hood.fun whitepaper

hood.fun lets anyone launch a token in one transaction. Every token starts trading immediately on a bonding curve — a smart contract that quotes a price from its own reserves — with no presale, no team allocation, and no way for the deployer to pull liquidity. When a token's curve sells out, its liquidity migrates to official Uniswap v3 and the position is locked forever in a locker with no withdraw function — the pool can never be rugged, and its trading fees keep paying the creator for life.

The protocol is a single audited-pattern contract deployed on Robinhood Chain, an Arbitrum-stack Ethereum L2. Gas is paid in ETH. Nothing about a launch depends on hood.fun staying online — the contracts run on their own.

Each token uses a constant-product curve with virtual reserves — the same x · y = k math that powers Uniswap, seeded so price starts low and rises smoothly as tokens are bought. Buyers pay ETH into the curve and receive tokens; sellers return tokens for ETH. Price is always a deterministic function of how much of the curve supply has been sold — early buyers pay less, later buyers pay more.

Because pricing is virtual-reserve based, there is deep, continuous liquidity from the very first trade — no empty order books, no waiting for a market maker.

Creators choose their own trade feeat launch — from 1% to 5% — charged on every buy and sell on the curve. This is hood.fun's core difference: a creator can run a low 1% fee to attract traders, or a higher fee to earn more per trade.

Creators keep 50% of every feetheir token generates; the protocol takes the other 50%. Creator earnings accrue on-chain per token and are claimable at any time from the creator's profile.

Fees don't stop at graduation.The Uniswap v3 pool every coin migrates into charges a 1% fee on each swap. Because the pool's liquidity position stays locked in the hood.fun Locker (rather than being burned), it keeps earning that fee — and every collection is split 50/50 between the creator and the protocol, forever. Anyone can trigger a collection; nobody can redirect it. If other people later add their own liquidity to the pool, they earn the fee share of their own positions — the locked position's earnings continue unchanged.

When the last curve token is sold, the token graduates. Anyone can then call the permissionless migrate function — it pairs the raised ETH (minus the migration fee) with the 200M reserved tokens in a 1% fee pool on the official Uniswap v3 deployment on Robinhood Chain, then locks the entire liquidity position in the hood.fun Liquidity Locker.

The locker has no withdraw function, no owner, and no admin— the code that could move the liquidity simply does not exist, so no team, no deployer, and no key compromise can ever pull it. Unlike burning LP, locking keeps the position alive: it earns the pool's 1% swap fee forever, paid out 50/50 to the creator and the protocol. This is the same locked-position model that secures the largest v3 launchpads. Migration is idempotent and safe against a pre-existing pool, so it cannot be manipulated by front-running — a class of exploit that has hit other EVM launchpads.

hood.fun is fully non-custodial. Users sign their own transactions with their own wallets; the platform never signs, holds, or routes user funds.The only privileged role is the contract owner, which can do exactly two things: adjust fee configuration within hard-coded caps, and withdraw the protocol's accrued fee share. It cannot touch curves, balances, or liquidity.

Additional protections built into the contract:

• Tokens are non-transferable outside the curve until graduation, closing pre-seeded-pair exploits.
• Slippage bounds (minimum-out) enforced on every trade.
• Reentrancy guards and checks-effects-interactions throughout.
• A launch snipe-guard caps any single wallet during the first blocks after creation.
• Fee caps enforced on-chain — no fee can exceed the coded maximum.

ETH conservation and solvency are verified by an invariant-fuzzing test suite: across any sequence of trades, graduations, and claims, the contract always holds exactly what it owes — to the wei.

hood.fun is experimental software for launching and trading memecoins. Memecoins are highly volatile and most go to zero. Nothing on this site is financial advice. Do your own research, and never risk more than you can afford to lose.
