Overview
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.
Mission Lifecycle Architecture on TZero Fun
On TZero Fun (Tzer0 fun), every token follows a deterministic three-stage lifecycle enforced entirely by immutable smart contracts without human intermediaries or off-chain keepers:
Stage 1: Atomic Token Creation (T-0)
A creator deploys a new mission by calling launch(name, symbol, uri) on the TzeroLaunchpad contract. The contract mints 1,000,000,000 tokens, places 800,000,000 on the bonding curve, reserves 200,000,000 for liftoff liquidity, and optionally executes the creator's first buy in the exact same transaction.
Stage 2: Bonding Curve Fuel Accumulation
Traders buy and sell the token directly against the bonding curve. Each trade pays a 1% fee (split 50% creator / 20% $T0 stakers / 30% protocol), while net ETH purchases fill the mission's fuel gauge toward the 2.0 ETH graduation target.
Stage 3: Liftoff to TzeroSwap AMM
The trade that reaches 2.0 ETH net reserve automatically graduates the mission, pairs the remaining 200,000,000 tokens with the ETH reserve in a TzeroSwap pool, and burns the LP shares forever.
