# What is Omni.fun

> The first omnichain memecoin launchpad — powered by LayerZero V2

# Omni.fun

Omni.fun is a multichain memecoin launchpad deployed on **Base** with cross-chain infrastructure spanning **7 EVM chains + Solana**. Every token launched on Omni.fun is automatically a LayerZero V2 OFT — tradeable, bridgeable, and launchable from any supported chain.

## What Makes It Different

A user on Solana can launch a token that deploys on Base. A trader on Arbitrum can buy it with native ETH. An AI agent can self-launch via API and trade cross-chain autonomously. All of this is powered by **LayerZero messaging at every layer**.

## The Numbers

## Token Lifecycle

Every token on Omni.fun follows a deterministic lifecycle:

1. **Launch** — One transaction deploys an ERC-20 token and bonding curve on Base. Auto-registers across all routing infrastructure.
2. **Bonding Curve Trading** — Deterministic linear pricing. Users buy and sell from any supported chain.
3. **Graduation** — At a \$69,000 USDC market cap, the token automatically graduates to a Uniswap V3 pool. LP is permanently locked in a rug-proof vault — no admin keys, no withdrawal, no exceptions.
4. **Post-Graduation** — All cross-chain trading routes seamlessly to Uniswap V3 instead of the bonding curve. No user action required.

## LayerZero Is the Backbone

LayerZero V2 powers four critical flows in the protocol:

* **Cross-chain buying** — `_lzReceive()` on CCBuyerV3 processes buy requests from any chain and auto-bridges tokens back via OFT
* **Cross-chain selling** — OFT burn on remote chain → LZ message → sell on Base → USDC return
* **Cross-chain launching** — RemoteLauncher/TokenLauncher sends LZ message → CrossChainLauncher deploys token on Base
* **OFT infrastructure** — Single-transaction deployment of OFTAdapter + 6 remote OmniOFTs via LZ messages to OFTFactoryRemote contracts

Every cross-chain trade generates LayerZero messages. Every token bridge is an OFT transfer. Every remote launch is an LZ payload. The protocol's transaction volume maps directly to LZ message volume.
