Treat transaction safety and operability as product behaviour.
ALHICA applies explicit trust boundaries, controlled side effects and operational evidence across gateway, connectors, data stores and administration.
- Least-privilege service boundaries
- Idempotent external effects
- Observable degradation and recovery
Separate public, provider and administrative trust
Gateway routes, provider callbacks and Aggregator Admin have different authentication, network and authorisation requirements.
Secrets remain server-side and logs are sanitised to avoid turning diagnostics into a credential or personal-data store.
- Independent route policies
- Server-side secrets
- Role-controlled administration
Observe the complete technical path
Real-time technical dashboards, metrics, structured logs and database evidence connect availability, traffic, latency and errors to transaction outcomes.
Database pools, backpressure, CPU, memory, disk and network are viewed in the same operational context rather than as isolated infrastructure numbers.
- Availability, traffic and latency
- Errors by integration and operation
- Database, queues and infrastructure resources
Degrade and recover predictably
Bounded timeouts, connection pools, backpressure and classified retries prevent a slow dependency from consuming the whole platform.
Pending effects move to explicit queues rather than disappearing or being retried without evidence.
- Timeout and pool limits
- Backpressure and saturation signals
- Dead-letter and reconcile paths
Separate integration, staging and production
The deployment model supports independent environments, distributed implementation and services isolated by provider where appropriate.
A connector can be released and scaled without redesigning the rest of the platform.
- Environment-specific configuration
- Independent provider services
- Controlled releases and rollback
Support the full integration lifecycle
Correlated evidence helps teams distinguish a platform, wallet, aggregator or provider problem quickly from testing through production.
Alerts, runbooks, backups, restore tests and recovery procedures turn detection into a controlled operational response.
- Correlated diagnosis
- Continuous monitoring and support
- Backup and recovery procedures
Review the end-to-end transaction threat model.
We can map trust boundaries, failure modes and recovery controls for the intended topology.
