+# Dash Platform Balance Checker
+
+A collection of Rust command-line tools for checking Dash Platform balances using various SDK configurations and providers.
+
+## Overview
+
+This package contains multiple binary targets that demonstrate different approaches to fetching Dash Platform balances:
+
+- **dash-platform-balance-checker**: Main balance checker with full SDK integration (supports both mainnet and testnet)
+- **dash-platform-balance-simple**: Direct DAPI client approach without full SDK overhead  
+- **dash-platform-balance-trusted**: Uses trusted HTTP context provider instead of Core RPC
+
+## Building
+
+```bash
+cargo build --release
+```
+
+## Running
+
+Each binary can be run independently:
+
+```bash
+# Main balance checker (requires identity ID)
+cargo run --bin dash-platform-balance-checker <identity-id> [--testnet]
+
+# Direct DAPI implementation (hardcoded testnet example)
+cargo run --bin dash-platform-balance-simple
+
+# With trusted provider (hardcoded testnet example)
+cargo run --bin dash-platform-balance-trusted
+```
+
+## Dependencies
+
+- `dash-sdk`: Dash Platform SDK
+- `rs-dapi-client`: DAPI client implementation
+- `dapi-grpc`: gRPC definitions for DAPI
+- `dpp`: Dash Platform Protocol
+- `drive-proof-verifier`: Proof verification
+- `rs-sdk-trusted-context-provider`: Trusted HTTP context provider
+- `tokio`: Async runtime
+- `anyhow`: Error handling
+
+## Usage
+
+### Identity ID Format
+
+The tools accept identity IDs in Base58 format. Example:
+```
+5DbLwAxGBzUzo81VewMUwn4b5P4bpv9FNFybi25XB5Bk
+```
+
+### Examples
+
+#### Using the main balance checker
+```bash
+# Check balance on mainnet with local Core (default)
+cargo run --bin dash-platform-balance-checker 5DbLwAxGBzUzo81VewMUwn4b5P4bpv9FNFybi25XB5Bk
+
+# Check balance on testnet
+cargo run --bin dash-platform-balance-checker 5DbLwAxGBzUzo81VewMUwn4b5P4bpv9FNFybi25XB5Bk --testnet
+
+# Check balance with custom Core connection
+cargo run --bin dash-platform-balance-checker 5DbLwAxGBzUzo81VewMUwn4b5P4bpv9FNFybi25XB5Bk \
+  --core-host 192.168.1.100 --core-port 9998 \
+  --core-user myuser --core-password mypass
+
+# Check balance without Core connection
+cargo run --bin dash-platform-balance-checker 5DbLwAxGBzUzo81VewMUwn4b5P4bpv9FNFybi25XB5Bk --no-core
+
+# Show help
+cargo run --bin dash-platform-balance-checker --help
+```
+
+#### Command Line Options
+- `--testnet` - Use testnet instead of mainnet (default: mainnet)
+- `--core-host <host>` - Core RPC host (default: localhost)
+- `--core-port <port>` - Core RPC port (default: 9998 for mainnet, 19998 for testnet)
+- `--core-user <username>` - Core RPC username (default: dashrpc)
+- `--core-password <password>` - Core RPC password (default: password)
+- `--no-core` - Skip Core connection (may limit some functionality)
+
+#### Expected Output
+```
+Dash Platform Balance Checker - Mainnet
+=====================================
+
+Identity ID: 5DbLwAxGBzUzo81VewMUwn4b5P4bpv9FNFybi25XB5Bk
+Parsed Identity ID: 5DbLwAxGBzUzo81VewMUwn4b5P4bpv9FNFybi25XB5Bk

+```
+
+## Network Configuration
+
+The main balance checker supports both networks:
+
+### Mainnet (default)
+- https://dapi.dash.org:443
+- https://dapi-1.dash.org:443
+- https://dapi-2.dash.org:443
+
+### Testnet (with --testnet flag)
+- https://52.13.132.146:1443
+- https://52.89.154.48:1443
+- https://44.227.137.77:1443
+- (and others)
+
+## Prerequisites
+
+- Rust toolchain (1.70+)
+- Internet connection to reach network nodes
+- Dash Core node (optional but recommended):
+  - Default ports: 9998 (mainnet) or 19998 (testnet)
+  - Default credentials: dashrpc/password
+  - Can be skipped with `--no-core` flag
