Use Create on Base or Robinhood Chain. Switch the chain in your wallet first. One confirmation creates the token and opens the market.

Steps

1. Connect your wallet on launch.basecat.app.
2. Enter a name, ticker, and image. Those freeze after launch.
3. Pick a quote (what people buy and sell against).
4. Pick a mode — see Modes.
5. Pick a fee of 1%, 2% (default), or 3%. See Fees.
6. Optionally set a first buy. Leave it at zero if you do not want a creator bag.
7. Read the review screen. Confirm in your wallet. Creation costs 0.001 ETH.

If anything in that transaction fails, nothing is created.

After it lands

The coin is live. Anyone can buy. You cannot mint extra tokens, pause trading, or pull liquidity.

Selling needs buyers first. If nobody has bought yet, there may be nothing to sell into. That is normal at the start.

The coin page shows the lock, the fee, the first-20-seconds countdown, and (if you used one) how much you bought at launch.

You choose

Field	What to know
Name / ticker / image	Cannot be edited later.
Quote	ETH, a dollar stable, $BASECAT, wrapped majors on Base, or a listed stock token.
Mode	Creator, self-burn, yard-burn, or Rewards.
Fee	1% / 2% / 3%. Locked for that coin.
First buy	Optional. Cap is 10% of supply. Not locked.

You cannot choose

• A custom supply (it is always 1 billion)
• A bonding curve
• Unlocking liquidity later
• Changing the fee after launch
