Transfers take a few minutes to process, with fees ranging from a few dollars to dozens—this is a longstanding issue with traditional blockchain transfers. There is a project called Plasma, specifically designed to provide a solution for stablecoin payments, claiming to achieve zero fees and one-second confirmation times. It sounds promising, but the key question is: how does it achieve this?

The core logic is actually quite simple: the system covers the transaction fees, so users incur no costs. As long as your wallet contains stablecoins like USDT, you don't need to buy any additional tokens; just transfer or pay directly. Major wallets already support this scheme—just install the wallet and you can use it without any learning curve.

So what is XPL for? It’s not used for payments; it’s more like a "maintenance fund + governance tool" for the network. Holding XPL allows network overseers to earn rewards, developers need to use XPL to pay small fees to deploy applications, and token holders can participate in voting to decide network rules—essentially community governance.

There are also some highlights in practical application. In Latin America and Southeast Asia, it’s used for cross-border remittances, because the advantage of zero fees and instant transfers is especially significant—these regions are very sensitive to remittance costs. Additionally, the team has launched prepaid cards, enabling stablecoins to be directly used for shopping and dining in supermarkets and restaurants, with up to 4% cashback on transactions, expanding the use cases for digital assets.

Privacy considerations are also addressed. During transfers, amounts and information can be hidden, and when proof of funds is needed, users can selectively disclose some data. It supports fast Bitcoin transfers, catering to different user needs. From a product design perspective, this scheme is quite interesting—it not only solves speed and cost issues but also attempts to integrate into everyday life scenarios.
