Payrolling POS with payment streams similar to

Hi POA team,
Have been following xDAI for some time and somehow missed this STAKE token but happy to rediscover it. I wonder how active xDAI will be maintained and when it is production ready for bigger applications to build ontop of?

My idea is to build a patrolling solution where I will use something like where people can get paid in an easy way and pay a small fee to get paid out. Issue I see now I do also want to let them lock some DAI for interest but then they need to bridge out and lock …

Is there a way I can directly use xDAI in DeFi?
Thank you.
