Tech works well
UPDATE: $KLN dipped, so I hit Undo and got the full 0.3 $ETH back. Rebought lower with a fresh 1h window: 2,775 to 4,233 $KLN. The premium was a small price to pay! Nothing like that on any other launchpad. Token purchase insurance is real and works with: @kolan_protocol
For anyone asking for details about the contracts that will be released soon, these are improvements to the launchpad, particularly related to technical details. No tokens that have already been issued will be affected.
Kolan continues to grow, and we can make changes along the way to ensure we have the best product.
How Kolan windows work
A window is a purchase you can still take back. You pay a premium in ETH, the premium decides how long the window lasts, and until it ends you can undo the purchase and get back every wei you spent on the tokens.
What a window is
Without a window, buying KLN is a plain Uniswap swap, final the moment it lands. With a window, you send the ETH to spend on tokens, the 1% tax, and a premium. Think of it as an option: the right to hand the purchase back at your entry price, with the premium as its price.
How long it lasts and what it costs
The premium alone decides the length of a window. 0.05 ETH buys six hours, and twice the premium buys twice the time, whatever the size of the purchase: 0.2 ETH buys a full day. A window lasts at least 30 minutes and at most 7 days, and any premium beyond 7 days is refunded.
The premium can be at most 30% of the ETH spent on tokens, so long windows need larger purchases. A 30-minute window needs a purchase of at least 0.014 ETH, and six hours need about 0.167 ETH.
The tax and the premium are kept whatever happens. Only the ETH spent on the tokens can come back.
Opening: a hole in the pool
When you buy with a window, the Kolan hook takes out of the Uniswap pool exactly the tokens a swap of your ETH would buy, and holds them with your ETH. This leaves a hole in the pool's liquidity.
A buyer crosses the hole for free and pays the price after it, as if your purchase had happened, so nobody gets your tokens at your price. A seller cannot reach your ETH, because it is not in the pool.
Closing: undo or keep
Undo is yours alone, and only before the expiry. Every wei of the ETH you spent on the tokens comes back in the same transaction, and the tokens go back into the pool.
Keep can be done by you at any time, or by anyone once the window has run out, and the tokens still only go to you. They land in your wallet and your ETH goes into the pool, as if you had just bought.
A purchase is always either refunded or delivered, never both. Tokens and ETH always return to the pool, into the hole or next to the current price depending on where the price has moved. Nothing is burned in their place.
Where the premium goes
The premium never goes to the dev. When the window closes, undone or kept, it buys tokens from the pool and those tokens are burned. The supply only goes down, and every window pushes the price up a little when it ends.
What nothing can change
The expiry is stored with the purchase, and nothing anyone does afterwards can shorten it. While the window is open, nobody but you can reach its ETH: the hook has no owner, no admin key and no upgrade path. It also tracks the ETH and tokens it holds for open windows, and checks after every operation that it still holds them.
