NFT - Algorand - Token URI: IPFS and max size

When minting NFTs with Algorand, the metadata URL of the NFT must use the IPFS format.

As of the writing of this article, no other formats than IPFS are supported by Algorand.

Furthermore, the token URI max size is 96 bytes. See Algorand documentation.

Additional information is available at Algorand Foundation

The token URI returned SHOULD be an ipfs://... URI so the metadata can’t expire or be changed by a lapse or takeover of a DNS registration. The token URI SHOULD NOT be an http:// URI due to security concerns.
