USDEV stands for US Dollar Equivalent Value
UP tokens on each blockchain can be assigned a US dollar equivalent value (USDEV) based on the redeem value of UP on that blockchain. USDEV is calculated by multiplying the redeem value of UP on that blockchain in base tokens by the USD market price of that base token on Binance exchange.
For example:
Let us assume BNB is currently worth $500 USD on the open market.
If 1 UPbnb can be redeemed for 10 BNB, then the redeem USDEV for each UPbnb is $5000 (10*500)
To calculate a market USDEV:
If 1 UPbnb can be sold for 11 BNB on the open market, then the market USDEV for each UPbnb is $5500 (11*500)
