why there is unknown asset here ? as it seems to be clearly known. similar questions for other methods too.

CannotCreate would be better?

i am not sure what else to choose from WithdrawConsequences

this would be resolved by just supporting deposits i guess

i would not implement this for the pallet. I'd consider having something in our adapters that does this.

i remember why is here ... as it completely relies on local functions - asset registry storages (asset type & location) and it is very tightly bound to it, i don't really see any advantage of moving it out now

also i would like to add new extrinsic to asset registry to register these erc20 by specifying contract address (basically write version of this function)

+1 for not having this in the pallet

why not supported?
in the implementaiton of multicurrecny, you call deposit in case of deposit ( mint ).

if you check implementation of Erc20Currency that yields unsupported as well, mby cleaner would be to call deposit implementation from multicurrency here as well?

more interesting would be to support deposit and withdraw by using some holding account (withdraw transfers to holding, deposit transfers from holding)

provides the ability for currencies pallet (and fungibles trait) to operate with the ERC20 contracts deployed in EVM
also allowed contracts can operate with substrate currencies through ERC20 precompiles
