In simple terms, the core idea of Plasma XPL is to create a dedicated fast lane for on-chain stablecoins like USDT. There are two main advantages to operating on this lane: first, transactions basically do not incur Gas fees—just like passing through a toll booth without paying; second, transaction confirmation speed is significantly improved, with efficiency far surpassing the main chain. As a result, users can transfer and pay quickly and cost-effectively, greatly enhancing the on-chain stablecoin user experience. For users who frequently trade, this solution has considerable practical significance.
