I do not know it his would be possible in Ark but in NEM this is possible and this technology already exits since 2015 in NEM.
It all seems useless if not used correctly.

Look here what happened:
https://cointelegraph.com/news/coincheck-stolen-534-mln-nem-were-stored-on-low-security-hot-wallet

because some illiterate moron at the exchange was using a simple wallet account instead using a multisig account.
Events like this are really damaging not only for NEM but for the whole crypto sphere.

I hope Ark implemented similar technology as well.

Do the Ark Blockchain have any Grant for project or dApp develop on Ark network?

I guess you are talking about the voter rewards?
The delegates are using scripts. These are not multi payments, but multi transactions.

With multipayments you can send multiple payments in only 1 transaction. Which saves a lot on transaction fees.
Also, this is more available to the end user, without using any scripts.

It also makes life easier for those that share out dividends to specific addresses. I'm really happy about this update.

can you feel it? ark is about to pump hard!
oh man, the ark roadmap is so good!

That's correct.

ark might not be the first blockchain, or the first anon coin but here are some of the terms or techs ark is invented for the blockchain;

interperability,
plug and play blockchain,
all-in-one blockchain,
modular blockchain,
plugin blockchain,
1st 1 vote = 1 count dpos,
1st dynamic fees dpos
i don't see anyone is using the term ecosystem blockchain before ark, so. let us know more if you think the ark team and people invented it.
the scammers and copycats going to take these terms and techs all the way to their bank.
i can say ark team and community are the OG in this blockchain and they know what's going on. ark is the shzit yo!
you guys are amazing, the ark team and community!
will see how this go.

oh, ark team and community code their own blockchain, so;

beware of those too good to be true blockchains, or high pump and high volumes blockchains out of rat hole, chance your money will be gone soon.
beware of those ico, ieo, ioo, ifo, ifcku-o... fake volumes and fake pump, things like that.
this is not an investing, investment, or advisor post do you own dd
