This guide walks through several ways to securely create and manage NFTs that change over time, also known as mutable NFTs.

Why is this a thing? Aren't all NFTs immutable and uneditable? ... Simply put: mutable NFTs can be modified by their creator at any time.

December 20, 2021 - I think I have decent understanding of NFTs after reading https://eips.ethereum.org/EIPS/eip-721 but I have the following questions that doesn't seem to have been answered adequately anywhere. Issues with mutability of URI in the metadata While there are use-cases where it is helpful to have it mutable...

P.S.: If you're interested in a more in-depth explanation, here's why your NFT might not be on the blockchain. ... Simply put: mutable NFTs can be modified by their creator at any time.

August 1, 2022 - This guide walks through several ways to securely create and manage NFTs that change over time, also known as mutable NFTs.

February 12, 2022 - The problem of immutability is: the majority of all NFTs store their data in centralized servers. NFTs are portrayed as being fully on-chain, as something immutable that allows holders to fully own digital pieces of art forever. That’s just not the case. Well over half of all NFTs are mutable.

September 18, 2021 - Authorized_editor: the name of the account which must be authorized to access the collection the NFT belongs to. Asset_owner: the name of the account belonging to the current owner of the asset -it is not necessary to be the owner of the asset in order to modify its mutable data; you just need to be authorized to do so, or be its creator.

March 22, 2022 - e.g. a weapon NFT whose level can be upgraded. Reflecting this kind of change in level would require the metadata to be mutable, thus required self-hosting metadata.

These NFTs with mutable metadata are known as Dynamic NFTs because the information can be changed later by following certain rules that allow them to be more versatile.

August 10, 2021 - In other words, mutable means that the jpg or gif of the NFTs could be changed anytime.

March 17, 2025 - Dynamic NFTs are a groundbreaking evolution of traditional NFTs (Non-Fungible Tokens) that have the ability to change or transform based on certain pre-set conditions, user interactions, or other external factors.

Using Irys’s mutability features, you create a single, static URL that is linked to a series of transactions. Then, you can add a new transaction to the series at any time, and the URL will always resolve to the most recent transaction. You’ll mint your NFT using a mutable-style URL, and then push updates to that URL.

October 21, 2025 - Dynamic NFTs can store or reference up-to-date information about properties or other real-world assets, improving transparency for buyers, sellers, and service providers. Artists can design pieces that evolve with time, audience interaction, or external signals such as weather or market data. These works emphasize change and participation, allowing collectors to own art that is alive and responsive instead of frozen at a single moment. Mutable tokens introduce new trade-offs.

November 8, 2023 - The base NFT smart contract implements the ERC-721 standard while also encoding the mutable rules and logic required for dynamic functionality. This includes tracking state changes in variables, structs, and mappings as well as exposing methods to change state.

August 3, 2022 - What cannot be changed about immutable NFTs is their underlying data. That’s because they possess permanently unchangeable traits that are recorded on the blockchain and can never be altered. The new breed of mutable NFTs on the other hand comes with data and traits that can change over time via outside interference.

August 22, 2023 - After years of research and development work, AllianceBlock proudly unveils the Nexera Protocol — ushering in the next era for the next generation of NFTs. Built with current NFT standards, the Nexera Protocol enables the creation of mutable and composable NFTs, called MetaNFTs.

July 2, 2022 - You have no control over the metadata of your NFTs.

June 7, 2021 - So we are introducing the concept of a mutable NFT which would be based on the allocation ID on our platform.

It includes 40 NFTs (Geneses) that are on-chain mutable and revenue-generating.

Mint the NFT with the Metaplex standard, which allows for metadata storage. Store metadata off-chain on services like IPFS or Arweave. Set the metadata as mutable by creating a metadata account with a reference to the off-chain URI.
