description	Core Monad blockchain operations - EVM wallet generation, MON transfers, and balance checks. Use when the user needs to generate EVM keypairs, send MON or ERC20 tokens, check balances, or interact with Monad RPC. Provides low-level primitives for EVM applications on Monad.

Monad

Core Monad (EVM) blockchain operations: wallet generation, MON transfers, and balance checking.

Quick Start

# Generate a new EVM wallet
monad-keygen.js

# Check MON balance
monad-balance.sh <address>

# Transfer MON
monad-transfer.js <to_address> <amount_mon>

# Check ERC20 token balance
monad-token-balance.sh <token_address> <wallet_address>

Configuration

Use environment variables:

export MONAD_PRIVATE_KEY="0x..."   # 0x-prefixed hex private key
export MONAD_ADDRESS="0x..."       # EVM wallet address
export MONAD_RPC_URL="https://monad-mainnet.drpc.org"
export MONAD_TESTNET="false"       # Set to "true" for testnet (chain 10143)

Testnet Mode

Set MONAD_TESTNET=true to switch all Monad operations to testnet. This automatically changes:

• Chain ID: 143 (mainnet) -> 10143 (testnet)
• RPC URL: monad-mainnet.drpc.org -> monad-testnet.drpc.org
• nad.fun API: api.nadapp.net -> dev-api.nad.fun
• All contract addresses (LENS, Router, Curve, etc.)

You can still override MONAD_RPC_URL manually — it takes precedence over the testnet default.

Overview

Monad is a high-performance EVM-compatible blockchain with:

• 1 second block times: Fast finality
• 10,000+ TPS: High throughput via parallel execution
• Full EVM compatibility: Use standard Ethereum tools (viem, ethers.js)
• Native token: MON (18 decimals, like ETH)

Key Concepts

Concept	Description
Private Key	secp256k1 key, 0x-prefixed 64 hex chars
Address	0x-prefixed 40 hex chars (checksummed)
Wei	Smallest MON unit (1 MON = 10^18 wei)
Gas	Transaction fee unit, similar to Ethereum

Scripts

Wallet Management

# Generate new EVM wallet (outputs JSON with address and privateKey)
monad-keygen.js

# Check MON balance (returns JSON with mon and wei)
monad-balance.sh <address>

Transfers

# Transfer MON to address
monad-transfer.js <to_address> <amount_mon>

Token Operations

# Check ERC20 token balance
monad-token-balance.sh <token_address> <wallet_address>

Network

Field	Value
Chain ID	143
RPC URL	https://monad-mainnet.drpc.org
Native Token	MON (18 decimals)
Block Time	~1 second

Security Notes

• Never share private keys - They control all funds
• Use dedicated wallets - Don't use main wallet for bots
• Verify addresses - Check recipient before transfers
• Store keys securely - Use environment variables, never hardcode

NOTE: Scripts are available on PATH. You can run them by short name (e.g. monad-balance.sh).
