i don't think any real dude having enough money would keep it in a local currency when he can just buy euro bonds or foreign currency $ or Euro etc ... it i guess only had effected small fishes to some extent, but at the end of the day, the question remain did it help at all curb corruption. Corruption like water will pave its way in terms of monetarily. they will find a way out ... it's not big deal ... such efforts despite looking promising, will be futile.

So my conclusion 'corruption' is not a monetary issue, it's a system issue, fix the system.... and in order to have a 'healthy' system just like we see in the 1st World, everyone makes at least what they deserve or can live good enough ... if not luxurious.

after you give them reasonable good salary keep a check, and hire 'educated' people.

This worked here in Pakistan, our traffic police 'was' most corrupt, Govt raised their salaries 3x .... no more bribe ... they inducted Graduate Students and trained!!! at least our Traffic police dudes are now at Lahore City of Pakistan ... corruption free!!
