COIN
TO PLAY
Your receipt
Pick a slot, type your order and press VEND. The answer prints here.
Stock a slot
Put your GPU in the machine. You set the price per 1,000 tokens, buyers pick your slot, and you get paid for every token your model prints, minus a 3% machine fee.
Your earnings
New earnings are held for 15 minutes so buyers can report a bad receipt. Then they move to your coins and you can cash out from the coin slot.
Feature your stall
Pin your stall to the top row of the machine with a flashing HOT tag for 24 hours. Featured stalls get picked first.
3,000 coins, paid from your coins. Only a few spots at a time.
Sell from this browser
Runs a small open model on your graphics card, right in this tab. Nothing to install. Keep the tab open: closing it closes your stall.

Sell from your GPU rig
Bigger models, several jobs at once. A small app on your machine passes jobs to Ollama.
- Install Ollama and pull a model, for example
ollama pull llama3.1:8b. - Download vendo-node.js (needs Node 22 or newer).
- Get your seller key, then run the command below in the folder where you saved the file.
Popular rig models. Tap one to add it to your command, and pull it first with ollama pull.
Connect your wallet, then get a seller key to see your command.
Getting a new key turns off the old one. Treat the key like a password: anyone with it can sell as you.
Stake $VENDO
Staked stalls rank higher in the machine. Stake, unstake and withdraw on the Wallet page.

How to use this machine
Two things to know
$VENDO is your pass. Hold it in your wallet to use the machine. It is never spent.
Coins pay for answers. Buy them with ETH, spend a few per answer, cash out what's left any time. Green FREE slots need neither.
VENDO is a marketplace. The machine itself owns no GPUs and sells no AI. Every slot is stocked by another $VENDO holder running an open model on their own hardware.
To buy
- Hold at least 10,000 $VENDO in your wallet (staked counts too), then connect the wallet. Signing in costs nothing.
- Buy a coin pack on the Wallet page, paid in ETH on Robinhood Chain (1 ETH buys 1,000,000 coins). A typical answer costs a few coins.
- Pick a slot by tapping it or typing its code on the keypad. The tag under each slot shows about how many coins one answer costs. Longer answers cost more.
- Write your order and press VEND. The machine holds enough coins for the longest answer, then charges only for tokens actually printed and returns the rest.
- Rate the receipt. If it's junk, report it within 15 minutes and the seller's payment stays frozen until it's reviewed.
To sell
- Hold the same 10,000 $VENDO minimum, and stake $VENDO on the Wallet page if the machine asks for a seller stake.
- Open a stall from your browser, or run the node app next to Ollama on a GPU rig.
- Set your price. Cheaper, well-rated and staked stalls sit higher in the machine.
- Earnings unlock after the hold window. Cash out on the Wallet page: the vault pays ETH to your wallet.
The fine print
Coins live on the VENDO server. ETH sits in the vault contract; moving coins between buyers and sellers happens off-chain so every job is instant and free. Cashing out uses a voucher signed by the server, so you are trusting the operator like you would a custodial exchange. The vault caps how much ETH can leave per day, which limits damage if the signing key were ever stolen.
Tokens are counted by the machine, not the seller. The count is an estimate (about 4 characters per token) applied the same way to every slot, so sellers can't pad their bill.
Browser slots run small models. They are quick and cheap, and they make mistakes. Pick a bigger model from a node stall for harder questions.
Your prompt goes to the seller's machine. Don't put passwords, keys or anything private in an order.
Fees. The machine keeps 5% of each sale (wallets holding 100,000 $VENDO or more pay half). The vault takes 0% of each deposit and 0% of each cash-out. Vault fees are written into the contract and can never go above 5%. When a cheating seller is slashed, part of the slashed $VENDO goes to the VENDO team and the rest is burned.
Wallet
Buy coins with ETH, cash them back out, and stake $VENDO. Nothing leaves your wallet until you confirm it in MetaMask.
Connect your wallet
Connect to see your coins, buy more, or stake.
Buy coins
Pick a pack. A short answer costs a few coins.
Cash out
Turn coins you don't need back into ETH. Minimum 1,000 coins.
Stake $VENDO
Lock $VENDO to open a stall and rank higher in the machine. Staked $VENDO also counts toward your machine pass and half fees. If you serve junk answers, part of it can be slashed. Unstaking takes 7 days, then you withdraw it for free (or early, for a fee that shrinks every day).
