On September 12th, NEAR Protocol launched a complete "Chain Abstraction" tech stack, aiming to fundamentally solve the current user experience challenges across multiple chains.

Specifically, this solution includes three main components:

**First, Universal Account System**—users can pay Gas fees with any token, and the system will automatically handle cross-chain exchanges. In other words, you can use your Bitcoin, Ethereum, or other tokens directly to pay for fees, without needing to convert to ETH or other chain-specific tokens just for Gas.

**Second, Intent Relay Network**—this is quite interesting. Users don't need to perform step-by-step operations; they just tell the system their intent, such as "I want to buy the cheapest ETH with USDT," and the backend will automatically search for the optimal execution path. Simply put, it turns complex cross-chain operations into a one-sentence task.

**Third, Cross-Chain State Synchronization Layer**—ensures your identity and assets remain consistent across all chains. This way, there's no need to worry about data confusion caused by multi-chain operations.

Projects that have integrated this solution are seeing good data. dYdX, Aurora, and other projects report a 40% increase in user retention. This number is quite impressive.

NEAR co-founder Illia Polosukhin said something very interesting: the goal is to make users "completely unaware of the existence of blockchain," just like using the internet without needing to understand TCP/IP. It sounds like they are trying to make blockchain technology as transparent as infrastructure.
