+# WASL (وَصْل) Digital Wallet
+
+WASL is a bank-grade, secure P2P and merchant digital wallet platform tailored for Syria.
+
+## Tech Stack
+- **Backend**: Laravel 11 + Laravel Octane (Swoole driver)
+- **Mobile**: Flutter 3.x (Clean Architecture + BLoC/Cubit)
+- **Database**: PostgreSQL 16 (with transaction audit ledgers)
+- **Cache / Queue**: Redis 7
+- **Storage**: MinIO (S3-compatible secure private storage)
+- **Deployment**: Docker Compose
+
+## Architectural Core Principles
+- **ACID Compliance**: Ensuring complete database integrity for all financial mutation queries.
+- **Double-Entry Ledger**: Every transaction produces exactly 2 balancing ledger entries (debit and credit).
+- **Strict Minor Units**: All monetary values stored and processed as `BIGINT` minor units (e.g. SYP is stored as minor units to avoid floating-point inaccuracies).
+- **Pessimistic Locking**: `SELECT ... FOR UPDATE` with deterministic resource locking order to prevent deadlocks.
+- **Data Encryption**: AES-256 field-level encryption for sensitive PII (Phone number, National ID).
+- **Audit Logging**: Immutable ledger tracking all authentication, registration, and transfer activities.
