One-Click Wallet Integration
1-Click Google Smart Accounts (Web3Auth MPC)
Traditional Web3 onboarding requires installing extensions, backing up 12-word seed phrases, and managing recovery. Hoot solves this completely through non-custodial Multi-Party Computation (MPC).
Security & Architecture
Neither Hoot nor Google ever possesses your private key. The key is mathematically divided into independent cryptographic shares via Shamir's Secret Sharing across the decentralized Web3Auth node network.
Users can trade from mobile Safari, Chrome, Telegram in-app browsers, or desktop. If you lose your phone, simply logging back into your Google account securely restores full access to your funds.
Private Key Portability
How Trading Works: Buys, Sells & Slippage
Trading on Hoot feels like an exchange, but settles directly against an audited bonding curve smart contract with no counterparty risk.
Buying & Selling Mechanics
Buying Tokens
When you submit a Buy order, you send native ETH into the token's bonding curve. The contract calculates the exact tokens you receive based on current reserve depth, deducts a transparent 1.0% protocol fee, transfers the tokens to your wallet, and adjusts the spot price upward.
Selling Tokens
When you sell, you approve and return your tokens to the curve contract. The curve burns or absorbs the tokens, calculates the exact ETH refund, deducts the 1.0% fee, and sends native ETH directly back to your wallet. You can sell at any time, even if other traders are inactive!
Slippage & MEV Safeguards
Slippage & Anti-Frontrunning
Slippage is the difference between expected price and execution price. On high-volume momentum runs, setting slippage to 2.5% to 4.0% prevents transactions from reverting. Hoot curves include block deadline protection (deadline) to guard against stale transaction exploitation.
20% Instant On-Chain Referral System
Earn perpetual native ETH and quote token commissions from every swap executed by your referred traders.
Instant Payout Structure
Every user receives an instant personal referral link. Whenever anyone buys or sells tokens through your link, 20% of the 1% protocol fee is automatically sent to your address in that exact transaction.
Earned fees across ETH, USDG, and stock tokens accumulate safely in the on-chain fee escrow contract. Batch-claim all accumulated assets in 1 click at any time with zero minimums.
Zero Claim Minimums
The Bonding Curve Engine: Virtual CPMM Formula
Hoot implements a Virtual Constant Product Market Maker (vCPMM) invariant. Virtual reserves bootstrap early price discovery without requiring initial creator capital.
Interactive Bonding Curve & Price Dynamics Live Vector Simulation
Constant Product Equation
V_eth = 2.0 ETH($2 \times 10^{18}$ wei) — Virtual ETH offset to smooth starting volatilityV_tokens = 1,000,000,000($10^9 \times 10^{18}$ wei) — Virtual token supplyk = 2.0 × 10¹⁸ × 10²⁷ = 2.0 × 10⁴⁵— Constant invariant preserved across all non-fee state transitionsTARGET_ETH = 8.00 ETH— Real reserves required for 100% curve graduation
Exact Token Output Calculation (Buy Function)
Given net ETH deposited ΔETH_net = msg.value - protocolFee:
Exact ETH Return Calculation (Sell Function)
DEX Graduation & Permanent LP Burn
When a token reaches 8.00 real ETH, the bonding curve automatically finishes and graduates to the Robinhood DEX (Uniswap v4 Hook Pool).

Graduation Bounties & Distributions
Paid automatically to the token creator's wallet upon reaching graduation threshold.
100% of remaining curve reserves paired with 200M reserved tokens; LP tokens burned forever.
Unbreakable LP Burn Guarantee
migrateLiquidity(), the LP recipient parameter passed to the canonical Uniswap v4 Hook Pool is hardcoded to:

- Smooth Gestures: Native mouse wheel zooming (40% to 250%) and drag-to-pan on mobile & desktop.
Verified Smart Contracts (Robinhood Chain L2)
All core protocol contracts are compiled with Solidity 0.8.24, deployed natively to Robinhood Chain L2 Mainnet (Chain ID 4663), and verified on Blockscout explorer.
Official Mainnet Contract Registry
Rug-Proof Security Model
Hoot smart contracts are engineered with immutable rules to eliminate rug pulls, team dumps, and malicious administrative backdoors.
Security Architecture & Protections
✓ Checks-Effects-Interactions (CEI)
Every curve state variable (realTokenReserve, realQuoteReserve) updates strictly before external token or ETH transfers occur. OpenZeppelin ReentrancyGuard is enforced across all state mutating functions.
✓ 100% Locked Liquidity (Burned LP)
Upon bonding curve graduation, 100% of collected quote assets and 200,000,000 reserved tokens are deposited to Robinhood Swap AMM. The resulting LP tokens are minted directly to address(0) (burned forever). Liquidity can never be pulled.
✓ Zero Team Pre-Mine or Insider Allocation
Token creators receive 0 free tokens upon deployment. 80% is allocated to the public curve and 20% to the DEX migration seed. If creators want tokens, they must buy them on the fair bonding curve like every other trader.
✓ Immutable Token Supply (No Minting)
All launched tokens are standard non-upgradeable ERC-20 tokens with a fixed 1,000,000,000 supply (18 decimals). There are no mint functions, blacklist switches, pause gates, or transfer taxes.
✓ Pull-Based Reentrancy-Safe Referral Engine
Referral fee distributions execute with isolated gas bounds and safe fallbacks. If an affiliate receiver address is a malicious contract designed to revert ETH transfers, the swap does not revert; the affiliate reward safely falls back to protocol custody.
✓ Anti-Frontrunning Slippage & Deadlines
Every swap transaction enforces minimum tokens received (minTokensExpected) and a block timestamp deadline. Validators cannot delay transactions in the mempool to execute stale or manipulated trades.
Frequently Asked Questions
Essential answers to the most common questions regarding Hoot Protocol on Robinhood Chain L2 Mainnet.
Protocol & Trading FAQ
What is Hoot on Robinhood Chain L2? +
Hoot is a decentralized fair-launch token launchpad and virtual bonding curve AMM natively deployed on Robinhood Chain L2 Mainnet (Chain ID 4663). It enables users to deploy and trade tokens paired against native ETH, Robinhood USDG stablecoins, or tokenized stocks like Tesla ($TSLA) and NVIDIA ($NVDA).
Can the token creator pull liquidity or dump? +
No. Creators receive 0 free tokens at launch. 800M tokens are locked on the bonding curve, and 200M are reserved for the Uniswap v4 liquidity pool. Once 800M tokens are sold, liquidity is deposited into Robinhood Swap and the LP tokens are burned forever to address(0). It is mathematically impossible for anyone to pull liquidity.
How are trading fees distributed? +
Every trade on the bonding curve incurs a flat 1.0% swap fee. It is split automatically on-chain: 50% (0.50%) to the Token Creator, 30% (0.30%) to the Protocol Treasury, and 20% (0.20%) to the HootV2BuybackVault for continuous market buyback and burns.
What happens when a token graduates? +
When 100% of the 800M tokens on the curve are purchased, the contract automatically executes graduation. 100% of accumulated quote assets and 200M tokens are migrated directly to the Robinhood Swap DEX (Uniswap v4 Hook Pool), and LP tokens are permanently burned. All subsequent trades execute on the DEX via HootSwapRouter.
How do stock-paired memecoins work ($TSLA & $NVDA)? +
Instead of pairing against ETH or USD, tokens can be deployed paired directly against tokenized stocks (e.g. 50.0 TSLA or 70.0 NVDA). Traders buy and sell the curve using tokenized shares, and all profits are settled directly in tokenized equity on Robinhood Chain L2.
