Contains one variant per dispatchable that can be called by an extrinsic.

Variants

call(<T::Lookup as StaticLookup>::Source, <<T as Config>::Currency as Currency<<T as Config>::AccountId>>::Balance, Weight, Vec<u8>)

Makes a call to an account, optionally transferring some balance.

• If the account is a smart-contract account, the associated code will be executed and any value will be transferred.
• If the account is a regular account, any value will be transferred.
• If no account exists and the call value is not less than existential_deposit, a regular account will be created and any value will be transferred.

instantiate_with_code(<<T as Config>::Currency as Currency<<T as Config>::AccountId>>::Balance, Weight, Vec<u8>, Vec<u8>, Vec<u8>)

Instantiates a new contract from the supplied code optionally transferring some balance.

This is the only function that can deploy new code to the chain.

Parameters

• endowment: The balance to transfer from the origin to the newly created contract.
• gas_limit: The gas limit enforced when executing the constructor.
• 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. See Pallet::contract_address.

Instantiation is executed as follows:

• The supplied code is instrumented, deployed, and a code_hash is created for that code.
• If the code_hash already exists on the chain the underlying code 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 endowment is transferred to the new account.
• The deploy function is executed in the context of the newly-created account.

instantiate(<<T as Config>::Currency as Currency<<T as Config>::AccountId>>::Balance, Weight, <T as Config>::Hash, Vec<u8>, Vec<u8>)

Instantiates a contract from a previously deployed wasm binary.

This function is identical to Self::instantiate_with_code but without the code deployment step. Instead, the code_hash of an on-chain deployed wasm binary must be supplied.

claim_surcharge(T::AccountId, Option<T::AccountId>)

Allows block producers to claim a small reward for evicting a contract. If a block producer fails to do so, a regular users will be allowed to claim the reward.

In case of a successful eviction no fees are charged from the sender. However, the reward is capped by the total amount of rent that was paid by the contract while it was alive.

If contract is not evicted as a result of this call, Error::ContractNotEvictable is returned and the sender is not eligible for the reward.
