#637 Add CircuitBreaker pattern for Stellar network calls

[vic-Gray]

Area: reliability · Effort: M\n\nWhat: Wrap Stellar Horizon calls with a circuit breaker that opens after repeated failures.\n\nWhy: Without it, a Stellar outage causes cascading failures across the app.\n\nHints:\n- backend/src/stellar/services/stellar.service.ts\n- Use opossum or a similar Node.js circuit breaker library

I would like to work on this issue because adding a circuit breaker will make the app more reliable when Stellar Horizon calls fail. It can help prevent repeated failures from affecting the whole system during an outage or temporary network problem.

I have experience working with backend services, API calls, and error-handling logic. I can review the existing Stellar service, wrap the Horizon calls with a circuit breaker using a suitable Node.js approach, and make sure failures, retries, and recovery are handled cleanly without breaking the current flow.

Hey! I'd like to take on this issue. Plan:

• Wrap Horizon calls in stellar.service.ts with a circuit breaker using opossum
• Configure open threshold, timeout, and fallback behavior to prevent cascading failures during Stellar outages

Can I get this assigned?

I'll wrap the Stellar Horizon calls in stellar.service.ts with a circuit breaker using opossum, configure appropriate failure thresholds and timeout values, and make sure the breaker state is observable (open/closed/half-open) for easier debugging during outages.
Can I get this assigned to me?
