Add Arweave support for NFT Metadata

[mb-swirlds]

Problem

Can we get Arweave stored metadata files indexed and displaying properly on HashScan.

Right now metadata stored in areweave will not show.

Example:
https://hashscan.io/mainnet/token/0.0.1518294/2?p=1&p1=1&k1=1672434637.410991003

Metadata URL: https://arweave.net/accqwldSOZL84IGcrnPTIt6FgNQTOlsSyEXS4-u8kk4

See UI:

Solution

Can we index or retrieve arweave urls and display accordingly?

Alternatives

There really is only one possible option to accept arweave as a storage solution for Token Metadata.

I see in the metadata that the ar:// URI scheme is used to locate the image.

I am wondering why such URI scheme is not used to locate the metadata JSON file as well (i.e. the decoded metadata field of the token would be ar://accqwldSOZL84IGcrnPTIt6FgNQTOlsSyEXS4). This would greatly help determine for sure this is stored on Arweave. Explorer might otherwise query the Arweave server with a hash which is not an Arweave hash.

IPFS and Arweave URIs
OpenSea supports the storage of NFT metadata in decentralized file networks, so that they can’t be modified by a central party.

If you use IPFS to host your metadata, your URL should be in the format ipfs://. For example, ipfs://QmTy8w65yBXgyfG2ZBg5TrfB2hPjrDQH3RCQFJGkARStJb. If you plan to store on IPFS, we recommend Pinata for easily storing data. Here's a tutorial by Chainlink for getting started: https://blog.chain.link/build-deploy-and-sell-your-own-dynamic-nft/.

Arweave's equivalent is ar://. For example, ar://jK9sR4OrYvODj7PD3czIAyNJalub0-vdV_JAg1NqQ-o.
