@Luchistack has applied to work on this issue as part of the Stellar Wave Program's 6th wave.

I have reviewed this issue and its acceptance criteria carefully. The requirements are clear and well-scoped (large complexity). I have hands-on experience with NestJS and can implement this following the patterns and conventions already in the codebase. I will deliver complete, tested code that satisfies every acceptance criterion without requiring follow-up corrections. I can start immediately and am happy to discuss approach details with the maintainer beforehand.
