Cross-chain transactions are really a hassle—bridging fees pile up one after another, the operation process is dizzying, and assets are scattered across seven or eight chains, making them hard to find.

But now there's a project called VOOI, which is changing the game with a concept called "chain abstraction." It's been quite a hot topic in the DeFi circle in 2025, with the core idea of hiding the complexity behind the scenes.

What does chain abstraction mean? Simply put, it boils down to two points: you don't need to worry about which chain your assets are on, as the system automatically manages the routing; and you no longer have to repeatedly operate complicated cross-chain bridges.

It sounds like a combination of "multi-chain wallet + automatic routing + one-click aggregation," but the actual experience remains to be seen once you try it yourself.
