Expand description
Contains one variant per dispatchable that can be called by an extrinsic.
Variants
Transfer some liquid free balance to another account.
transfer
will set the FreeBalance
of the sender and receiver.
It will decrease the total issuance of the system by the TransferFee
.
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.
- Dependent on arguments but not critical, given proper implementations for input config types. See related functions below.
- It contains a limited number of reads and writes internally and no complex computation.
Related functions:
ensure_can_withdraw
is always called internally but has a bounded complexity.- Transferring balances to accounts that did not exist before will cause
T::OnNewAccount::on_new_account
to be called. - Removing enough funds from an account will trigger
T::DustRemoval::on_unbalanced
. transfer_keep_alive
works the same way astransfer
, but has an additional check that the transfer will not kill the origin account.
- Origin account is already in memory, so no DB operations for them.
Fields of transfer
dest: <T::Lookup as StaticLookup>::Source
value: T::Balance
Set the balances of a given account.
This will alter FreeBalance
and ReservedBalance
in storage. it will
also decrease the total issuance of the system (TotalIssuance
).
If the new free or reserved balance is below the existential deposit,
it will reset the account nonce (frame_system::AccountNonce
).
The dispatch origin for this call is root
.
Fields of set_balance
Exactly as transfer
, except the origin must be root and the source account may be
specified.
- Same as transfer, but additional read and write because the source account is not assumed to be in the overlay.
Fields of force_transfer
source: <T::Lookup as StaticLookup>::Source
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.
99% of the time you want transfer
instead.
Fields of transfer_keep_alive
dest: <T::Lookup as StaticLookup>::Source
value: T::Balance
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 thetransfer_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. #
Fields of transfer_all
dest: <T::Lookup as StaticLookup>::Source
keep_alive: bool
Unreserve some balance from a user by force.
Can only be called by ROOT.
Fields of force_unreserve
who: <T::Lookup as StaticLookup>::Source
amount: T::Balance
