Runtime calls

Calls are categorized according to the dispatch origin they require:

1. User calls: the dispatch origin for this kind of call must be signed by the transactor. This is the only call category that can be submitted with an extrinsic.
2. Root calls: This kind of call requires a special origin that can only be invoked through on-chain governance mechanisms.
3. Inherent calls: This kind of call is invoked by the author of the block itself (usually automatically by the node).
4. Disabled calls: These calls can not be called directly, they are reserved for internal use by other runtime calls.

User calls

There are 68 user calls from 21 pallets.

Balances - 6

transfer - 0

transfer(dest, value)

dest: <T::Lookup as StaticLookup>::Source
value: T::Balance

Transfer some liquid free balance to another account.

transfer will set the FreeBalance of the sender and receiver. If the sender's account is below the existential deposit as a result of the transfer, the account will be reaped.

The dispatch origin for this call must be Signed by the transactor.

transfer_keep_alive - 3

transfer_keep_alive(dest, value)

dest: <T::Lookup as StaticLookup>::Source
value: T::Balance

Same as the transfer call, but with a check that the transfer will not kill the origin account.

transfer_all - 4

transfer_all(dest, keep_alive)

dest: <T::Lookup as StaticLookup>::Source
keep_alive: bool

Transfer the entire transferable balance from the caller account.

NOTE: This function only attempts to transfer transferable balances. This means that any locked, reserved, or existential deposits (when keep_alive is true), will not be transferred by this function. To ensure that this function results in a killed account, you might need to prepare the account by removing any reference counters, storage deposits, etc...

The dispatch origin of this call must be Signed.

• dest: The recipient of the transfer.
• keep_alive: A boolean to determine if the transfer_all operation should send all of the funds the account has, causing the sender account to be killed (false), or transfer everything except at least the existential deposit, which will guarantee to keep the sender account alive (true). #
• O(1). Just like transfer, but reading the user's transferable balance first. #

balance: <T::Currency as Currency<T::AccountId>>::Balance

Consume a oneshot account then transfer some amount to an account, and the remaining amount to another account.

• block_height: Must be a recent block number. The limit is BlockHashCount in the past. (this is to prevent replay attacks)
• dest: The destination account.
• dest_is_oneshot: If set to true, then a oneshot account is created at dest. Else, dest has to be an existing account.
• dest2: The second destination account.

index: ProposalIndex
approve: bool

Add an aye or nay vote for the sender to the given proposal.

Requires the sender to be a member.

index: ProposalIndex
proposal_weight_bound: Weight
length_bound: u32

Close a vote that is either approved, disapproved or whose voting period has ended.

May be called by any signed account in order to finish voting and close the proposal.

If called before the end of the voting period it will only close the vote if it is has enough votes to be approved or disapproved.

If called after the end of the voting period abstentions are counted as rejections unless there is a prime member set and the prime member cast an approval.

If the close operation completes successfully with disapproval, the transaction fee will be waived. Otherwise execution of the approved operation will be charged to the caller.

• proposal_weight_bound: The maximum amount of weight consumed by executing the closed proposal.
• length_bound: The upper bound for the length of the proposal in storage. Checked via storage::read so it is size_of::<u32>() == 4 larger than the pure length.

• target: Receiver of the atomic swap.
• hashed_proof: The blake2_256 hash of the secret proof.
