One fixed supply of 1,000,000,000, all of it in the pool from the first block. Liquidity can never be pulled. You choose the fee and who it pays.
The platform keeps 25% of this fee (70% developer · 30% Votive holders). Your side is split three ways:
Leave empty and it all goes to you. Up to 5 shareholders. Each share can later be sold as fee-share units.
Pick one of your campaigns and add its fee address as a shareholder. Those fees can only fund that campaign.
