TreasuryCap controls Sui minting
A Sui Coin uses an owned TreasuryCap object rather than an EVM-style contract owner variable. The connected address must currently own that object; merely holding coin objects does not authorize new supply.

Talk to the teamSui gates coin permissions behind an owned TreasuryCap object rather than a contract owner variable. The connected wallet must currently hold that exact object before Slingzero will build a mint transaction.
Yes. Enter any valid Sui address in the recipient field; the newly minted coin object is transferred there directly instead of staying with the signing wallet.
Slingzero does not add an artificial cap. The practical limit is the u64 balance range Sui coins use internally, so double-check very large amounts before approving.
No. Minting only calls the coin module's mint function to increase circulating supply; the name, symbol, and decimals set at creation stay exactly as they are.
