WHY IT NEEDS A POLICY

Why mintNFT needs a policy

Minting an NFT is a financial/irreversible blockchain operation: it creates an on-chain asset (ARC-3/ARC-69 standard), commits ALGO fees, and results in a permanent ledger entry. While not directly moving currency, it constitutes a financial commitment (fees, asset creation with market value) and cannot be undone on the blockchain.
