 # Java Wallet (Monolith)
 
-This project is now converging to a **single Spring Boot wallet service**.
+Java Wallet is a **production-oriented Spring Boot wallet platform** for centralized exchanges, payment systems, and custodial services.  
+It provides unified wallet management, blockchain synchronization, deposit detection, sweep automation, and admin tooling in a single deployable service.
 
-## What changed
-- Single startup service (`wallet-webapi` as app runtime)
-- No RabbitMQ required
-- No xxl-job required
-- HSM capabilities are invoked in-process
-- tokencore dependency unified to `com.github.galaxyscitech:tokencore:2.0.0`
+---
+
+## Why this project
+
+This repository is converging to a **single-service architecture** to make deployment and operations simpler:
+
+- One startup service (`wallet-webapi` runtime)
+- No RabbitMQ dependency
+- No xxl-job dependency
+- HSM capabilities invoked in-process
+- Unified tokencore dependency: `com.github.galaxyscitech:tokencore:2.0.0`
+
+This means fewer moving parts, easier troubleshooting, and faster onboarding for developers and DevOps teams.
+
+---
+
+## Product capabilities
+
+- **Wallet lifecycle management**: create, query, and manage wallet addresses
+- **Deposit scanning**: continuously detect inbound transfers
+- **Chain synchronization**: sync on-chain data into internal services
+- **Sweep automation**: consolidate balances based on strategy
+- **Fee supply scheduling**: ensure fee accounts are topped up when needed
+- **Admin operations**: operational controls and configuration through admin APIs
+
+---
+
+## Typical use cases
+
+### 1) Centralized Exchange (CEX)
+Use Java Wallet as the deposit/withdrawal backend for multi-chain assets:
+- Generate deposit addresses per user
+- Detect incoming deposits and credit user balances
+- Sweep funds from hot collection addresses to treasury/cold paths
+
+### 2) Payment or Merchant Platform
+Integrate chain deposits as payment rails:
+- Assign invoice addresses
+- Confirm on-chain settlement
+- Trigger internal payment workflows after confirmations
+
+### 3) Custodial Asset Service
+Operate managed wallets for institutional users:
+- Centralize key and wallet operations
+- Track chain states
+- Keep operational history with admin audit logs
+

+
+## Quick start
+
+### Option A: Run with Docker Compose (recommended)
 
-## Quick Start
-### 1) Start with Docker Compose
 ```bash
 docker compose up -d --build
 ```
 
 Services:
-- `app` on `http://localhost:8080`
-- `mysql` on `localhost:3306`
+- `app`: `http://localhost:8080`
+- `mysql`: `localhost:3306`
+
+### Option B: Run locally with Gradle
 
-### 2) Start manually
 ```bash
 ./gradlew :wallet-webapi:bootRun
 ```
 
-## API
+---
+
+## First-time user path (10-minute onboarding)
+
+1. **Start services** using Docker Compose.
+2. **Open Swagger UI**: `http://localhost:8080/swagger-ui/index.html`
+3. **Check health/basic endpoints** from Swagger.
+4. **Create or query wallet resources** via Wallet API.
+5. **Observe scheduler-driven behaviors** (deposit scan, sync, sweep) via logs and DB state.
+
+If you are new to this project, using Swagger first is the fastest way to understand request/response models.

 - Wallet API: `/wallet/v1`
 - Blockchain API: `/block_chain/v1`
 - Admin API: `/admin`

+## Runtime configuration (DB-driven)
+
+Runtime scheduler behavior is controlled through `sys_config` keys:

-Core runtime behavior is expected to be DB-config driven. Current scheduler keys already supported in `sys_config`:

-## Security notes
-- Do not use default passwords in production.
-- Never expose keystore password, mnemonic, or private key in logs.
-- Keep RPC credentials masked in management APIs.
+> Suggestion: keep intervals conservative in production first, then tune based on chain throughput and DB load.
+
+---
+
+## Security recommendations
+
+- Never use default passwords in production.
+- Never expose keystore passwords, mnemonic phrases, or private keys in logs.
+- Mask RPC credentials in admin/management outputs.
+- Restrict admin endpoints with network controls and strong authentication.
+
+---
+
+## Database notes
+
+- Audit table: `wallet_admin_audit_log` (admin configuration change history)
+
+---
+
+## README optimization ideas (for next iteration)
+
+To make this project even easier for users, consider adding:
+
+1. **Architecture diagram** (single-service + MySQL + chain nodes)
+2. **End-to-end demo flow** (create address → deposit → detect → sweep)
+3. **API cookbook** with copy-paste `curl` examples
+4. **Environment matrix** (`dev` / `staging` / `prod`) with recommended defaults
+5. **Troubleshooting guide** (common startup, DB, RPC, and sync issues)
+6. **FAQ** for operations and security best practices
 
-## Database updates
-- New audit table: `wallet_admin_audit_log` (admin config change history).
+These additions reduce onboarding time and lower support burden.
