Hero Ledger

A NEAR-compatible blockchain with its own network, validators, and token economy.

• 9 Smart Contracts: SPORE, GLD, USDH tokens, SPOREX exchange, DNS, Credit Vault, Groups, KVS, Hosting
• heroledger CLI: Command-line interface for all operations
• Rhai Scripting: Automation and testing scripts

Quick Start

Prerequisites: make and curl must be installed.

# Ubuntu/Debian
sudo apt-get install make curl

# macOS
xcode-select --install  # includes make
brew install curl       # if needed

Bootstrap (From Nothing)

git clone https://forge.ourworld.tf/lhumina_code/hero_ledger.git
cd hero_ledger
make bootstrap

This will:

1. Install system packages (Ubuntu/Debian only)
2. Install Rust and cargo-near
3. Build all contracts and CLI
4. Install binaries to ~/hero/bin
5. Start local chain and deploy contracts

Development Workflow

make setup           # Install dependencies (once)
make build           # Build debug binary (fast)
make install         # Build and install to ~/hero/bin
make test            # Run smoke + full tests

For optimized builds:

make build-release   # Build release binary
make install-release # Install release binary

Available Targets

make help            # Show all targets

# Setup
make setup           # Install system packages, Rust, cargo-near

# Build
make build           # Debug build (contracts + CLI)
make build-release   # Release build (optimized)
make build-contracts # Build WASM contracts only
make check           # Fast syntax check
make fmt             # Format code
make lint            # Run clippy

# Install
make install         # Debug build to ~/hero/bin
make install-release # Release build to ~/hero/bin

# Chain Management
make bootstrap       # Full setup from nothing
make chain-init      # Initialize single-node chain
make chain-destroy   # Destroy local chain and clean up

# Testing
make test            # Run all tests
make test-smoke      # Quick smoke test
make test-full       # Full system test
make test-unit       # Rust unit tests

make clean           # Remove build artifacts

CLI Usage

# Account operations
heroledger list                              # List accounts
heroledger <account> info                    # Account details
heroledger <account> send SPORE 100 <to>     # Send tokens

# SPOREX Exchange
heroledger <account> x rates                 # View rates
heroledger <account> x fund SPORE 100        # Deposit
heroledger <account> x withdraw SPORE 50     # Withdraw

# KVS (Key-Value Store)
heroledger kvs namespaces                    # List namespaces
heroledger <account> kvs create myapp.config # Create namespace
heroledger <account> kvs set myapp.config key value

# DNS
heroledger dns available example.hero        # Check availability
heroledger <account> dns register example.hero 12  # Register for 12 months

# Groups
heroledger groups list                       # List groups
heroledger <account> groups create mygroup "Description"

# Credit Vault
heroledger credit spenders                   # List spenders
heroledger <account> credit deposit bucket1 100

Run heroledger --help for full command reference.

Rhai Scripting

Automate workflows with Rhai scripts:

near_localnet("http://localhost:3030");
near_accounts_dir("./accounts");

let alice = account("my_test_1");
print(`Balance: ${alice.balance_near()} NEAR`);

token_send()
    .from("my_test_1")
    .to("my_test_2")
    .amount(100)
    .token("spore")
    .execute();

Run scripts:

heroledger my_script.rhai
heroledger rhaitests/smoke/test_smoke.rhai      # 9 smoke tests
heroledger rhaitests/system/test_full_system.rhai  # 35 system tests

See the Rhai scripting module in src/rhai/ for more examples.

Testing

make test              # Run smoke + full tests
make test-smoke        # Quick smoke test
make test-full         # Full system test
make test-unit         # Rust unit tests
