iUSDT token is a wrapped token provided through Iskra Bridge so that USDT can also be used on Iskra Mainnet (Klaytn).
If you bridge the Ethereum chain-based USDT which was initially transferred to the Iskra Portal Wallet to Iskra Mainnet (Klaytn), it will be converted to iUSDT tokens.
iUSDT tokens can be exchanged for other assets on Iskra Mainnet (Klaytn) in the near future. (Swap service is slated to be opened for asset exchange later)
