Protocol Overview: What is TanaFun.family?
TanaFun.family is the decentralized fair-launch token platform deployed on
Robinhood Chain (EVM L2, Chain ID: 4663). The protocol empowers creators and communities to deploy tokens in seconds with zero upfront liquidity, trade on continuous mathematical bonding curves, and automatically graduate to permanent DEX liquidity pools.
100% Fair Launch
Zero presales, zero insider allocations. Everyone buys from the open bonding curve on equal terms.
Automated Liquidity
Mathematical bonding curve provides instant buy and sell liquidity from the very first transaction.
Permanent DEX Lock
When market cap reaches $69,000, $12,000 liquidity is auto-deposited into Robinhood DEX & LP tokens are burned forever.
Key Features & Differentiators
| Feature | Legacy Launchpads | TanaFun on Robinhood Chain |
|---|---|---|
| Initial Liquidity | Required ($5k–$20k) | $0 Needed (Bonding Curve Genesis) |
| Team Allocations | 15–30% Insider Pre-mines | 0% (100% Fair Genesis) |
| Transaction Speed | 12–45 seconds | ~1.2 seconds (Robinhood L2) |
| Gas Fee per Trade | $2.00–$25.00 | < $0.001 (Micro-Gas) |
| DEX Graduation | Manual / Vulnerable to Dev Rugs | Automated & 100% LP Burned |
Bonding Curve Mathematical Formula
Every token deployed on TanaFun operates on a continuous, deterministic bonding curve. The price per token increases monotonically as the circulating supply increases, governed by the mathematical function:
P(S) = k × S2 + P0
Where:
P(S)= Instantaneous price in RH-ETH at circulating supplyS.S= Total tokens purchased from the bonding curve (0 to 800,000,000 tokens).k= Constant curve steepness multiplier (1.428 × 10-17).P0= Genesis floor price (0.000000028 RH-ETH).
Robinhood DEX Graduation & LP Burn
When a token reaches 100% of its bonding curve (equivalent to a $69,000 Market Cap), the smart contract automatically executes the graduation sequence:
Curve Finalization
Bonding curve trading is finalized. The final pool balance of accumulated RH-ETH and 200M reserved tokens are locked.
Automated Pool Creation
The contract deposits $12,000 in RH-ETH along with 200,000,000 tokens into a new Robinhood DEX liquidity pool.
Permanent LP Token Burn
100% of liquidity provider (LP) tokens are sent to the dead address (0x0000...dead), rendering the liquidity permanent and unruggable forever.
$TANAFUN Platform Tokenomics
$TANAFUN is the native utility, fee-capture, and governance token of the launchpad platform.
50% Platform Fee Buyback & Burn Engine
A 1% protocol fee is levied on bonding curve trades. This fee is automatically split:
50% $TANAFUN Buyback & Burn
Automatically executes market purchases of $TANAFUN and sends them to the dead burn address.
50% Ecosystem & Liquidity Rewards
Distributed to top creators, platform development, and decentralized liquidity providers.
How to Launch a Token (Step-by-Step)
Deploying a token on Robinhood Chain takes less than 10 seconds using our Launchpad Studio:
- Connect Wallet: Connect your Robinhood Wallet, MetaMask, Phantom, or Coinbase Wallet.
- Set Name & Ticker: Choose a recognizable token name and symbol (e.g., Robin Hood Cat / $HOODCAT).
- Write Lore: Add your meme description, community backstory, and social links (X, Telegram).
- Optional Dev Buy: Enter an initial purchase amount if you wish to hold the first tokens on the curve.
- Deploy: Click "Launch Token on Robinhood Chain" and confirm the small gas transaction.

Smart Contracts & Security Architecture
TanaFunFactory.sol
Deploys isolated bonding curve pools and verified ERC-20 token contracts in a single atomic transaction.
BondingCurvePool.sol
Manages mathematical buying and selling, slippage protection, and reserves management.
LiquidityMigrator.sol
Automates the trustless transfer of liquidity to Robinhood DEX and burns LP tokens upon graduation.
Launchpad API & SDK Reference
import { TanaFunClient } from "@tanafun/sdk";
const client = new TanaFunClient({
chainId: 4663,
rpcUrl: "https://rpc.robinhoodchain.org"
});
// Deploy a new token on Robinhood Chain
const token = await client.deployToken({
name: "Robin Hood Cat",
ticker: "HOODCAT",
description: "Flagship cat meme on Robinhood Chain",
initialBuy: "0.025" // in RH-ETH
});
console.log(`Token Deployed at: ${token.address}`);
console.log(`Bonding Curve Pool: ${token.curveAddress}`);Frequently Asked Questions
Can developers withdraw liquidity before graduation?
No. Bonding curve contracts do not allow any liquidity extraction. All funds are mathematically locked until DEX graduation.
What fees are charged by TanaFun?
A standard 1% fee on bonding curve trades (0.5% buyback and burn, 0.5% LP ecosystem rewards). Token deployment requires only standard network gas.
Are token contracts verified?
Yes. All deployed tokens use standardized, audited, and open-source ERC-20 bytecode verified automatically on Robinscan.
What happens if a token doesn't reach 100% curve?
Holders can sell their tokens back to the bonding curve at any time. The contract always maintains mathematical reserve liquidity.
