Add RestrictedTransfers proxy type #735

Open hieronx opened 2 years ago

hieronx commented 2 years ago

https://github.com/centrifuge/apps/issues/718

The proxy is able to do any transfer
The proxied account with the RestrictedTransfers type is limited to a set number of accounts which funds can be sent to
The proxy can update this list of accounts

Should be able to define destinations per currency type.

Should also support limiting which destinations on other chains it can be transferred to using XCM and/or Connectors.

@offerijns didn't we already add the proxy type or is this a more complex version of https://github.com/centrifuge/centrifuge-chain/blob/4c5bb8473383f84a058f21ae0953166e156fdccc/runtime/development/src/lib.rs#L389-L414

@mustermeiszer What we already added was https://github.com/centrifuge/centrifuge-chain/issues/734. This just limited the calls which these proxy types could make. This ticket is actually having the ability to limit destinations to which a proxied account can send currency to.

Ah, I see. Well, this will need a pallet then.
