Campaigns
A campaign gathers ETH toward a target before the token exists. Hit the target and the token launches with the whole raise buying in first, so every backer pays the same price. Miss it and every backer takes their ETH back in full.
Campaigns open once the campaign contract is live.
Set a target
The creator picks a target between 0.01 and 5 ETH and a closing time between one day and thirty days.
Backers chip in
Anyone can send ETH to the campaign. The contract holds it and nobody, the creator included, can take it out early.
Target hit
The token launches and the whole raise buys from the fresh pool in the same transaction. Each backer claims a share in proportion to what they sent.
Target missed
When the closing time passes without the target, every backer presses refund and gets back exactly what they sent.
A campaign pays the same costs as any launch: the launch fee and 5% of the ETH used to buy, plus gas. Big raises move the price a lot, because the whole raise buys from a pool that opens small.
