Liftoff
When a buy fills the curve, liftoff happens inside that same transaction:
- If your buy was larger than what was left, you only pay for the remaining tokens — the rest is refunded.
- A 3 % graduation fee is taken from the native raised.
- The rest of the native and the matching amount of tokens go into a new TzeroSwap pool at exactly the curve's final price — no jump.
- Any reserved tokens not needed for that price are sent to
0x…dEaD(burned). - The pool's LP tokens are sent to
0x…dEaD: the liquidity can never be withdrawn.
After liftoff the mission's page switches to Trading on TzeroSwap and the trade panel routes through the TzeroSwap router. A buy that may trigger liftoff is sent with a 3,000,000 gas limit by the app.
Atomic Liquidity Migration & Permanent LP Burn
Liftoff is the graduation milestone on TZero Fun (Tzer0 fun) where a token transitions from its initial bonding curve to a full decentralized exchange pool on TzeroSwap.
What Happens Inside the Liftoff Transaction
- Curve Closure: The bonding curve reaches 100% fuel (`2.0 ETH` net reserve) and permanently disables further curve buys or sells.
- Liquidity Pairing: After deducting the
0.05 ETHgraduation fee,1.95 ETHis wrapped into WETH and paired with the reserved token supply in a new TzeroSwap pair. - Irreversible LP Burn: All minted TzeroSwap LP tokens are transferred directly to
0x000000000000000000000000000000000000dEaDin the same transaction, guaranteeing permanent market liquidity.
