What is Cryptocurrency Wallet?

A cryptocurrency wallet is an application that functions as a wallet for your cryptocurrency. It is called a wallet because it is used similarly to a wallet you put cash and cards in. Instead of holding these physical items, it stores the passkeys you use to sign for your cryptocurrency transactions and provides the interface that lets you access your crypto.

Modern cryptocurrency wallets make the blockchain accessible to everyone. When cryptocurrency was first introduced, sending cryptocurrency was a manual task that required entering long keys. Today, the software does most of it for you.

Preparing your digital asset

To enable efficient NFT storage, your files or your digital asset should be stored off-chain. That is mean that you will not store inside the block-chain, but you only store the link to the file. This link should also be link to some kind of decentralized storage. There are several options on storing the file into decentralized storage.

InterPlanetary File System (IPFS)

The InterPlanetary File System (IPFS) is a protocol, hypermedia and file sharing peer-to-peer network for storing and sharing data in a distributed file system. IPFS uses content-addressing to uniquely identify each file in a global namespace connecting IPFS hosts.

To enable access to the file you upload, you will need some kind of gateway between IPFS Universe and HTTP/S Universe. At this momen, service such as pinata.com is offering free service with some limitation. The limitations for free service are

• 100 Maximum pinned file
• 1GB Maximum Storage
• No dedicated gateways
• 10.000 Maximum request

To upload your file, please navigate to Pinata Platform, create your account and upload your file. You will receive one CID (Content Identifier) for each file that you upload. Each of the CID can be constructed into static URL to access the files. Below is the example of how the file will look like after uploading into IPFS.

To retrieve you static URL using share gateway, please click on the filename, the leftmost column, which will redirect you to the static URL. Then you can save the URL and use it on your NFT field.

NFT.Storage

The other way to store you file, is on NFT.Storage. Qouting from NFT.Storage,

NFT.Storage is a long-term storage service designed for off-chain NFT data (like metadata, images, and other assets) for up to 31GiB in size per individual upload.

Data is content addressed using IPFS, meaning the URI pointing to a piece of data (“ipfs://…”) is completely unique to that data (using a content identifier, or CID). IPFS URLs and CIDs can be used in NFTs and metadata to ensure the NFT forever actually refers to the intended data (eliminating things like rug pulls, and making it trustlessly verifiable what content an NFT is associated with).

NFT.Storage stores many copies of uploaded data on the public IPFS network in two primary ways: in dedicated IPFS servers managed by NFT.Storage, and decentralized on Filecoin. Since IPFS is a standard used by many different storage services, it's easy to redundantly store data uploaded to NFT.Storage on any other IPFS-compatible storage solution from pinning services, to your local IPFS node, to other storage networks like Arweave or Storj. And as time goes on, NFT.Storage will increasingly decentralize itself as a public good!

To store your file at NFT.Storage, please navigate to nft.storage and create your account. You can also use [github.com github] account to register. Once registration is finished, you can start uploading your file using Files menu-item on Navigation Bar on the top of the screen.

Click Upload button and follow the on-screen instruction to upload your file. Below are the screen capture of the result after file is uploaded.

NFT Storage Result

Click on Action button, and click View URL to see the static URL result of your file, it will looks something like below link

NFT Storage will use share gateway without any limitation, however, there no guarantee that the gateway will always be available during the request.
