expose authorized update_record(token_id, wins, losses, elo, title) function invoked by authorized game oracle.
3. Dynamic SVG/JSON metadata URI returning updated artwork tiers based on rating bracket.

Acceptance Criteria

• Soroban contract written with strict access control.
• Gas-optimized state storage.
• Test cases verifying rating upgrades and unauthorized update rejection.

@chinweobtagaz This issue could not be added to the Stellar Wave Program because the per-repo points budget would be exceeded (24950 / 25000 points already used). The label has been automatically removed.

The budget resets at the end of each Wave. You can review the remaining budget for your repos on the Orgs & Repos page.
