Instructions for the uninitiated

How to mint nothing, starting from nothing.

A plain-language guide for people who have never touched a blockchain and would like to own a Pueblo Void anyway. No money changes hands. The only thing you risk is your afternoon.

TIME REQUIRED: ~10 MINUTES · COST: $0.00 · PRIOR KNOWLEDGE: NONE · OUTCOME: NONE

STEP 1 OF 4

Get a wallet

A wallet is a small program that holds your blockchain account and signs things on your behalf. It does not hold your money for this exercise, because there is no money. We suggest MetaMask: it is free, widely used, and works as a browser extension or a phone app.

Go to metamask.io/download and install it for your browser (Chrome, Firefox, Edge, Brave) or your phone. Only download from that address.
Open it and choose Create a new wallet. Pick a password. This password only unlocks the app on this device.
MetaMask will show you a Secret Recovery Phrase: 12 ordinary words. Write them on paper, in order, and put the paper somewhere safe. This phrase is the wallet. Anyone who has it owns everything in it, forever.
Confirm the phrase when asked. You are done. The long string starting with 0x at the top of MetaMask is your address: think of it as your account number. It is safe to share.

Never type your recovery phrase into a website. Not this one, not any. No legitimate site, support agent, or protocol needs it. Pueblo Inutile Protocol will never ask for it, partly on principle and partly because we have no staff.

STEP 2 OF 4

Add the Monad Testnet network

Pueblo Void lives on Monad Testnet, a practice version of the Monad blockchain where the currency is deliberately worthless. Your wallet needs to know it exists.

The easy way

Go back to the main page, click Connect Wallet, approve the connection in MetaMask, and when the site asks to switch networks, click Switch Network. MetaMask will offer to add Monad Testnet for you. Approve it. Skip to step 3.

The manual way

If you prefer to do it yourself: in MetaMask open the network menu (top left), choose Add a custom network, and enter exactly:

Network name	Monad Testnet
Default RPC URL	https://testnet-rpc.monad.xyz
Chain ID	10143
Currency symbol	MON
Block explorer URL	https://testnet.monadscan.com

Save it and select it. The top of MetaMask should now say Monad Testnet and your balance should read 0 MON. That is correct; we will fix it next.

STEP 3 OF 4

Get free testnet MON

Every blockchain transaction costs a small fee, called gas, paid in the network's currency. On Monad Testnet that currency is testnet MON, which has no value and is handed out free by a faucet. Minting a Void is free, but the gas still has to come from somewhere.

In MetaMask, click your address at the top to copy it.
Open the official faucet at faucet.monad.xyz, paste your address, and request tokens. No sign-up is needed. If it says you are rate-limited, wait and try again, or use the QuickNode faucet instead.
Within a minute your MetaMask balance should show some MON. Even a fraction is enough for dozens of mints.

Testnet MON cannot be sold, swapped for real money, or sent to a real network. If anyone offers to buy yours, they are confused or lying.

STEP 4 OF 4

Mint your Void

Return to the main page and click Connect Wallet if you have not already. Approve in MetaMask.
Click Mint Void. MetaMask will pop up asking you to confirm a transaction. Check that the amount is 0 MON plus a tiny gas fee, then click Confirm.
Wait a few seconds. The page will show your new Void under Your Voids, and the counter of total voids inscribed will go up by one. You can also look it up on the block explorer using your address.

Congratulations. You now own a cryptographically verified certificate of absence. It does nothing, will always do nothing, and is yours.

Proceed to the mint →

Questions people actually ask

Did I just spend real money?

No. Monad Testnet is a sandbox. Nothing on it has monetary value, including the gas you paid and the Void you received.

MetaMask says "insufficient funds."

You need a little testnet MON for gas. Go back to step 3. Also make sure MetaMask is on Monad Testnet and not on Ethereum or Monad Mainnet, which are different networks with real money on them.

The site says I am on the wrong network.

Click Switch Network when prompted, or pick Monad Testnet from MetaMask's network menu. If it is not listed, add it with the table in step 2.

Can I sell my Void?

No. It has no value, no market, and no purpose. This is the product working as intended.

Is this safe?

The mint asks you to sign one transaction that sends 0 MON to the contract. It never asks for your recovery phrase, never asks for permission to move other tokens, and cannot touch anything on a real network. The contract address is shown on the main page, and you can read it on the explorer. Use a wallet you created just for this if you like; we did.

Why would anyone do this?

To learn how a wallet, a network, a faucet, and a transaction fit together, with nothing at stake. Everything you just did is exactly what you would do on a real network, minus the consequences. Also, the Void is quite pretty.

Glossary

Wallet: An app that holds your keys and signs transactions. MetaMask is one of many.
Address: Your public account number, a long string beginning with 0x. Safe to share.
Secret recovery phrase: Twelve words that regenerate your wallet anywhere. Never share. Never type into a website.
Network, or chain: A particular blockchain. Monad Mainnet is the real one; Monad Testnet is the practice one. They do not talk to each other.
Gas: The small fee a network charges to process a transaction, paid in that network's own currency.
Faucet: A website that gives away testnet currency for free so people can experiment.
NFT: A token that is one of a kind and belongs to one address at a time. A Void is an NFT containing nothing.
Block explorer: A website for looking up any address, transaction, or contract on a network.
