Answer: After the USDJ swap, the USDJ token has been removed from the Tron DAO Reserve PSM. This means that the USDJ token is no longer available for purchase through the PSM, and anyone who previously held USDJ tokens must now swap them for USDD tokens. The swap was done in order to improve the liquidity of the USDD token, and to make it easier for users to access and use the token. The swap also allowed for more flexibility in the token’s use, allowing it to be used in more places than before.
