sUSD-Margined contracts are linear futures quoted and settled in sUSD. One of the key benefits of sUSD settlement is that you can easily calculate your returns. This makes sUSD-Margined contracts more intuitive.
For example, when you make 500 sUSD in profit, you can easily estimate that the profit is worth approximately $500 - since the value of 1 sUSD is pegged closely to 1 USD. Additionally, a universal settlement currency, such as sUSD, provides more flexibility. You can use the same settlement currency across various futures contracts
