Indonesian government does not allow crypto as a legal payment system, but crypto is only permitted as a tradable asset or instrument and must be in the form of crypto utility or crypto backed asset.
It mean IDRC token must be backed by asset and must have a stable price.
You are referring to stablecoin but from the looks of it, looks like they do not want to create another stablecoin but instead a new kind of token. Take a look at their goal mentioned above:
Making Everyone Successful Our ultimate goal is to generate growth for our business, but that also means growth for our developers, for our investors, and for the value of IDRC itself.
That alone denies the fact that they are going to be another stablecoin. The project looks fishy, I do not recommend you to participate in their sale unless they can provide complete and necessary information about their project.
