Plasma is a recently popular new public chain that has a close relationship with Tether. I listened to an interview with its CEO Paul Faecks by Liu Feng, and there was a great question: As a payment chain, what are the three most important dApps for Plasma? The CEO's answer is — ◦ Deposit and withdrawal channels Users need a simple way to enter and exit the ecosystem. I understand this to mean there should be compliant channels that allow for the free exchange of fiat currency and USDT. The Bridge, which was acquired by Stripe, mainly does this. ◦ Lending protocols This is mainly in cooperation with AAVE, and there will be some customized features. The CEO specifically mentioned BTC; Plasma supports native wrapped Bitcoin, allowing for cross-chain transfers in and out of BTC. Additionally, users can use Bitcoin as collateral to borrow USDT for consumption or investment. He mentioned that users see stablecoins primarily having three major uses: savings, consumption, and global transfers, with significant differences among the three scenarios. As a savings asset, users naturally hope to earn some returns, and holding USDT does provide returns. ◦ Cooperation with payment companies Building a connection layer between Web2 and Web3, although end users may not necessarily see it. Plasma will collaborate with Yellow Card in Africa and more institutional partners. The main focus is on having a solid user base in Web2 while also being willing to embrace Web3 payment products. #Plasma's mainnet will go live before the end of this summer.
