Что такое Freezing Metadata
OpenSea является крупнейшим и самым известным маркетплейсом в сфере NFT. Одна из причин популярности OpenSea среди создателей NFT — возможность создавать NFT бесплатно и избегать лишних затрат. Оплата комиссии происходит только тогда, когда NFT покупают.
Но есть нюанс: даже после покупки токена, его данные хранятся на серверах маркетплейса. И владельцы OpenSea могут в одностороннем порядке менять данные токена.
При желании можно обезопасить метаданные своего NFT, использовав функцию Freeze metadata.
Зачем нужна функция Freeze metadata
С помощью функции Freeze metadata NFT можно сохранить в децентрализованном файловом хранилище IPFS. Это означает, что ваш токен всегда будет надежно храниться, а файл токена никто не сможет изменить. Даже если сайт OpenSea перестанет работать, информация об NFT не пропадет.
После того как вы «заморозите» файл NFT и его метаданные, в нём нельзя будет отредактировать такую информацию:
• имя файла;
• формат файла;
• описание токена;
• свойства, уровни и характеристики.
Как сохранить метаданные NFT
1. На странице созданного вами NFT нажмите кнопку Edit в правом верхнем углу. Кнопка будет работать, только если токен ещё ни разу не был куплен.
2. Пролистайте вниз до раздела Freeze metadata, включите переключатель и нажмите кнопку Freeze.
3. Далее вы будете проинформированы о том, что после «заморозки» метаданные нельзя будет отредактировать или удалить. Поставьте галочку и нажмите кнопку Confirm.
4. Откроется окно криптокошелька с транзакцией, подтвердите её. Для NFT на блокчейне Polygon это действие будет бесплатным. Если же NFT создан на блокчейне Ethereum, то за транзакцию потребуется заплатить около 100 долларов комиссии сети.
Как проверить, были ли метаданные успешно «заморожены»
Проверить «заморозку» данных вы можете на странице вашего NFT.
Прежде всего, у вас исчезнет кнопка Edit в правом верхнем углу. Также в разделе Details, справа от надписи Metadata будет написано Frozen. Это означает, что файл NFT и его метаданные были успешно сохранены в децентрализованном файловом хранилище.

Should you freeze metadata in Opensea?
NFTs are the hot new thing going around in the cryptocurrency world and are a great investment opportunity if you know what you’re doing.
However, they’re still new on the global stage, and people don’t know as much about them compared to just cryptocurrencies. In this article, we’re answering one of the most asked questions: should you freeze metadata in Opensea? And should you do it for your NFT listings?
Freezing NFT metadata
Freezing your metadata permanently locks and stores said data on decentralised file storage, allowing your data to be accessible to other clients to see and use. Essentially, this stores your item forever, and it can’t go lost or missing.
Freezing metadata locks the following information about the file.
- Item name
- File type (JPG, PNG, GIF, SVG, MP4, WEBM, MP3, WAV, OGG, GLB, GLTF)
- Description
- Properties, levels, and stats
In short, everything will be frozen except any added unlockable content, which can only be unlocked or revealed by the file’s owner.
Should you freeze NFT metadata?
Freezing your NFT data depends on what you’re looking to do with your file. If you’d rather keep your file open to changes such as name, description, format and so on, it’s best not to freeze it just yet.
However, if you’d instead lock everything in place so that the file information can’t be changed no matter whether it stays under your ownership, you can freeze the NFT metadata.

What does it mean to freeze NFT Metadata?
NFT metadata is what defines the properties of a piece. They include the name, image and video associated with it, description, properties, and stats.
During the minting of NFTs, the metadata and other associated files are saved on the Interplanetary File System (IPFS).
IPFS is a distributed system for storing and accessing files, websites, applications, and data.
With IPFS, we have a secure, transparent, and decentralized way to host the metadata of digital assets.
Once the metadata is hosted on the IPFS, you have the option of keeping it frozen or unfrozen.
Freezing the NFT data means locking it up permanently on the IPFS. The properties of the NFT will be permanently locked and stored on the file storage system and cannot be edited or removed.

What are the advantages of freezing my NFT metadata?
Freezing your metadata ensures that your metadata is permanently locked and stored on a decentralized file storage system making your data accessible to your buyers to view and make informed decisions.
It shields you from the risk of ever losing your metadata or it being edited by a foreign body.
Are there disadvantages of Freezing my NFT metadata?
I wouldn’t call them disadvantages per se but I think there are times or occasions when it’s best to leave your metadata unfrozen depending on the NFTs use case.
For instance, if an NFT is serving as a functional game piece, the metadata should be left unfrozen to showcase the dynamic abilities and statistics of the NFT.
So while playing the game, you can unlock new properties to the NFT metadata as you make progress.
This is a way to incentivize buyers to play more and create a new and unique NFT character.
Doesn’t that sound intriguing?
The baseline is that you have to consider the use case of your NFT to decide if the metadata should be frozen or not.

Click on “edit my item”. Search for the “freeze metadata” section and click on the toggle to enable the feature.
click on “Freeze” once the toggle is one.
You’ll get a prompt to confirm that all your information is correct and how it should be because once frozen, there’s no going back.
Once confirmed, you accept and click on “Submit transaction”.
You sign into your wallet and confirm the gas fee to complete the process.
With this done, your metadata is frozen.
