FAQ

What is a Capsule NFT?

A Capsule NFT is an NFT that follows the ERC-721 standard and is able to store other tokens, which may be redeemed at a later date. Capsule NFTs are created using the Capsule Protocol.

On what blockchains does the Capsule Protocol operate?

Currently, the Capsule Protocol operates exclusively on the Ethereum blockchain.

The Capsule team is exploring opportunities to port to other chains.

What internet browsers does the Capsule Protocol support?

At the current state of beta, the website is being actively maintained on Chrome and Brave browsers - we do not recommend using other browsers as there may be bugs/issues with the frontend.

What kind of tokens can be stored in a Capsule NFT?

Currently, the Capsule Protocol supports the ability for users to store ERC-20 tokens, ERC-721 tokens and ERC-1155 tokens .

The Capsule team is exploring the ability to store additional token standards in the future.

Where can I sell my Capsule NFTs?

While there are many NFT marketplaces that you can sell your Capsule NFTs, we recommend the OpenSea platform, currently the largest NFT marketplace.

What is a Capsule Collection?

A Capsule Collection is an NFT collection generated by the Capsule protocol. An NFT Collection is like a library, housing any amount of NFTs inside similarly to how a library houses books. An example of an NFT Collection can be seen here.

Can a Capsule NFT store another Capsule NFT?

Yes a Capsule NFT can store a Capsule NFT, which can also store another Capsule NFT. Capsule NFTs can store an infinite chain of Capsule NFTs.

How many tokens can a Capsule NFT store?

Capsule NFTs can store a limitless amount of a single token standard. To elaborate further, a Capsule NFT is able to store many different kinds of ERC-20 tokens, ERC-721 tokens, or ERC-1155 in a single Capsule NFT, but not a combination at the same time.

Example of Storing ERC-20, ERC-1155 and ERC-721 Tokens

If you would like to store ERC-20 tokens and ERC-1155 tokens with ERC-721 tokens, a user is able to do so by first creating an ERC-20 Capsule NFT and an ERC-1155 Capsule NFT separately and then adding it to an ERC-721 Capsule NFT along with any other ERC-721s that the user would like to include.

What is collection locking?

Locking a collection sets a limit, determined by the collection owner, to the amount of NFTs that can be minted in a Capsule Collection. Once the limit about has been reached, no one, including the owner, can mint any more NFTs in the collection.

Is it possible to prevent a collection from being locked?

Yes. There are two ways to permanently prevent a collection from being locked:

• Set the lock number to the maximum unit 256 minus one (2^256 - 2)

• Or transfer ownership of the unlocked collection to the 000 address

Can you unlock a collection that has been locked?

No. Once a collection has been locked, it may never be unlocked.

What is the difference between a Collection Owner and a Metamaster?

A Collection Owner is able to lock any Capsule Collections they own. In addition if a Capsule Collection is private, only the Owner is able to mint to that collection.

A Metamaster is the controller of all metadata in the Capsule Collection, meaning they have the ability to reassign tokenURI data.

Can I transfer collection ownership?

Yes. While there is currently no way to perform this function on the front end, a Collection Owner may view their collection on Etherscan and call the transferOwnership method to the desired address (for more details, see section Capsule.sol). We currently recommend only highly technical users to attempt this function.

The CapsuleNFT team is planning to create a more intuitive front end user experience for this function in the future.

Can I transfer Metamaster privileges?

Yes. While there is currently no way to perform this function on the front end, a user with Metamaster privileges to a collection may view the collection on Etherscan and call the transfer updateTokenURIOwner method to the desired address (for more details, see section Capsule.sol). We currently recommend only highly technical users to attempt this function.

The CapsuleNFT team is planning to create a more intuitive front end user experience for this function in the future.

Does the Capsule Protocol have a token?

There is currently no token associated with the Capsule Protocol.
