如何确保只有NFT所有者才能在合约中进行转让？

Question

嘿大家！我正在努力实施NFT合同，并希望确保只有NFT的合法所有者才能进行转让. 我有这个传送功能：

public fun transfer(
    nft: DevNetNFT, recipient: address, _: &mut TxContext
) {
    transfer::public_transfer(nft, recipient)
}

这个检查是在public_transfer方法中完成的，还是我需要添加额外的逻辑？

To clarify further, its not specifically the public_transfer that is checking ownership, but rather the Sui transaction semantics. For a transaction to accept an object as input, you must have ownership, meaning the senders address must match the owner address on the object. Shared objects, however, treat everyone as an owner for the purpose of transactions.

CHECKWITHEGORBefore the transfer of an NFT, the public_transfer function checks whether the sender holds the NFT. Thus, the logic is indeed built into the public_transfer method.

You actually dont need this function as you can directly call tx.transferObjects within a PTB.
