orchestration - ICA Controller - deposit payment to ICA

[0xpatrickdev]

1. As new user of an orchestration contract, I need to “deposit” (move) my fungible funds into a place controlled by orchestration so it can do things with it.

   • for assets starting on Agoric in a smart-wallet

     • Only chains available through vbank (by BLD stakers)

   • for assets starting on a remote Cosmos chain [into an agoric-controlled-ICA on the same remote chain]

     • Contract notified of funds received in order to act see https://github.com/Agoric/agoric-sdk/issues/9968
     • for assets starting on an external chain (no ICA)

2. As a user of an orchestration contract, I need to withdraw assets from a LocalChain Account and ICA into my smart wallet

The way I currently imagine this might work - is with an LCA and IBC Transfer:

• E(chainAccount).deposit(payment)
• ChainAccount sees if a LocalChainAccount is available in state. If not, one is requested.
• E(LocalChainAccount).deposit(pmt)
• E(LocalChainAccount).transfer(chainAccountAddr, amount)

this only works for brands that are registered in the vbank by BLD staker governance. Does that suffice?

   const allegedPurse = E(bankAcct).getPurse(allegedBrand); 

p.s. see #9211

(tangential...)

   const allegedPurse = E(bankAcct).getPurse(allegedBrand); 

"alleged" seems misused there. The caller relies on the bankManager, right? it's not in a position to be suspicious of it. Seems like the result of getPurse has to be presumed correct.
