# BigPump.ai

> BigPump.ai is an NFT + memecoin launchpad on Robinhood Chain (an Ethereum Layer‑2, chainId 4663). Anyone can create a meme token in seconds, trade it on a bonding curve, and — once it fills — automatically graduate it to Uniswap V2 with liquidity locked. BigPump's signature feature is the ERC‑405 hybrid asset: every token is bound 1:1,000,000 to an on‑chain NFT, so holders own both a fungible token and a collectible that move together.

## What makes BigPump different

- **Runs on Robinhood Chain (chainId 4663)** — a fast, low‑fee Ethereum L2 built on Arbitrum Orbit technology, where gas is paid in ETH.
- **ERC‑405 hybrid asset** — token and NFT are two faces of the same value; transferring one moves the other, at a fixed 1:1,000,000 ratio. Gas cost stays close to a plain ERC‑20 transfer.
- **Fair bonding‑curve launch** — no presale, no team allocation. Price rises along a curve as people buy.
- **Automatic graduation to Uniswap V2** — when the raise target is reached, liquidity is added to Uniswap V2 and the LP is permanently burned (sent to the dead address). Anti‑grief graduation mints liquidity directly to the pair, so a graduating token cannot be locked by a poisoned pool.
- **Optional tax + dividend rewards** — creators can enable a transfer tax split across treasury, burn, buyback‑and‑liquidity, and holder dividends. Dividends accrue to holders and can be claimed. Tax applies only after graduation (on DEX trades), never on the internal bonding curve.
- **On‑page trading** — buy and sell both before and after graduation without leaving the site.

## How to launch a meme coin on BigPump

1. Connect a wallet on Robinhood Chain (chainId 4663).
2. Enter name, ticker, description, and image (or generate art with AI).
3. Optionally enable tax/dividend rewards and set the split.
4. Optionally add a small initial buy.
5. Confirm — the token deploys and starts trading on its bonding curve immediately.
6. As people buy and the curve fills, the token graduates to Uniswap V2 automatically.
