When you finish a Core Candy Machine mint on Solana, the Candy Machine account (and its Candy Guard, if any) can keep holding rent SOL even after the drop is done. These accounts can be safely closed/withdrawn and the rent claimed back to you. Minted NFTs stay on-chain.
Scan Candy Machines you own as authority, select them, and withdraw to reclaim rent. A 10% platform fee is taken from reclaimed rent. This action is irreversible.
