Developer Platform
Core
June has been a milestone month for Core, surpassing 130,000 digital assets minted and countless new features shipped, including five new plugins, as well as several integrations within the ecosystem.
The AppData and LinkedAppData external plugins were released to devnet, two plugins that are a game-changer for digital assets. Developers and creators can now write custom data directly to assets or entire collections, which opens up use cases not possible before like loyalty programs, on-chain subscriptions, or game points stored directly on assets without the need for complex programs or setups. These plugins simplify development and boost security by enabling dynamic interactions with dApps, games, and marketplaces.
The Verified Creator and Autograph plugins with DAS support were deployed to mainnet, enhancing the on-chain digital asset experience. The Verified Creator Plugin adds trust and authenticity by allowing creators to sign their assets, while the Autograph Plugin enables owners to leave custom messages on their assets.
Additionally, the Update Delegate Plugin is now live on devnet, adding flexibility and simplifying the management of Core assets and collections. By delegating update control to a third party, this plugin is ideal for scenarios such as games needing to level up or change asset attributes stored in the wallets of players.
Core Candy Machine received a major upgrade with five new guards, including but not limited to Asset Payment, Asset Burn, and Asset Mint Limit, to supercharge and secure the minting experience.
Guides on immutability and the Oracle Plugin were released, along with a short video explaining the Oracle Plugin and a UI walkthrough on setting up the plugin.
Backpack and Magic Eden announced full support for Core digital assets, further expanding the Core ecosystem.
MPL-404
In June, the first hybrids using MPL-404 were launched, marking a significant step forward for hybrid DeFi on Solana. MPL-404 reshapes digital assets by integrating fungible and non-fungible assets into a unified framework.
In collaboration with Mutant Labs, pioneers in the hybrid ecosystem, and building upon SPL-404, MPL-hybrid has been added to the Metaplex Program Library and open-sourced.
Powered by the new MPL-hybrid swap program, MPL-404 will support various non-fungible and fungible standards on Solana, allowing easy exchanges between assets and creating new opportunities for liquidity and engagement.
Currently in alpha, MPL-404 supports the exchange of Core digital assets and SPL fungible tokens. Additional standards integrations, developer documentation, and new features are on the horizon.
