Personally, I think that there are still no regulations on the issue of smart contracts. On the one hand, with globalization, the implementation of smart contracts will be possible everywhere. But the synchronization of legislation will be a major obstacle. What if you use a smart contract in several countries.
I think there will be no problem if everyone has to use smart contracts from several countries, because as we have seen also in the use of currencies from several countries by everyone in the world, the only obstacle in this is the application of smart contracts. it is in every country, because obviously it would be against the regulations of each country.
