Expand description
Instantiates a new contract from the supplied code
optionally transferring
some balance.
This dispatchable has the same effect as calling [Self::upload_code
] +
[Self::instantiate
]. Bundling them together provides efficiency gains. Please
also check the documentation of [Self::upload_code
].
Parameters
value
: The balance to transfer from theorigin
to the newly created contract.gas_limit
: The gas limit enforced when executing the constructor.storage_deposit_limit
: The maximum amount of balance that can be charged/reserved from the caller to pay for the storage consumed.code
: The contract code to deploy in raw bytes.data
: The input data to pass to the contract constructor.salt
: Used for the address derivation. SeePallet::contract_address
.
Instantiation is executed as follows:
- The supplied
code
is deployed, and acode_hash
is created for that code. - If the
code_hash
already exists on the chain the underlyingcode
will be shared. - The destination address is computed based on the sender, code_hash and the salt.
- The smart-contract account is created at the computed address.
- The
value
is transferred to the new account. - The
deploy
function is executed in the context of the newly-created account.
