what are the exact use cases where someone wants to update the metadata of a deployed contract?
@statictype The use-case is the proxy pattern, which enables upgradable contracts. Consider this example:
- You deploy a
proxycontract, this contract contains the address of another contract in it's storage. - This
proxycontract exposes oneupdate_addressmessage: an admin can update this storage item with the address of some contract. - Any other message call to the
proxycontract (besidesupdate_address) is forwarded to the stored contract address. - Users use the proxy contract with the metadata of this stored contract address. So for them it's invisible that they actually call the proxy contract first.
- In case an admin updates the address of the contract where calls are forwarded to, the metadata which users use to interact with the
proxycontract might change.
Does this clarify things?
