Robinhood Chain meme launchpad docs
Launchpad and bonding curve
Launchpad creates the token market, records positions, collects fees, and closes the curve at graduation.
0.0001 ETH
Virtual curve + Robin Tax
4 ETH graduation
Farming + V3 LP
Create a token
Create from Launch with a name, symbol, image, and optional project profile. The contract stores the creator, graduation target, deadline, and token economics for that token.
- The production creation fee is 0.0001 ETH.
- A token must be active and the Launchpad must be activated before trading is available.
- The token creator can optionally attach a website, X profile, description, and creator name.
Virtual constant-product curve
Pricing uses virtual constant-product reserves, so a new market starts above zero and the price rises as the real reserve grows. The curve sells 800M tokens; 200M remain for graduation liquidity.
- Buy output is calculated from the net WETH amount after the dynamic Robin Tax.
- Sell output is calculated from the exact token amount supplied and then reduced by sell taxes.
- All curve math uses integer-safe rounding: buys round output down and required costs up.
- The final buy can be partially accepted. If the requested ETH is larger than the remaining curve capacity, the contract fills the remaining tokens, refunds the unused ETH, and graduates the token.
Trading parameters and protection
Buy uses maxTokenPrice; sell uses minTokenPrice. The frontend derives these limits from current chain state, while the contract validates the final execution price.
- A single buy is limited by the on-chain maximum token amount.
- Buy and sell methods are non-reentrant and validate token status, balances, deadlines, and curve capacity.
- The referral account is optional; a zero address or self-referral uses the normal fee path.
Dynamic Robin Tax and fee routing
Robin Tax follows graduation progress. Referral rewards are carved from the actual trade fee first; the default split is 5% to the referrer and 5% to the trader, with VIP splits limited to a 10%-30% combined rate.
Graduation and the next market
The final buy can trigger graduation atomically: curve trading closes, Farming is created, holder allocations enter the claim-and-stake path, and the remaining tokens plus ETH seed a Uniswap V3 position at the graduation price.
- The production graduation target is 4 ETH.
- The production graduation window is 30 days.
- After graduation, users use Farming to claim and stake, and use Swap for secondary-market trading.
