The reversibility of NFT transactions is not guaranteed. Once a transaction is executed on a blockchain, it is added to the immutable ledger and cannot be altered. This means that if an NFT is accidentally sent to the wrong person or an unauthorized transaction takes place, it cannot be reversed.
However, some blockchain networks may offer certain features or protocols that can help prevent unauthorized transactions such as multi-signature wallets where two or more parties need to approve a transaction before it is executed. Additionally, some marketplaces or platforms may have their own dispute resolution processes in place but these may vary depending on the platform.
Therefore, it is important for buyers and sellers to carefully review transaction details before finalizing the transaction to minimize the risk of errors or unauthorized transactions.
