Nad.fun Monagotchi Trader

Manage $MONA tokens on the Monad blockchain for Monagotchi pet interactions. This skill handles burning tokens when the owner wants to feed, play with, clean, or heal their pet.

Overview

$MONA is the fuel for your Monagotchi. Every pet action burns tokens — they're sent to the dead address and permanently removed from supply. The more you care for your pet, the scarcer $MONA becomes.

Setup

Install dependencies first:

cd {baseDir}/scripts && npm install

Configuration

Required environment variables (set in

~/.openclaw/openclaw.json

under

skills.entries.monagotchi-trader.env

):

MONAGOTCHI_TOKEN_ADDRESS=0x...       # $MONA token contract on Monad
MONAD_PRIVATE_KEY=0x...              # Owner wallet private key (for signing burn txs)
MONAD_RPC_URL=https://...            # Monad RPC endpoint

Action Costs

Action	$MONA Burned
Feed	1,000
Play	2,500
Clean	1,500
Heal	5,000
Sleep/Wake	0 (free)
Status	0 (free)

These costs are defined in the

{baseDir}/scripts/monagotchi-trader.mjs

config and can be adjusted.

How Burning Works

Burning = transferring tokens to the dead address:

0x000000000000000000000000000000000000dEaD

This is a standard ERC-20

transfer()

call. Tokens sent to the dead address are permanently out of circulation.

Operations

Check Balance

node {baseDir}/scripts/monagotchi-trader.mjs balance

Returns JSON with the owner's $MONA balance and what they can afford.

Burn Tokens (for a pet action)

node {baseDir}/scripts/monagotchi-trader.mjs burn feed
node {baseDir}/scripts/monagotchi-trader.mjs burn play
node {baseDir}/scripts/monagotchi-trader.mjs burn clean
node {baseDir}/scripts/monagotchi-trader.mjs burn heal

Each command:

1. Checks the owner's $MONA balance
2. Verifies sufficient tokens for the action
3. Sends the required amount to 0x...dEaD
4. Waits for tx confirmation
5. Outputs JSON with the tx hash on success or an error message on failure

Get Token Info

node {baseDir}/scripts/monagotchi-trader.mjs info

Returns token name, symbol, total supply, owner balance, and bonding curve progress.

Output Format

All commands output JSON to stdout. Status/debug messages go to stderr. Parse stdout for structured results:

{"success": true, "action": "feed", "burned": 1000, "txHash": "0x...", "remainingBalance": "45000.0"}

On failure:

{"success": false, "error": "Insufficient $MONA. Need 1000, have 500.0"}

Security

⚠️ The private key is stored as an environment variable. This is the owner's wallet key used to sign burn transactions. Keep it safe:

• Never commit it to git
• Set it in

  ~/.openclaw/openclaw.json

  under

  skills.entries.monagotchi-trader.env

• Consider using a dedicated wallet with only $MONA and a small amount of MON for gas

Integration with monagotchi-controller

The typical flow when the owner requests a pet action:

1. monagotchi-controller checks pet status via

   curl -s http://${MONAGOTCHI_ESP32_IP}/pet

2. monagotchi-controller determines which action to take and its cost
3. monagotchi-trader checks $MONA balance —

   node {baseDir}/scripts/monagotchi-trader.mjs balance

4. monagotchi-trader burns the required $MONA —

   node {baseDir}/scripts/monagotchi-trader.mjs burn <action>

5. If burn tx confirms → monagotchi-controller calls the ESP32 endpoint
6. If burn fails → report the error, don't execute the action
7. monagotchi-environment updates room lights/temp based on pet state

Examples

• "Feed my pet" →

  node {baseDir}/scripts/monagotchi-trader.mjs burn feed

  → on success, controller calls POST /feed
• "What's my $MONA balance?" →

  node {baseDir}/scripts/monagotchi-trader.mjs balance

  , report back
• "Heal and clean my pet" → burn 5,000 for heal → call /heal → burn 1,500 for clean → call /clean
• "Can I afford to play?" → check balance → compare against 2,500 → respond yes/no
