The Automatic Adjustment Mechanism of USN Annualized Rate

Basic concept	Basic concept
Average 24-hour USN exchange rate:	Snapshot the USN exchange rate every 5 minutes, and then add and average thesnapshot data for the past 24 hours (The page displays the data in real time)
Judgment time of USN exchange rate:	UTC00:00 Use the average 24-hour USN exchange rate at this time point to determine whetherto adjust the annualized rate on the same day
Implementation time of annualized rate adjustment:	UTC 03:00 When meeting the following conditions, the latest USN annualized rate will beimplemented at this time point on the same day
Vote: The time difference between the judgment time and the implementation time is used for giving the market to react
USN annualized rate rise mechanism
Trigger conditions:	When average 24-hour USN exchange rate <0.98 USDT at UTC 00:00
Annualized rate adjustment range:	+2%
Maximum annualized rate:	30%, that is. when the annualized rate is 30%, the USN annualized rate will not be rose
USN annualized rate reduction mechanism 1
rigger conditions:	When average 24-hour USN exchange rate > 1.02 USDT at UTC 00:00
Annualized rate adjustment range:	-2%
Minimum annualized rate:	1%, that is, when the annualized rate is 1%, the USN annualized rate will not be reduced
USN annualized rate reduction mechanism 2
Trigger conditions:	When average 24-hour USN exchange rate is from 0.98 USDT to 1.02 USDT for 2consecutive days at UTC 00:00 (pegged)
Annualized rate adjustment range:	-1%
Minimum annualized rate:	3%, that is, when the annualized rate is 3%, the USN annualized rate will not be reduced
Note: When the USN exchange rate is continuously pegged, the scale of USN supply can be promoted by reducing USNannualized rate.
