Token Metadata Optimization
Metaplex notified developers and announced an important update impacting Metaplex’s Token Metadata (TM) program that will take place in September. This update will reduce the size of metadata accounts by over 35%, significantly decreasing the resource requirements on the network and lowering minting costs for users by reducing data storage costs. Master Edition and Edition accounts will both see reductions of more than 17%, making it far more efficient for storing and managing metadata, as well as cheaper for users. Starting on September 9th, the update will be released on devnet, with a planned mainnet deployment scheduled for September 30th.
Core
The Core standard continued to gain traction, with over 230,000 Core digital assets now minted. In addition to adoption, the Core standard received significant upgrades including a successful audit, two new plugin launches, and the release of a new developer guide.
The AppData External Plugin went live on mainnet, fully integrated with DAS support. This plugin allows developers to attach and manage custom data directly within digital assets, simplifying tasks like tracking game stats, loyalty rewards, or event ticket statuses (onchain ticketing with AppData example). Third parties, such as marketplaces or event organizers, can update data on assets without needing additional programs. To learn more, devs can watch the explainer video, read the AppData article, or review the developer documentation.
The Edition Plugin for Core became easier than ever to use. With the latest update to the Core UI, creators and developers can create Editions and Prints of their digital assets with no code. Thanks to feedback from the community, Metaplex introduced a unified framework for Editions, making digital asset management simpler and more intuitive.
For those looking to integrate Core into their smart contracts, the new Core Anchor Guide is essential. This guide makes it easier than ever to use Core's single account model in Anchor projects, providing step-by-step instructions and detailed examples on deserialization and cross-program invocations (CPI). It’s designed to streamline the development process and help devs get the most out of Core.
In addition, Madshield completed a Core security audit, which included the latest plugins and updates to the standard. All identified vulnerabilities were addressed, ensuring that Core remains a secure foundation for digital asset creation.
Finally, the recent update on mainnet allows devs to add or remove digital assets within Core collections, offering greater flexibility in managing collections.
EclipseSVM
Metaplex expanded to Eclipse, bringing the power of Solana digital assets to Ethereum’s first SVM Layer 2. With Core, Token Metadata, MPL-404, Candy Machine, and Token Auth Rules deployed, developers can now leverage the same standards and programs that have powered digital assets on Solana mainnet on the Eclipse L2. This move expanded Metaplex’s position as the leading digital asset protocol within the growing SVM landscape.
SonicSVM
Metaplex deployed its product suite to the Sonic SVM, the first gaming focused Solana L2. The deployment included Core, Token Metadata, Candy Machine, and Auth Rules, which are now live on Sonic’s devnet and testnet. Game developers can now use these tools to create new gaming experiences on the Sonic SVM.
Hydra UI Fork
The Hydra UI fork was introduced, making the process of creating and managing Hydra Fanout Wallets easier. This update, a fork of the original Cardinal UI, modernizes dependencies and incorporates automatic priority fees, allowing users to manage their wallets without needing to write any code. Developers benefit from additional ease of use, as existing scripts require no updates to accommodate the new features. This tool is designed to simplify workflows and improve efficiency for those managing multiple wallets.
Compressed NFT Library Upgrade
Metaplex released an update to the Bubblegum JS SDK that makes working with cNFTs simpler. The update automatically trims unused proof data, reducing the size of transactions and making transfers, updates, and burns faster and more efficient. This improvement eliminates the need for additional client-side calculations, simplifying the development process. The upgrade is particularly useful for developers focused on optimizing their applications for speed and efficiency.
