This will basically allow setting up with nothing more than a main device + backup device + potentially seed phase

and merely depositing ADX to the platform

Basically the idea is as follows:
We create a SC that we deploy via a relayer addr and give that pre-computed SC address to the user (sc address being the hash of the code + tx nonce)

once user deposits more than a min amount of adx for that, we depoy the SC (the relayer deploys the SC)

this SC is also deployed in a way that it gives ability to N addresses to control it, those being the addresses corresponding to the user's PKs (e.g. PC pk, mobile pk, backup seed derived pk)
