Recently, I've been looking into the staking mechanics of TRX on JustLend DAO and found that most people don't really understand the calculation logic behind the APY. The sTRX asset is quite unique, as its yield growth follows its own rules. If you don't know how to track it, it's easy to lose track of your actual earnings. The key is to understand the exchange rate mechanism of sTRX, which fluctuates daily and directly impacts your real yield. Only by figuring this out can you accurately assess your portfolio's performance; otherwise, just looking at the APY number doesn't mean much.
