6) How does it work in the backend?
While purchasing the debt mirror token is done on layer one Ethereum through a Uniswap V3 pool, the pool containing the assets that replicate the debt pool exists on Polygon.
Users do not have to interact with Polygon at all.
6） 它在后端是如何工作的？
虽然通过Uniswap V3池在第一层以太坊上购买债务镜像令牌，但包含复制债务池的资产的池存在于多边形上。
用户根本不必与多边形交互。
