Well, there are some platforms that are compliant with the Sharia with ethics and morality. At least, there is Onegram based in Dubai and another one based in Bahrain (I don't remember its name) and it's surely not the only one, otherwise, it's an interesting niche for any company looking for a cash-cow.
When I searched about it I learned there are cryptocurrencies that they consider Halal, and some others are in a grey area (it means, it depends on how it suits them), while some like Monero are considered 'Haram'.
There are also some DeFi platforms that they don't allow and consider it's 'Haram'. For example, yearn.finance
In fact, this kind of attitude does not occur in the Dubai government in other countries, many may also distinguish between very strict religious laws which are strictly obeyed by the people there so that some programs/coins are not allowed, such as those that lead to gambling, for example.
