}

Dispatchable calls.

Each variant of this enum maps to a dispatchable function from the associated module.

Variants

update_schedule(Schedule<T>)

Updates the schedule for metering contracts.

The schedule must have a greater version than the stored schedule.

put_code(Vec<u8>)

Stores the given binary Wasm code into the chain’s storage and returns its codehash. You can instantiate contracts only with stored code.

call(<T::Lookup as StaticLookup>::Source, BalanceOf<T>, Gas, 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(BalanceOf<T>, Gas, CodeHash<T>, Vec<u8>, Vec<u8>)

Instantiates a new contract from the code_hash generated by put_code, optionally transferring some balance.

The supplied salt is used for contract address deriviation. See fn contract_address.

Instantiation is executed as follows:

• 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 ctor_code is executed in the context of the newly-created account. Buffer returned after the execution is saved as the code of the account. That code will be invoked upon any call received by this account.
• The contract is initialized.

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 payed 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.
