I used @dappOS_com’s xBubble Coding to help my brother build a “Shopee Profit Scanner” website in just 19 minutes.

My brother has been doing Shopee for seven years. His main market is in Southeast Asia, and the combined daily turnover of his 5 stores is about $1,000–$2,000. I hadn’t really calculated the costs in this line of work until last week, when I helped him build a tool to pull the data—after we finished, the two of us just went silent.
His business is being scraped away by four “invisible siphons”:
- Shopee platform commission: 6%–10% (depending on category)
- Cross-border bank wire transfer fees: $25–$40 per transaction + 1.5% FX rate spread
- USD → RMB exchange: another layer of 0.3%–0.5% spread
- Bank deposit processing time: 3–5 business days
Add it all up: of the $1,000 worth of goods, my brother only ends up with about $850—meaning a 15% “invisible cost.” Over a year, the profit it eats up is equivalent to working an extra two months for nothing.
My brother has thought about using USDT for settlement, but he couldn’t even figure out what “RPC nodes” are. The off-the-shelf SaaS tools on the market are all customized for big sellers, and monthly fees start at around $200—so someone like him can’t really use them.
That’s why I helped him set up this “Shopee Profit Scanner” tool on xBubble Coding. Now every day he just opens his browser and can see exactly how much more he can earn from doing USDT than from using the bank.
After it was built, my brother told me something that really moved me: “After doing e-commerce for seven years, this is the first time there’s been a tool made for a seller like me—not for those big bosses in Yiwu who’ve done over a billion a year.” That’s the most interesting part of the OPC era—AI tools let a seller who can’t write code also have their own dedicated business infrastructure.
A lot of friends ask me: In the AI era, what tools can small business owners without a technical background use? Before, I could only recommend Excel templates or Feishu spreadsheets. Now I’ll recommend xBubble Coding—it lets you build tools “specifically for your business,” even if you don’t understand the technology. That’s the real thing that changes the game.
