How to launch a token on Robinhood Chain
IN SHORT
To launch a token on Robinhood Chain you bridge ETH to the chain (ID 4663), create the token through Pons — which deploys it straight into a locked Uniswap V3 pool paired against WETH — and buy your own allocation in the same movement, either inside the launch call itself or as one router multicall across many wallets.
The whole flow can be rehearsed free on the testnet (chain ID 46630) before you spend anything. The part people get wrong is not the deployment; it is the gap between the token going live and their own buys landing.
What you need before you start
- ETH on Robinhood Chain. Enough for the Pons launch fee, whatever you plan to buy of your own token, and gas. Gas is the cheapest part — around 0.01 gwei.
- A deployer wallet. The wallet that signs the launch becomes the token creator and is the one Pons credits with creator fees.
- Token basics. Name, symbol, image and any social links you want attached to the launch.
- A plan for the buys. How many wallets, how much each, and what you intend to do afterwards. This is the part worth thinking hardest about.
Step by step
- Get ETH onto Robinhood Chain. Bridge ETH to Robinhood Chain (chain ID 4663) from Ethereum, or use the testnet faucet if you are rehearsing. You need enough to cover the launch fee, your own buys and gas — gas itself is negligible at around 0.01 gwei.
- Rehearse the launch on testnet. Run the whole flow on Robinhood Chain testnet (chain ID 46630) first. It is free, it uses the same wizard, and it is the only way to find a configuration mistake without paying for it.
- Configure the token and the buys. Set the token name, symbol and image, then decide how many buyer wallets will participate and how much each spends. Vary the per-wallet amounts so the buys do not all look identical on-chain.
- Simulate the bundle. Dry-run the exact transaction set before spending anything. A simulation checks that funds are sufficient, that the pool will exist, and that no individual buy would revert.
- Fire the launch. Send it. The Pons factory deploys the token into a locked Uniswap V3 pool, and your buys execute either inside that same launch call or as a single router multicall, so they land together or not at all.
- Manage the position. After launch, track the buyer wallets and sell in a controlled way. Selling every wallet at once is as visible as buying with every wallet at once.
What actually happens on-chain
It is worth understanding the mechanics, because they explain why the timing matters so much.
1. The launch transaction
Pons’ factory takes your token parameters and, in one transaction, deploys the ERC-20, creates a Uniswap V3 pool paired against WETH at the 1% fee tier, and locks the liquidity position in a locker contract. If you included a creator buy, it executes inside this same call — meaning it happens in the launch block itself.
2. The restriction window
For a configured number of blocks after launch, Pons enforces per-wallet and per-transaction caps, and in the launch block only the creator’s own buy can execute. Anyone else trying to buy in that block gets rejected.
There is a subtlety here that catches people out: inside a contract on an Arbitrum Orbit chain, block.number returns the L1 block estimate, which only advances about every 12 seconds. So a restriction window measured in blocks is far longer in wall-clock time than it first appears.
3. Your buys
There are two ways to get your allocation, and they suit different launches:
| Approach | How it works | Best when |
|---|---|---|
| Buy inside the launch call | The whole allocation is acquired by the creator buy inside launchToken, in the launch block, then distributed to your wallets. | You want a guaranteed uncontested entry — nobody else can transact in that block. |
| One router multicall | Many exactInputSingle swaps batched into a single SwapRouter02 multicall, each paying a different wallet. All land or all revert. | You want the tokens to arrive directly in separate wallets without a distribution step afterwards. |
What it costs
Three separate things, often confused with each other:
- The Pons launch fee — charged by the launchpad, not by us.
- Gas — negligible on this chain, but never zero.
- Your own buys — this is not a cost so much as a position. It is ETH you are converting into your own token.
BundleZeus charges 0.69% per trade on top: on the bundled buys only if the launch actually lands, and on sells. If the launch does not land, there is nothing to charge for. Simulation is free and unlimited.
Mistakes that cost real money
- Skipping the testnet run. The testnet is a complete copy of the flow. Every configuration mistake you would make on mainnet, you make there instead, for free.
- Buying with identical amounts from every wallet. Twenty wallets each spending exactly 0.05 ETH in the same block is a signature, not a crowd. Vary the sizes.
- Funding every buyer wallet from the same source in one sweep. On-chain clustering tools read funding graphs. Wallets funded in a visible star pattern from one address are trivially linked back together.
- Forgetting the exit. Selling everything at once undoes the point of having spread the buys in the first place.
- Trusting a gas estimate. Orbit chains mis-estimate gas on complex calls often enough that any serious tooling needs a fallback.
Do it with BundleZeus
The launch wizard walks the whole sequence — configure, generate and fund wallets, simulate, fire — and handles the atomic-buy mechanics described above for you. Practice mode runs the identical flow on the testnet at no cost.
