The compiler on chain has compiled the compiler itself(a massive project) and the ethegent evm(an even more massive project). Can I promise it is bullet proof. Nope. It is 100% alpha…but it mostly work and works from some massive motoko projects.
Well…let’s put it this way. I thought I was finished in late June and then the motoko team mentioned something about ‘byte parity’ and here we are on August 31st. 
…yes…the plan is to integrate into AstroFlora with ICRC-118/120 support so that you have on-chain compiled, verified wasms ready to deploy and manage…interest pending(interest means financial support). See: https://forum.dfinity.org/t/icrc-105-and-its-seven-cousins/42596. Will probably start off with ICRC-137 governance and them move to whatever makes sense: https://forum.dfinity.org/t/anti-dao-pre-dao-daoless-icrc-137-veto-based-governance/58696
There are a ton of docs at https://moxzi.ai/docs/ and the canister is live at xcn6l-iqaaa-aaaai-raq6q-cai. The cli will take care of most things for you so you don’t have to mess with it directly.
