NFTs are different from the common ERC721 format NFTs. NFTs differ from the standard ERC721 tokens in that some projects deploy dynamic NFTs rather than static assets. Replicant NFTs are described as evolving when the associated ERC404 token changes, altering their metadata and presentation. This distinction highlights the growing variety of NFT designs beyond traditional collectibles.
In practice, the ERC404 signal acts as a trigger that updates the Replicant NFT’s attributes, visuals, or linked data whenever the base token experiences a change. Such dynamics underscore how NFT metadata can respond to on-chain state shifts, creating responsive digital assets. For collectors and developers, this dynamic behavior introduces new considerations for value, rarity, and provenance as NFTs react to token state changes. As standards evolve, more projects may adopt ERC404-driven Replicant NFTs to create interactive and evolving digital assets.
