The era of chain abstraction is about to begin, and Particle has opened up Universal SDKs for free. In the first phase, @ParticleNtwrk formed the Chain Abstraction Alliance with Solana chain + EVM chain (including the BTC ecosystem). In the second phase, Particle developed the Universal Account, which is the core infrastructure of chain abstraction. Users have a universal account where balances and gas fees are shared. Users are completely unaware of the different blockchains. In the third phase, Particle launched the DEX product based on the universal account—UniversalX, where users can trade just like in a CEX. In the fourth phase, Particle gradually opened up the Universal SDKs. The universal account development toolkit allows developers to easily create DAPPs based on universal accounts without needing to learn and understand the underlying technology of universal accounts. In fact, before the official opening of the Universal SDKs, the derivative DEX product—MYX has already integrated with Particle's universal account. Users can trade perpetual futures in MYX using funds from their universal accounts. More DAPPs and more types of DAPPs will gradually land in the Particle ecosystem, not limited to DEX products. There may also be other types of DeFi, such as integrating with Uniswap to add LP using the universal account. There may also be AI applications, utilizing AI models or integrating financial AI Agent products to perform intelligent financial management across multi-chain ecosystems using the universal account. This could also include games, social applications... In short, the free opening of Universal SDKs marks the imminent start of the chain abstraction era.
