# 4.3 Layer 2 Scalability Strategy and User-Perceived Performance Architecture

TRIPLE PLUS actively adopts a Layer 2 architecture to support a large user base and provide a real-time transaction environment.

* Polygon PoS is adopted as the main execution chain, offering an average transaction fee of less than $0.01 and a transaction speed of 2–3 seconds.
* A bi-directional bridge for asset transfers between the Ethereum mainnet and Polygon is planned to be introduced gradually—not only the official bridge, but also bridges based on LayerZero and Wormhole.
* Smart contract execution is optimized through multi-threaded processing and gas efficiency algorithms, enhancing the perceived speed of transactions for users.

This architecture ensures that users can experience seamless and stable financial transactions—such as bond settlements, liquidity staking, and payments—without delays, especially in real-world economy-based financial use cases.
