Optimize Soroban RPC Connection Pool

[gabito1451]

Context

Stellar RPC nodes can throttle excessive connections.

Problem

The backend creates new connection instances too frequently.

Suggested Execution

• Implement a singleton pattern for the 'Stellar.Server' instance.
• Add circuit breaker and fallback nodes.

Acceptance Criteria

• Stable RPC connectivity.
• Graceful degradation if primary node fails.

Hi! I can implement the Soroban RPC connection pool optimization.

What I'll deliver:

• Singleton pattern for Stellar.Server instance with lazy initialization
• Connection pooling with keepAlive: true and configurable max sockets
• Circuit breaker with automatic fallback to backup RPC nodes
• Thread-safe implementation for concurrent requests

Tech: TypeScript/Node.js with the Stellar SDK.

Happy to discuss scope and pricing — DM me or comment here.
