How to Launch a Meme Coin on Robinhood Chain in 60 Seconds (and What It Actually Costs)Guide
- You need a wallet on Robinhood Chain (chainId 4663) and a little ETH for gas — no code, no seed liquidity.
- Fill name/ticker/image, pick supply, optionally turn on a 1/3/5/10% tax and split it four ways, then deploy.
- Your token starts on a bonding curve; at about 4 ETH raised it graduates to Uniswap with liquidity locked forever.
- As creator you earn 5% of curve fees, 5% of the graduation fee, and your Treasury share of the post-graduation tax.
The first time I launched a coin on a bonding-curve launchpad I spent forty minutes on the wrong thing — the image — and about ninety seconds on the thing that decided whether anyone would hold it: the tax split. Do not be me. This is the launch flow on BigPump with the parts that matter flagged, and the real costs pulled from the contracts.
Before you click Create
- A wallet on Robinhood Chain. MetaMask, Rabby, OKX Wallet or anything WalletConnect. Connect on bigpump.ai and accept the prompt to add/switch to Robinhood Chain (chainId 4663). Gas is paid in ETH — there is no separate gas token.
- A little ETH. Bridge from Ethereum mainnet with the official bridge. Network fees on Robinhood Chain are a fraction of a cent, so "a little" really is a little; bring more only if you want to make the first buy yourself.
- Name, ticker, image. Upload artwork or generate it with the built-in AI tool. Socials and a description are optional but they are what make a stranger click.
Connecting also asks you to sign a login message. It is free, gasless, and approves nothing — it just proves you own the address.
The six steps
- Open Create Tax NFT and confirm you are on Robinhood Chain.
- Basics. Name, ticker, image, description.
- Supply. Pick a supply option. Remember the token is an x405 hybrid: the coin binds to NFTs at 1 NFT = 1,000,000 tokens.
- Tax Settings (the step that matters). Toggle Tax on, choose 1%, 3%, 5% or 10%, then split it across Treasury / Burn / Rewards / Liquidity so the sliders total 100%. If Treasury is above 0, enter the recipient wallet. Skip this and you launch a plain memecoin with no dividends.
- Vanity address. BigPump mines your contract a "bbb" suffix in the browser — a recognizable house style that the factory verifies on-chain. It costs 0.001 ETH.
- Deploy. Confirm in your wallet. You get a success screen with the trade page link. Share that link — the coin is live on its bonding curve immediately.
Spend your thinking on the tax split, not the logo. The split is the only knob that changes how holders behave.
What it costs — the real numbers
| Item | Amount | Notes |
|---|---|---|
| Network gas | Fraction of a cent | Robinhood Chain is an Arbitrum-Orbit L2 |
| "bbb" vanity address | 0.001 ETH | One-time, optional in principle, platform default |
| Seed liquidity | 0 | The bonding curve is the market; nothing to deposit |
| Bonding-curve trades | 1% per buy/sell | 95% platform, 5% to you the creator |
| Graduation settlement | 5% of pool ETH, once | 95% platform, 5% to you; e.g. 4 ETH → 0.2 ETH fee |
| Post-graduation trades | Your tax + 1% platform | Your Treasury share of the tax comes to your wallet in ETH |
Notice what is not in that table: a listing fee, a subscription, or a liquidity requirement. The curve prices the token from the first buy using a 1.5 ETH virtual reserve — that is a formula constant, not money you put in.
From curve to Uniswap: what happens after you launch
Your token lives on the bonding curve until about 4 ETH of real ETH has accumulated. Buys push price up the curve; sells pull it down; nobody can pull liquidity because there is no pool yet — the curve is the pool. Curve trades pay only the 1% fee; your tax is not applied on the curve.
At graduation the contract takes the one-time 5% settlement, creates a Uniswap V2 pair, adds the remaining ETH plus matching tokens as liquidity, and mints the LP tokens to the dead address. That liquidity is locked forever — not by a promise, by an address nobody controls. From this point every Uniswap trade is taxed at your rate plus 1%, the Rewards share starts paying holders in ETH, and your Treasury share starts landing in the wallet you named. The full mechanics are in what is a Tax NFT.
Three choices that decide whether anyone holds
- Put real weight on Rewards. A meaningful dividend share is the reason to hold through a dip instead of selling into it. A token that routes almost everything to Treasury is a fee token, and traders can read the split on the trade page.
- Keep Treasury honest. Use a wallet you are happy to have watched on the explorer, because it will be.
- Some Liquidity share is cheap insurance. It deepens the pool over time and softens volatility — which is also what keeps a chart from looking like a cliff.
Whatever you choose, say it out loud in the description. Holders forgive a high tax they understand; they do not forgive a surprise.
FAQ
Do I need to know how to code or deploy a contract?
No. BigPump deploys and configures the contract for you from the create form. You only sign the transaction.
Do I have to provide liquidity to launch?
No. The bonding curve is the market from the first buy. Uniswap liquidity is created automatically at graduation from the ETH the curve raised, and the LP is sent to the dead address.
How much ETH does it take to graduate?
About 4 ETH of real ETH accumulated in the curve pool. The 1.5 ETH virtual reserve you may see in the parameters only sets the starting price and is not deposited by anyone.
What do I earn as the creator?
5% of the 1% curve fee on every curve trade, 5% of the 5% graduation settlement, and — after graduation — the Treasury share of your own tax, paid in ETH to the wallet you set. Nothing here is a promise of profit; most memecoins go to zero.
