HoodLaunch — Documentation

HoodLaunch is a permissionless token launchpad on Robinhood Chain. Anyone can create a token in a single transaction; it starts trading immediately on a bonding curve with no presale, no team allocation, and no insider rounds. When the curve raises its target, the token graduates automatically: liquidity is deposited into a public Uniswap market and the LP tokens are burned, locking the liquidity forever.

Pricing is deterministic and fully on-chain. Every participant — including the creator — buys from the same curve at the same rules.

Traditional token launches concentrate supply with insiders before the public can buy: presales, team allocations, and seed rounds mean early holders can dump on later ones, and hand-seeded liquidity can be pulled at any time.

A bonding curve replaces all of that with mechanical price discovery. The contract itself is the market maker: price rises as tokens are bought and falls as they are sold, following a public formula that nobody — not the creator, not the protocol — can override. Combined with burned liquidity at graduation, this removes the two classic rug-pull vectors: insider supply and removable liquidity.

HoodLaunch uses a constant-product curve (x · y = k) with virtual reserves. The launchpad contract holds the token reserve and tracks a virtual ETH reserve; buys add ETH and remove tokens, sells do the reverse. Each purchase raises the price and each sale lowers it — smoothly and predictably, with no order book and no gaps.

Milestones are denominated in USD and snapshotted to ETH at the moment a token is created. Every token starts at a $4,000 virtual market cap and graduates once $9,300 (in creation-time ETH terms) has been raised — a graduation market cap of roughly $44,000. Later ETH price moves don't shift a token's milestones.

Both quotes (quoteBuy / quoteSell) are exposed as view functions, and every trade accepts a slippage bound.

Each launch chooses a total supply between 10,000 and 1,000,000,000 tokens (default 1B). The allocation is fixed:

• 70% — bonding curve. Sold through the curve between launch and graduation.
• 30% — liquidity reserve. Held by the launchpad and deposited into the Uniswap pool at graduation.

Market-cap milestones are invariant to the supply choice: every token starts at $4,000 and graduates at ≈ $44,000 regardless of whether it has ten thousand or a billion units. There is no mint function, no pause, and no admin control over any launched token.

Launches can include an optional initial buy — the creator's own first purchase, executed in the same transaction at the same curve price available to everyone else.

When a token's curve reaches its $9,300 target (the final buy is clipped to the target and any excess ETH refunded), graduation runs automatically inside that same transaction:

• $9,000 of the raise is paired with the 300M-equivalent (30%) liquidity reserve and deposited into a Uniswap V2 pool.
• The liquidity is added directly to the pair — not through the router — so no one can capture or block the migration.
• LP tokens are sent to the burn address — 100% of the liquidity is locked forever. A graduated token can never have its liquidity removed.
• The remaining $300 funds the protocol treasury.

After graduation the bonding curve closes permanently and all trading happens on the public Uniswap market.

HoodLaunch charges a dynamic trade fee that falls as a token's market cap grows — on every buy and every sell, before and after graduation. New tokens pay 0.95% in total; the most mature tokens pay just 0.095%. Early trading funds the creator and the protocol while the token is finding its feet; friction all but disappears once it has matured.

The tier is read from the token's live market cap, denominated in ETH — from the bonding curve's virtual reserves before graduation and from the Uniswap pool's reserves after. Every trade is charged the tier in force at that moment:

• Creator rewards are paid to the token's fee address. The fee address defaults to the wallet that launches the token but can be set to any address at creation. Curve fees are claimable in ETH from the token page; post-graduation fees are paid out automatically.
• After graduation, 20% of the creator share is reinvested into the liquidity pool. Each time accumulated fees are paid out, a fifth of the creator's ETH is wrapped and donated to the token's Uniswap pair. Because the LP is 100% burned, the donation is permanent — every payout deepens the token's locked liquidity. The creator receives the remaining 80%: the table above shows the gross creator share, so a graduated creator's effective take is 80% of that column (e.g. 0.304% of a 0.38% tier). Before graduation the creator share is paid in full.
• The protocol share is paid to the protocol treasury.

Fees are always paid in ETH. On the curve they are taken from the ETH directly; on Uniswap they are collected in tokens on each pair trade and auto-swapped to ETH once the accumulated amount is worth about $5 (at the token's creation-time snapshot). The swap panel always shows the exact fee in force for the token you're trading.

A token's image, description, and social links (X, Telegram, Discord, website) are stored on-chain in the token contract at creation. Uploaded images are compressed in the browser and embedded as data URIs, so a token's identity needs no external hosting to survive.

All properties — name, symbol, total supply, fee recipient, and metadata — are fixed at creation. Nothing about a launched token can be edited afterwards, by anyone.

• Minimal admin surface.The launchpad has no upgrade path, and launched tokens have no mint or pause. The single admin power is fee-recipient reassignment: the protocol admin can redirect a token's creator fee share to a different wallet. It cannot touch balances, liquidity, supply, or trading — the burned LP and the curve math are untouchable. This authority is fixed at deployment and enforced on-chain (every other caller reverts).
• Per-curve accounting.Each token's reserves are tracked independently; sells can never withdraw more ETH than that token's curve holds.
• Reentrancy guardson all state-changing entry points, and pull-based fee claims so a malicious recipient can't block trading.
• Front-run-resistant migration. Graduation deposits liquidity directly into the pair, tolerating pre-seeded pools, and the final buy is clipped with the excess refunded.
• Slippage bounds on every curve trade.
• Anti-farmer protection (optional, 0–30 days, chosen at launch): during the window, liquidity cannot be added to Uniswap V3 pools of the token, preventing fee farmers from routing volume around the trade fee and the canonical burned-liquidity market.
• The full lifecycle — launches, trades, fee accrual, graduation with burned LP, post-graduation fee swaps — is covered by an adversarial end-to-end test suite run against the canonical Uniswap V2 contracts.

The contracts are open source and unaudited — review them before committing meaningful value.

HoodLaunch runs on Robinhood Chain, an Ethereum L2 with ETH as the gas token, and uses the official Uniswap V2 deployment for graduation liquidity. Details for the currently selected network:

Tokens launched on HoodLaunch are not investments and carry no promise of value, utility, or return. Prices set by bonding curves and AMMs are volatile; you can lose everything you spend. Burned liquidity prevents liquidity removal but does not prevent prices from going to zero. HoodLaunch is unaffiliated with Robinhood Markets or Uniswap Labs.
