Backend & Infrastructure

Infrastructure Stack

• Cloud Provider: AWS

• Core Components:

  • EC2: Node.js orchestration scripts (deployment + monitoring)

  • RDS PostgreSQL: Off-chain index data and transaction logs

  • Quarkus (Java): Internal monitoring & risk‑screening engine for OLTA index funds

  • CloudWatch: Log aggregation and alerts

  • Secrets Manager: Secure storage of API credentials (e.g. Alchemy, Chainlink)

System Functions

• Fetches live oracle prices

• Calculates Net Asset Value (NAV) of each index

• Monitors wallet interactions (mint/redeem)

• Logs and exposes data for frontend and analytics

• Enforces slippage limits and trade thresholds

Security & Reliability

• Environment variables secured via AWS Secrets Manager

• Separate execution roles for core logic and observability

• Safe-controlled access to production-like resources

• Basic failover/restart scripts in place

Future Enhancements

• Index performance analytics (drawdown, volatility metrics)

• Monitoring dashboard (Grafana-based)

• On-chain + off-chain data reconciliation

• Data streaming to index aggregators (CoinGecko mock-up)

A dedicated section in the GitHub repo will document deployment architecture, infra-as-code templates, and monitoring workflows.
