The name, ticker and picture people will see everywhere the coin trades. They are written into the mint and can't be changed later.
Links go into the coin's metadata, so pump.fun, wallets and screeners show them. All three are optional.

Pick a route for the coin's creator fees. It's written into the launch transaction and locked: nobody can change it afterwards, you and Unics included.
An optional first buy goes out right after the launch lands, before anyone else has the address. Leave it at zero to skip.
The estimate assumes nobody buys before you, on pump.fun's starting curve. Up to 20 SOL.
One signature creates the coin and writes its fee split on pump.fun in the same transaction. Either all of it lands or none of it does.
