What a launch costs

No launch fee: network fees plus the KAS the token’s cells carry.

Kasseal charges no launch fee. The Create screen’s summary card, What you’ll pay, lists everything that leaves your wallet:

LineWhat it is
Signature 1 fee (est.)Network fee of the first transaction.
Signature 2 fee (est.)Network fee of the second transaction.
Cell depositsKAS carried by the curve cell (5 KAS) and the two token cells (10 KAS each). It stays with the token’s cells. At graduation the curve cell’s KAS and one token cell’s 10 KAS go into the pool; when Kasseal’s graduation service graduates the token it keeps the other 10 KAS, which pays for setting up the pool’s liquidity.
Developer buyOnly if you set one (at most 5% of the supply): curve cost, the 1% curve fee, its network fee and the refundable deposit of your new token UTXO.
TotalThe sum.

Your wallet also needs a little more than the total available before the first signature (a 5 KAS preparation output is created and comes back to you in the second transaction). If it is short, the app says by how much.
