Considerations for NFT developers


An NFT or non-fungible token is a record on a blockchain that is associated with a particular digital or physical asset. The unique digital representation on a blockchain allows the proving of ownership as well as their trading.

NFTs on the Internet Computer

The Internet Computer Protocol brings a lot of potential for NFTs.

NFT asset storage for cross-chain NFTs

NFT assets, including images, sound clips, or videos, can be securely stored on-chain entirely on ICP, even while the NFT itself is minted on various chains, such as on any EVM chain.

Refer to this example on how to host metadata on the ICP of an ERC-721 NFT minted on an EVM chain.

Generative NFTs

Dynamic NFTs can be curated to evolve based on both data stored on ICP or external APIs. NFT assets can be modified in real-time by calling API requests on-chain using HTTPS outcalls.

Minting NFTs on ICP

For developers seeking to store assets and mint NFTs directly on the Internet Computer Protocol (ICP), an NFT implementation typically encompasses three core functionalities:

  • A registry to monitor ownership and facilitate transfers.
  • A ledger or transaction history.
  • The actual asset itself (in the case of digital assets).

NFT interface specifications and implementations

  • DIP-721 is an ERC-721 style non-fungible token standard built mirroring its Ethereum counterpart and adapting it to the Internet Computer, maintaining the same interface.

Refer to the creating NFTs on ICP tutorial for more information.

  • ICRC-7 is a standard for the base implementation of non-fungible tokens (NFTs) on the Internet Computer.

The ICRC-7 standard is still currently in the drafting stages and is not yet live in production.

NFT marketplaces and launchpads

Additionally, you have the option to utilize various platforms for minting your NFTs, such as:
