How Tzero works, from launch to liftoff — straight from the contracts.

TZero Fun Protocol Documentation

Tzero is the launchpad for Zero, LayerZero's new L1. Anyone can launch a token — a mission — in one transaction. A mission trades on a bonding curve (its fuel) until the curve is full; then it lifts off: its liquidity moves to TzeroSwap, the first DEX on Zero, and is locked forever.

  • Fixed supply, no owner. Every mission is a plain ERC-20 with 1,000,000,000 tokens minted once. No mint function, no owner, no pause, no blacklist, no transfer tax.
  • Fair start. The creator can make the first buy in the same transaction as the launch, so no bot can buy before them.
  • Creators get paid. 50 % of every trading fee on a mission goes to its creator — on the curve and after liftoff, forever.
  • $T0 holders get paid. 20 % of every trading fee goes to $T0 stakers.
  • Liquidity is locked by code. At liftoff the LP tokens are sent to 0x…dEaD.

Zero mainnet is expected in Q4 2026. Until Zero opens a testnet, Tzero runs on Base Sepolia with the same contracts.

Complete Guide to TZero Fun (Tzer0 fun)

Welcome to the official technical documentation for TZero Fun (also known as Tzer0 fun). TZero Fun is an end-to-end token launchpad and decentralized exchange protocol engineered for Zero (LayerZero's Layer 1 blockchain) and operating live in Season 0 Pre-flight on Base Sepolia (Chain ID 84532).

Core Protocol Pillars

  • Immutable ERC-20 Token Standard: Every mission deploys an unowned, fixed-supply 1,000,000,000 ERC-20 token contract with zero mint, pause, or blacklist capabilities.
  • Deterministic Constant-Product Bonding Curve: 800,000,000 tokens trade along a transparent curve until 2.0 ETH of net reserve fuel is accumulated.
  • Automatic TzeroSwap Migration: At 100% fuel, liquidity moves atomically to TzeroSwap and LP tokens are permanently burned to 0x000000000000000000000000000000000000dEaD.
  • Perpetual On-Chain Fee Sharing: The 1% trading fee is split 50% to the token creator, 20% to $T0 stakers, and 30% to the protocol across both curve and DEX trading.
