Developer Platform
Core
May saw significant advancements for Core, the next-generation standard for digital assets on Solana, enhancing the developer experience and expanding the utility of Core digital assets. Marketplaces OKX and Mallow integrated support for Core assets, improving visibility and trading opportunities. Solflare included support for the transfer of Core digital assets. Truffle announced new Core-enabled functions like digital asset gating, SPL token payments, and Core assets airdropping.
Mad Shield's audit for Core was completed and all identified vulnerabilities were addressed promptly. The first Core external plugin, the Oracle plugin, went live on devnet and mainnet. This plugin enables assets to react to real-world data, affecting lifecycle events such as create, transfer, burn, and update. The launch of the Oracle plugin also included broader DAS support for Core plugins on mainnet, enhancing the functionality and flexibility of Core digital assets. Additionally, the Immutability and AddBlocker plugins were introduced, providing more control over asset behavior and security.
The Core Candy Machine Print Editions guide was released, simplifying the process of minting editions. The Metaplex Core JS SDK v1.0 also launched, offering a streamlined development experience with new functionalities like automatically resolving additional accounts for external plugins.
MPL-404
Metaplex introduced MPL-404, the future of hybrid DeFi on Solana in collaboration with Mutant Labs. This on-chain protocol and framework combines the liquidity of fungible tokens with the unique qualities of non-fungible assets. Mutant Labs contributed its SPL-404 standard to the Metaplex Program Library, establishing the foundation for hybrid DeFi innovations. MPL-404 offers a toolkit for dynamic digital experiences, leveraging Solana's low-cost, high-performance design. Through new on-chain hybrid programs that leverage Metaplex NFT standards such as Core and Token Metadata, combined with powerful self-serve developer tools and SDKs, Metaplex will expand distribution and access to the latest hybrid DeFi innovations for all developers, ensuring that Solana remains the premier chain for digital assets and web3 communities.
Anchor
Updates for Solana developers using Anchor include Kinobi 0.18.7-alpha.0, adding support for generating Anchor types for SDKs. Kinobi 0.18.8 supports generating Anchor types for native Solana programs starting with Core, eliminating the need for Rust hacks and improving compatibility, resulting in faster development and easier workflows.
Bubblegum Support for MIP-9
Bubblegum support for MIP-9 was deployed to both devnet and mainnet, with Rust and JS packages published. This update prevents the creation of Merkle trees requiring more than 17 proofs, enhancing composability and preventing spam.
