Message: UpdateContractBytecode
The UpdateContractBytecode
message handler is used to update the bytecode of a contract. Only policy type 2 admin accounts are able to call this handler (i.e., a multi-sig).
The bytecode is sourced from an existing contract deployed on the chain. There are checks to ensure that the addresses exist.
Then, a check is enacted to ensure that the contract being updated is a delpoyed ZRC-20 or is the wzeta connect contract.
