The short version

Origo lets approved creators bring a coin to life on Robinhood Chain, and each coin is priced by its own curve from its very first trade.

The moving parts

• One Origo contract on Robinhood Chain mints every coin, keeps the ETH behind each curve and settles every trade.
• A coin data service watches the chain to fill the lists, charts, history and certificate progress. Trades never depend on it: prices come live from the contract.

Before you begin

1. Bring a wallet

   Origo works with any browser wallet that introduces itself to the page, and shows that wallet's own name and icon. One wallet installed means one click to connect; several means you pick. With none, the button leads to a directory of wallets. On a phone, use the browser inside your wallet app.

2. Point it at Robinhood Chain

   Origo lives on Robinhood Chain (chain id 4663). When your wallet sits on another network, Origo offers to move it, and first teaches it the network if it has never seen it.

3. Keep a little ETH there

   Creating, buying and gas are all paid in ETH on Robinhood Chain.

Origo will never ask for a seed phrase or a private key. You sign every transaction yourself, inside your wallet.

Create a coin

Only approved wallets can create a coin. It all happens on the Create page.

1. Pick a name and ticker

   Up to 32 characters for the name and 10 for the ticker, using plain letters, digits, spaces and simple punctuation.

2. Add the links

   A website and an X account are required; Telegram is up to you. They are saved on Robinhood Chain with the coin and appear on its page.

3. Choose a picture, or skip it

   PNG, JPEG, WebP or GIF. Origo trims it to a square, saves it, and names it after its fingerprint, a hash of the saved file that travels with the coin's links. That way anyone can confirm the picture shown is the one the coin was born with. Skip it, and the art is drawn from the coin's address.

4. Make a first buy, or skip it

   The creator may buy into the coin within the same transaction, up to reading with the trade fee taken from that, under its own slippage limit between 0.1 and 10 percent. You are warned when that first buy would shift the price by over 5 or 10 percent.

5. Preview, then sign

   The preview lists the name, ticker, links, picture, creation fee (reading), first buy and the total leaving your wallet. The contract is then asked whether creating is running, your wallet may create, a place is free and the first buy is within limits. Nothing goes out until you sign.

6. Welcome to the world

   The coin is born with 1,000,000,000 tokens and 6 decimals, tradable in the same block. You get links to its page and to the birth transaction.

Trading

Each coin page carries a Buy and Sell panel. Its prices are read live from the contract, so trading carries on even when the coin data service lags.

Slippage and the least you accept

Your max slippage, 1 percent by default and anywhere from 0.1 to 10, sets the least you will accept. If the price runs past it, the trade is refused. If the numbers worsen between your preview and your signature, you are asked to look again. A price shift above 5 percent, and above 10, comes with a warning.

The step sheet

A trade moves through four steps: Check, Wallet, Block and Done. Before your wallet even opens, the contract confirms buying is running, the amount fits under the ceiling and the price is inside your slippage, or for a sale, that you hold enough and the allowance covers it. A preview expires after 20 minutes.

Trades start at 0.000001 ETH.

Price and the ceiling

A coin begins with 1,000,000,000 tokens on a curve of its own. Buying pushes the price up and selling pulls it down, following a formula written into the contract.

The ETH behind a coin's curve can grow to reading, its ceiling. Once there, new buys wait until someone sells. Sellers can always leave, and each sale frees room for buyers again.

The gauge around each coin

A coin's board is framed by small ticks. Each tick stands for 0.1 ETH of the ceiling, so the lit ticks show what the curve holds. Buys light more of them and sells dim them. All lit means the ceiling is reached.

What it costs

Origo earns from two fees, both in ETH.

• Trade fee, reading. Charged on each buy and each sell: taken from the ETH you spend when buying, and from the ETH you get when selling. It was fixed when the contract was deployed and can never change.
• Creation fee, reading. Paid once per new coin.

Both pile up inside the contract and can be paid out to one place only, the treasury, listed under Numbers and addresses.

Each transaction also costs a little gas on Robinhood Chain, paid in ETH by your wallet.

Who can do what

• The ETH behind a curve belongs to its traders. The only ways out are a seller cashing out their own tokens and fees flowing to the treasury.
• Selling can never be put on hold, by anyone.
• Set in stone at deployment: the trade fee, the curve, the ceiling and the creator's largest first buy. The contract cannot be upgraded.

What could go wrong

• A contract flaw. ETH held by the contract could be lost or frozen. The design gives no role a way to stop selling, yet a flaw still could.
• Coin data falls behind. Lists, charts and totals may show stale numbers, while trades keep using the contract's live price.
• Creation rules change. The owner can approve or remove creators, or open creating to all. Trading is never affected.
• Buying goes on hold. The guardian or the owner can halt buys on all coins, say while something is investigated, and only the owner restarts them. Selling continues throughout.
• The number of places changes. The owner can add or remove places for new coins. Trading stays as it is, though more places let more ETH collect in the curves.

Numbers and addresses

Values tagged as contract readings come live from the chain; the rest come from the coin data service.
