I am looking to create a smart contact that will delegate the funds it is storing.
1) How does an originated KT address delegate to a baker? 2) If a KT address delegates, can it do anything else?
I haven't been able to find any example contracts. I am learning to develop in smartpy but will take any guidance I can get regardless of language.
1) How does an originated KT address delegate to a baker?
During the origination of a smart contract, an initial delegate can be set. After origination, only the smart contract itself can change its delegate and it does that by calling the SET_DELEGATE Michelson instruction (called sp.set_delegate in SmartPy).
2) If a KT address delegates, can it do anything else?
Yes, delegation does not affect the behavior of a smart contract.
As of 005, KT1s are not necessary for delegation. A KT1 can only have 1 code block, which it receives automatically when you delegate a KT1 (just use any wallet or the CLI to initiate this). So, KT1 can only do one thing.
If you need to do it with a proper contract, use sp.set_delegate to set or unset the delegate of a smart contract funds. https://www.smartpy.io/dev/reference.html#_key_hash.
