 Bubblegum V2 is the latest iteration of the Metaplex Protocol program for creating and interacting with compressed NFTs (cNFTs) on Solana. Built for large-scale operations, Bubblegum V2 preserves all the benefits of the original Bubblegum while introducing powerful new features. Compressed NFTs make it possible to scale the creation of NFTs to new orders of magnitude by rethinking the way we store data onchain. {% .lead %}

 The Trifle Program is built upon the Escrow extension of Token Metadata. It uses a Creator Owned Escrow, or COE, using a Trifle PDA as the creator and manager of the COE. Its purpose is to add onchain tracking and composability around NFT ownership. Additionally, the ability to specify rules and effects around token ownership allows for complex ownership models to be implemented by creators.

 **MPL-404** is a new model for digital assets, web3 games, and onchain communities. At the core of the model is a swap program (**mpl-hybrid**) that trades a fixed number of fungible assets for a non-fungible asset and vice versa. The swap is a dual escrow system, ensuring that all available non-fungible assets are backed by escrowed fungibles and vice versa.

 ## Swapping
 
 The ability to freely move between fungible and non-fungible assets in a predictable way allows this new asset class (often called **hybrids**) to take advantage of the best aspects of both asset types. **Non-fungible assets can now benefit from the liquidity, distribution, and DeFi opportunities** associated with fungible assets. Conversely, fungible assets can now benefit from the improved utility, collectability, and identity that come from the non-fungible world.
