Testnet data: tokens and amounts have no real-money value.
The opening tax
Checked 2026-11-08. Things can change before mainnet.
Each new launch fixes a base tax of 1%, 2% or 3% when it is created.
For the first 20 seconds, curve buys pay a rate that falls from 99% down to that base tax. Sells and the creator's own opening buy don't pay this surcharge.
We measured the rate on testnet on 2026-11-02: rate = base + (99% - base) × (20 - t) / 20, where t is the number of seconds since launch.
