Assets for on-chain games must be adaptable and evolvable. The token standard of which gaming assets are built on must allow the asset to grow with the player throughout the game. NFTs based of ERC-721 and ERC-1155 suffer from rigid fungibility and the inability for growth.
ERC-3525 by Solv Protocol and ERC-2114 offers NFTs with a modular architecture that meets the complexities of on-chain games. A new dynamic standard of NFTs also allows us to build more fully-featured marketplaces with a user experience tailored towards the needs of gamers.

The new ERC-3525 standard with the triple scalar model <ID, AMOUNT, SLOT> gives rise to many ways to architect the smart contracts through which on-chain games are powered. With the archaic but dependable ERC-721, collectibles in game can only exist with their pre-selected/generated metadata in perpetuity. There can be no growth or modifications done to it.
The same goes for ERC-1155, these assets suffer from rigid fungibility while trying to serve an industry that requires their assets to be highly pliable, adaptable, and evolvable. The token standard which serves the gaming asset must allow the asset to grow with the player, and ERC-721 & ERC-1155 can’t.
