Developer Platform
Aura
During early November, Aura went into its private beta phase, introducing a decentralized network that redefines data access, availability, and scalability for developers across Solana and the SVM. The private beta was offered to a select cohort of developers. Offering them the latest Digital Asset Standard (DAS) API methods and decentralized indexing support for read requests. Initial performance metrics show low-latency responses, and Metaplex will continue to open up access to the network throughout December.
The next major Aura milestones are a public gateway to access the network and the introduction of Aura’s staking and rewards architecture.
Aura also launched on Eclipse, with high initial demand driving over 1.5M requests through the network within the first week. Backpack was the first application to start using Aura, enabling users to view assets supported by Aura in their wallets, while developers on Eclipse gained access to indexing for Core assets, Token Metadata, fungible tokens, Bubblegum (cNFTs), SPL Tokens (including T22), and inscriptions.
Developers can request access to Aura’s beta here.
Core
Core surpassed 1 million total mints in November, with another monthly all-time high of 354k Core assets minted during the month.
A new guide was released to help developers build mint pages with Core Candy Machine, covering how to fetch mint data, validate eligibility with Candy Guards, and implement scalable setups for efficient minting.
Additionally, Core and the full Metaplex suite, are now live on Eclipse mainnet, offering developers the best tools for asset creation on the new chain.
Notable use cases this month included Honeyland, which used Core to optimize breeding and egg creation costs for players, and CandyBlinks, which utilized Core to power its digital asset launchpad and marketplace, allowing for free-mint mechanics for its Candy Mob Business collection.
Token Metadata Optimization & Immutability
After deploying the resize optimization on mainnet in October, which minimizes the program’s onchain footprint, Metaplex announced the next steps for Token Metadata: transitioning to immutability. The program's upgrade authority has been handed off to a multisig of three independent security firms who will conduct final audits over the next six months. No further upgrades will be made to the program beyond addressing security-related bugs, ensuring the program is ready to become Solana's first immutable digital asset standard.
There are a total ~24.2M eligible Token Metadata NFTs with Token Metadata accounts that are still eligible to be resized (as of November 30th). 0.0023 excess SOL can be claimed per Master Edition and 0.0019 excess SOL can be claimed per Edition.
The resize optimization, which frees ~15GB of unused buffer space, continues to enable eligible NFT holders to directly optimize the Token Metadata accounts associated with their NFTs and obtain the excess SOL freed up by the optimization. NFT holders have until April 2025 to execute the resize before the Token Metadata accounts are optimized automatically. Holders can do so directly through the free, no code UI provided by Metaplex (resize.metaplex.com)

Eclipse
November marked the public launch of the Eclipse mainnet, and Metaplex fully deployed its protocol suite, including Token Metadata, Core, and Bubblegum, to enable digital asset creation at scale on the new network. This follows an earlier deployment to Eclipse’s devnet and shows Metaplex's commitment to supporting innovation across Solana and the broader SVM.
To support developers building on Eclipse, Metaplex has detailed guides and documentation specific to the Eclipse network. Additionally, the Core explorer UI now includes options for both Eclipse mainnet and devnet, simplifying asset management and exploration for developers and users.
Documentation & Developer Guides
In November, Metaplex introduced several new guides to support developers building with Metaplex:
Metaplex under the hood: Core. A deep dive article that explores how Core keeps digital assets lightweight yet highly customizable. By using “state blobs” and plugin metadata, Core offers unmatched flexibility and efficiency for managing digital assets.
Next.js template for frontend development. A new Next.js template was launched to make UI development for Solana applications faster and easier. Preloaded with tools like Metaplex Umi, WalletAdapter, Tailwind, and Zustand, it provides a great starting point for developers to create customized, functional interfaces without the need for extensive configuration.
MPL-404 documentation revamp. The MPL-404 section of the Developer Hub underwent a comprehensive rewrite. This update offers clear, detailed guidance on swapping fungibles and non-fungibles, creating hybrid assets, and exploring innovative use cases in gaming, memes, and beyond.
